will a old wrecked 92 z28 i know of work...its has a good t-5 in it that i could use....it was hooked to a 305 TPI though so would it hook to my V6 and is it a lot of work hanging the pedals up and stuff....what is the hardest part about this swap and are there some tutorials for doing this?

hardest part is getting all the stuff in correctly...thats why it took me nearly a month to do (it was all by myself...) pedals are a pain in the *** too, u need to worry about the brake booster since the pedal bolts are also for the brake booster, then u need to cut holes for the hydraulics which were a royal pain to line up right since they are under the brake booster...

a V8 doesn't share the same bellhousing bolt pattern as a V6, so no it wouldn't work. V6 T5's are all over in the junkyards here, shouldn't be hard to find a good one.

 

could i still use the v8 tranny though, and get a v6 bell housing? I really would like to use the 92 z one if i could cause it is stronger i think....not sure though. I plan on doing some major mods to the v6 including the 3.4 swap so i want something that can hold up to the power and maybe a turbo

 

The V8 tranny will fit in the V6 bellhousing but that's not where the problem lies. Since I'm contemplating the same swap I found thru some trans experts that the V8 one will handle the power/torque better due to the way the input shaft assembly/gearing are designed in the ratio ( v8 has a 2.95 first, compare to a V6 which has something near 4.0) From what I was told, the lower the gear ratio had a direct impact on the durabilty/ability of the drive gears and main shaft/countershaft gear cluster to handle the power.
Since you have an LB8 (V6) the stock T-5 is an MB1 whereas the stock V8 uses the M-39. The internal parts are obviously not interchangeable.
If you want to use the V8 T-5 you'll have to modify the V6 clutch to accept the T-5 input or "main drive" shaft. This is possible to do while retaining the V6 pressure plate and flywheel stuff. The v8 clutch,flywheel and pressure plate are not interchangeable. The V6 clutch is 14 spline, v8 26.

 

partly right actually..not totally... im using a v8 input shaft with a v8 clutch and pressure plate (yes 26 spline) and the clutch fit the v6 flywheel even though i was told they wouldnt fit..

hum.........that can be a lot to take in sometimes. so the v8 one would hold up a lot better though right?

 

how much power u looking at making? cost/verse necessity is a big thing...

In theory, these parts are not interchangeable, though I'm surprised that the bolt pattern of the V6 flywheel matches that of the v8 pressure plate. The v8 flywheel is 10.5-inches, but I'm not sure what the v6 is. So, your saying that no mods at all were needed to make this combo work?

 

ill go to my tranny guy to make sure on the clutch portion.. i know the input shaft went in and he only had to fab one thing (im not sure what it is)

I'm pretty sure the v8 T-5 input shaft is different but if everything else is v8 then all should be OK.

I would recommend that you find the right clutch components for the V6 though. The clutch/pressure plate/flywheel combo is a funny thing, one little bit out of whack and the car will difficult/impossible to drive. Trust me I think I finally fixed mine one year after the swap.

The internals of the tranny are the same between v6 and v8.

The bellhousing will need to be changed.

Check the tech articles on this site for a tutorial. It is what I used to do the swap and it is pretty much right on.
