who makes performance upgrades for the 95 GTP with the 3.4 dohc engine?

Asked by Sep 02, 2007 at 03:26 PM about the 1995 Pontiac Grand Prix 2 Dr GTP Coupe

Question type: Car Customization

i want to supercharge this engine and change from the weak 4spd auto to a 5 spd or an upgraded auto trans.
i understand that the 3.4 dohc motor is a pain to work on and expensive to maintain, but the only other option for me is to swap out the motor to a supercharged 3.8.
There seems to be no aftermarket support for the 3.4 motor.
my GTP has only 54000 miles so the engine should still be in fairly good shape.
Anyone who can steer me in the right direction, I would appreciate it very much.

JET makes a chip for it, APC makes an intake for it and MAGNAFLOW makes a nice high flow cat for it. Hope that helps.

I would say to just do the 3.8 swap... You can still get some support on the aftermarket... Do you still even have the car?
