Would a Toyota supra engine fit in a 93 Toyota MR2?

Answer 1

Nope, not even close. Even though you did not specify what year Supra, most people know of the 2JZ (actuallly called the 2JZ-GTE) from the FastNFurious first movie. The 2JZ is an INLINE 6 displacing 3.0L and has sequential Twin Turbos.

The main problem with fitting it into the 93 MR2 is that the MR2 was designed for a transversely mounted 4 cylinder. The base 4 cylinder in the MR2 is the 5S-FE from the same era of Camry. The MR2 Turbo used the 3S-GTE from the earlier Celica All-Trac.

Transversely mounted 6 cylinder Toyota engines happen to fit. The 3VZ-FE from the Camry/ES300 fits, as does the 1MZ-FE from the same car. Interestingly, the 5VZ-FE from the Tacoma will fit as well.

The Supra 2JZ-GTE is 6 cylinders long and was mounted longitudinally in the Supra. If you turn it sideways to try to fit into the MR2, the engine bay is not nearly wide enough. You also have to find a transaxle that can take the torque of the 2JZ, which would kill the stock MR2 or MR2 Turbo transaxles, and you need whatever transaxle you use to bolt up to the 2JZ, or you willl need an adaptor plate, which makes the problem even worse. You would discover that cylinders 1 and 2 and the crank pulley would be out in the right fender well, and you would have no room for suspension or a wheel.

In a certain special circumstances, a V8 will fit as well, but not a Toyota V8. A V8 is about 4 cylinders long (slightly longer due to cylinder staggering), but if you find a short enough V8, it will fit the MR2 chassis with minimal cutting or clearancing. http://www.MV8R.com is a site where he put a V8 into a 1991 MR2 which is the same as a 1993. He also has a 1993 MR2 Turbo.
