build up a 3.1 or drop in a 3400! its less work then putting in the 3.1 turbo

Wurd!
what about putting in a gtp engine
3.1L Turbo engines are from te early 90s (Can't recall the exact year) GTPs, and the 3800 SC's are from the newer third-gen GTPs.

The 3400 SFI would be much easier than doing either of those.
3.1 turbo 89-90 gran prix only 3800s/c comes in gran prix and bonneville ssei 92-03 w/diff. hp ratings 205-240
Ive heard that those types of engines have a faulty Head Gasket. I no that i have already put one in my cavi, and my sister put one in her 2000 Z24. I guess that all J-Bodys have some engine trouble.
