2001 gt or gtp?

[justav6]

hi all. i need some help. i have decided on buying a 2001 grand prix within 2 weeks, and i need some final advice.i want either a gt or gtp, but i need the info on them. is one more reliable than the other? how much faster is the gtp? how much better is the gt on gas milage? i expect i will hear from advocates of both, and thats what i hope for.any links or info would be greatly appreciated. its narrowed down to the two, but i want to research before i decide.

Ok, here goes. It depends on what you are looking for in this car. Both are reliable although the 3.8 non-sc has had some problems with the upper and lower intake gaskets that don't affect the supercharged version in the GTP. If you want a car strictly for performance then the GTP is the way to go. It will provide more acceleration both from a standing start and when passing than the non-sc version. It will however eat more gasoline if you keep your foot in the supercharger. Of course for all that power it is worth the decrease in mileage especially if you are just playing around. (I can get 29 mpg in highway driving if I use the supercharger sparingly.)

Reliability wise both versions are reliable other than what is mentioned above. They are almost identical cosmetically so you really can't tell unless you look at the logo on the side and back which you are driving. The GTP's will often have a HUD that the GT's don't have but you can probably find a GT equipped with one.

There are many positives and negatives to both but from a performance standpoint the GTP takes it hands down.

I hope this will help you make your decision.

The GTP hands down. Not knocking the GT but if you decide to get one instead of the GTP you will regret the decision later. Most GTPs come loaded including the HUD, digital climate control system, better DIC and sound system (Bose).

Plus the GTP has the heavy duty version of the 4T65E tranny, a two speed fuel pump, better axle shafts, better intake system (supercharger over the plastic upper intake manifold), bigger 70mm throttle body, and heavy duty cylinder heads.

Plus if you decide to mod it, it will be easier and cheaper to go faster.

Fuel economy between the 2 is debateable. Like GTPDad I've gotten 28 mpg highway. The GTP final drive gearing ratio is 2.93:1 versus the GT 3.29:1.

now i want to get rid of my gt....hangs his head and walks away.

[jimmyv-21]

i have the gt and i like it. i have driven both and bnaylor and gtp dad are right- the gtp has more pep and get-up-and-go. it will depend on the price and what you will be doing with the car, but if you can afford it, go with the gtp. i can afford the gas, but not the 12 tickets in the last 2 years. either way the 01 is a great year and you will enjoy the car. i put a few hundred in mine and get better gas and 30-40 more horses, but it would cost me a fortune to put the s/c in, so you may want to get one that already has it in.

I have a GT that has every option Bob listed except the Bose system, it gets over 32 mpg on the highway, 22 in the city, and runs on 87 octane. I decided on the GT because of this fact, plus the less complex engine means less to break. I love my GT, but I would never badmouth a GTP. For someone wanting a toy to embarass stock Mustangs with, the GTP is the way to go. It all comes down to what you want. Either car will make you a nice ride.

IMO both are good cars. But not to get off track, I like my Regal GS better. Plus it's consistent with my age group - old fart and it's a perfect sleeper. I don't have to worry about everybody and their brother trying to take me on at a stoplight. BTW - I've got a 3.4 SC pulley ready to install once the extended warranty expires in a few months.

Get a GT, then use the money saved on the purchase (gtp vs. gt) and buy a turbo kit. Then you'll be faster then most GTP's

[justav6]

i thank you all for the help. i dont need to embarass any more mustangs as my current daily driver is a heavily beefed up 87 buick grand national. i do like forced induction 231 v6's because of the gn, but i realized the hard way that squeezing a few hundred extra horses will compramise reliability and gas milage.they sure are balls out little motors though. ( : i really dont need another 11 second car, but i need something that won't feel like a dog by comparison. i am leaning toward the gtp, but im getting confused about gas. can anyone tell me the differance in gas milage? also im confused about the octane requirements. ( sorry to anyone with knowlage of the grand national powerplant) my 3.8 231 v6 grand national makes about 15psi stock, and handles that on regular octane. it safely and easily handles 22psi as its set up now on premium gas. i understand that it is intercooled, but 22 psi is a big jump over a stock gtp. does the gtp really need premium, or is it suggested? how hard/expensive is it to put an intercooler on a gtp? will it knock with mid grade fuel? does anyone know quarter mile times for either? you have pushed me further towards the gtp, but i want to be sure i wont regret my decision. this may be a tough question to answer, but is there a difference in insurance rates between the two? i thank you all for your help, and hopefully i will be joining the grand prix club soon.

Seeing that I have had all three GP's (GT, GTP and the GTX(which I just sold), Go with GTP. The HP is easy to get and it doesn't cost too much. Normally I would do what Ripn said, but a friend of mine just added a turbo to his GT. He spends more time with the hood up, or in the shop then he does driving it. But when it's going, it sure moves out well.
By the way, I listed my GTX on line with Auto Trader. It sold in 10 mins.
Good luck.

How about a Twin Turbo? The ZZP/Stattama Grand Prix project car did great this year. They took out a Dodge Viper in the process. The streaming video of the drag race is at the bottom of the page.

BTW - Sorry you sold your GTX. Are you sure she/he can handle it?

Bob, that video is awesome, maybe you should send it in a PM to your new "friend". 9.73, through the front wheels and smokes a Viper by 6 cars before half track, close to 10 cars at the finish. Milan is just a couple hours from here, so that was awesome.

Yeah! I was equally impressed. Plus GT owners should feel good about it. The project car was a GT if I'm not mistaking. Of course there were extensive mods including the roll cage and a price tag to go along with it. Nonetheless, a great feat and job well done!

Yes. It needs premium as specified by GM. Some us us have gotten away with running mid-grade but it's not a good idea to put the pedal to the metal or run an undersized supercharger pulley. I have run Autotap on my Regal GS running mid-grade and I have noted knock retard (KR) at WOT above that of running premium. I only use premium in my GTP. With the cost of gas dropping I now only use premium in my Regal GS too.

A ZZP Stage II intercooler costs around $1100 and it is the most significant mod you can do to the Eaton M90 Gen3 supercharger. It can be done DIY to save on labor costs over a weekends worth of work. KR will be minimal or nil and you can run SC undersize pulleys of less than 3.0 safely. To go with that exhaust and intake mods should be used like a CAI/FWI, headers, 2.5 - 3.0 exhaust plumbing, hi-flow CAT, etc. Also a re-programmed PCM like a DHP or Intense.

This is a ball park figure for a stock '97 - '03 GTP: 0 - 60 mph in 6.8 secs. 1/4 around 15.0 secs.

The insurance will be higher for a GTP versus GT.

I hope you make the right decision and welcome as a fellow Grand Prix owner.
