haha i noticed the 5 lug pattern too.. just figured they were different rims.. never seen you post a 5 lug conversion Shingo! guess i was right

 

Phew... I was trippin out there.

What are those? Volks? How heavy are they?

I kinda dig those wheels, but I don't think they'd look too good on my white GS-R. But I really dig how the spokes of the wheel "dig" into the rim.

Though, I think I may end up going with O.Z. Chrono Evolutions, but those wheels you have might be an alternative. How much did those cost?

But... (And sorry gsrracer to jack your thread) I'm worried about performance losses. That's why I'm looking at the Chrono evos... they weigh about 3 lbs less than my current wheels. You think that would offset the unsprung weight problem of shifting from a 15->17?

 

If your going to get a jrsc. Whats the best size header and exhaust combo? I keep reading a header with a 2.5 inch collecter and 2.5 inch exhaust is the best. I am thinking about buying a jrsc and getting either a jdm or kamakaze header. I head the kamaz header is the best performing header, but the quality is not there at all. 4-1 is the best for jrsc due do the jrsc making nice bottom end right?? Whats a nice exhaust for the jrsc

 

JRSC is harder on the engine than a good turbo, not easier.

 

Get it done right. Figure out exactly what you want in terms of a powerband and buy parts accordingly ie. exhaust, internals, etc... then take it to a dyno and program your computer to match. I've heard this takes time and money, both of which you have. What you really should do is read up on it until you're an expert, because IMHO, there's nothing dumber than someone with a tricked out car which he bought off the shelf, and has no clue as to how it works. What's the point? You could have bought a "real" fast car with the money.

 

which sounds easier to you constant boost or boost above certain rpm that you wouldnt usually cross everyday.
