Also, I just thought about it, why not bore and stroke? Make the car either a 3.8 or a 3.9 (or if you're crazy, a 4.0) and THEN go for more power. Obviously the 3.8 parts are already around.

I know what you mean about having the power when you want it, but a good turbo setup doesn't have to take forever to spool. In fact, with a lightweight flywheel the turbos spool a bit quicker, and to make the 400-500whp mark, you don't need big turbos, so they'd spool even faster.

Just a thought.
