Joe, do some inexpensive mods like opitmization of the TB, LIM butterflies, and of course cleaning up the UIM/LIM/head inlets.





What's up Bro??? How you been? Thanks for the advice. I'm gonna set a 3 day weekend aside in a few weeks, and go through and do all the cleaning, plus intake.

What exactly do i do with the butterflies?

Thanks,
Joe

Be careful! The butterflies are thin as hell to begin with, therefore adding a countersink to them takes some patience, but the end result makes you feel all warm inside while holding the secondaries open and not seeing screw heads/threads protruding into the air passage.

I port matched my UIM/LIM/head inlets as well....may take a couple of R&R's to get up the nerve to go all the way.

What happened with selling the car...no credible hits? Good luck in whichever road you take!
