i have a 94 GSR and im bout to put a turbo kit in her, i have a few questions first...

im lookin to get about 270hp maybe 290 out of her with stock internals, is this possible? and if so what is the best way to go about tuning my GSR with 7psi and about 270-290hp?
C/R is 10.1 so i need to retard the timing 1.25 degrees/#? cam or ignition timing?

the reason im asking to because im doing reseach before i just jump right into it, that way im prepared.
other info:
Garrett T3/T4 pushing 7psi
12:1 FMU

sorry bout all the questions, never tuned a turbo b4 so...haha

thanks for you help
