Try fuel injection cleaner. they could be clogged. also get new plugs and wires. make sure they are gapped right. one could be bad.
Yes, both cars had the exact same 3.8 series II engine.
It is right below the thermostat housing on the drivers side of the engine, below the throttle body.
The supercharger on a GTP is open to full at full boost bar and at that rate the normal 7.5lbs of boost increases to 10.5 at wot( wide open throttle).
Yes you can, but you will need some things Here is a list GTP Supercharger w/ bolts and pulley GTP Throttle body GTP Fuel Injectors GTP Lower Intake Manifold GTP Cylinder Heads w/ valve covers Passenger motor mount GTP Harmonic Ballencer GTP supercharger belt tensioner and idler pulleys GTP MAP sensor GTP Vacuum lines Head Gasket set Head Bolt Set Lower Intake Manifold Gasket GTP Valve Cover Gaskets Supercharger gasket and coolent O Rings Throttle Body Gasket MAP/BBV harness adaptors PCM Tune In my opinion, you would be WAY better off just buying an L67 engine. I have seen those on craigslist from $200 to $500. Ya it will be a little bit more frustrating, but so will putting and replacing parts from a gtp onto your gt. But good luck though :)
Guaninosine triphosphate.
Yes
Its causes gear shifts at high throttle at 5800 rpms instead of at 3800 - 4400 as stock computer will do in GTP
Guaranteed Technical Particulars
it is black and right be side the throttle body with a 4 wire plug in the top of it with a metal bracked surrounding it
the GTP model has the supercharged engine in it
The GTP is supercharged and the the GT is just the 3800 engine without a supercharger
An engine compression test on a 99 Grand Prix GTP can cost $180
