Does anyone make a turbo manifold that fits a t3/t4 on the Turbo II? If they do what wastegate flange do they use?

 

T4/T3 is too small for a 13B unless you can get one of the Garrett Japan/HKS Japan only AR 1.15 or above T3 housings. The blade is just too damn small for rotaries and piston engines larger than 2.5 liters. Now if you were to go twin T4/T3 then you would be able to make some good power. Twin T04E 57t/T3 Stage II AR.86 with a racing wastegate would be a sweet combo. Even as a bolt on replacement for a TII the T4/T3's exhaust side would choke the engine to hell and back. For a TII with very little mods, a free flowing exhaust, 850cc secondaries and a reprogrammed ECU a T04B or E with an AR.84 T4 Housing and an O-trim wheel would be a good match.

 

the factory turbo's are pretty much t3/t4's from the factory, they cannot support the exhuast flow required for a fire breathing 13B
