Hi all, I have recently brought an engine (RB25DE) / manual gearbox (small box) from Facebook Market place for a good price which I will be putting into my R34 RB25DE sedan. As you are probably aware the gearbox is an RB20 box which the N/A manuals had. The problem that I'm having is with the boxes sensors. There are 3 ports on the box 2 of which are missing cables I'm not sure if the speed sensor will fit my loom / it looks to be missing a cord? ( On purpose?) And its bracket is broken so a replacement is required. Would my 4 speed automatic one fit? I have attached the photos below including speed sensor Any help would be much appreciated 👍

Hi everyone, I am chasing a set of rb25de pistons, just to be clear NON turbo. I am willing to buy a complete engine/bottom end if the price is right, don't care if all the sensors, accessories, etc have been robbed. If anyone is using am r32 rb25de for a 25/30 conversion, then why not sell me the left overs. I am located in Canberra, ACT. If you are over an hour or so away, then we will need to come to an arrangement with postage. Cheers, Jono.

Hi Guys. So I'm in the process of testing a Sniper NOS kit in my NA 25GT R34. Everything is installed and working, including both the nitrous arming switch and micro switch which is enabled on when foot is to the floor on the accelerator. I've tested it by pulling off the intake and putting my foot down while the NOS is armed and it sprays fine. I went for a test drive last night after completing the setup but when I had my foot down, i didn't feel a noticeable difference (75HP Jets). It felt like the car was starving. Has anyone dealt with nitrous systems before running a stock fuel pump and encountered this issue? I started off testing with the 35HP jets and had a similar issue, so I'm just trying find where the problem is. P.S. anyone have a rough idea how much nitrous a stock RB25DE would be able to handle? I've got aftermarket extractors and a 2.5" cat back exhaust Thanks!

Hi all, I am after a set of Neo Rb25de cams. I have searched the for sale section, but nothing newer than 08/09 could be found. Maybe I'm just a little crap at searching? Anyway, if you have a set bumming around, let me know. Cheers, Jono.

URGENT - Recurring misfiring / stuttering problem with RB25DE engine. Hi to all at SAU Community, I own a 1994 R33 Skyline GST25 automatic with the series 1 RB25DE engine, which is the non-turbo engine. In the seven or so years I have owned the car, it's rarely given me a problem of any sort. I run the car on BP Premium Unleaded 95. In the last 18 months I have started driving the car more often due to work reasons, about 4 times a week, and covering a lot more distance, although most of it is freeway driving. About 2 months ago, I started having a problem with the engine sometimes stuttering and misfiring. It seemed like it was running on 5 cylinders. The spark plugs had been changed a bit over 12 months before that (NGK Platinum plugs) , so it was doubtful it was the plugs, they should last 80,000-100,000 kms, and the car had not even done 20,000 kms in that time. The local mechanic looked at it, could not find anything wrong, just 1-2 plugs needed a clean. He cleaned all the plugs and told me to see how it went for a little while. The car ran like a dream, punchier and more dynamic. All was fine for a while, and now in the last 2 weeks the problem returned, although not as bad as before. It seems to run fine after starting and then idling in park or neutral. Once shifted into drive and idling, or backing in reverse, the problem then appears - misfiring and mild kicking / stuttering. It goes away once back in drive and the car is travelling. It will re-appear when stopping at lights and idling in drive, and also when giving it some throttle while driving, or going up a hill. It all seemed to start after getting fuel at a Shell service station that I had not used before, and only went there out of necessity, so naturally at first I thought it was just bad fuel. The problem continued, so back for another visit to the same mechanic. This time I'm getting told that spark plug no. 3 was rusty, meaning water was getting to it, and that a compression test indicated the beginning stages of a crack in the head gasket between the 2nd and 3rd cylinders. I'm told the car is still drivable, and changing the head gasket was not needed any time soon, but it would gradually get worse. While there, I had a new set of performance ignition coil packs put in, as well as a new fuel filter. No improvement. :s My brother used to be a mechanic, and did his own inspection, and did not find symptoms of a cracked head gasket. Further opinions from 1-2 other retired mechanics agreed. So we are now considering bad advice or dishonesty from the mechanic who worked on the car. My brother poured a bottle of injector cleaner fluid, and also some basic stuff like topping the engine oil, and flushing the radiator with coolant. It actually runs better, but the problem is still there. He is now telling me I should get new spark plugs, especially since I have new coil packs, and to upgrade to Iridium plugs. I am not rushing into buying new plugs just yet, as the current set of Platinum plugs have done a bit over 20,000 kms. Two different suppliers have told me in the last week that they should last 80,000-100,000 kms as said before. MY QUESTION - Has anyone else experienced this or a similar problem, and what could the most likely cause be??? I've heard a range of causes ranging from bad fuel residue, to a cracked head gasket, depending on who you listen to. Any help would be appreciated. Thanks. George.

