Rb20e And Rb20det Loom Issues.

[Nismo_Boy]

Hey everyone,

I’m in the process of converting a car from rb20e to rb20det, now, what can be used on the original loom? The rb20det loom isn’t complete as the motor and box didn’t come from a half cut.

Can the DE loom be spliced some how? So it all works, or am I going to have to look for a complete rb20det loom and just swap it over?

Any help would be much appreciated. The standard ECU will be used to get the car up and mobile, then an after market item will be used

joshwa.. do you have a diagram of the rb20e wiring, or at least ecu pinout ? if so I can tell you what the differences are. To be honest I can't think of too much that would be different.. its not like the turbo has any wiring coming off it.

I have the complete RB20det wiring diagrams, so if you could get the rb20e stuff i can have a quick look and compare.

hmm.. I've remembered I already had that..

Here you go. You love me more now.

The FPCM (which appears like its not on rb20de) drops the voltage on the fuel pump at idle, but probably isn't mandatory. Thats rigged up near the boot anyhow.

Just rig up the knock sensors - that's pretty much two wires direct to the sensors and a ground off each. I can't see why the rb20de would have them, but in the diagram it doesn't say that they are specific to rb20det.

Everything else looks identical so away you go.
