With this version Toyota took a big leap in the direction of a more serious high-performance car. Again using subframe, suspension,and drivetrain assemblies from the Z30 Soarer (Lexus SC300/400), test model pre-production started in December 1992 with 20 models, and official mass production began in April 1993. The new Supra was completely redesigned, with rounded body styling and featured two new engines: a naturally aspirated Toyota 2JZ-GE producing 220 hp (164 kW; 223 PS) at 5800 rpm and 210 lb·ft (280 N·m) at 4800 rpm of torque and a twin turbocharged Toyota 2JZ-GTE making 276 hp (206 kW; 280 PS) and 318 lb·ft (431 N·m) of torque for the Japanese version. The styling, while modern, does seem to borrow some elements from Toyota's first grand touring sports car, the Toyota 2000GT. For the export model (America/Europe) Toyota upgraded the Supra turbo's engine (smaller, steel wheeled turbochargers, bigger fuel injectors, etc.). This increased the power output to 320 hp (239 kW; 324 PS) at 5600 rpm and 315 lb·ft (427 N·m) at 4000 rpm. (326hp / 325lbft for Europe)
The turbocharged variant could achieve 0–60 mph in as low as 4.6 seconds and 1/4 mile (402 m) in 13.1 seconds at 109 mph (175 km/h). The turbo version was tested to reach over 285 km/h (177 mph), but the cars are restricted to just 180 km/h (112 mph) in Japan and 250 km/h (155 mph) elsewhere. European versions of the car also had an air intake or scoop on the hood. Drag coefficient is 0.31 for the naturally aspirated models and 0.32 for the turbo models but unknown with the rear spoiler.
The twin turbos operated in sequential mode, not parallel. Initially, all of the exhaust is routed to the first turbine for reduced lag. This resulted in boost and enhanced torque as early as 1800 rpm, where it already produced 300 lb·ft (410 N·m) of torque. At 3500 rpm, some of the exhaust is routed to the second turbine for a "pre-boost" mode, although none of the compressor output is used by the engine at this point. At 4000 rpm, the second turbo's output is used to augment the first turbo's output. Compared to the parallel mode, sequential mode turbos provide quicker low RPM response and increased high RPM boost. This high RPM boost was also aided with technology originally present in the 7M-GE in the form of the Acoustic Control Induction System (ACIS) which is a way of managing the air compression pulses within the intake piping as to increase power.
For this generation, the Supra received a new 6-speed Getrag/Toyota V160 gearbox on the turbo models while the naturally aspirated models made do with a 5-speed manual W58, revised from the previous version. Each model was offered with a 4-speed automatic with manual shifting mode. Turbo models were equipped with larger brakes and tires (Unless you were in Japan where these were an optional extra). All vehicles were equipped with 5-spoke aluminium alloy wheels and a space saver spare tire on a steel wheel to save weight and space.
Toyota took measures to reduce the weight of this new model. Aluminium was used for the hood, targa top (when fitted), front crossmember, oil and transmission pans, and the suspension upper A-arms. Other measures included hollow carpet fibers, magnesium-alloy steering wheel, plastic gas tank and lid, gas injected rear spoiler, and a single pipe exhaust. Despite having more features such as dual airbags, traction control, larger brakes, wheels, tires, and an additional turbo, the car was at least 200 lb (91 kg) lighter than its predecessor. The base model with a manual transmission had a curb weight of 3,210 lb (1,460 kg). The Sport Roof added 40 lb (18 kg) while the automatic transmission added 55 lb (25 kg). It had a 51:49 (front:rear) weight distribution. The turbo model weighed 3,450 lb (1,560 kg) for the manual, automatic added another 10 lb (4.5 kg). Weight distribution was 53% front/47% rear. The Supra was heavier than the spartan Mazda RX-7 and all aluminium bodied Acura/Honda NSX, but it was lighter than the Nissan 300ZX and Mitsubishi 3000GT VR-4.
