my car has done 100k and i know your not supposed to run a chip and high boost etc with "old" engines so where can i get some new performance pistons from also where can i get my head ported and polished etc. "cheap" but not somewhere that will do a crappy job thankyou lwnicklin

well cheap head work and quality dont really match im afraid.oldschool on the forum is a respected member and arc will testify to his head work(and on cylinder heads
if your going down this route you might want to speak to old school as its not as simple as dropping in the pistons and while the engine is split its worth doing other stuff as well(im assuming its a gt)

maybe members from your neck off the woods will have local guys
