Bri-Guy-GA Posted October 25, 2005 Report Share Posted October 25, 2005 Hi, I am looking at buying a '90 Grand Prix, McLaren edition here in GA. I am moving from a '87 Conquest TSI and was wondering what differences I can expect? The Quest handles like its on rails and with the upgraded 16G tubo could run rings around most ricers. How does the TGP compare performance wise to the Quest? I have always like the Grand Prix and to find a turbo is a bonus. Quote Link to comment Share on other sites More sharing options...
Euro Posted October 25, 2005 Report Share Posted October 25, 2005 finding a turbo is a definite bonus since less than like 5,000 were made within 89-90. im not 100% certain, but your conquest will probably handle better stock, as well as perform better but those can change quickly just hit up the Turbo Grand Prix part of this board for any questions!! and get some pics up if you get it!!!

J Posted October 25, 2005 Report Share Posted October 25, 2005 welcome, i have been on the boards for years and i am soon to be a owner of a TGP (highest mileage tgp that is) :? Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted October 25, 2005 Report Share Posted October 25, 2005 Woot! Another Georgia member! Not far at all from me either! I'm in Riverdale. Quote Link to comment Share on other sites More sharing options...
Bri-Guy-GA Posted October 25, 2005 Author Report Share Posted October 25, 2005 Thanks guys. One question. In the description for the car he says that it had an exhaust leak (Y pipe I guess) and runs rough along with possibly running rich. Other than a full tune-up and oil change any other problems those symptoms can be? I already have a tempermental car and would rather find a more reliable one, in a sporty style I like.

GP1138 Posted October 25, 2005 Report Share Posted October 25, 2005 The exhaust leak might be the infamous TGP crossover leak. You'll find plenty of info on it in the TGP section of this forum. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted October 25, 2005 Report Share Posted October 25, 2005 If it has an exhaust leak, it's most likely the exhaust crossover. The stock ones are prone to cracking and leaking. Not a really major fix.. Jeff M sells far superior built ones here on the board. Quote Link to comment Share on other sites More sharing options...

mfewtrail Posted October 25, 2005 Report Share Posted October 25, 2005 That car is still for sale? From the description, it sounds like one I asked about that was located somewhere just east of Atlanta(can't remember the exact location). Is it black with about 70,000 miles on it? If it's the car I'm thinking of, it probably doesn't have too much wrong with it at that mileage. As far as performance goes, a good running stock TGP should be capable of low 15's. They handle alright for 3300-3400lb FWD cars, but the handling is nothing special. BTW, I have a black 1990 TGP and live a little ways south of Athens. I have a chip, K&N filter, and custom catback exhaust on the car and ran a 14.7 at the Atlanta Dragway last year. I should be able to knock off another tenth or two with a better launch at the track on my street tires. Our transaxles probably wouldn't like any drag radials or slicks until it's rebuilt with that in mind. Quote Link to comment Share on other sites More sharing options...

mfewtrail Posted October 26, 2005 Report Share Posted October 26, 2005 Man, Matt.. we need to race. Too bad you'll own me I'm thinking about heading up to the Atlanta Dragway Friday. I think a few other GP's might be going as well. Quote Link to comment Share on other sites More sharing options...

john99gtp Posted October 26, 2005 Report Share Posted October 26, 2005 hey matt, would this happen to be the TGP you were trying to get me to buy pics! Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted October 26, 2005 Report Share Posted October 26, 2005 hey matt, would this happen to be the TGP you were trying to get me to buy pics! Yep , I'd have to dig up the pictures of it, I think I threw them on a cd and deleted them from the computer. Quote Link to comment Share on other sites More sharing options...
Bri-Guy-GA Posted October 26, 2005 Author Report Share Posted October 26, 2005 The car is in Alpharetta and has just shy of 70K on it. I am going to look at it Saturday. Will let you know. Will have to see how it compares to my Quest. You just get so used to feeling the boost as you hit the gas. I do have to say I won't miss the shifting in Atlanta traffic.

jeremy Posted October 26, 2005 Report Share Posted October 26, 2005 welcome aboard.........the TGP is a nice car, relatively quick for what it was and the era it came from, but the conquest should handle better in the twisties..... Quote Link to comment Share on other sites More sharing options...
john99gtp Posted October 26, 2005 Report Share Posted October 26, 2005 you should get the tgp just to get the tgp thats what i did Quote Link to comment Share on other sites More sharing options...

Yep, pretty sure that's the one I was thinking of. I think the guy with it wanted around $3K or just under that for it, which isn't bad for the mileage. It appeared to be in pretty nice condition aesthetically. Do you ever see any TGP's in your area? The majority of them in GA that I know about are located very near to you.

john99gtp Posted October 26, 2005 Report Share Posted October 26, 2005 and to think, i might add to the population down there in a eyar or so if its the same one, that one didnt look in bad of shape either. Quote Link to comment Share on other sites More sharing options...
