Do you mean the R31, the 1985-1989 Skyline sold in Australia, Japan, and South Africa? It came with either the RB30 or the RB20. Or do you actually mean with the Z31, offered 1983-1989 in the US as the 300ZX, which came with the VG30DE/DE?
For what it's worth, I only know people with 240SX's who have swapped RB25 motors, and all three of them (WITHOUT EXCEPTION) have since sold their motorsets and put in LS1's.
