This forum does rock and when it does become negative its more like constructive feedback. The 350Z forum however has become overwhelmed with a bunch of a$$holes.
If you want Maserati speed you only need a supercharger and even then you will have much more fun in your 370 as you will be able to punish Maseratties.
And dont chose your kit on the way it sounds (bov), choose it on the way it feels. Superchargers are going to be linear power and a turbo is going to give you a shot of torque that will slam you around 3K. Some people like linearity and some like the sudden onset of power. Either will put a huge smile on your face!
And the best advice you can get is do it right the first time. If you cant afford to do it right you will regret it.
