So far I haven't found anyone to answer this question.

But I've measured the input shaft and pilot diameters on the Nissand Chevy, and they are different.The Chevy has thicker splines, but a smaller(!) and shorter pilot shaft than the Nissan.
So you can't bolt a Nissan T5 up to a Chevy motor, even with a new bellhousing.

But the Ford might be possible. The trick is to buy two plastic clutch alignment tools for a Nissan and Ford and compare the, that's what I did for the Chevy.

Maybe this weekend.........

But Fords into Zcars have fewer kits and motormounts available...........and replacement bellhousings are $$.
Better to just get a proper trans.

 

even though i have a turbo z and i am a ford technician i havent tried bolting a ford t5 to a zxt bellhousing.i think it bolt together but the input shaft spline count is different.maybe a 240mm pressure plate with a mustang clutch disc under it.i run a 82 zx na trans in my car but when i put bigger turbo and sds system on i might need bigger trans.

 

check the arcives i saw where a guy once say that an 1984 or 83 5.0 mustang transmission was the same borg-warner trans that came in the turbo's z's
