Supercharger for the GT Engine and L67 in the GT and SE.

[GTP Dad]

It appears that a lot of forum members want to know if the L67 from a GTP will fit or can be adapted to the GT or SE. Many of you also want to know if the supercharger from a GTP can be placed on the non-supercharged 3.8. The answer to the question of whether an L67 will fit is yes. But you must change the PCM, fuel pump, and will need to put the 4t65e transmission along with a host of other parts to make it work.

As far as putting the supercharger on the non-supercharged engine, it is possible but you need to use the heads, lower intake, PCM and harmonic balancer from the supercharged engine to make it work. You should also change the fuel pump and will need the heavier transmission (4t65e) to handle the power.

I hope this answers the question for those who want to know!
