Thread: L67 swap into a 99gt

Top swaps are ghey! Motor swap FTW haha.

Here's a writeup a friend Marc and I made on swapping the entire L67 motor into a L36 powered car. Dropping the cradle in my mind would make your job harder. Just pick up a hoist.. That being said, computer will require tuning, stock L36 fuel pump will be fine, and stock wiring is fine. Don't let anyone tell you otherwise. Anyhow, here's the link to the writeup
L67/L32 Motor Swap (W-body) - Complete Guide

top swap FTW. Its reliable, no matter what anyone says. I constantly beat on my car. Im still on a stock pulley, and beat up 3.4 L67 setups

not sure, im using an intense pcm, when dave @ 3ep looked at it, he said the timing is really conservative. The car really needs a dyno tune. If you know what your doing and have all the supporting mods a m90'd L36/26 is just as reliable. To pop a piston or spin a bearing is from someone doing something wrong.

Im only on 5psi, 8 if its below 26*, i get very little knock even in 18* weather. Most i had so far was 1.6* of knock in the top of 2nd gear
