Transmission for RWD KA24DE engine block is no problemo: Z-series or KA-series transmissions may be used. Same bell-pattern.

KA24E came in 1989-1992 U12 Pintara (T trims).

On KAs, I'm not 100% sure, but think 1) the FWD versions use a different bell-pattern than RWD versions 2) Oil pans differ and you can't swap them (rear sump or front sump). Although some guys say you can swap pans, so perhaps some versions swap. But I think some KA pans won't fit on some other KA engines. Proceed with caution or just modify your crossmember to suit the pan.

* USA Nissan Pickup (D21 & D22) is rear sump
* USA Nissan 240SX (S13 & S14) is front sump
