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 available wastegate configurations are as follows:
- T4 Open with 60mm single gate
- T4 Divided (twin scroll) with twin 44mm gates
- T6 with 60mm single gate
- PTE T3 vband inlet with single 60mm gate
- PTE T4 vband inlet with single 60mm gate (smaller bolt-on center cartridge)
- PTE T4 vband inlet with single 60mm gate (“sportsman” v-band center cartridge)
- Xona/Tial vband inles with single 60mm gate
- PTE Promod inlet with single 60mm gate
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.
If you are looking for a complete turbo kit, check out our complete Turbo Kits. We are direct with Precision Turbo & Engine, Tial, Xona Rotor, and Garrett Turbo so we can get you whatever you need.
Grannas manifolds feature the following:
- 304SS heavy wall construction (schedule 10)
- M10x1.5 tapped turbine flange (on T4/T6 variants)
- Professionally TIG welded and back purged. These not only look like art/jewelry but perform at the highest level as well.
- Mild steel head flange to combat warpage
**We try to keep the common configurations above in stock, but I would recommend using the contact page to verify this before ordering**
