Hi,
I am new to this forum and this is my first post. I do have a 12 injector set up on my 81 zx turbo coupe.
I have the injectors staged so when under boost the second set of injectors come on for added fuel, and the added precaution of running lean. The build and set up is almost complete and I'll update you both if you want.
My current set up is a new L28ET block (bottom end), ported and polished P90A head w/ HKS cam, Haltech E6K Engine Management Computer, MSD 7AL II ignition w/ pro coil, Turbonetics T60-1 Ceramic Ballbearing turbo, Cartech intercooler, Cartech wastegate and blow off valve, Aeromotive fuel pump w/ Aeromotive fuel pressure regulator.
I attached a link to my web page on zdriver.com which has a photo of the 2 injector rails.

If you have any questions, I'll try to answer as best as I can.
