I've had my L67 TB off for a while because I wanted to hook up my charcoal canister. And the only way to make that work was with the original 95 TB because it has 2 vac ports on the side.
On the 99 L67 TB, I port matched the exit to the L36 UIM and grinded down the MAF hump. But I never did much more than that.
I've been messing with it a little bit at a time and heres where I'm at now:
-Filling in the coolant ports w/ epoxy
-Filling in a couple spots in the TB where I broke through (bolt holes etc.)
-Smoothing out the change in bore from the MAF area to the TB plate area
-Cleaning up the MAF screen area
-Filling in the area before the MAF
-Cutting the TB post
-Adding another port of the evap system
---still gotta cut it down and grind it leaving a lip similar to the original
-Once I'm finished smoothing it all out everything will be polished
So whatcha think?
Heres how my car is sitting right now: :(
Had to take it apart so I could give the rotors to a friend so he can spin em.
