Yes, I agree. My point is more about searching, seeing what other members have done, and making a good estimate out of that. Now aren't the members supposed to make some effort by doing some research? I mean, there is a reason for having a search button, right?
Anyways. If you want BIG hp, look up comments of other forum members on what they have, how much hp they're making. That should give you a ballpark idea.
Also, refer to
http://www.sr20deforum.com and look up the sticky post in the turbo section. That should tell you what you need to make the kind of hp that you may be looking for.
