Modding primary rail
Im in the process of putting together my gt35, i have a fuel rail, fuel pump, and 1600 cc injectors. Im planning on using my 850 as my primaries.
The problem at this point is I dont know what i need to do to modd the primary rail. I read about it but cant find a thread about it showing what needs to be done..
Any help, or link would be much appreaciated..

I found this just to make sure I wasn't imagining something.

Unless you are planning to make a lot of power, 850 primaries are hard to properly tune idle and low cruise.
Use 550 primaries with the FJO driver for the Bosch 1600 secondaries, and you will have a lot of fuel with a system easier to properly tune.
My duty cycle at 15psi boost is only 69% with this setup. Before with resistors on the 1600, it was in the high 70%.

Another thing to note, I'm using an Xcessive LIM, which elimates the air injection at idle to the primary rail...