For the 1996 model year in the US, the turbo model was only available with the automatic transmission owing to OBD-II certification requirements. The targa roof was also made standard on all turbo models. For 1997, manual transmission returned for the optional engine along with a redesign of the tail lights, headlights, front fascia, chromed wheels, and other minor changes such as the radio and steering wheel designs. All 1997 models included badges indicating "Limited Edition 15th Anniversary". All turbo models came standard with the rear spoiler. For 1998, updates were a 3-spoke steering wheel and redesigned radio. In Japan, the turbo engines were installed with VVT-i. The SZ-R model was also updated with the introduction of a six-speed Getrag V161 transmission, the same used for the twin-turbo RZ models.
The stock A80 Supra chassis has also proven an effective platform for roadracing, with several top 20 and top 10 One Lap Of America finishes in the SSGT1 class. Despite its curb weight, in 1994 the A80 managed remarkable skidpad ratings of 0.95 lateral g's (200 ft) and 0.98 lateral g's (300 ft) Supra also featured a four-sensor four-channel track tuned ABS system with yaw control whereby each caliper is sensored and the brakes are controlled individually according to the speed, angle, and pitch of the approaching corner. This unique Formula One-inspired braking system allowed the Supra Turbo to record a 70 mph (113 km/h) -0 braking distance of 149 ft (45 m), the best braking performance of any production car tested in 1997 by Car and Driver magazine. This record was finally broken in 2004 by a Porsche Carrera GT, which does it in 145 ft (44 m) .
The US and UK market Supra featured bigger injectors, steel turbines and bigger inlet cam and had emissions in the range of 259 g/km CO2 despite the addition of Exhaust Gas Recirculation (EGR). The Japanese market Supra had CO2 emissions in the range of 224 g/km.
By the late 90s, sales of all sporty coupes were declining in North America, so the Supra was withdrawn from the Canadian market in 1996 and the US in 1998. The Turbo was not available in 1998 in California Air Resources Board (CARB) states. Production continued in Japan until August 2002, ceasing owing to restrictive emission standards.

EQ5 equatorial mount, Nikon D300, 50 mm prime lens @ f/4, 1000 ISO, 18 subframes, 2 minutes each. The meteor appeared at about 2:39 hrs local time.
The Cocoon Nebula, IC 5146, in Cygnus. 18 x 10' subframes captured on 8-28-2014 at the General Nathan Twinning Observatory in Belen, New Mexico using an SBIG ST4000XCM on a Celestron C11 Edge with f/7 focal reducer (1960 mm focal length) on a Losmandy G11 mount. Processing was done in DSS and Photoshop CS2.
As I reviewed the subframes one by one I noticed a distortion in the noise pattern. It's difficult to see but it's about a fourth of the way from the left and a fourth of the way from the top. (If you can't see it, the next image I post will make it clear.)
I almost deleted the subframe because of it, but instead checked preceding and succeeding subframes for patterns.
This is going to be difficult to see on a small screen like a smartphone. Best viewed on a large desktop display.

clearly marked.
I will say this about the paint job on 6006, the subframe details really stand out clearly. Something about this scheme is a little too "model railroady" for my tastes. If the trucks and fuel tank had been black there'd be a better contast in hues. I hate to say this, living along the CN, but I suspect this unit will look better with a little weathering. Regardless, it's great to see the WGN pick up the switching on this line. They've been tenacious about keeping the tracks in service to Spooner that would have otherwise been removed or grown in beyond retrieval. November 12, 2014.
Initially based on the rear-wheel drive X-body platform that underpinned the Chevrolet Nova (a unibody with a bolt-on subframe — this layout was common with both GM X and F bodies), the Seville's unibody and chassis were extensively re-engineered and upgraded from that humble origin and it was awarded the unique designation of "K-body". Cadillac stylists added a crisp, angular body that set the tone for GM styling for the next decade, along with a wide-track stance that gave the car a substantial, premium appearance. A wide chrome grille flanked by quad rectangular headlamps with narrow parking and signal lamps just below filled the header panel, while small wrap-around rectangular tail lamps placed at the outmost corners of the rear gave the appearance of a lower, leaner, and wider car. The wrap-around taillights might have came from a design sketch of a Coupe DeVille concept which was rejected (the concept can be seen in the March 2008 issue of Collectible Automobile detailing the 1977 GM full-size cars).
