so i found 2 grand ams down in florida in which both say are v6 5spd manuals... so heres the question.. does anyone know how reliable a 5spd is with having a turbo, etc...? i figured i'd attempt to get one and pull a tranny swap this winter if it's worth it

i dont think anyone has been able to prove relyability of the 5 spd behind a v6... i havnt heard its not relyable but i also havnt heard that it is relyable either because of the simple fact that there hasnt been many people to actually complete the swap and proove any kind of power limits. and having a turbo on top of that would be interesting to see what the 5 spd yeilds as far as performance benchmarks compared to the g6 6spd that fiero guys bolt up to blown v8's putting out out over 400whp with no problems. i guess finding out what the 5 spd is rated to hp and torque wise would be your first step if your serious about going through with this

yeah i thought that the 5spds only came with the 4 bangers, but both of them from florida had v6 5spd so not sure

There are NO 5 spd GT's (99-05 V6) unless someone modded the car. IIRC, the only V6's that had 5 spd on them were in the early to mid 90 models. The Z-24s and the Sunbird GT's had them but they were 3.1L

could have been a type-o. but what if they are 4 cylinders.. would that tranny not perform well?

5 spd manual GT's do exist. Pontiac made some as concepts when they were toying with the SC/T idea. Not sure if they were ever sold though.

Most of those cars were crushed, what was left which was like 2, was sold at auction.

They made one, thats all. That car no longer exists either. None were ever sold either.

The only GA's that ever had manuals were four cylinders. You can make a 5spd or 6spd work with the 3400, but it takes a good bit of customizing and parts plus a little custom wiring and tuning in the pcm. The manual transmissions will give an advantage over the automatics in weight, efficiency, and gearing. I don't know about their durability and torque capacity though. Obviously you can upgrade the clutch and fly wheel, but I don't know how much the actual gears and other parts will handle. Seems they will take at least into the 400hp range, possibly more. You can handle at least that much with a built 4T45E, and more with a built 4T65E-HD, so what tranny you want depends on your purpose for the car. If I was building an all out drag car with a goal of 500hp or more I'd go with the 4T65 for consistency.

Um hello the 3.1 block has per GM have been the exact same 60* engine since the 2.8 that it derived from and is also used in the 3.4 that is in the GA-GT. So manuals that will bolt to any 2.8 or 3.1 with mods to mounts and such will bolt up. How ever as Aaron says their dependability and durability have not been proven for performance. i will ad link to this info later

Do you ever read time stamps?