Rb25de Exhaust Hey Guys, I've got a rb25de swapped s1 r33, would I be able to just buy a exhaust kit for a Rb25de and it would fit on or would I run into problems? P.S I've got no idea what im doing so please use basic language. Thanks,

Hello from Canada! i just recently picked up my first Nissan a 1997 Nissan Stagea with an automatic, RB25de Neo and an r34 Gtr front end, I'm totally in love with it but I parked it the other night and it was running great, went to start it in the morning and it was running rough. I assumed it was a coil pack that died (my Soarer did the same thing last year) so I parked it, and went to the local importer to buy a coil pack. came home went to start the car to pull it into the garage... And nothing. Just cranks but won't fire. Pulled the intake apart to get at the plugs, pulled the plugs out and they were wet, I installed new plugs and still the same problem. Pulled everything back apart and pulled the coils out one by one to check for spark. I turned the CAS by hand to check spark. I have spark on all coils except for cyl 3 ( because of the dead pack) I'm also hearing the injectors clicking so I have pulse also the plugs were wet so fuel is getting to the cylinders. I thought it could be that one coil pack but after searching forums and speaking to RB specialists in town that was ruled out. ive also tried changing the CAS, and I read somewhere that try unplugging the AFM, so I unplugged it and still nothing. I'm at a loss. I'm hoping someone might be able to shed some light on this issue! Thank you in advance for reading! (Sorry for the novel)

WANTED rb25de Hey guys, I need to buy a good rb25de neo ASAP. Preferably in vic - closest to Gippsland if possible.

Hi all, i'm in need to get my timing on my 25DE Neo fixed. Im getting a load of pinging and i'm thinking its to do with the timing, I don't have the gear or time to really get it sorted on my own. So what I was wondering is if anyone has any recommendations to get my timing sorted in auckland? Cheers

( vic) WTB R33 GTS manual gearbox/ starter loom RB25DE Hi all chasing a Manual Gearbox / starter loom for an R33 GTS Rb25de prefer S2, but will take an S1 harness too let me know if anyone has one.

Hey guys I'm having an issue with my monster ? .. My r32 had a rb20de auto in it and the rb20de died. I sourced a cheap s2 rb25de auto from a stagea. Also got a s2 rb25de loom and ecu from an auto stagea as well (grey plug but non neo). Matted 25 to the auto box and put it in the car. I used the stagea loom and ecu and wired water temp, tachometer, fuel pump, ign and constant power where needed. Turn the key dash lights come on, fuel pump primes and turns off then I go to start and NOTHING! Starter motor doesn't even try to start. It's as if the inhibitor is stopping it (e.g in gear and not in park or neutral) Checked relay and it works fine. Checked fuses had one popped replaced it still nothing. Checked starter and it seems fine also. So I'm Wondering where to start looking now as I've been at it for the last week with no progress ( I just want it running!!) Is there a way to bypass the auto system so starter will work? (Tried the manual conversion inhibitor trick that didn't work ). Would I need to make a wire from the neutral switch pin on the ecu to the neutral switch on the auto box to make it start? Any help would be much appreciated. Also thinking of pulling out my ecu and engine loom (r33 s2 loom and ecu) that is in my r32 coupe as my coupe runs and starts 1st pop but it's manual so may run into the same issue.

