Resistor box with aftermarket injectors?

[smart_garrett]

Hey guys,

I have a Rb20det in throwing some 444cc Deatschwerks injectors into. My question is do I have to unplug the injector resistor box on the passenger side of the engine bay or should I leave it in? Thanks for any help

Depends on the resistance of the injectors. If they're near stock like 2-3 ohms then you need them. If they're 12 ohm injectors you have to bypass the resistor box.

Go to the Deatschwerks website plug in the injector part number and all will be revealed.

RB20DET stock injectors are high impedance. RB26DETT stock injectors are low impedance. Guess which one had the resistor box.

Use a multimeter, done.

My point (as quoted above) was that there are no resistors in the injector circuit on an RB20. Repeat, there IS NOT A 6 PACK OF IMPEDANCE MATCHING RESISTORS, such as is found on RB26s. RB20 injectors are high impedance. Nearly all modern injectors are also. Therefore, there is no reason to change anything when putting new injectors on an RB20.

Why would OP mention a resistor box then? Sounds like something is interesting there.

The silver box resistor on the LHS suspension tower, stamped JECS 15-000J01 is the fuel pump dropping resistor. People always ask what that is.

WOW! That's what i thought it was and a SHOP!!!! was telling me it was for the injectors...... wow, i got so confused.
