HP goals for turbo build is 550ish and no more then 10psi. 14 psi will be availible but ill stick to just the 10psi spring until i get the tune right.
now for the turbo build items, ive got pretty much everything except the cam kit, base tune, and hp tuners in my garage. I can at least get it on and set up to run before i do the cam and meth kit.
