A 3.0-liter DOHC inline six-cylinder engine with 149 kW was used to power the Supra (200 hp; 203 PS). Some models featured with a removable Sport-Roof panel, and notable features included an electronically controlled independent suspension (known as the Toyota Electronic Modulated Suspension, or TEMS) (Targa top).

Which engine powers the vintage Supra?
Toyota started producing the Supra in Japan as the Celica XX in April 1978 and offered it alongside the Celica through dealership sales channels known as Toyota Corolla Stores in Japan.
The 2.0 L 12-valve SOHC inline-six engine with 125 PS (92 kW; 123 hp) and the 2.6 L 12-valve SOHC inline-six engine with 82 kW (110 hp; 111 PS) were both available for the Supra (4M-E, chassis code MA46). As a result of laws governing vehicle size and engine displacement, the Japanese model was fitted with the 2.0 L engine, which is smaller. The installation of the larger engine did require Japanese buyers to pay a higher annual road tax, making ownership of the car more expensive than the smaller Celica. Both engines were fitted with electronic fuel injection.[6][9]
The Supra was initially sold outside of Japan in January 1979[10]. The federalized version came with a 2.6-liter 12-valve SOHC inline-6 engine that produced 110 horsepower (82 kW; 112 PS).
The vehicle had two gearbox choices: a standard 5-speed manual transmission (W50) or an optional 4-speed automatic transmission (A40D). An overdrive gear was present in both gearboxes. The automatic transmission had an overdrive gear that would engage at speeds over 56 km/h, whereas the highest gear in the 5-speed transmission was its overdrive gear (35 mph). With the exception of the bigger F series (and optional Limited Slip Differential) in the MA46 and MA47 versions, the Supra’s drivetrain was unchanged from the Celica’s T series solid rear axle arrangement. The vehicle also had a four-link rear suspension with coil springs, a lateral track bar, and a stabilizer bar, as well as standard 4-wheel disc brakes. A stabilizer bar and MacPherson struts made up the front suspension.
Power windows and power locks were available as part of the convenience package for the Supra’s interior. Along with cruise control and unique door decor with door pull straps, the convenience package also offered an optional sunroof. Standard features included a flip-top armrest with storage and an extendable map lamp in the center console. The tilt steering wheel, large zippered pockets on the backs of the front seats, and a tonneau cover beneath the liftback were additional features. A modern AM/FM/MPX 4-speaker stereo radio, an analog clock, and a tachometer were also included in the instrument panel on the dashboard.
What model year is Supra’s 1JZ?
The Supra was a more potent version of the standard Celica, but in 1986 Toyota formally split the Supra and Celica off to create two separate vehicles. This Supra is the A70, or Mark III. Despite having such a rich history, the first three Supra versions never truly stood out in terms of performance. The inline-6 engine was hardly sufficient, and even the A70 was heavy. After that, someone made the decision to add a turbocharger to the engine, resulting in the 7MGTE. The party got underway with a turbo.
Toyota renamed the vehicle the “Supra Turbo,” giving it 230 horsepower, and it started to gain traction in the competitive sports car market. Then, in 1992, the 1JZ engine entered the picture as a double whammy. The Supra became even better with the new inline-6, especially when it was turbocharged.
We all know that it continued after that. Toyota followed up the Mark III Supra with the iconic Mark IV Supra, also known as the A80. It replaced the dated, boxy design of earlier Supras with an appearance that is highly contemporary. The initial models went on the road in 1993, and they continue to look modern. Naturally, it also came with the nearly indestructible 2JZ inline-6 engine.
The vehicle would develop such a cult following that, despite being removed from the American market in 1998, it was selected as the star vehicle for the 2001 film “The Fast and the Furious,” and the rest, as they say, is history.
Once more, the situation might not be fatal. The Mark V Supra is almost definitely coming back, and Toyota is working with BMW to produce the new sports car.
What is the value of a 1987 Supra?
**Assumption based on an original stock 1987 Toyota Supra Mk III valued at $13,600 with ON rates and $100/300K liability/UM/UIM limitations. Actual costs vary according on the coverage chosen, the state of the vehicle, the province, and other elements.
What makes 2JZ so strong?
Why is the Toyota 2JZ inline-6 engine a renowned engine in the automobile industry? A brand-new video delves deep into the engine’s internals and explains why it’s so perfect for producing significant power with stock internals.
The engine in the video is essentially the same engine that was in the last Toyota Supra, which is from Papadakis Racing. Its variable camshaft timing on the intake comes from a Toyota Aristo, also known as the Lexus GS in the United States. The remainder of the movie essentially demonstrates how the engine was disassembled, but while doing so, we can see what makes the engine unique. We may thank Japan’s bubble economy for the over-engineered, extraordinarily long-lasting engines that the auto industry produces.
The 2JZ engine is quite durable to begin with because it has a cast-iron block and a closed block. The engine is equipped with bucket-type lifters, which are highly dependable but don’t fit larger camshafts effectively. The number of moving parts is significantly less than, say, a rocker arm system. The head gasket itself appears to be in decent condition for an engine that has been in use for more than 20 years when the head is removed.
