Might be worth it to avoid the headache of tracking down the right ecu/harness for the motor. I believe they changed ecu's depending on the years...

try: z31.com :: Index

They have a pretty decent for sale section.

They didn't make many turbos to begin with. $400 for 20 year old parts that are hard to come by and actually work = worth it.

main difference in z31 ecus are as follows:

Injector Impedence:
84-87(all) low impedence injector drivers
88-89(all) high impedence injector drivers

O2 Sensor:
1984-1985; 1987-1989 NA: Zirconia
1986 NA & Turbo: Titania
1987-1989 Turbo: Titania

Turbo/NA ECU Difference:
Knock Sensor input, which is arguable in it's effectiveness.

Lots of folks do NA-> Turbo conversions on Z31's and don't use the stock knock sensor (as in they don't swap ECU's). All you really need is the motor, the proper ECU for the injectors/O2 sensor you have and a tune.
Lots more info is available at z31.com, and z31performance.com

Ideal solution, but just doing a stock na2t, he may be able to use his stock ECU, depending on what year the turbo motor came out of

You need to find out what year the turbo motor is. That will tell you what year ECU you will need

Then you should be able to use your stock ecu if you get it reprogrammed with a 1986 turbo ecu image.
