Yeah I know. I chose the turbo because I think it's sized properly for our car. By the time you come close to 400 you need to build the motor. Why would you choose a 550+ hp turbo like the 5757? You need to do some more research. I chose the small a/r (.48) for good spool. I'm hoping to be 325-350whp with aux fuel.
Sorry off topic.. If you want to continue this please PM me or go on my build thread. The x37 fan boys might get upset
