Hi all, i have a r32 gtst that i have fitted a r33 style rb25det gearbox to. the r33 has a electronic speedo whereas the r32 has a mechanical drive. is there a way around this as the r33 type speedo drive is much longer than the r32 type. is there one out of another car i should be using??

has anyone else performed this conversion?

use red cog off bottom of r33 speedo drive. Get a 32 gtr speedo drive. Cut buff coloured cog off gtr drive, install red r33 cog onto gtr drive. screw in r32 speedo cable.

Done.

Ive done a post in the past, i'll try find a link.

photo below shows red cod of r33 speedo drive installed onto r32 gtr speedo drive on left. On right is std gtr speedo drive.

You can actually buy them from Lincorp Automotive for $100 delivered. The part has the R33 gear for the gear box but uses the R32 speedo drive. They did, however, send me the wrong one, so i had to swap the gear off the R32 speedo drive. Pretty easy to do. Speak to Tim 02 96845777.

Stuff paying that much!

Go get a nissan navara one for $20-25 brand new. Do the exact same thing as Bl4cK32 said, just with a drive that is new, and a lot cheaper! Part number = 32702 - 02G17 pinnion assembly.

If you dont already know you will also need a new clutch slave cyl, you will need the R33 one that matches your gearbox.

Now as I have just saved you money, please forward $25 to my account :P

I am a little confused by this..

In this pic I have a R33 GTST drive at the top and a 32 GTR drive below

the thing that confuses me is that the gears are oriented differently, is this going to work if i swap the drives?

32702 - 02G17 pinnion assembly this part is the same as vl turb it has the wrong number of teeth ex japan from nissan change the 17 on the end to a 21 and there u go now anyone out there find this usefull please send me some cash it took a lot of buying of holden and nissan parts to find this out ah yes i have a r33 turbo bot in my 32 and my speedo works and its bang on accurate 21 tooth std 21 tooth replacement

So can we clarify that the combination of drives i was going to use as in the piccy is not going to work?

They are both 20 tooth

Im interested also!!

Yes, it will work. The R32 speedo drive is on top of the output shaft and the R33 speedo drive is below the output shaft. So the teeth have to be cut for the reverse direction.

:happy: cheers :O

I am also still confused. Neo is saying the part number ending with 17 is incorrect and it needs to end in 21, hence 21 teeth as this number of teeth he says will make it accurate. But what has how many teeth on the end of it got to do with anything as isnt the idea to cut the gear off anyways?

Or have I missed something?

Looking up Nissan part numbers and specs the 32 GTR sender has 20 teeth whereas the 32 GTS4 has 21 teeth. But as I said it dont really matter does it?

Or has Neo not used the 33 cog and installed the Navara 21 tooth sender assembly complete and unmodified? I need to order a sender this week and want to make sure I get what is required. I will give this Lincorp a call as well and see what he has to say.

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
