Lots of problems. Don't do it. See the engine swap sticky in the Northstar forum.

I edited your title to make it more descriptive.

Yes, Huge issues.... forget about doing it. There are just too many differences between the 2000+ N*'s and the 1999 and earlier models. Go down to the sticky in the N* section of the board titled "N* Swaps what years are interchangeable and the differences"

Different engines, different management systems. Different wiring. Different management sensors.

You'll need to keep the same engine model within the 1999 year line, also - don't swap a VIN Y engine onto a VIN 9 transmission or vice versa.
