Both ka24e(de) and the vg30de from the z32 (not the turbo one) use the fs5w71c... the bellhousing is different along with the shifter assembly, but the transmission is the same... along with the rb20det, the vg30e in the S12, the mkII ca20e, s13 sr20det, etc... all the bellhousing swaps from one to the other, but the tailshaft assembly (where the shifter is bolted) is different from one tranny to the other depending on the platform it was used on and the gear ratio are also quite different.... so basicly, if you swap a qr25 bellhousing out of a frontier (if it uses the fs5w71c as stated above) with a s12 mkII tranny, you will have a bolt on tranny with the qr25 block and the stock driveshaft yoke and tranny cross member... as for the qr25, i quess we're talking about custom mount...

ok.. I was wrong on the fs5w71c being used in the z32 n/a... but the rest is accurate so you cannot bolt a z32 transmision (n/a or turbo) onto a fs5w71c bellhousing... but that doesn't change anything right??
...Well I've done some research, and it seems that the 2005+ frontier that uses the qr25 doesn't use the fs5w71c, the old one using the vg33e used to be bolted to it, but not the one using the qr25... so we are talking custom transmission crossmember and custom driveshaft with the correct yoke... so a qr25 into a s12 is no bolt-on affaire... but it would be quite cool IMO
