Yea the GSR motor is a really good platform to build upon. Whether you want to go forced induction or all motor, I think you'll be happy.

As far as turbo's go, you can run about 8 to 9psi until your rods go out. Anything more, will need some internal mods. Like a Drag3 kit will produce around 250whp. I'm sure some of the other guys on the board can help you a bit more.....


Good luck!
