90moddedtgp Posted August 8, 2004 Report Share Posted August 8, 2004 i have a 90 tgp that has almost nothing left that is stock and one of the last mods that i would like to do is put a manual in it i know that for a while they had the grand prixs in sticks i was wondering if any one knew where i could get a car that as a stick so i could get the trans and the console thanks Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted August 8, 2004 Report Share Posted August 8, 2004 88-90 Grand Prixs and Cutlasses had the Getrag 282. 91-93 Grand Prixs, Cutlasses and Z34s had the Getrag 284. Quote Link to comment Share on other sites More sharing options...
Pontiac6KSTEAWD Posted August 8, 2004 Report Share Posted August 8, 2004 But everyone keeps blowing up the 282's. And the 284 Is so heavy I have heard. I am still wondering if it was posible to use a 4 speed out of a 2.8 Fiero or Citation. I dont know what kinda trans it is, but I think they were more designed for power. Just an idea I had....

god910 Posted August 8, 2004 Report Share Posted August 8, 2004 I blew a bigass HOLE in mine, but I'm getting another one soon. I trust the transmission, just not the people that put it together. Every one that's broken either had 200K on the clock, or was recently rebuilt (obviously by people that don't understand what kind of power the cars are making. Curtis uses a 282, and he's in the 12's. So, if it was as bad as people think, wouldn't he be using something else? It has it's problems, but you can work around them, just like every piece of automobile machinery. Nothings perfect. Get the whole car when you're doing the swap, that way if you forget something (or like has happened to other people, you don't realize you need something) it'll be right there until YOU decide to scrap it.

90moddedtgp Posted August 11, 2004 Author Report Share Posted August 11, 2004 it. has forged rods and pistons from wisco. it has a roller rocker setup from crane cams. we put a garret gt28 rs ball baring turbo on it. we got the jeffm chip and x-over pipe. a msd 6 digital setup with the msd coils also. an hks dual stage blow off valve cat back exhaust. depending on what it runs in the 1/4 we have a small shot of nitrous. but i would like to put that on my stang so hopefully it runs good enough with out it the interior is pretty much left alone but we did take out the cumputer in front of the shifer and made a gauge culter with boost fuel pressure mixture gauge and exhaust temp the i also rebuilt the trans we went through the suspension and put different springs on it and new half shafts and better brakes the last thing were are thinking of ordering is a bigger intercooler i think that is every thing and hopefully it will be runing with in the next week because we just put the new turbo and roller rockers on so the motor still is not back in the car Quote Link to comment Share on other sites More sharing options...
gp90se Posted August 11, 2004 Report Share Posted August 11, 2004 I know im very interested in seeing pics of this car, the wiring for the MSD box mostly because I was looking to do with mine with a boost retard box. any reason a change the the spring, the TGP 1s seem to plant power 2 the ground fairly well and corner decently.

90moddedtgp Posted August 11, 2004 Author Report Share Posted August 11, 2004 the springs were also to lower the car i wish i knew ho the car is going to run because i have no idea what to expect because the first night i had the car the engine blew up and i just started doing mods in the rebuild does any one have any guesses on what they think in might run in the 1/4 Quote Link to comment Share on other sites More sharing options...
tgpguy21 Posted August 11, 2004 Report Share Posted August 11, 2004 Im just going to take a wild guess and say high 12's low 13's? Anyone else have any opinions? Quote Link to comment Share on other sites More sharing options...
skalor Posted August 12, 2004 Report Share Posted August 12, 2004 Pics!! :shock: I would have went with a GT2871R as it's a step up from the disco potato. Oh and how was the potato install?? What needed to be changed?? How much was the potato if you don't mind answering...I was quoted around $950 a couple months ago. I figured that one downpipe hole needs to be filed, different oil/water fittings(banjo style). What compression are you're internals?? Did Jeff M. custom make you a chip or is it just a regular TopGun?? Quote Link to comment Share on other sites More sharing options...
90moddedtgp Posted August 12, 2004 Author Report Share Posted August 12, 2004 i am going to get some pics up soon but my parents went out of town and took my digital camera jeff custom made a chip for the mods done to the car do you guys think that high 12 is the best that i could do i thight that i might be a little faster than that Quote Link to comment Share on other sites More sharing options...
skalor Posted August 12, 2004 Report Share Posted August 12, 2004 To answer that correctly we need to know a couple things first. What's your compression ratio?? How much boost are you running?? Any other mods that may affect power. Now assuming that your running around 14 psi because the GT28RS is much more efficient than the stocker, and you're running that detonation free with some good timing. Also assuming that your compression ratio is between 8.5 and 9.0. I think that your looking at low 13s at best, and that's also assuming good weather, good track, and a good launch(2.2 60' or better). Your treading in unknown waters and if you get lower than a high 13 and produce a timeslip your looking at having the fastest proven TGP. Now, get that TGP done and get it to the track. 8) Quote Link to comment Share on other sites More sharing options...
90moddedtgp Posted August 13, 2004 Author Report Share Posted August 13, 2004 it is almost done we just got the new bit so we could finish the push rods sorry i forgot to answer all the questions it was late we are running about 8.0-1 and when we go to the track we are going to turn up the boost to about 18 we are going to break the cam in also forgot to mention that there is a crane cams cam in ther and at this moment i do not remeber the exact lift but it is not stock i bought it along time ago when i first got the car any ways once the motor is good and broken in and i have done a few oil changes and fixed all the bugs it will go down the track once and we are going to sell the car we now have two corvettes we are working on and i drive a ford so that takes some time if you know what i mean but any way i am going to pick up that car we bought and we will make it a stick and as long as that goes good it should be running in a couple of weeks trust me i want to drive and maybe have the fastest tgp ever that would be cool any ways sorry for typing so much about nothing really talk you all later Quote Link to comment Share on other sites More sharing options...