Seville engineers chose the X-body platform instead of the German Opel Diplomat in response to GM's budget restrictions — GM executives felt that reengineering a German Opel would be more costly than the corporate X-car. Another proposal during the development of the Seville was a front-wheel drive layout similar to the Cadillac Eldorado. This proposal also met with budget concerns since the transaxle used for the Eldorado was produced on a limited basis solely for E-body (Eldorado/Toronado) production, alongside the GMC motorhome of the mid-1970s (which has a derivative of the E-platform drivetrain).
This was the first time Cadillac began engineering one of its vehicles based on components previously used in a Chevrolet model.
Introduced in mid-1975 and billed as the new "internationally-sized" Cadillac, the Seville was almost 1,000 lb (450 kg) lighter than the hulking Deville; nimble, easy to park, attractive and loaded with the full complement of Cadillac gadgets. More expensive than every other Cadillac model at US$12,479, the Seville was a smash hit, and spawned several imitators, such as the less-than-successful Lincoln Versailles, and later the Chrysler LeBaron/Fifth Avenue.
Early Sevilles produced between April 1975 (a total of 16,355) to the close of the 1976 model year were the first Cadillacs to use the Chevrolet passenger car wheel bolt pattern (5 lugs with a 4.75 in (121 mm) bolt circle; the 2003-present XLR also uses the Chevrolet pattern). The first Sevilles shared only a strict minority of components with the engineering starting point, the GM X-Body. The rear drums measured 11 in (280 mm) and were similar to the ones used with the Chevrolet Nova 9C1 (police option) and A-body (Chevelle, Cutlass, Regal, LeMans) intermediate station wagons. Starting with the 1977 model year, production Sevilles used the larger 5 lug — 5 inch bolt circle common to full-size Cadillacs, Buicks, Oldsmobiles, Pontiacs, and 1/2 ton Chevrolet/GMC light trucks and vans. It also received rear disc brakes, a design which would surface a year later as an option on the F-body Pontiac Trans Am.
Under the hood went an Oldsmobile-sourced 350 in³ (5.7L) V8, fitted with Bendix/Bosch electronically controlled fuel injection. This system gave the Seville smooth drivability and performance that was usually lacking in other domestic cars of this early emissions control era. Power output was 180 hp, and performance was restrained with the 60 mph (97 km/h) sprint taking 11.5 seconds. A diesel 350 in³(5.7 L) LF9 V8 was added in 1978, but that engine was known to be poor in both performance and reliability.
A unique optional feature available only during the 1979 model year was the Cadillac Trip Computer. This option offered an electronic readout for the speedometer and remaining fuel which replaced the standard needle-type gauges. It also included a host of calculations available at the touch of a button on a small panel located just to the right of the steering wheel. These included miles to empty, miles per gallon, and a destination arrival time, which needed to be programmed by the driver, to estimate arrival time based on miles remaining. This system predated Lincoln's system by one year. A digital instrument cluster was available on the Seville and Eldorado again in their 1981 through 1985 configurations, though the "Trip Computer" was no longer available. This option added US$920 to the price of Seville in 1979.
The Seville Cadillac was manufactured in Iran under the brand name of "Cadillac Iran" during 1970s and 1980s, by Pars Khodro, which was known as "Iran General Motors" in 1970s.
The Sheridan Theatre
4036 N. Sheridan Road, Chicago, IL 60613
A Balban & Katz Theatre.
The Sheridan Theatre had 3,000 seats
in its balconied auditorium, which featured,
like San Francisco’s Castro Theatre,
a mock-tented ceiling, ringed by a Roman-style freize depicting a procession of gods.
The Sheridan Theatre also had a small stage,
an orchestra pit and a Wurlitzer organ, opened by organist Edmund Fitch.
