Don't use the Perrin / Turbolife. I have the Perrin, and while it's nice and has amazingly short intercooler piping, removing the crash bar IS stupid. I bought mine with it, but if I didn't, I'd run something else. It is a bit oversized as well, but that causes no issue. A quality core is a quality core, As long as the core doesn't leak, it will always be better than the tiny book sized unit we have stock, that heat soaks horribly. Keep the crash bar. Maybe look at that Altered Customs kit. People love paying $$$ for brand names, but is it worth it ?