My guess is a low 13 second run witht hat setup Quote Link to comment Share on other sites More sharing options...
TurboZ24 Posted August 14, 2004 Report Share Posted August 14, 2004 Yes, I do run a stock 282, but I have exploded one differential and at the same time, tore the mounting bosses off the tranny case. That tranny is now gone and the replacement is doing "ok", but the case seems to be shifting, because no matter how well I seal, clean, etc them they always end up with a slow fluid drip between the bellhousing and case... Oh, well. I have no idea what I'm going to do with the tranny here in a few weeks, I am finally replacing the headers, crossover, and swapping the turbine to a T4 P trim (A/R.. not so sure, probably start with .96, then work down if I don't like it). If the tranny has issues with 12 psi, I'm worried what will happen when I simply free up the exhaust, then raise the boost. Quote Link to comment Share on other sites More sharing options...

Well, either you're in denial, or you're playing stupid I would say you're case is torqueing, and making it leak Have you thought about a midplate/torque plate? I'm assuming you're using all solid mounts. W/ the stock log mani's is it even possible to run a 2.5" x-over? IF possible, would it be nec. I haven't measured the stocker, so I don't know how big it is, or how it flows, but after we relieve the turbo as being the bottleneck, will the x-over be next to go, or the manifolds? I have a question about the turbo, but I'll leave that to a PM. TIA. Quote Link to comment Share on other sites More sharing options...
TurboZ24 Posted August 14, 2004 Report Share Posted August 14, 2004 Well, either you're in denial, or you're playing stupid I'm in denial....... I really want a different tranny, I also have high rpm issues with the HM-282. I'm assuming you're using all solid mounts. Yes, I do use solid mounts and will be adding an additional solid mount to the tranny case to "spread" the load from those mounting bosses. I do know that the GN guys run shorty headers with 2" collectors, which allow them to get into the 600-700 HP ranges without problems, so the 3.1 should be fine with 2" coming off each manifold. Also, the turbine inlet on even the T4 will barely accept two 2" pipes, so... As for the stock cast manifolds, no real idea, since I've always run headers on my current setup. If I had to guess, I'd say the stock turbo first, then probably the exhaust manifolds, and as long as the stock crossover has smooth flow, I'd think it would be fine.

Beretta Posted August 15, 2004 Report Share Posted August 15, 2004 what is the reason that niether the 2.3 or 3.1 5 speeds will fit on the tgp ? i am putting a tgp engine in my 1990 beretta 5 speed and heard they arent compatible.

Todd From what i understand in a berretta, the problem is that the transmission mount gets in the way of the turbo. I may be wrong, but thats how I got my first TGP. Guy was going to put it in a berreta, and couldnt cause of that.. Quote Link to comment Share on other sites More sharing options...
TurboZ24 Posted August 15, 2004 Report Share Posted August 15, 2004 Yes, the upper tranny mount get's in the way of the stock TGP crossover pipe. You either have to redo the mounting structure or build a custom crossover. Quote Link to comment Share on other sites More sharing options...
