Yes, the Tech 4 is a 2.5L 4 banger that was used in damn near every GM car of the 80's to mid 90's including Camaros. Juice will not give me the smooth, controllable, always available power I need for drifting. Header and exhaust I know will be first. Looking at the stock cast piece I am sure the upgrade will be good for 10-12hp but that won't be enough. I believe it is throttle body injected and has an older carbarator style air intake/filter. Is there a better air intake avalible for this set up like Hondas etc? Did this engine ever come as multi-point injection? Any help would be greatly appreciated.
