ok guys, still pretty new to the forum so bare with me alright. i have done some searching and found some answers but not what i want to know. I was curious as to if a gst header would work on my 4g94, i found a post that says the gst header is to BIG, in what sense? and also i want to know if anybody has the specs for the exhaust port on the 1) 4g94 head 2) 4g94 head exhuast bolt pattern 3) gst header port size 4) gst header bolt pattern. From what i have seen they look like they would be a match but with out having them i hand to take some specs and figure it and not having the cash, i thought i owuld hit the forum up. So anyone with ifno, please help!!!

*note* i am looking to do a small home built turbo job for now, never had a turbo, but deing to get one!!!, looking to push 6-8 lbs of boost, nothing special, just want a LITTLE more power, for NOW. Also, how will fuel economy and stress on the egine be at 6-8 lbs, i know it can take it but realistically, how will it effect reliablilty?
