Bretto - that makes sense now mate. The vct still isn't switching the way it's hooked up, it is just always activated.

Tuitahi - Off the top of my head that sounds right to me. Also have to change one other wire, it's for the power steering. A bunch of other wires from the z32 ecu become redundant.

I do have all the pinouts, i will put it up today/tonight sometime.

Sorry, heaps busy this week. :iluvff:

Cheers

Bretto - that makes sense now mate. The vct still isn't switching the way it's hooked up, it is just always activated.

exactly. like i said i dont know this sort of stuff to well so i was hoping it made sense. the only thing that we were a bit unsure about is that my battery went flat on sunday (got the car back friday night) and really the only difference that has been made since swapping the blocks is that the vct is wired into the fuse box to the ignition. any thoughts on whether that could possbly drain the battery??

i went to mercury website and there was no advertisment of re-maps,

i was previously on there site a month ago and found there pricing and everything on it but now its gone >_<

i might hit up google and find those pin-outs and have a sus

so you obviously didn't see the link in my post above yours?

ahaha i saw your link but didnt click on it

i searched there site yesterday ! obviously not quite enough

thanks mate but i seen it doesnt say anything about z32 ecu's..

so once im finished all this will it pretty much be a rb25 ecu in the z32 casing pretty much? thats simple terms of course

One would assume that if they have tapped into an ignition switched power supply then it should not drain the battery. However it does sound a bit suss that the battery started going flat after this wiring had been done. Get someone to double check that it is not hooked up to a direct feed from the battery.

Ok so with the wiring for the z32 ecu a bunch of wires are no longer needed so don't stress about them.

Z32 ECU CHANGED WIRES -

************************

Injector and ignition coil wiring. (double check, triple check, get it right)

19 and 34 need to be swapped over. (power steering switch)

R33 KNOCK SENSORS -

********************

The easy way to do it is just hook up only one knock sensor.

If you have a cro or multimeter you can rev the engine and check which knock sensor puts out the higher signal, then connect that one to the z32 ecu. Or just use the one closest to the firewall.

AUTO TRANS?

************

Dunno, never tried it on an auto. Feel free to have a bash.

Edited by TSL

It does not matter if the ecu is auto or manual. The hardware is the same, only the software is different. So you can use a manual map in an auto ecu and vice versa.

What i was saying before though is i haven't seen this ecu swap done on an auto before. I'm not really sure if the z32 ecu would communicate properly with an r33 auto trans.

Oh and of course while r32 ecu's are a dime a dozen, it seems to be more tricky to find a z32 ecu for a reasonable price.

Edited by TSL

picked one up for $100 delivered, pretty stoked !!

offtopic yesterday i knocked off my boost gauge T by accident and the car remained running perfect ! wtf ! i remember when i first put the engine in i did this and it died right away.. i think i have a leak else where so could my car adapt to a vac leak>?

thanks

yeh i had a think about about s2 and was wondering abit, im running s1 engine off s2 ecu atm.. hopefully il have some before and after results for everyone when this is done, im not expecting gains really just an easier way to live with rb25 interaction ahahah

  • 1 year later...

I just got my RB25DET (series 2) and I was hoping you could help me with some questions.

My Skyline is non turbo so it will be a big step with the RB25.

Now then, my first question is about the gearbox mounts, I hear they aren't the same and I will also have problems with the speedo meter. What do you know about this? Can I use the Xmember of the R33 ??

The second is about the harness, everyone that has ever swapped an engine told me that the harness is the most difficult part of the swap. Do you have the diagram of the R32 and the R33 (still can't find it for the R32) and some pointers on how this is done??

Hope to get a reply from you soon

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • 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
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • 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.
