bbk 80 mm tb?
and i had a stock tb ported to 75mm and it was a decent improvement for the price. for $75 i'd say it's worth it. just make sure it's the right size tb cam for a 98/99 or you're gonna have to mod your throttle cable to make it work.
You are better off spending the $75 on getting your existing t.b. ported instead..
