Thinking of Adding Propane Injection and Bigger Turbo over winter, help needed.

Ok here are my basic mods, the small list.

AGP Garrett Turbo Kit
AGP FMIC Kit
255lph Pump
850cc injectors
AFPR
DSMlink V2
Wideband o2
6 bolt - 2g piston/1g rod
Hks 272's
Fidanza Cam Gears
SS Valves
Crower Valvetrain
etc

I have my rev limiter set to 8500rpms, but shift at 8k. So basically Im looking for a turbo that will hopefully spool around 4k or so and make alot of power to 8k. I am currently running a 50trim .48ar, 23psi on 91 octane with virtually no knock.
I want to add propane so taht hopefully I can get at least upper 20's for PSI on 91 octane.

I have also grown out of the 50trim, it jsut doesnt make enough power for me.

Any suggestions for a new turbo would be great, this is a almost daily driven car also.

look for a 56trim.

hmm, What do you guys think about getting a .63 or .82 AR for my 50 trim, could I make more power with that?

I believe you would make more power with the .63 and your spool time should not change very much. It should move your power band up around where you want it.

What about the FP30 series turbos? The FP 3052 should spool around 4k if not earlier and its capable of putting down alot of power.
