So i have a t78 right now and was thinking of going to the gt42r. I know the 42 has a V band clamp, but what other things would i need to replace? The manifold and wastegate should work??

Also there are different A/R versions of the 42r. Im guessing that for max HP, i would want to have the largest A/R??

Thanks,
Eric

 

just turn up the boost on your car

 

lol that should work.

 

agreed, just turn that t78 up to 2 bar

 

I just want to stick to 93 pump. I know if i turn my turbo to 30psi, i should be around 600rwp; but the 42r at the same 20psi would make another 50rwp.

 

Alcohol injection then if you want to run 93pump and 28ish psi. Get a nice methanol kit and spray an assload.

 

Look at his sig, he's already running alc/water.
