Possible new owner, had some questions.

I wanted some input on the 370z platform in order to make my decision a little easier. I recently sold my stage III b5 S4 and am looking for something comparable on power but with a "sportier" look, that's where the 370 comes in. I test drove one this past weekend and I surprisingly enjoyed it more than I thought I would. Everything about the car is great but it could use a little more power for my liking.

I did some research and seen that GTM has developed a TT kit. I am looking to achieve about 450whp on pump gas, my question is will the engine take it? I did some research and from what the tuners say it will take it very well however I want someone's input with experience on hand. I know it is not an apple to apple comparison but many of you probably had 350z's prior and now that it's been around 6-7 years many have tested it's limits.

So the question is... can the stock engine take the boost (6-7 psi I guess) without any problems or do the internals need to be beefed up? Again I am not looking for any crazy HP numbers just something comparable to my old car.

Thanks in advance,
Alex
