Might be helpful if you explained what you needed them for. You're not going to find that information anywhere but probably Nissan itself or anyone who modifys Z31 ECUs.
Drivers aren't generally something that can be messed with by people with common tools. If you are looking at beefing up the drivers for larger injectors, that's not a problem as long as you use the correct type of low impedance turbo (in your case) injector. Beefing up drivers generally requires a professional to modify the ECU. Modified ECUS can probably generally be bought for cheaper than if you tried to assemble the tools to do it yourself. If you have a driver problem, it would be easier to acquire a new ECU than it would be to fix the driver problem.
I"m grasping at straws here, because I have no idea what your intentions are.......

Near as I recall, there are only 2 drivers in the ECU anyway, one for each bank of injectors. When engine rpm passes 3000, the ECU reverts to batch fire, which fires all the injectors on each cylinders intake phase..... I know it was this way in the 85-86 ECUs, I don't think the 88s were any different. If they are then nevermind, since my experience is with the early models only. If this is the case, I don't think the addition of a couple more injectors is going to make much difference. I'm assuming you are going to use a TB injector plate.

i got the car with 2 injectors mounted on the chargetube and an adjustable pressure switch.
but the way they had it, at 10 psi 2 injectors open up with no pulsewhith.
so i pull it out and replaced the stock injector with 10% over stock injector.
i notice a 32 degree increase in intake temp and had bad pinging do to rasing the compression
i/e going form 7.8:1 to 9.0:1. the a/f mixture is 13.4:1 i dont want to go much more richer because i have to use a cat and im running 15psi boost i got great gains from this setup and full boost at a lower rpm
but most important i got an ass load of mid torque which i need for road racing
i know a good intercooler would likely solve my problem
but i'am really in to building my own liquid aftercooler
oh ya it came with a ecu modify by jim wolf to handel 450cc injector and is using a mass airflow meter out of a 03 cobra
hay thank you for your help i get a lot of crap for trying something different
Yeah sounds like a pretty comprehensive setup you have so far. If you want injector driver specs, you might try contacting JWT, if they can't tell you nobody can..... I also had an idea for an air/water IC, but never had the time or adequate aluminum welding knowledge to begin the project. My idea was to literally encase a DSM or Supra TT side-mount IC in an aluminum shell and fill with ice water, with inlet and outlet tubes going to a small trunk mounted ice water tank. WRX's also have available aftermarket air/water ICs, but they are probably too small for your application and they are fairly expensive. I like to see people try to think differently about tuning, while the done-to-death ways are great there is no decent challenge in doing something the 5000 people before you did.......
