I picked up a set of 7mgte injectors and clips for my rb20det. I cant find any infomation online to help me wire the clips in. Can anyone shine some light on my problem.


P.S. I know I need resisters.

They don't have a polarity, but you want to keep it common between all of them.

It really won't matter. But according to the manual, terminal 1 harness side at the injector is from the dropping resistor or battery source. Terminal 2 harness side is ground from the ECU (which is the switched/controlled side of the circuit).

What are you doing to compensate for the extra fuel the injectors are going to put out? stock = 270cc supra = 440cc.

Mine are 220cc (redtop rb20det long story), but I got a fuel pressure reg and am getting CarlH to chip it for me. At least thats the plan. I have a rb25 turbo on it.

I feel like I should shed some light on the whole redtop thing. I kinda got screwed into using it. So I am going to make the best out of it. I have done a lot of research, and found that the main difference from the silver top eccs and the redtop eccs is the wireing and the intake ports on the head. The redtop uses 12 smaller ports because it still uses the butterfly plate. I am in the mddle of removing the butterflies and minor port work to open the small ports up and port match everything together. What about the wiring you ask? Well I have everything off a silvertop readdy to go on it. Cas, coils, knock sensors, wiring harness, and ecu. People have done the vary same thing in Aus.
