I wanna put my 1999 grand prix supercharger on my 2006 grand prix not supercharged is it compatible
it is compatable but you will need to do a top swap. you can buy a kit at zzperformance.com i think they are fairly cheap.
check compresion ratio ,super charged engines have a lower compression ratio .
^^which is better for the L26 because with lower compression on the L67 will give you more power on the newer L26
