2000 Pontiac Grand Prix GTP from North America - Comments

Air conditioner did not work when I bought the car. Tried to refill freon and compressor would not take freon charge. Need to take in to mechanic.

Back right strut is going out. Makes grinding noise in fast left turns.

This is the best car I have owned. Completely reliable.

Exceptionally fast for a family sedan. I am 25 and single and looked at Camaros, Trans Ams and many other sport cars of all years. This GTP has just as good handling and for the money and gas and insurance is a much better deal. This car drives like a dream.

I have smoked all Civics, an Iroc-Z that was modified, an Ininity Q-45, and a Mitsubishi 3000. Other than the plastic knobs on the interior, I like my $13,000 GTP better than my friends $50,000 Q-45.

With less than $1000, I can get the GTP well over 300 horses. New intake $100. Smaller super charger pulley $40. New exhaust$500. A tranny cooler for the added horses $85. I have friends that have pumped thousands into their little Honda Civics and other little 4 and 6 cylinders and still can't beat my stock GTP. So far all I have done is put in a K&N air filter.

This car is cheap for parts and easy to work on. For the price range it is the best car out there. I looked and researched hundreds of cars for months before finally deciding on the GTP. All my friends love it and it really catches the eyes of the girls.

Plenty of extras. I have the sunroof, heated seat, leather interior, Bose sound system that sounds incredible, HUD heads up display, and a performance shift button that keeps the RPM's almost to the redline before shifting. You can turn this on and off to save gas as you wish.

I drove from Oklahoma City to Dallas for a NASCAR race with 4 big guys. We had plenty of room and we were all very comfortable the entire way therand back. Everyone at the NASCAR race loved my GTP and I got plenty of compliments with my new alloy wheels that match the blue/black metallic paint job (stock paint) beautifully.

I have a 2000 supercharged gtp too. it's my dads car, but I'm the one that drives it. it's a sweet car, fast, and the stereo system is exceptionally good for a stock system. How much did all of the stuff you put into that to make it faster cost though, because I'm looking to try and put it over 300 hp myself.

Sorry for the delay in replying. Since my last review I have modded a little and ran a 13.8 at the track at I think 97 mph.

The first and best thing to do is change to a 3.4 inch super charger pulley. Before doing this you need to change the t-stat to a 180 degree stat. Also you need to change to colder spark plugs. 2 degrees cooler should be sufficient. This keeps the engine cooler and reduces knock that robs HP. Plugs were $2 each, T-stat was $10. You might as well do plug wires while your at it.

Also, before doing this I would suggest some exhaust work. For $100 I had the down pipe increased to 3 inches. The stock is very restrictive. Also, GM put a U-bend in the exhaust to protect the sensor. This is the most restrictive thing in the exhaust and you do not need it to protect the sensor. I had the resonator, U-bend and D-pipe all fixed for $100 at a local exhaust shop. This helps reduce knock and improves HP. The rest of the exhaust including mufflers aren't that restrictive till trying to get over about 320HP.

Next I made a custom fender well intake with a K&N cone filter out of ABS tubing from Lowe's. Total cost was $60. I also ported and polished my throttle body which was free and increased throttle response and very easy. Also get a TB spacer for $10. This gets the throttle body of the super charger and reduces heat.

With all this and a new racing computer you should be able to dip into the high 13's.

Next I would suggest an air/fuel control module that allows you to control your air fuel mixture. With the intake and exhaust you are running a little lean. Calibrating this perfectly can increase up to 30HP. No you should be in the mid 13's and you haven't even touched the engine yet.

The most expensive is the new computer at $200 used. I think I did everything for under $500.

I have a friend that did all this and then put in new rockers and ported the super charger and he can smoke WS6 Trans Ams and is in the mid 12's.
