Damn way to bring back an old thread haha. Yeah, i got the Kb a loooong time ago. Now im thinking of going with a built motor and kb 2.2. BTW I want a bit more power, but not sure about getting a 10psi pulley. Could you notice anything at all that sounded like something going wrong? I wanted to go Longtube headers and maybe the 10psi pulley. I could always run a gallon or so of race gas, or maybe octane booster.
