Thinking about adapting an 'new' R34 GTR engine loom to an R32 GTR. Can anyone shed light on the differences? I know the R34 CAS is different, and for example you can't use an R34 Power FC on a 32 or 33 but not sure if this is because of the pin outs, the CAS (different on the R34) or if the whole lot is totally different.

Being an RB26 I'd have thought an R34 loom could be made to fit with a few changes.

Cheers

there is a lot of differences, the r34 picks all its power from in the car R32 takes it from behind lh headlight recess. its easier to retro fit r32 stuff onto r34 engine.

You could if you were patient swap all the electronic engine control gear from the r34 engine loom onto the r32 engine loom but only utilize the body / wiper / power portion.

I have done it all before (in our s13 i did the above so that it all plugged in as per factory) i have also done a R32 rb26 into S15 the same way but its ALOT of time and effort, especially in your case as the only benefit is internal igniter.

Thanks Trent

You mean retain the body/wiper/power portion of the R32 loom? I received this from Ray Hall re using my R32 V44 board:

The same plug-in ECU is used on the R32 and R34 GTR. There is a jumper on the base board that selects either model. So based on this you can use the R34 harness. I have no idea how this harness will connect to the engine, but the ECU end is correct.

my R32 GTR runs a 34 N1 Nur engine inc the 34 CAS etc. I will have to have a look and see how it's done. it all looks factory. I had it done in japan so I have NFI exacly how they did it. I'll have a look and see what coil packs it's running too.

it would just be a pin swap for the cas, nice and simple.

I have reread the post from scooby again and im a bit confused now. I though he wanted to run a r34 engine loom.

maybe he can clear this up and post exactly why he want so use a r34 loom. cause if it is just the CAS issue its a 2min fix with some tweezers :D

Thanks Trent and Richard

It's the R34 GTR engine loom I want to use. No problems yet, but 17 yo heat soaked wiring being what it is I'm looking to replace it, particularly since I already have the 34 loom.

Excellent point re the coil packs, hadn't considered them yet. I seem to remember they are different to 32/33. Look forward to hearing about that.

Cheers

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
