My buddy gave me a 5 speed trans from a 91 GP, i think the mounting bracket is still on it.  what information am i missing for this swap? First i think its a 284?
manual flywheel, shifter+ cables, clutch pedal, MC (cut hole in floor), w-body axles, a little wiring,

does the crossover not fit w/ the 5 speed? and I need to make a custom Mount for the turbo and the 5 speed bracket? thanks guys for any help.

most of the issues involved with the swap is probably covered somewhere in this thread.

From a 91 GP it is a 284.  You will need the following

Flywheel
Clutch
Clutch Master Cylinder
Slave Cylinder
Hydraulic line that connects both
clutch pedal
Axles
Shifter
Shifter cables and small bracket that holds cables into floor
Custom turbo support bracket
Custom tuned chip
Wiring- includes soldering the big purple and yellow wires together in the harness that run to the P/N switch, and wiring in reverse light swtich, and extending speed sensor wires about a foot to reach for the manual

IMO not extremely difficult, but time consuming!

thanks,  doesnt seem that bad,  will axles , shifter and cables, cmc, clutch pedal work from an 89 5 speed?  I found a white 89 5 speed in great condition in a junkyard...hopfully i could get a lot of stuff off that...but i think its a 282

IMO, grab EVERYTHING from the grand prix including the tranny and use that.  I know they are different, and most parts will NOT interchange.  Use the 282 trans and accesories

The car is on  a steep ass hill, id have to drag it off the hill to strip everything...  TGPNick, no pics, what parts are you looking for?  The windows were down, the interior was filled with water and there was a snake in it...

I need a shifter boot, knob, and cables if they are in good shape and work properly.  That is, if you are not using them.
Thanks

I still think it's best if you could pull the thing on to flat ground and use the 282 stuff.....only because it's easier to find than the 284 stuff!  + they are rebuildable compared to the 284.

the 282 is rebuildable like posted but the parts are very expensive plus there is a long list of special tools needed to rebuild one. I have no clue how much money Jimmy spent on just tools to rebuild his. He did make a thread with pictures when we rebuilt his before the swap. There are some pictures of the tools needed. I am glad we rebuilt his because after pulling it apart we found some parts that wouldn't have held up long. We also had to make a shim because the shim aren't available anymore and we couldn't find a used one. Here is a link to his thread in the first post there is a link to his photbucket album the pictures of his trans apart start at the bottom of the first page. http://www.tgpforums.com/index.php?topic=3756.msg25900#msg25900

    If you decide to rebuild use one of these.   http://www.phantomgrip.com/products.htm     This will make both front tires turn equally. It will also help with torque steer and your differential will last longer..  later

Hey, this thread was a while ago but my buddy has a few 2.8 barettas sitting in his J/y, can anyone confirm if they would be 282s? Will everything interchange? Not sure if the cars have abs or how much trouble that would put me in...  Its going in my stock tgp so hopefully it wont blow apart right away...  i just need a few tips from you 5 speed guys, im going to just drop the drivers side subframe and have at it?

they are 282s, but they won't work in a W-body because there is no place to bolt the W-body 282 tranny mount onto the case.  i guess you could get creative and make it work.
