Hey their Z people! This is my first forum ever. I'm looking for some insight on upgrading injectors on a Z31. Currently I'm in the process of finishing my na2t project on my 87 NA z. The only missing peice to the puzzel is the fuel injectors. Ive upgraded the fuel pump and I'm running the nistune ecu with the mustang maf. I read on Jason's red Z site that you can run rx7 injectors, that is if you use his z31 parts fuel rail which is currently and not going to be in stock for a while. Or another option is to use the mercedes benz injectors with the older top feed fuel rail which im not interested in because you only get 4xx cc's out of.

My question to those who have upgraded their Z31 injectors is how, what injectors did you use?

I'm looking for side feed injectors with 550cc's or greater that bolt right on. Ill appreciate any advice thnx...
