How much could anyone help if I asked this question?
"I need to buy a house what should I get?"
It would take a book to answer that question. You need to give us a budget, what hp goals you are looking for. Take some more time and keep looking... it might not pop right out at you but you'll learn a bit more about what turbo options are out there and give you a better idea of what's possible. Just so you don't ask the question, "I want 450whp for $1000 on a T25."
Also check out the turbo section at www.sr20deforums.com. If it's an option for turboing the SR20 it's been done to death over there.
This is a BAD THREAD guys. I'm not interested in locking threads where someone is asking for info, but this horse is so dead it smells. As previoiusly suggested, do some research. The truth is out there.
Anyway, if you have some specific questions, please start a new thread, but this one has been answered at least twice in this forum and probably two or three times on AF as well as the SE-R Mailing List and the SR20DE Forum.
