I want to buy a cf drive/prop shaft for my car from the current group buy,

Only my car is an R32 GTSt which will be running a R33 gearbox and normal rear end.

I figure since i need to mod the prop shaft i may as well get a new one. So does anyone know from their RB25 gearbox conversion whether the shaft length is any different? Shorter, longer? Or is it just different connections?

Hmm. probably need to just wait and confirm length of tailshaft whenever the 20 box blows

Sorry to bring up old thread, Roy did you ever end up putting the 25 box in your r32? Just wondering how did you solve the speedo sender problem if you have? Been doing my head in figuring out where to get the bits from in melbourne, having a little trouble tracking down a Navara speedo sender (dont know what year Navara and being told no longer stocked by others), i am not too confident with cutting and shuting bits and pieces to come up with a reliable solution, would much prefer a drop in option even if it is a bit more. You reckon you could throw any leads my way?? Cheers

You can get away with just dropping a Navara sender straight in if you have taller diff gears..

I put 3.9s in mine and the 17T Navara sender resulted in my speedo reading 7kmh high, perfectly fine as far as I'm concerned :blink:

If you don't have any luck finding a part number, shoot me a PM, I think I've still got the box at home somewhere.

Playing with the sender myself at the moment. Got a navara sender and chopped off the gear as I have a 4.3 diff.

Pulled the cog from the 33 box and now not sure what way to go about attaching the 33 cog to the navara shaft?

The 33 senders cog was just attached with a circlip and the navara cog was moulded on meaning the shaft from the navara sender is full circle whereas the shaft from the 33 sender was alkf moon on the end.

So...I'm left with a cog thats half moon through the centre that needs to be attached to a full circle shaft. The cogs from the 33 are no longer available so dont want to muck it up. How have other people gone about it? My best thought was to get a dremel and small grinding stone and slowly chop it away?

I have posted the solution to this problem so many times I've lost count.

Some others here have slowly caught on.

If you can't be bothered searching get a sharp round file and carefully make the half moon in the 33 cog perfectly round.

It will be a nice press fit onto the navara splined shaft and shouldn't need glue.

Don't forget to recut the location slot on the navara speedo drive 180 degrees opposite the original slot or it will only last a short while.

Touche mate.

I ended up searching and found the answers...many times over lol. I think I may go with grinding down the navara shaft though. Coz if I stuff up I can get another one. I also found that the R32 GTS4 has a 21 tooth cog. Cant find out which way the teeth are cut though....

    • I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.
    • One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
    • I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.  
    • Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.
    • Yep that is correct. It allows you to adjust the short throw range from what I can tell
