Here is the set up I am working on.

B16A
9:1 CP pistons
Eagle Rods
CTR cams - Rocket Valvetrain
Edelbrock Victor X
RC 750cc

I currently have a T3/T4 60 trim .82 a/r. I wan't to make 450whp - 500 whp on 93 octane. Do you think this turbo can do it or should I upgrade to something like a T3/T67?

 

upgrade to a gt30 or something like that. You'll easily make your power, and since its ball bearing, it should spool up a little bit quicker.

 

81mm B16 its going to be hard to make 450-500whp on 93 octane. The turbo will support the power.

 

Thats definetly a no if you want that power on pump gas. The turbo will support it, but at pretty high boost.

I'd say a GT35R. The spool with the T3/67 is going to suck with a stock bore B16.

Or you could just keep that turbo, shoot for less power on the street, and tune higher boost on race gas. that power level is going to be useless on the street anyways.

 

Well the only time the car sees the street is when driving to the track. I live in bumblefuck Idaho so the ebst we have is 93 octane. Boise has E85 but thats on the other part of the state.

I already have to drive 1.5 hours just to go to the track.
