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.

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?
