i have an 83 celica supra that i just bought, it has the classic leaky valve seal problem, it has 100,000 original miles on it and i was planning on redoing the whole head, port polish, aggressive cams, big valves, adjustable cam gears, polishing the intake manifold too. i am planning on an 11 pound flywheel, aluminum driveshaft, short shift kit, bad ass springs with a rate of around 350-400 pounds, polyurethane bushings all the way around. basically i need help finding web sites that carry these parts, do you guys have any suggestions or brands that you trust? who stocks cams and valves for these engines, 5mge. where can i find lowering springs that'll lower it only about 1" on all four corners that are pretty high quality? my goal is to basically break the 200 horsepower mark lol cuz i've heard these engines have gobs of power to be unlocked. any help or suggestions would be great, cuz i dont wanna go into this project blind, any combos you guys are running that work well for you?