Unlike Pridmore’s other theatres, which were mostly Atmospheric in style, the Sheridan Theatre was a Neo-Classical/Italian Baroque combination, complete with Corinthian columns, Roman statuary, and a proscenium arch topped by golden lions supporting a crowned shield.
By 1929 it had been taken over by Fox Theatres & renamed Fox Sheridan Theatre.
In early-1934 it was taken over by Essaness (Charlie Chaplain's Company) Theatres Corp.
After the Sheridan Theatre was closed in 1951, it was acquired by a synagogue (Anshe Emmet) which used the former theatre for their house of worship for 15 years, until moving.
Demolished in The 1990's.

www.1001pallets.com/2016/09/adjustable-upholstered-pallet...
I love the inspiration I find on 1001pallets.com, So, I made an Adjustable Upholstered Pallet Lounge Chair. My simple design took about four hours and ten dollars. I wanted to make an adjustable lounger, but needed it to be a bit more comfortable, so I integrated the idea of upholstering instead of a removable cushion.
Here’s my Adjustable Upholstered Pallet Lounge Chair – the subframe:
First, I broke apart a single large pallet and used a couple of leftover pieces from another. I set the pallet stringers aside, as they will become the frame, and cleaned up the deck boards. I cut the two long stringers down to the length of the chair I wanted – but you can make it as long or short as you want. The stringers have the arches for the forklift, but I think that adds a crafter-feel to it.
With the remaining portions that I cut off, I turned them into legs by cutting them at slight angles. I mounted them to the insides of the stringers with long deck screws. Next, I cut two more pieces of stringer as braces to the front and back leg set to stabilize the legs and the horizontal frame pieces I dry-fit to check it but did NOT mount the two pieces together yet. Finally, I cut another scrap bit of wood as a lower brace to hold the legs from flexing out too far, checked for fit, and set it aside for now.
Adjustable Upholstered Pallet Lounge Chair – the backrest frame pivot and cross-supports:
The backrest doesn’t necessarily need the heavy stringer boards as support, but you do need something strong enough to support yourself safely so that 2x4 boards would work fine too. I cut two pieces long enough to make the seat back to the height I wanted, plus about five inches to create the hinge points and for rounding over at the ends. I sanded and rounded them over at both ends.
Next, I cut two pieces of leftover dowel rods. 1) The upper dowel rod (midway up the backrest) was cut to the external width of the backrest boards (or the inside width of the sub-frame so it’ll lay almost flat) plus about ½” extra on each end to be inserted into the bar adjuster arms. 2) The lower dowel rod needs to be cut wide enough to go through the backrest boards and into the subframe approximately ¾” on each side. Then I laid the pieces out on a table and checked for square, and marked where I needed to drill for the upper and lower holes. Allow enough extra at the lower holes for rounding, so it’s not too thin and then breaks.
Adjustable Upholstered Pallet Lounge Chair – Swinging support arm:
I cut a deck board piece in half lengthwise and then trimmed to the length I wanted by finding out how high up I wanted the chair to sit. This is based on where you mount it and how high up you want the chair to sit. I just held up the backrest and used a scrap board to prop it in place to check it, then took my measurements and cut the legs. Add a little bit of length because you’ll have to plan for mounting the board to the upper dowel – so you’ll be drilling holes part-way through the boards AND you’ll be rounding over the end, so it doesn’t bind up.
Adjustable Upholstered Pallet Lounge Chair –Drilling the holes:
Backrest boards: Drill both sets of holes all the way through and clean up the holes. You can use a hole saw bit set or a Forstner bit & drill press would make faster and more accurate work of it. The hole needs to be a big enough diameter to allow the dowel to slide easily through and not bind up so you can adjust the seat height with one hand.
Here's one way to drill a hole - a Forstner Bit. You can use a hole saw, but you'd have to chisel out the excess. This will leave a little centering drill hole, but it won't show.
Sub-frame boards: Drill a hole approximately ¾” deep on the INSIDE of the subframe, but don’t go all the way through. These holes will accommodate the dowel rod that will go through the backrest boards. It’ll allow the whole backrest to pivot without any hardware.
