Ok so you took a V8 to a V6 thats different. What year is the 3.8L from and is it the 2001 and newer 3.8L with the supercharger?

 

The car had an L98, because I specifically wanted a car with rear discs and posi. The 3.8 Buick is one from the good old days (out of an 87 Grand National) when they made enormous power with a turbo and intercooler. Those new 3.8s aren't really worthy of swapping for a V8, just my opinion of course.

 

O so you have the turbo 3.8. Thats a good motor made nearly 400tq and like 280hp.
