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

    • Hope you had a great time here in our tiny country.   The JDM scene we have here is quite small, it's mostly BMW, Volkswagen with burble tunes haha. But the few JDM cars we do have in the scene are pretty nice. Some of my friends drive cool s14's too. Both built engines, red one makes abt 500, blue one abt 400 i think?
    • Ye good idea , would have never thought of something like that. Might aswell do it to every pulley and the balancer while I’m there 
    • Use an LS1 or similar, via kit like Frenchy's. But.... It's probably not the alternator. It sounds like belt squeal, which would be because the pulleys are glazed. Rub every groove on the pulleys with 120 grit paper. Report back. Oh, and new belts afterwards too. The old new ones will be shitted up already.
    • Hello all I have 2 r34 sedans , one turbo one na, only recently aquired the na 34.  Man what is with these things.... My turbo 34 started sounding like a super charger, it was screaming at anything above 4000rpm , I took the alternator apart and replaced the front bearing which is the only one I think you can access and it did not fix the issue so presumably the bearing in the rear of the alternator is gone. ( diagnosed it was the alternator by taking off the aux belts one by one to figure out which pulley or bearing it was )  My friend gave me one he had lying around, Installed it , it did not squeal for maybe 500kms and now its started to squeal again briefly on startup  Recently got an na r34 and I replaced the timing belt, water pump + all the auxillirary belts. Runs amazing but it suddenly developed the same squeaking problem but significantly worse, Ive had my neighbour come down screaming at me because it was waking her up everytime I moved the car. It takes a good 2 minutes before it quietens down.  Im yet to diagnose where its coming from but im fairly sure its coming from the alternator aswell. My question isnt about how to fix it but rather where can you get a new alternator for an rb25 neo??? Ive searched everywhere but I havent been able to find a direct fit oem type replacement thats not genuine. All the automotive stores sell an oex one - BXA035 - which I picked up for cheap through a friend with staff discount , got it home only to find the connector is completelty different.... As far as im aware bxa035 is for rb20/30's and after a bit of figuring out the bxa035 has an ev14 type connector, which is tiny compared to the rb25 connector. I actually had an ev14 connector lying around which I was considering just replacing the bigger plug with to get the alternator working but the bxa035 is rated for 70amp vs the rb25 alternators are 90amp ( or so ive been told ? ) That paired along with the fact im about to install an amp + sub in the back and I have the stock sized small battery Im not sure itll do the job unless anyone has another opinion?  I know and have seen all the websites selling the ls1 alternator conversion kit but I am not going down that route, nor do I have the money to. Hopefully I can figure out how to get 2 brand new alternators for both cars. I would buy second hand which there seems to be many of but considering how common this seems to be im sure If I installed a second hand one it would start squealing in no time  Or even better if anyone knows how to fix the issue directly with the alternator itself... Any input appreciated Thank you     Link for bxa035 connector picture
    • As above, replace as many as you can afford. If anything, due to old age.
