series 2 rb25 on series 1 wiring loom

[z3n2k]

I currentyly have a series 1 rb25det in a 32 at the moment and i am doing an engine change on this and thinking of putting a rb25det series 2 engine from a 97 skyline.

I have mixed respones and mixed reactions from people on the forums and mechanics. Some say that you can put a Series 2 engine onto a Series 1 wiring loom/harness.

Can anyone confirm that this can be done otherwise i will need to source out a series 2 wiring loom/harness.

Is there any difference in the word wiring loom and wiring harness, different people use different words.

Can i series 1 wiring loom support a series 2 engine?

(Thinking the problem will be the coil packs since the wires on the series 1 go into the back of the engine where on series 2 there is a wire for each injectorm, is this correct?)

Any comments or help on this would be benefitical.

Cheers

harness is different as the series 1 has the little black box up the back... cant remember the name of it. ITs a sprak amplifier or something

Series 2 motor has the amplifier thingy on the actual coil packs themselves

which is totally different

yeah i realised that was the difference, i have heard that instead of connecting the plug to that little box up the back, you can run the 6 wires directly into the coil packs themselves?

Anyone tried this?

talk to Dezert Eagle. He has a R33 series 1 but UAS put in a RB25 from a S2.

the coil pack wiring from the s1 unplugs and just plug in the s2 coil loom.

hrmm interesting....

I have a s1 motor and loom and recently purchased splitfire s2 coils.

The coil plugs on the s1 loom dont fit onto the s2 coils so i need to use s2 plugs instead. I also need to remove the ignitor (black box at the back) and wire the wires into the coil loom.
