Interestingly enough the stock ECU in the RB26 does not have a low Z injector driver in it, even though the stock injectors are low Z.

The 26 actually has resistors built into the harness.

I don't remember if the RB26 injectors mechanically fit the RB20 rail/head (although my guess is they do), but electronically you can get by with just running external resistors for a dollar or 2 a piece. As always no matter what injectors you choose you will need something to tune with, which may likely be the highest cost component.

IMO nistune is a fantastic setup and supports the RB20. www.nistune.com
