Rb20det Loom On Rb30et

[shakotan-cefiro]

ok iam replacing the rb20det in my cefiro with an rb30et can i use the rb20 loom ?

[Luciano]

i highly doubt it mate.

Nope.

The loom connects mostly at the heads, so use whatever loom the heads are from...in this case, 30ET.

You might need to rewire the knock sensor wires, and you will probably need to rewire internals, where it connects to the relays and shit.

Get a R32 rb25de head and put that onto the 30 bottom end then the 20 loom will plug in. Win Win.

as said above if your doing a 25/30 and arent running vct u need a 20loom and ecu but also need to put 20 cams or use a 25de head from the later r32's

ok i think i need to clarify iam installing an rb30et

i currently have the 20det loom in the car and complete rb30et loom

can i leave the rb20det loom in to run accessories such as tacho speedo lights heater /fan

if not how much should i be paying to get this done by a sparky

please bear inmind iam not an electrician an although i have a fair mechanical knowledge electrics is where i struggle

The tacho wire u can get the signal from the 30et loom, there will be plug going from the ECU loom towards the dash this is where the dash gets all its signals from, so with a wiring diagram yes you could.

Speedo loom will be seperate to the ECU loom i would think, should have things like alternator, temp etc, this should be easily swapped to the 30et.

Lights etc should be seperate? Or do they run through the ECU loom? If so your option is to remove them from the 20det loom and splice them into the 30et loom so they can gp through the firewall with the 30et ECU loom.

Cant really guess a price on the cost, everycar is different, both being common engine's if you searched could probably come up with a wiring diagram that would help.

use the 30et loom mate , not a real big job to change , but get a sparky if your not 100% on being capable yourself
