GM L82 3.1L V6
3.4, and 3.8.
The 194 3.1 only
Yes
yes it will fit
No, they are 2 totally different bodystyles
No, the compressors and mounting points are different on the 95 Lumina
Yes
No, there is no information suggests that a 1996 Buick Century 231 will fit into a 1999 Chevy Lumina.
No, Chevy Lumina Z34 ever came with a 3.7L engine. So probably not.....
If they are both 3100 engines...yes. Direct swap. The only thing you MAY have to change would be the motor mounts.
Yes it will, I did the interchange on mine
The 99 Buick Century 231 engine will fit into a 96 Chevy lumina with a little fabrication.
