ya i've been thru that forum, but it's seems that no-one can give me info that i want, this is one of those things that's an investment...so i want to do it right, i dont want to get just a small fast spooling turbo, and then be limited, but i dont want to get a big turbo and not have is spool fast enough for what i want, then i dont know do i want air or oil cooled???? these questions are driving me crazy, cause i've been ready to this for a while and now i'm stuck. on top of that i dont want to just ask one person and go with that, i want a bunch of suggestion to pick thru.....if any of that makes sense
