How much Horsepower do you gain from a streetport, on a 1990 TII?

After you streetport your engine what kind of other mods will you need to support the extra power? or do u even need anythign else?


Thanks

I tried searching but couldnt come up with anything usefull.

opening up the eugsaust and intake i guess helps the port be all it can be, as for hp gains, i dont know

A street port has been known to add up to 20% horsepower on an N/a i believe... but for exact numbers, i'm not sure

40 Fwhp. Addition of an intake and an exhaust will also help, but then you're into fuel cut, boost creep, and fuel delivery.

IMO, start with exhaust and intake, and go from there. Unless you need a rebuild right now, a street port is a not a good starting point. You do know you need to have a rebuild done when you get your engine street-ported, right?

Thats why im thinking is the streetport worth the money.
