Grannas Racing now offers Precision Turbo kits for the MKIV Supra. These are available with the full lineup of Precision Turbo & Engine turbochargers. Featuring a 304 stainless steel exhaust manifold, turbo in any configuration of your choice, downpipe, midpipe, oil feed line, oil drain line, and wastegate dump tube(s). FIVE different manifold types are available: T4 divided, T4 open, Vband inlet, T5/T6, and PROMOD inlet. These go all the way from 62mm up to the same 102mm turbo that we run on our 6-second world record, IRS, h-pattern stick shift "ORANGE MAN BAD" Supra.
These kits are specifically made for the 2JZ-GTE MKIV supra but can fit other chassis with the GTE motor, just ask about fitment in your chassis! I also make these for the GE head as well. And if your wondering about fitment on a RHD car, check out the pictures of the RHD supra turbo kit fitment.
The available wastegate configurations are as follows:
The 44mm (or 46mm) gate flanges are compatible with TiAL, Precision, and TurboSmart wastegates. We do not do any configurations other than those at this time unless you are looking to do something custom, which is possible but would require longer wait time, and may require you to provide a turbocharger if need be.
Each turbo kit contains:
Grannas Racing exhaust / turbo manifolds are built for maximum power, reliability and strength. These manifolds for the 2JZ engine feature 1.25" diameter primary tubes, a fabricated 6-1 collector and stainless turbine flange. These manifolds are proven for excellent wastegate priority and we know you will be happy with them being able to control boost without issues. We run this same style manifold on "Orange Man Bad" which runs 6 seconds in the quarter mile.
These manifolds are crafted with Schedule 10 stainless (304) and we run the smaller primaries as we have seen no major benefit to the 1.5" primaries. For example, we run the same primary size on our 2000+HP race program without any issue. I also do not do 321 as there is really no major benefit to offset the added costs.
We use a mild steel head flange as the stainless flanges tend to warp badly, and that is a major issue you want to avoid.
The downpipe and midpipe are both heavy wall 304 stainless steel with an o2 sensor bung in the downpipe.
