Forced Induction Finished Builds
370z Forced Induction for Noobs...
Here's some good reading to get you started.
The other thing to think about is how much power you really are comfortable with. With full bolt ons and a tune, 330 whp is still a lot of go, especially if you get the suspension dialed in and can drive. It's not a number you'll brag about, but it's not slow at all. Swap out the rear end gear, and you've got a very quick car. 450+whp is a whole different animal. It will require serious respect. If you mat the throttle when you shouldn't, it'll throw you off the road backwards. It's a lot of fun, but you've got to be paying attention at all times. And some of the compromises you'll make for the power will make the car suck as a commuter. The clutch you'll need will be a pain in traffic, for one. It's all a trade-off.
