Putting A Rb25 Into A R32 Questions

[yoshiii335]

Hello

If I decide to go the rb25 into the r32, there is a place in the states where I can get a wiring harness that has already been made to use with a rb25 into a r32. It has been made to have everything working such as the windshield wipers, VCT, etc.

So I have read that I would bolt the rb20's acillearies onto the rb25. But I read that some people had problems with the powersteering pump since it only has one hose from it compared to the rb20's which has three, two for the hicas and that getting the powersteering belt with the correct length is difficult.

The old posts that I read about this didnt have any clear cut solutions.

What are some solutions for this? My hicas is working so I do not want to take it out.

Everything that has ever been written about putting 25s in R32s on this site is still here.

My 2c. Piss off HICAS. It doesn't matter if it's working. If it's working, it is still working worthless junk, rather than working useful stuff. Getting rid of it makes a lot of your PS pump problems just go away.

You're finally taking out advice, also you can use the RB20DET engine harness fine, however you need to swap 2x injector pins and run a VCT trigger wore separately into the engine bay.

Just use the RB25 sensors spliced into the RB20DET loom.

I bought my loom from Wiring Specialties in the US. I'm very happy with the purchase, it's awesome quality...

I used factory loom, didn't swap pins on the ecu.yet as I have to swap the injector harness plugs I swapped two around there. Had to extend about 6 wires to yet that was more manifold issue as not factory. Hicas, if your serious just keep the 20 pump and swap balancer so the fan belts the right number of ribs

Had to add one wire into the loom to for vct and a pin at the ecu.... Then after a few months I cut the ecu end off and wired in an aftermarket ecu anyway

How is it? Was it easy to install? Did you have to splice anything? Does everything work?

I put an rb25 into an r33 and worked just fine, runs like from factory, so can be done fo' sure.

I had to change my gearbox plug, but that was probably because I didn't specify the correct one when I ordered the loom. I also extended one of the plugs because it wouldn't reach with the way I wanted to route the loom. But everything works well with the loom (including aircon) however it doesn't control the power steering, but that didn't bother me as I run a manual voltage controller for the solenoid.
