Different length case. You can swap internals, though.Chuck Stong

Uhh no it is not a different length case. I have seen a wd21 30a used in a z31. I would like to see some documentation as to such if you have it.Chuck Stong

Even if the case is a different length, would it be too hard to slot or re-tap the mounts and get a custom driveshaft? Driveshafts are expensive, It turned out to be the most expensive individual purchase for my 5sp/NA2T operation.My beloved Z:1987 2+2 NA2T w/30a swap.

its more of a matter of the shifter being up in the radio. Thats why the Z32 tranny's have an extension linkage.[strike:ff0tp92h]1984 300ZXT[/strike:ff0tp92h]

I just had a tranny shop go through the truck tranny and install it in a z31 case.

Individual parts for the internals between the 30a for the z31 and trucks are different, and have different part numbers (which confirms the difference). Many of the parts are no longer available through nissan, so the only choice in rebuilding a tranny correctly was to swap the internals as a whole from a truck, and rebuild what it needed as those parts are available. It was not cheap, but much less than buying a new tranny.Chuck Stong

Since I have not put two side by side I'll give you the benefit of the doubt. But I know 100% that Al Dunbar put a wd21 30a in his 87 turbo when he swapped from auto to 5 speed and used a stock driveshaft from a 87-89 turbo.
As for internals being different I'm certain they are. The ratios are different for trucks and cars.
If the bellhousing was longer, the input shaft would have to be longer as well. Same goes for the output shaft and housing.
So how much longer do you think it is?

if you read that doc that comes on the fast disc it is regarding the r30a and the gearset/shaft combos you can use, and they have all prior and superceding parts numbers listed so you can match them in an approved manner... the doc is linked in the sticky r30 thread

If you're sure the housings are different lengths then I will take your word for it. Based on external visual inspection alone they looked about identical; how much longer is the Z31 trans? Since you were able to swap the internals I would take it just the output shaft and rear housing are different lengths?Chuck Stong