The swinging support arm (the U-shaped piece): Drill a hole approximately ½ to ¾” deep (depending on the thickness of your board). Don’t drill all the way through. The holes will stabilize the dowel, but will also help capture it to keep it in place.
Adjustable Upholstered Pallet Lounge Chair – the backrest frame assembly part 1:
I laid out the backrest and got it square/straight. Next, I slid the dowel rods through the backrest holes. I applied a bit of PVA glue into the inside holes of the swinging arm support (the U-shaped piece) but was sparing with it. Then I pre-drilled and secured the swinging arm support to the dowel rod. Now you can insert the lower dowel rod through the backrest supports and into the sub-frame.
Adjustable Upholstered Pallet Lounge Chair – the backrest frame assembly part 2:
Install the cross-braces to the sub-frame and the front and back legs. Add the lower, thinner cross-braces to the legs to keep them from flexing in or out. Double-check that your backrest pivots the way you want. If everything is good, do a final tightening.
Adjustable Upholstered Pallet Lounge Chair –Backrest stops and a spring:
To set the backrest stops, hold the backrest up and move the swinging arm support out to try it. Mark it with a pencil and use scrap pieces to create a stop. Screw to the tops of the subframe rails. Repeat this, however, many times you want. You can glue them in place and secure them with fasteners too. I added a metal bracket with a loop attached (like a drawer pull) for a place to hook the spring. The spring was mounted to the sub-frame cross-brace. I did this so that when I move the chair I can turn it on the side and the backrest won’t flop around. This is optional but suggested if you move the chair a lot.
Adjustable Upholstered Pallet Lounge Chair – Topping it off:
Now, for the fun and fast part – covering the seat and seat back. I measured and cut my boards to the width I wanted. You could use a jig for your chop saw if you chose. If you have a larger table saw setup, you can set your fence to the width you want. Cut all your pieces and install them after pre-drilling. Secure with fasteners.
Adjustable Upholstered Pallet Lounge Chair – Upholstery:
I used foam pieces – about 3” thick and trimmed them to the width of the seat and backrests. Next, I also cut a piece to fit in between the backrest and seat This filled the big gap. I trimmed the thick vinyl (or use whatever you want) to cover the foam, plus enough to secure on the backs with a staple gun. You can pre-glue or not. Finally, I covered it all and secured it in place with staples. I added a headrest pillow by applying a second layer of foam and covered it. Now I have a comfy, Adjustable Upholstered Pallet Lounge Chair.
Here's my chair, not upholstered yet, but fully assembled and in an upright position.
Here's a side-view and a better shot of the chair, fully assembled, with the deck boards installed. I have it in the fully upright position, You can see the gap that I will fill later with the upholstery.
Finished project - with upholstery installed.
With this version Toyota took a big leap in the direction of a more serious high-performance car. Again using subframe, suspension,and drivetrain assemblies from the Z30 Soarer (Lexus SC300/400), test model pre-production started in December 1992 with 20 models, and official mass production began in April 1993. The new Supra was completely redesigned, with rounded body styling and featured two new engines: a naturally aspirated Toyota 2JZ-GE producing 220 hp (164 kW; 223 PS) at 5800 rpm and 210 lb·ft (280 N·m) at 4800 rpm of torque and a twin turbocharged Toyota 2JZ-GTE making 276 hp (206 kW; 280 PS) and 318 lb·ft (431 N·m) of torque for the Japanese version. The styling, while modern, does seem to borrow some elements from Toyota's first grand touring sports car, the Toyota 2000GT. For the export model (America/Europe) Toyota upgraded the Supra turbo's engine (smaller, steel wheeled turbochargers, bigger fuel injectors, etc.). This increased the power output to 320 hp (239 kW; 324 PS) at 5600 rpm and 315 lb·ft (427 N·m) at 4000 rpm. (326hp / 325lbft for Europe)
The turbocharged variant could achieve 0–60 mph in as low as 4.6 seconds and 1/4 mile (402 m) in 13.1 seconds at 109 mph (175 km/h). The turbo version was tested to reach over 285 km/h (177 mph), but the cars are restricted to just 180 km/h (112 mph) in Japan and 250 km/h (155 mph) elsewhere. European versions of the car also had an air intake or scoop on the hood. Drag coefficient is 0.31 for the naturally aspirated models and 0.32 for the turbo models but unknown with the rear spoiler.
