Guess it wasnt such a simple question as I cant find the info anywhere. Got someone to crawl under there car and they couldnt see a part number either.

Nissan gearboxes don't have any PN's anywhere on them. When I get the chance to boot up FAST I'll get some PN's for you.

That would explain why I have had enormous trouble trying to find out the number and why the person who crawled under there car for me couldnt see anything.

But from memory, I beleive the rb20 boxes actually have a number on them so I thought the rb25s would as well.

The only reason I wanted this part number is because I am looking for a RB25 box as my 20 box died and if I go to look at one or whatever I want to be able to know it is the correct part.

Only info I have is that the rb25 box is a lot larger than the rb20 one. But the 33/34s also had NA manuals so what boxes where behind them? Obviously weaker than the turbo variant but are they visualy the same as the turbo box from outside or look like the RB20 boxes? Then theres the MX7 from VLT that also can bolt up so I dont want to be confused.

In a nutshell I want a way of being 100% certain as to identifying the 25 box? And also a way of telling R33 from R34.

Not so sure but from memory i did rang up nissan n they told me that the 33 and 34 have the same part number for the box but some internals were different part numbers so go ring them up n double check... good luck mate...

The R33 NA box is physically the same size and strength as the RB20 turbo type (which is essentially the same as the RB30E type). Haven't seen an R34 NA type but would be surprised if it wasn't more-or-less the same as the R33 NA.

The MX7 looks very similar to the R33 turbo 'box, but has a mechanical speedo drive which is pretty easy to spot.

Someone posted side-by-side pictures of the R33 turbo 'box with the RB20 type in another thread, so perhaps do a search.

It's true the RB20 and RB30E gearboxes have some markings on them but they aren't PN's. Even if I gave you the PN's I doubt it's going to help much.

Jayson, you should be able to move RB20DET/R33 NA boxes yourself as they are not that heavy.

The RB25 box however you will have great trouble moving alone as the weight of the box is huge compared to its smaller brothers.

I always need a hand moving my 25 box around because im no beefcake :)

I think R31_POWER or similar posted comparison picks... it was a while ago now and i cant remember what thread :)

The R34 box is pretty much the same inside as the R33 box but is much lighter. I can pick it up easily. It has a more raw aluminium look to the casing.

The manual says that the R34 turbo box is FS5R30A. The R34 non turbo box is FS5W71C.

    • Dredgggggeeee time; I have recently finally started driving the car. It sat for so long that the fuel tank gave birth to rust sludge and blocked my lift pump sock and one of my walbro 460's and left grime, rust chunks and muck all through the surge tank and system. I decided to commit and pull the trigger on an oem r32 gtr fuel tank and Frenchys twin 460 / sender / surge tank hanger combo and all new larger lines and fittings etc, also boost doc heater hose kit / new heater core and a heap of other bits and shits like wideband sensor installed in the dump and Syltech iacv + lines and all wired and added to current tune. now having lightly driven it a couple times without issue, I can happily report on the hta3076 in its current tune. still no boost control switched on, 20psi gate springs, car makes 22psi at 3200rpm in 6th gear with 30-50% TPS from cruise at 100kmh. Going by the old graph, this means it should be making 300-325whp at the same numbers above. Very very responsive setup under true road driving loads. all that's left for the build is body loom + PDM, finish the remote aircon setup, install carbon fibre parts and go for full tune and 30psi. the 315 rear tyres are now performing like they're 195's, wheel spin in any gear at almost any rpm, whereas my previous setup hooked up in 3rd no issue, albeit Nt01's back then / RB25 5spd vs (new) old date r888r's Z34 6spd now, + obviously all the support upgrades I listed in the quoted post above. car sits at 1-3psi on cruise at 100kmh, expectations totally exceeded and I'm beyond stoked with all this so far.

    • I've also been eyeing their rear axles for my car. I purchased seat mounts from them about 7 years ago and they were hot garbage so I've been a little wary about purchasing them. With that being said, please buy them and get back to us haha. 
    • Can a moderator please move this into the right category.. I've accidently put this into racing build thread 🤦🏽‍♂️
    • Being a manual, we very quickly ordered new R34 gearbox (From Nissan) and remaining parts from Kudos motorsports. Would highly recommend the team there. Ultra helpful and quick to share advice and upgrades. We are in the middle of taking the Auto out (Genuine 94,000/kms) and putting the Manual in this weekend. Part 2 of the build will include likely a Plazaman Intercooler and Plenium, Hks Exhaust with Tomei Dump (ordered).
