1993 Toyota Supra RZ – Daily Driven – 157

Hi Avinesh, the Supra sounds fairly serious, give us a rundown.
It’s a 1993 Toyota Supra RZ factory twin turbo. It was originally an auto but we converted it to manual using an R154 5-speed gearbox from a turbo 1JZ Chaser. The box has since been strengthened by NS Spec Motorsports.
What has been modified engine-wise?
The engine is internally stock but the car is running quite a few bolt-ons. We have gone to a single turbo setup using a Master Power T70, plus all the usuals intercooler, piping and boost controller. The intake manifold has been hand made by NS Spec and the fuel system uses 850cc Sard injectors, a Sard regulator and a Bosch 044 pump. Other than that there are HKS and GReddy bits all over the place, and it’s all tuned using a Haltech E11 C2 ECU.
We hear it’s running a bit of power, is it still fairly easy to drive?
Yeah, it’s not bad. It made 426 kilowatts at the wheels on 23.6psi boost, but since then I have detuned it to about 400kW at the wheels for street. Even that is still a bit much.
What about the rest of the car?
The exterior is still a work in progress. I have an aftermarket front bumper with Do-Luck side skirts and rear bumper caps. The 18-inch rims are 8.5 inches wide up front and 9.5 inches wide at the back. But I wish they were wider.
The 2JZ is regarded as one the best engines ever made, do you rate it highly?
Definitely! My motor has been running strong ever since we got the car done. Four hundred kilowatts on pump gas with stock internals is very impressive in my book.
Have there been many headaches with the build?
Yeah, there have been a few but none to do with the engine. I had to replace the driveshaft with a single-piece billet one for strength. Basically, the original auto driveshaft couldn’t really handle the power.
With hindsight, if you could do anything differently, what would it be?
I would have got a 6-speed Getrag box instead, and I probably wouldn’t have bothered with the bodykit, as it needs a lot of maintenance.
If you didn’t own a Supra, what do you think you would be driving instead?
Most probably a Skyline GT-R; I have a lot of respect for them.
That’s what most Supra owners tend to say.
