Thing is do you actually think the zed will be better with a supercharger? How do you know that, definitively? It's a lot of money, hassle and tweaking to add power to a base model that doesn't need it. I have both a DE 350 and 370 Nismo and TBH I think the lower BHP/Ton ratio of the 350 works better on the road. Even with much improved handling on the Nismo it's still difficult to drive over eight tenths, so think carefully before winding a 350z up to 400bhp. Patronising post over!