The twin turbos operated in sequential mode, not parallel. Initially, all of the exhaust is routed to the first turbine for reduced lag. This resulted in boost and enhanced torque as early as 1800 rpm, where it already produced 300 lb·ft (410 N·m) of torque. At 3500 rpm, some of the exhaust is routed to the second turbine for a "pre-boost" mode, although none of the compressor output is used by the engine at this point. At 4000 rpm, the second turbo's output is used to augment the first turbo's output. Compared to the parallel mode, sequential mode turbos provide quicker low RPM response and increased high RPM boost. This high RPM boost was also aided with technology originally present in the 7M-GE in the form of the Acoustic Control Induction System (ACIS) which is a way of managing the air compression pulses within the intake piping as to increase power.
For this generation, the Supra received a new 6-speed Getrag/Toyota V160 gearbox on the turbo models while the naturally aspirated models made do with a 5-speed manual W58, revised from the previous version. Each model was offered with a 4-speed automatic with manual shifting mode. Turbo models were equipped with larger brakes and tires (Unless you were in Japan where these were an optional extra). All vehicles were equipped with 5-spoke aluminium alloy wheels and a space saver spare tire on a steel wheel to save weight and space.
Toyota took measures to reduce the weight of this new model. Aluminium was used for the hood, targa top (when fitted), front crossmember, oil and transmission pans, and the suspension upper A-arms. Other measures included hollow carpet fibers, magnesium-alloy steering wheel, plastic gas tank and lid, gas injected rear spoiler, and a single pipe exhaust. Despite having more features such as dual airbags, traction control, larger brakes, wheels, tires, and an additional turbo, the car was at least 200 lb (91 kg) lighter than its predecessor. The base model with a manual transmission had a curb weight of 3,210 lb (1,460 kg). The Sport Roof added 40 lb (18 kg) while the automatic transmission added 55 lb (25 kg). It had a 51:49 (front:rear) weight distribution. The turbo model weighed 3,450 lb (1,560 kg) for the manual, automatic added another 10 lb (4.5 kg). Weight distribution was 53% front/47% rear. The Supra was heavier than the spartan Mazda RX-7 and all aluminium bodied Acura/Honda NSX, but it was lighter than the Nissan 300ZX and Mitsubishi 3000GT VR-4.
For the 1996 model year in the US, the turbo model was only available with the automatic transmission owing to OBD-II certification requirements. The targa roof was also made standard on all turbo models. For 1997, manual transmission returned for the optional engine along with a redesign of the tail lights, headlights, front fascia, chromed wheels, and other minor changes such as the radio and steering wheel designs. All 1997 models included badges indicating "Limited Edition 15th Anniversary". All turbo models came standard with the rear spoiler. For 1998, updates were a 3-spoke steering wheel and redesigned radio. In Japan, the turbo engines were installed with VVT-i. The SZ-R model was also updated with the introduction of a six-speed Getrag V161 transmission, the same used for the twin-turbo RZ models.
The stock A80 Supra chassis has also proven an effective platform for roadracing, with several top 20 and top 10 One Lap Of America finishes in the SSGT1 class. Despite its curb weight, in 1994 the A80 managed remarkable skidpad ratings of 0.95 lateral g's (200 ft) and 0.98 lateral g's (300 ft) Supra also featured a four-sensor four-channel track tuned ABS system with yaw control whereby each caliper is sensored and the brakes are controlled individually according to the speed, angle, and pitch of the approaching corner. This unique Formula One-inspired braking system allowed the Supra Turbo to record a 70 mph (113 km/h) -0 braking distance of 149 ft (45 m), the best braking performance of any production car tested in 1997 by Car and Driver magazine. This record was finally broken in 2004 by a Porsche Carrera GT, which does it in 145 ft (44 m) .