Hello guys Bough my self an rb25det neo wgnc34 to install on my a31. The engine came with an ecu and everything that is needed to get the car running. The engine is bone stock, i only have modified the exhaust, i have a 3 inch pipe all the way to the back with a magna flow muffler at the end. When the engine was installed the car ran great for 1 week then i started to notice some problems. Bad idle, loss of power, and sometimes the car will surge and would not let me pass 2.5-3 rpm. I changed the maf sensor and added new plugs, that got ride of the surging and the car is now running well, only problem is that its running super rich. The interesting part starts now. I though my car would need a tune and it should run fine. So i started to look at the ecu and the engine and doing research so i can get my self a compatible aftermarket ECU. While doing research i realized the ecu that is currently have on the car belongs to an NA stagea, is that possible? During the first week the car was getting into boost and i was feeling the turbo and hearing it spool and i can feel the car get into boost, is that possible with an NA ecu? Could my car be running rich because it has an ECU that is incorrect? The ecu number is 23713-0v711

Hello everyone so I have a question about the rb25 engine. So in my skyline r34 gtt I have the rb25de neo engine but I want to get it turbocharged. What parts will I need to get for it to work properly?

Hi Guys, I've recently put a R33 RB25DE in my R32 GTS25. All went really smoothly, got it started and sounds amazing at idle. Problem is driving it. Severely lacks power under throttle and runs "spluttery" i guess is the best way to describe it. I've gone through and replaced AFM, coils, fuel pump and filter. No luck. Also checked O2 sensor, TPS and APP. Everything appears to be wired in correctly, no signs of any vacuum leaks, no sunburn fuel coming out exhaust. I am literally clueless as to what the problem might be! Very frustrating!! Please any suggestions or help would be much appreciated :-D

Hey, i have just finished installing a new head gasket for the first time on this engine, i am about to install the intake plenum and air ducting, but i still have these 4 brackets left to attach, im not sure where abouts they go, and i dont want to put the plenum on before putting the brackets on, if someone could point me in the right direction that would be helpful, if possible could someone post pics?

Hey new to the site but love this place for information its helped with my other skyline (R32 coupe with s2 Rb25de from a r33. Used s2 loom and ecu) . But I'm stuck with this problem any ideas guys as my head is sore from over thinking. Pic of the coupe

Hey guys first time posting here, I've been having this problem for a couple months now, just want some advice or someone may have had the same trouble. Also been to a few mechanics and shops but still unsure on what the problem is. Basically the engine randomly misfires while I'm driving at pretty much any rev and any gear, the engine light will come on, and basically keeps stuttering for as long as I stay around the same revs, unless I take the foot off the accelerator then it'll come good again. This can happen as soon as i take it out of the garage or after coming home from a long drive. The codes were telling me MAF and airflow originally so i replaced that, the other possibility was the coil packs might be on their way out so i tested them with a multi-meter and nothing seemed too out of the ordinary. Also changed the spark plugs just to rule out that problem but its still happening. Any thoughts or leads? Cheers.

R34 Gt 25det install Hi Guys, New to the forum but have not had much luck elsewhere.

R32 GTS Rb25de stock air cleaner setup Hi all, I have a R32 GTS Rb25de that needs to go through a NSW EPA inspection. The issue was excessive noise, which has been corrected with a new muffler. But I also need to refit all the stock emission control stuff. I've done everything except removing the pod filter and reinstalling the original air cleaner. This was already off the car when I bought it. I got a box of bits with the car but I'm not sure everything is there. My question is can anyone supply a photo or diagram of how the stock air cleaner, ducting and hoses that go to and from it should look. Thank in advance.
