Ok, so, I have been in the market for a GTP again lately, and came across what looks like a deal and wanted to sort of get your opinions on it..guy has a 99 grand prix GT, that has been top swapped, has 42.5LB injectors, intense racing S2X cam, 105LB valve springs, ZZP modded retainers and valve stem seals, Ported supercharger with modular pulley system and snout turned down for small pulleys, gasket match port and the heads and intake manifold, rollmaster double roller timing chain, and a set of ebay cheapo headers....also had HIDs and small stuff like that...
My question is..he said it hasnt run right since, you can drive it, but its never had a tune, and he has a GTP computer in it right now...do you think it just needs tuning work? I would guess it would pretty much have to get a tune to be at all driveable, without having alot of troubles, at least when you went into boost...I can get it for like $2800...and he said theres less than 15 miles on it since the rebuild he just lost interested, lost money and cant tune himself...I have someone who can tune for me...sounds like a great deal considering what engine work has gone into it...even if I had to tear it down and rebuild it all because of an overlooked bottom end problem or something it sounds decent. Just wanted to gauge opinions...I dont know anything on how the top swapped GTs run or anything as far as if theyre harder to get the tune down or what...any info into this would be appreciated. Thanks!
