Turbo an ST (~300bhp) - 6G Celicas Forums

Topic #245 2 posts Started by 3TST
the G-head conversion is not cost effective. your better off doing a straight up turbo of your existing 7AFE and run it at 8 psi or less, or for higher boost levels reinforce the internals with 4AGZE parts, etc. I don't know exactly what needs to be done as far as internal reinforcements, but you should be okay up to 180 hp or ~ 8 psi.
