Does anyone have any information on putting a manual transmission behind a Turbo V6?
yeah dont do it! it will be hard to maintain boost while shifting, also u won't be able to build boost at the line if u run at the track. A T5 can bolt up to a turbo 3.8, but as well all know T5's blow, and from what i'm told a t-56 won't bolt up...i was thinking about going to a manual when i drop a turbo 3.8 into my 89 GTA but EVERY GN/TTA guy told me not to for the reasons i mentioned above

If a T-5 will bolt up, what bell housing would you need to use?
i "think" a bellhousing from a 4thgen 3.8/5speed this is what i've been told, just heresay, do don't yell at me if i'm wrong
Ok, here is what you have to do to put a stick behind a Buick V6.
McCleod Scattershield (Chevy/BOP dual pattern model) or find a 65-81 BOP bellhousing as these have the dual starter pockets. These both will mount the Muncie/Saginaw/GM spec BW Super T-10 AND Ford Top Loader/ Ford Spec BW T-10/Tremec 3550's. Both bellhousings are set up for a rod linkage mechanical clutch. Keep that in mind for whatever chassis you plan on doing this in. You could get a Tilton or McCLeod hydraulic throwout bearing set up. Again, these are $400+ for all the pieces and you still need a set of pedals and a master cylinder for it.
Centerforce steel flywheel (this is the only steel one that I could find manufactured. There are aluminum models out there for $400-$500, but they are way too light for a turbocharged engine)
The centerforce is 160 teeth and will mount 10.4 and 11inch clutches. The problems are it is about $300+ dollars and then you must balance it to match your engine which means the engine must be torn down. These are not a bolt. If you are willing to waste an engine, go ahead, but the amount of weight is dramatically different than the factory balance.
The next item is a pilot bushing for the back of the crank. I found that one for a Chevrolet fit like a glove.
If you plan on using a T5, be aware that the factory bellhousing is a Chevrolet pattern only and tilts the box on a 15degree (I think) angle to clear the F bodies trans tunnel.
The T5 will bolt to a Muncie/Saginaw pattern bell housing, but you will need to make a wedge for the transmount and fabricate a new shifter lever as the angle will be way off.
The late model 3800 as Tony Iwasko mentioned uses the FWD pattern and is not a older BOP pattern as the RWD engines were up to 87 in the G bodies and in the 89 TTA.
My advice to you is dont do it. It isnt worth it and by the time you get done doing it, you will have spent more money to go slower.