The US and UK market Supra featured bigger injectors, steel turbines and bigger inlet cam and had emissions in the range of 259 g/km CO2 despite the addition of Exhaust Gas Recirculation (EGR). The Japanese market Supra had CO2 emissions in the range of 224 g/km.
By the late 90s, sales of all sporty coupes were declining in North America, so the Supra was withdrawn from the Canadian market in 1996 and the US in 1998. The Turbo was not available in 1998 in California Air Resources Board (CARB) states. Production continued in Japan until August 2002, ceasing owing to restrictive emission standards.

This miniland-scale Lego Toyota Supra A80 Coupe has been created for Flickr LUGNuts' 92nd Build Challenge, - "Stuck in the 90's", - all about vehicles from the decade of the 1990s.
The Jimini is a Mini based car, utilising the suspension and mechanical components throughout. The front and rear subframes bolt to the new GRP bodyshell, utilising the existing Mini engine, transmission and suspension. The whole windscreen and dash assembly can be put together on a bench and then fitted to the car once complete. This enables the Jimini to be built without the builder having to perform impossible contortions to wire up the instruments under the dash.
With the fourth generation of the Supra, Toyota took a big leap in the direction of a more serious high performance car. Again using subframe, suspension and drivetrain assemblies from the Z30 Soarer (Lexus SC300/400), test model pre-production started in December 1992 with 20 models, and official mass production began in April 1993.[12] The new Supra was completely redesigned, with rounded body styling and featured two new engines: a naturally aspirated 2JZ-GE producing 220 hp (164 kW; 223 PS) at 5800 rpm and 210 ft·lb (280 N·m) at 4800 rpm of torque and a twin turbocharged 2JZ-GTE making 276 hp (206 kW; 280 PS) and 318 ft·lb (431 N·m) of torque for the Japanese version. For the export model (America/Europe) Toyota upgraded the Supra turbo's engine (smaller, steel wheeled turbochargers, bigger fuel injectors, etc.). This increased the power output to 320 hp (239 kW; 324 PS) at 5600 rpm and 315 ft·lb (427 N·m) at 4000 rpm. The turbocharged variant could achieve 0–60 mph in as low as 4.6 seconds and 1/4 mile (402 m) in 13.1 seconds at 109 mph (175 km/h)[2]. The turbo version was tested to reach over 280 km/h (174 mph) all-stock, but the cars are restricted to just 180 km/h (112 mph) in Japan and 250 km/h (155 mph) elsewhere. European versions also had an air intake on the bonnet (hood). Drag coefficient is .31 for the naturally aspirated models and .32 for the turbo models and N/A's with the rear spoiler.
The MKIV Supra's twin turbos operated in sequential mode instead of the more common parallel mode. The sequential setup featured a pair of CT-12b turbos (for the usdm market, JDM market was CT20/Ct20A with variations- some are ceramic- notorious, some are not. For UK and USDM market steel blades (CT-12b).

From Wikipedia:
The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. Its distance is 31 million light-years away from Earth.
The galaxy and its companion, NGC 5195, are easily observed by amateur astronomers, and the two galaxies may be seen with binoculars. The Whirlpool Galaxy has been extensively observed by professional astronomers, who study it to understand galaxy structure (particularly structure associated with the spiral arms) and galaxy interactions.
What later became known as the Whirlpool Galaxy was discovered on October 13, 1773, by Charles Messier. Its companion galaxy, NGC 5195, was discovered in 1781 by Pierre Méchain, although it was not known whether it was interacting or merely another galaxy passing at a distance. In 1845, William Parsons, 3rd Earl of Rosse, employing a 72-inch (1.8 m) reflecting telescope at Birr Castle, Ireland, found that the Whirlpool possessed a spiral structure, the first "nebula" to be known to have one. These "spiral nebulae" were not recognized as galaxies until Edwin Hubble was able to observe Cepheid variables in some of these spiral nebulae, which provided evidence that they were so far away that they must be entirely separate galaxies.
