Thread: 2000 Grand Prix GTP Turbo

Turbo + GP = One bad ass FWD car.

I was the red GTP next to you at the meet for most of the morning. You got a bad ass setup there.

Since it's pressurized air before the throttle body, you can't run a simple pcv system that's metered.

I do have a pcv setup for the rear valve cover. The manifold is tapped and there is a thread in pcv valve. Can't do that for the front one though. Have to run the breather for now. Until I setup a catch can breather setup.

Went to dyno the car and had all sorts of problems. Found the PCV was blowing oil into the intake when the car was under boost causing the plugs to foul. Found a vacuum leak at the fuel pressure regulator. Car was misfiring due to the plugs fouled. Ended up taking it home with no dyno.
Still working out all the bugs. Beginning to think this car is cursed.

I want those rims.

Very nice car. Looks clean. Would live more videos and pics

Hopefully videos coming soon. I haven't had the car running long enough. Lol

Were you able to get any of the bugs worked out or figure out the rest of them?

Thanks guys!

I got some if the bugs worked out with the tune. Found a vacuum leak at the fuel pressure regulator. Still trying to get a decent street tune. Found out the plugs were fouling due to the pcv system blowing oil into the manifold under boost.

seeing this makes me really want to keep my 98 gtp and turbo it. awesome car man.

Thanks!

Found that my injectors were bad causing the car to run crappy. Now I have to find a decent set.

Didn't you just buy 80#ers?

Yes I did. Think something is wiping the injectors out.