Toyota equipped the 2JZ with extremely durable head gaskets and a closed block design, which contributes to the problem. The absence of water openings all around the cylinders makes them incredibly durable. Because of this, tuners can extract a lot of power and boost from the standard internals. Three layers of steel make up the multi-layer head gasket itself. The construction helps create a very tight seal around the cylinder and prevents the gasket from blowing.
For the mechanical types, the rest of the film is pure zen, so relax and take in the teardown above.
Why is 2JZ so well-liked?
The 2JZ engine, a storied engine in the tuner scene, is what gave the last year of the Supra its enormous popularity. The closed, over-engineered engine design enables the utilization of significant boost on internals that are already in place. The 2JZ can survive a lot of punishment because to this plus the inherent durability of any inline-six engine architecture, but the best way to really appreciate how Toyota created the 2JZ to be so resilient is to go inside one.
Stephan Papadakis, owner of the wildly successful Formula DRIFT team Papadakis Racing, dissects the 2JZ engine and explains how it functions in order to examine the design.
The twin-turbo 2JZ engine was not unique to the Supra, despite it having gained popularity because to it. Toyota also employed a variation in the Aristo, a vehicle that underwent a US rebranding to become the Lexus GS. The variation Papadakis examines on screen makes use of variable camshaft timing on the intake.
There is a fairly definite take down order to it, even though a large portion of the disassembly is very much identical to disassembling any engine. The advantages of the powerhouse are evident in almost every component, working inward from the outside.
Four valves per cylinder are made possible by the dual overhead cams, which also permit a top plug design for the best spark and a superior air/fuel mixture and flow. Although this prevents the use of really aggressive cams, bucket style lifters sit on the camshaft lobes, which decreases the number of moving parts in the engine and improves reliability.
Toyota employed a multi-layered steel head gasket for this engine, which lowers the likelihood that it may blow, and a closed-block design, which supports the cylinder walls. Toyota attached a girdle to the underside of the 2JZ to increase the block’s stiffness while still allowing access to the rotating assembly. The rotating assembly is finally made practically indestructible by a forged crankshaft, a wide bearing design, and a lot of thrust bearing. It is not at all unexpected that this engine has been so successful with the tuner community.
A 2JZ is it a v8?
It’s possible to question and remove unsourced material. An assortment of inline-6 car engines make up the Toyota JZ engine family. The JZ engines, which came in 2.5- and 3.0-litre forms, were 24-valve DOHC engines designed to replace the M-series inline-6 engines.
Which Supra is a 2JZ?
Your suspicion is right if you’re asking whether the 2JZ engine has ever been used in America. The only 2JZ vehicle sold in the United States, however, lasted for just five years, from 1993 to 1998. T stands for induction through force, and the vehicle was the recognizable Supra Twin Turbo.
The vehicle had a 3.0L engine and could produce 320 horsepower at 5,600 rpm. The same had torque figures of 315 lb-ft at 4,000 rpm. For a car from the 1990s, the 100 km/h mark was reached in 5.6 seconds, which is very impressive. The automobile was incredibly quick for its era, reaching 155 mph at its top speed.
Which is superior, the 2JZ or the RB26?
GTR vs. Supra. a tasty contest. Let’s begin now! One glance at each specification sheet explains why the RB26DETT and 2JZ-GTE are both halo engines for JDM car enthusiasts: close to 300 PS and healthy torque figures in standard tune, cast iron bottom ends and low weight, 24 valve cylinder heads.
Each engine has a lot of tuning capability thanks to well-engineered mechanical design. Both are substantial inline six cylinder engines that are around the same size and weight.
The 2JZ-enlarged GTE’s displacement produces the same amount of output, but it reaches its peak power 1,200 rpm earlier than the RB26. Additionally, the 2JZ produces 31 lb ft greater torque at 400 rpm less than the RB.
What kind of HP is a 1JZ capable of?
YouTube is flooded with videos of tuned JZ engines, but instead of comparing one dyno run to another without context or funding, let’s take a look at two videos showcasing some of the craziest JZ tuning. Both engines have similar tuning potential.
JZ-GTE Dyno tuning
If this doesn’t make you love Supras, I don’t know what will. This outrageously loud 1600HP (on spray) Titan Motorsports Toyota Supra showed up at Fair Lakes Cars & Coffee this morning. The car runs 1400HP off the bottle.
Scores & conclusion
- xxxxx 2JZ-GTE
- xxxxx 1JZ-GTE
I’ll end by quoting from the wonderful essay by Dustrunnerauto:
Both are among the hottest factory engines ever to be installed in a production car.
“A general rule of thumb is that the stock 1JZ bottom end is good for about 650-700 horsepower, and the stock 2JZ bottom end is good for about 800 horsepower, so you would think that the 2JZ would be stronger then right? Wrong. Most people think that the 2JZ is stronger because it can withstand higher power levels, but they neglect to account for the extra displacement.
“650700 horsepower, or 260280 hp/liter (650 hp/2.5 liters = 260 hp/liter), is the range for the stock 1JZ bottom end. The factory 2JZ bottom end is capable of producing 800, or 266 horsepower per liter.
“The 1JZ and 2JZ can reliably push 266hp/liter on their bottom ends, by which I mean pounding the snot out of the engine for extended periods of time and it not failing. Both of these engines’ bottom ends have been pushed much above the figures I just gave.
“Both are among the hottest factory engines ever to be installed in a production car. There are very few engines in existence that have 1,000 horsepower or more.
