- Downpipe/piping

The turbo kit came off his fully built gsr made 450hp on 15 lbs

My question is should i run a bigger/or smaller turbo? my gsr is stock internals, so would this still be a good setup? i believe i need smaller injectors.

BTW: my goal is to have 300+hp
The injectors are fine, they are a little big and are good for around 600 hp to the ground but the honda ecu controls the larger injectors fairly well. Optimally you would want some 550cc injectors for 400 hp to the wheels. The turbo will be laggy and you wont get the benefit of running high rpms or running higher boost since you are on a stock motor. 350 hp is easily attainable on your motor. You can spool up much quicker with a smaller turbo and make 350hp. I guess it just depends on how much lag you can put up with and what you are comfortable with. If you rode in his car and you are ok with the spool then keep the turbo. I wouldn't think the tune would be that far off but a quick touch up may be needed.
