I believe the only engines available are the 3.0 Liter N/A and the 3.0 Liter Turbo
Actually, with the right tools, patience, research, etc. there is somewhat of an array of motors that can swap into your Z. A friend of mine is in the middle of a Z32 Twin Turbo motor into his 85 Z31. In Japan there were more engines offered than here in the U.S. with different models of the Z such as the 300ZR. Check it out. The RB20DET inline 6 turbo motor found in the Skyline came in the ZR. There was also a 2 liter V6 called the VG20DET, also turbo hence the "T" in the engine code. Most Nissan engines and transmissions over the years will simply bolt into eachother's engine bays with little to no modifications. Another motor to consider is the ever popular SR20DET 2 lliter turbo inline 4 out of the Nissan Silvia. All of these motors are better than your stock V6, in power and reliability probably too. Do some research, see what works for you and your budget then make the choice.
