I am looking at purchasing a 1984 Celica supra with a 6MGE swap(3.0L, 5 angle valve job, milled head). I was going to drive it stock this winter then add more power via ebay t3(turbo) @5-6 psi. I can't find a proper exhaust manifold. I know about mid range honda engines(b18, b20) so this a bit of a jump for me. Any suggestions?
