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 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

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

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

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.

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer 
    • Yes that’s another issue, I always have a front mount, plus will be turbo plus intake will big hasstle. I’ve been told if it looks stock they’re fine with it by a couple others who have done it ahahaha.    I know @Kinkstaah said the stock gtt airbox is limiting but I might just have to do that to avoid a defect so it atleast looks legit. Or an enclosed pod so it’s hidden away and feed air from the snorkel and below Intercooler holes like kinstaah mentioned. Hmm what to do
