everyone seems to be repeating the same thing, never buy another mans project. that could be valuable advice in a lot of cases, dont get me wrong. ive had a lot of different cars, the last four have been integras, none of which were boosted, but i know quite a few that have boosted tegs. the gsr from what i hear has much stronger internals and will take 6 or 7 pounds without a problem. obviously give your thorough inspection, but i think the best advice i can give would be to first ask him why hes selling. i find people squirm a lil bit when they have crual intentions of dumping a p.o.s. into someone elses lap. if he has a preggo girlfriend an need a van instead, that could be a great opportunity to pick up where someone else left off on a strong project...
