Yes it can and will fit with very little work. I have just dropped in a 98 GTP powertrain into my 01 Aztek GT making it a Aztek GTP. This is the first I have seen anywhere and I have been researching this for six months now. Alot of talk and theories so I performed the swap myself to prove it can be done. Some mods are required like throttle linkage, using GTP Power Steering cooler, and changing the brake reservoir to clear the throttle cable, which mounts to use and other small considerations are required . It will all bolt in, use a complete donor car as it saves trying to find the right parts. I have repinned the PCM to make it work and now am finishing the rest of the wiring. They DO NOT have a direct wiring swap, and this is the major part of the work. The 3800Sc is alot tighter of a fit but with using the correct stock parts (no aftermarket) it will fit nicely but snug.
It should so long as both vehicles are each Supercharged 3800's or non-supercharged 3800's and make sure the Grand Prix has a 3.8L (3800 V6) and not a 3.1L V6 (3100)
the GTP model has the supercharged engine in it
It is best to fit a suitable supercharger to extend its working life
203 The 3800 Series II engine is rated at 205 H.P. The 3800 Series II Supercharged engine is rated at 240 H.P.
It's in your owners manual
Theoretically, you could put the supercharger setup from a factory supercharged 3800 series 2 engine but it would be a lot of work and you would have to do a lot with wiring. The Buick Park Avenue, Pontiac Bonneville SSEI and the Olds 88 LSS will have that engine.
All 1997-and-up GTP's come from the factory with a 3800 supercharged engine. For 1997-2003 it was the 3800 Series II, and 2004-and-up it is the 3800 Series III.
This question references General Motors built FWD vehicles with the 3800 Series supercharged engines. Sensors included the O2s in the exhaust manifold and the downstream of the catalytic converter pipe. knock sensors in the block, and the manifold absolute pressure sensors in the intake manifold.
In my opinion, it isn't worth purchasing a car that has 189,000 miles. I would avoid buying a sporty vehicle like a supercharged 2000 Pontiac Grand Prix GTP 3800 as a first car.
It will have supercharged writen on the engine cover. or you can see the supercharger's snout sticking out the left side of the engine cover. and the loud whine the car makes when you floor it..lol
The 3800 Pontiac engine had bolt torque specification is 160 pounds. The head bolts should be torqued in 40 pound intervals.
The 3800 engines with the superchargers require premium gas. Higher octane fuel prevents engine from self ignition of oxygen and gas causing engine misfire.
