Thanx bro, the tires are brand new but i'll check the bearings and brakes, good suggestions plus it might be the problem since other people said the same thing.
the headers are 190.00 from pacesetter, those are for the black ones, the ceramic coated ones are 300.00 at nopionline.com, thats the only company that makes as far as i knoe, been doin some research. How much performance do u think i'll get out of porting the head and increasing the compression ratio to 10:1 or 11:1 or somethin, n e pistons n e where like that? i'm goin N/A with this one, want to buy a turbo charged one later

Who makes good cams, n e thing else i should change sidez the head gasket(not broken) and where can i find that carbon fibre hood they used to have for it that looked like the TRD 3000gt, not on supras.com no more
