ok peep i have read and taken in whats said on this sight

my issue is

i have access to a r34 n1 (vspec) engine and all associated elecs from a front cut

i want to put it into my r32 gtr and restore it back to a streetable package

i know there are a few wiring cam and cas differences

however i was wondering can i use the r34 loom and ecu ect in the 32 without to much trouble?

any relevant attached posts / links would be greatfull

Links for what mate?

You simply use the entire R34 GTR ignition system. coil/CAS to loom to ECU.

If you need further information above that then your going to struggle to do a conversion at all!

Pull it out of one, put it into the other. you have a front cut so it's all there!

Ash are you forgetting that the ECU loom plugs into the body loom as well?

Ive no experience on this directly but im assuming that the 34 ECU loom wouldnt plug into the 32 body loom.

In GTS/t, the 32, 33, 34 these plugs are all different.

You would be better off using a 32 CAS, sensors and Ignition systems with the 32 ECU loom dude.

Unless I'm recalling this very badly from when i did mine...

the loom goes from ECU plug to where you plug in the coil pack loom. My one from Nissan came as one complete part. The body loom should be plug and play as the GTR loom was almost perfectly plug/play into my HR31.

So assumption is GTR to GTR would be identical?

I'm only saying what i am as he wants to use 34ecu and loom, so its literally a swap in/swap out job. take a couple hours at best.

i would use your R32 ignition setup (coils, ignitor and harness). use your 32 ecu and harness. Keep the R34 cas (as 32 cas won't match the 34 drive on the cam snout) but you need to swap 2 wires around to get it working with the 32 ecu. simple as that.

other than that there are a few little differences. top radiator pipe on the engine is different. bolt your 32 one onto the 34 engine. that's about it off the top of my head.

much easier this way.

oh, put your R32 sump onto the 34 engine too. otherwise you will have one major problem. the 34 front gearing is massively different to the R32, so if you use the 34 diff and sump you'll end up with different ratios front and rear. with both engines out of the car it's easier to just swap sumps rather that set up the old 32 diff into the 34 housing. and there is no advantage in using the 34 sump over your 32 one. same goes for the diff centre, they are both open diffs, just with different crown wheel to pinion ratios.

definately not true. the hr31 body plug is massively different to later skylines. your confusing it for something else, or your car was already modified. afaik every model has a different plug to suit its own electric package

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