The advent of radio astronomy and subsequent radio images of M51 unequivocally demonstrated that the Whirlpool and its companion galaxy are indeed interacting. Sometimes the designation M51 is used to refer to the pair of galaxies, in which case the individual galaxies may be referred to as M51a (NGC 5194) and M51b (NGC 5195).
In January 2005 the Hubble Heritage Project constructed a 11,477 × 7,965-pixel composite image of M51 using Hubble's ACS instrument. The image highlights the galaxy's spiral arms, and shows detail into some of the structures inside the arms.
The Whirlpool Galaxy lies 28 million light-years from Earth and has an estimated diameter of 76,000 light-years. Overall the galaxy is about 43% the size of the Milky Way. Its mass is estimated to be 160 billion solar masses, or around 10.3% of the mass of Milky Way Galaxy.
A black hole, once thought to be surrounded by a ring of dust, but now believed to be partially occluded by dust instead, exists at the heart of the spiral. A pair of ionization cones extend from the active galactic nucleus.
The pronounced spiral structure of the Whirlpool Galaxy is believed to be the result of the close interaction between it and its companion galaxy NGC 5195, which may have passed through the main disk of M51 about 500 to 600 million years ago. In this proposed scenario, NGC 5195 came from behind M51 through the disk towards the observer and made another disk crossing as recently as 50 to 100 million years ago until it is where we observe it to be now, slightly behind M51.
The central region of M51 appears to be undergoing a period of enhanced star formation. The present efficiency of star formation, defined as the ratio of mass of new stars to the mass of star-forming gas, is only ~1%, quite comparable to the global value for the Milky Way and other galaxies. It is estimated that the current high rate of star formation can last no more than another 100 million years or so.
Three supernovae have been observed in the Whirlpool Galaxy:
--In 1994, SN 1994I was observed in the Whirlpool Galaxy. It was classified as type Ic, indicating that its progenitor star was very massive and had already shed much of its mass, and its brightness peaked at apparent magnitude 12.91.
--In June 2005 the type II supernova SN 2005cs was observed in the Whirlpool Galaxy, peaking at apparent magnitude 14.
--On 31 May 2011 a type II supernova was detected in the Whirlpool Galaxy, peaking at magnitude 12.1. This supernova, designated SN 2011dh, showed a spectrum much bluer than average, with P Cygni profiles, which indicate rapidly expanding material, in its hydrogen-Balmer lines. The progenitor was probably a yellow supergiant and not a red or blue supergiant, which are thought to be the most common supernova progenitors.
On 22 January 2019, a supernova impostor, designated AT2019abn, was discovered in Messier 51. The transient was later identified as a luminous red nova. The progenitor star was detected in archival Spitzer Space Telescope infrared images. No object could be seen at the position of the transient in archival Hubble images, indicating that the progenitor star was heavily obstructed by interstellar dust. 2019abn peaked at magnitude 17.
In September 2020, the detection by the Chandra X-ray Observatory of a candidate exoplanet, named M51-ULS-1b, orbiting the high-mass X-ray binary M51-ULS-1 in this galaxy was announced. If confirmed, it would be the first known instance of an extragalactic planet, a planet outside the Milky Way Galaxy. The planet candidate was detected by eclipses of the X-ray source (XRS), which consists of a stellar remnant (either a neutron star or a black hole) and a massive star, likely a B-type supergiant. The planet would be slightly smaller than Saturn and orbit at a distance of some tens of astronomical units.
NGC 5195 (also known as Messier 51b or M51b) is a dwarf galaxy that is interacting with the Whirlpool Galaxy (also known as M51a or NGC 5194). Both galaxies are located approximately 25 million light-years away in the constellation Canes Venatici. Together, the two galaxies are one of the most widely studied interacting galaxy pairs.
The Whirlpool Galaxy is the brightest galaxy in the M51 Group, a small group of galaxies that also includes M63 (the Sunflower Galaxy). This small group may actually be a subclump at the southeast end of a large, elongated group that includes the M101 Group and the NGC 5866 Group, although most group identification methods and catalogs identify the three groups as separate entities.
