Q: i know for high boost you should have a fully built motor but what manufacturers would you recomend
A: i have eagle pistons and rods, crower springs and retainers, i forget the brand of valves i have but theyre titanium, i think theyre HKS, as long as its forged you should be all set, watch out for things that increase your compression in a turbo setup because you run the risk of detonation, also if your looking to run big boost, your gonna have to be ready to shell out a tremendous amount of money, i had my LS/Vtec fully built and it cost me over 4500 in parts and labor, make sure that you have a quality shop do the work for you if your unsure of anything at all. Make sure you get Hondata S300 or a similar program to have it tuned and you have the proper fuel supply and turbo setup. Make sure the turbo can handle that boost, odds are your gonna want a garret or HKS turbo to run high boost, not one of the kits you got on ebbay for 600 bucks
