Hi Guys,

I am looking at buying an R32 with an RB25DET. I would like to take the engine out and swap it with an RB25DET for obvious reasons.

I have been told that the brakes are the same on the 1993 R32 RB25DE as the R32 RB20DET, and that only the engine, gearbox will need to be changed.

Can anybody please offer me some information, or advice ASAP as I am looking to buy tomorrow or the next.

Thanks

ok let me get this right, I am sure its typo, so you want to buy a R32 with RB25DET then you want to take RB25DET out and replace with RB25DET... for obvious reasons... :confused: reason would be different engine but same spec?

probably need to change Breaks..... suspension if you have the money, get some new Intercoolers, new engine management ECU...etc.

good luck

Sorry - it was a typo.

It currently has a non turbo 2.5L engine and I would like to replace it with an RB25DET.

The car is a 1993 model and the owner claims that this model has the same brakes as the R32 with a RB20DET which means brakes would not need to be changed.

Thats wrong, brakes are N/A spec, single pot calipers, smaller rotors and a 4 stud hub. So unless the car has been upgraded then the brakes are no different to other N/A skylines. The diff is also different, turbo's came with LSD. Un sure to suspension specs but i am going to asume that the spring etc aren't the same as a turbo spec vehicle. Could be wrong, the weight difference in the models would be fairly similar (1380kg for mine, which is the GTS25) Apparently the intake manifold on the R32 Rb25de is the same as the Rb20det...

Basicly, look at the caliper, the 4pot models are larger and have nissan written on them.

Hope this helped.....

geordie is incorrect.. some non turbos also come with LSD.. and also the same brakes as the turbo. Factory options can mix and match to give anything.

The brakes are probably the same as the rb20det in the latter models on the rb25de's. So you are correct mr r32 in that you'll just have to change the engine.. and the gearbox would probably be recommended but non mandatory to start(the rb20det gearbox will fit behind an rb25det)

predator, you are wrong - my '92 R32 GTS-t, and nearly every other one I've ever seen have had 4 piston brake calipers as standard, not 2....

The caliper I am referring to has the silver NISSAN logo on the front, Sumitomo stamped onto the body, and are the same as used on the Z32 300ZX and the S14 200SX.

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

Yes.. speedo is out of wack..

Its one of the gears in the Gauge cluster.. they used to make cogs to change it to the correct speed.. but these days they are very hard to find..

Your speedo will read over.

There are a few R33 gearbox into R32 threads floating around.. have a look. Off the top of my head it is ia straight fit.

In terms of harness.. there isnt really a hard part.. just swap them over.. as you need to run a 33 ECU anyways..

Best advice I can give you.. look for an R32 and R33 workshop manual for the wiring diagrams..

I have seen a fair few Rb25 into R32 threads in the DIY section of this forum..

      Hr34 fuel pump not turning on

      If you get 12v at one of the relay pins with IGN on, and 12v at another for about 3 sec when you turn the key from ACC to start, then yes you can just earth the relay trigger pin. Just have a look at the top of the relay, it should tell you which pin needs earth when the 12v signal is sent (or if it's not clear, just post the pic and we can work it out). If you always have 12v at 2 pins with IGN on, they it is earth triggered by the ECU which makes it harder to fix (you really need to check the ECU pin is earthing when it should, and if so it is a wiring issue from there to the relay.

      Requirements for Xenon Headlights? (Possible Solution)

      By rahilp · Posted

      Hi There I went through a rabbit hole of reading about Xenon headlights and the ADR regulations for having them installed. As people have been defected by running factory xenon I was researching in ways to make them compliant. Everyone always say needs to be self leveling and have washer installed, which I don't necessarily agree with. For this argument I'm using R34 as reference as I'm more aware on the construction of the headlight compared to the R33 Xenon, which may still be the exact same case.   For the self leveling clause taken from ADR 13 - Installation of Lighting and Light Signalling Devices on other than L-Group Vehicles As you can see the bold text "these manually adjustable devices from driver seats" are fine to use. As Series 1 Xenon model headlights do have a 4 level adjuster on the right near the ignition (however not series 2) then these model are consider compliant in that argument.   For the Self Cleaning aspect of this argument clause taken from ADR 13 - Installation of Lighting and Light Signalling Devices on other than L-Group Vehicles Now i can understand the argument that Xenon will need a washer as they are over 2000 lumens, but I clicked on the 12 at the end of that sentence and it takes me to the end notes which states R34 for headlight lenses are plastic, not sure if PL is mark as I don't currently have my skyline to confirm that marking is there. But could you not technically get a lenses with the PL marking on it and then get away with the argument that you need a washer. I went through a quick read of the adr and might have missed something else that may cause them to be non-complaint.    But wouldn't these technically be complaint headlights   Would love to hear other people input on this and shed some light   Edit In regard to the the washer portion I might be mistaken ADR 45 (which I believe is Regulation NO.45) states 12 cd (candela) I dont understand that portion in regarding to calculating the candela if anyone can shed some light. Otherwise I guess throw in a washer for the headlight and you definitely comply.
