vr4 engine

I was wondering if I have a 1995 3000gt SL and was thinking of buying a 1992 vr4 engine to swap with it. Will that be possible? If it is what kind of problems does it have when swapping engines?

You would need to do some rewiring. 95's have a hybrid ECU, 92'd have OBDI. With that said you would likely want to swap out to a TT ECU if you went that route. Read the FAQ thread posted in the sticky area as it will answer some of your questions about swapping from n/a to TT.

Technically no rewiring needed.

He could put the 92 engine in, using the NA harness and NA ECU, or even a 1g TT ECU, and not have any issues with OBD or hybrid.

The only rewiring would be for the CAS.

NA ECU on a TT swap FTL.

You can use a NA ECU with a piggyback. People do it all the time. It is better to use a TT ecu though as it has the proper fuel maps for boost, etc.
