No doubt SAU has a few threads about this but can't find them and google just finds me 25 box into auto 32 etc etc

Usual thing happened, blew the rb20det gearbox drifting and want the rb25 box for the usual reasons.

This is what I know......

1. 25 yoke welded on the 32 tail shaft

2. Closs member fix (not 100% sure what needs doing)

3. Navara speed sensor (again, not 100% sure what needs doing)

Any info would be good and pics of what needs doing would be even better. Car has a 2530 so not sure if that'd make a difference.

Please no stupid comments or remarks

Thanks in advance.........Fliggy

Yuh, but that wasn't his question.

I had to swap crossmember when I did RB20 manual into auto R32. Then when I did RB25DET manual into the same car, I had to change crossmember again. I don't know for sure, but I strongly suspect I ended up with my original auto crossmember back in the car!

Fliggy, if you want someone to build a Navara sender up for you, contact Fours N More at Pooraka. They have done heaps of them. I suspect that they probably need at least some of either your R32 one or the R33 one. Apparenly it's not particularly hard, but I didn't pay any attention when it was being done to mine as I was either busy on some other part of the car or away overseas (I can't remember now, too long ago).

Otherwise, your list is about all the tricks involved. Take measurements of the lengths from the back of the new gearbox to the centrebearing studs on the car, and take your R32 tailshaft and the front half of the R33 one to Spicers and they'll cut and shut it for you. They do so many of them that if you walk in with the pieces they will recognise them and you won't even have to tell that what you want done.

Make sure you have the correct slave cylinder too, as they are different between R32 and R33.

Sorry to bring up an old thread but don't want to start a new one as I feel this has been answered but I cant find it.

I have an r32 manual with rb20det and box.
I also have just obtained a r34 RB25DET Neo with manual box flywheel everything as it came from the R34.

I want to put the 25 in the R32.... obviously

Is there anything I need to be aware of with the gearbox?
I just want to get all the parts I need before hand to make it as easy as possible.

Thanks

I had Neo and Neo box in my car. No different that fitting a standard RB25 box Into a 32.

RB20 box is 800mm long

RB25 box is 780mm long

RB25 box also had a different yoke to RB20. It's the same as 300ZX/VL turbo box. You need to acquire a yoke and then get it fitted to your RB20 tailshaft. You don't need to extend or shorten the shaft, keep it the same length.

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
