Which Loom To Work With?

[Skylsh32]

Hey guys,

I'm planning to put a rb25det neo engine into my R32 but I don't have the complete loom for it (well my one is all cut up still have most of the plugs) and now I am looking at wiring up a z32 ecu using another engine loom as sourcing the r34's complete loom, ecu, boost sensors etc is a bit of a mission, so I was wondering which engine loom is going to be most easiest to work with to get the neo running, is it the rb20det, rb25det series 1 or 2? I will be using the rb25det series 2 IACV and cold start valve and possibly the rb20det tps.

thanks in advance.

U can use either rb20 or 25's loom.

Rb20 loom u will need the ignitor and coilpacks from an rb20, u will also need to get a vct controller. and u can use the rb20 ecu also

If u use the rb25 loom it will need to be modified if u use the rb20 tps (swap plugs) and the z32 ecu(NIStune) will need a special base map loaded onto it to suit the rb20 tps

Sweet thanks will the CAS need modifying too if I was to use the rb25det series 1 loom? I have read that you need to reverse the pinout of the plug?

The r34 cas is different and late series 2 25.

Not sure on rb20 and series 1 rb25 cas wiring
