Okay due to my recent sponsorship. I have been talking to the owner of the company pretty frequently and we have been discussing the goals that I have. He could honestly care less about looks, his main concern is the performance aspect of my car. (Though I plan on refurbishing the Z's looks a little)...

We were discussing what sort of HP we were planning on going. I was tossing around the idea of 500rwhp and during the convo he mentioned he is coming out with new stage 3 BB turbos he is looking for someone to try out. Capable of well over 650+... My question is... Is how driveable is 650hp?

To do this, I would have to get some internal work.. Although I will get a pretty damn good deal on everything due to the sponsorship, it would still cost more.

What would you do? Be happy with 500 (I am shooting for 550rwhp) or go ahead and splurge and get the 650ish (Only live once right?)....

I think im leaning more towards the 550 personally.
