GTR Fuel Injectors

[GTRman1992]

I have one set of 6 R32 GTR fuel injectors for sale. $250 + postage.

[mr_rbman]

have these been cleaned or flow tested recently? Do u know if they r a direct fit for an rb20?

direct fit for rb20 rail but must have resistor pack to work.

[GTRman1992]

They have not been cleaned or flow tested. They came out of a working car, I upgraded.

resistor pack? please elaborate!

GTR's run low-impedance injectors, the ECU wants to drive high-impedance ones, so a resistor pask in between ups the impedance.

You can easily build one from JayCar 10W ceramic resistors for $10-20 depending on how neat you want it.

The transistors in the ECU for RB20/25 are designed to drive injectors with an impedence of around 12-15 ohms. The GTR (and toyota 440cc injectors I have) are 3-5 ohm so 6 resistors are required to splice in between the power wire to the injectors and the injectors themselves. The ECU then switches to earth on the other side of the injector to operate the injector.

It may work for a while without the resistors, but the eventual result is fried ECU

Then you are able to get the injector timing and pulse width modified (with an aftermarket ECU like PFC) so the car won't un too rich

Of course I must add that so is the GTR ECU, otherwise it wouldn't need the coil pack, would it?

Resistor pack even

:Oops: What Ash said........yeah

bump

[yogi000]

you still got the injectors??

[GTRman1992]

Yes, still got them.

[popamono]

willing to seperate?

require x2

[MNTL]

i require one but will buy 2 aswell to have a spare??

have a look at the dates of this thread, haha!
