R32 GTR vs R33 GTR Speed Sensor

Hi Guys,

Purchased a R32gtr gearbox with osgiken gearset and upgraded transfer case clutch plate, going to be installed onto a R33 gtr. The speed sensor from R33 is electric (which I need to retain) whereas the R32 is cable. When I pulled both off the gearbox, R32 red cog/pinion has 20 teeth and the R33 white cog/pinion has 19 teeth.

Read somewhere that you can straight swap them, though the pinion being smaller in the R33, as the shaft is offset and can still mesh correctly?

Can someone verify?

 

TIA

Bumping an old thread as I’ve had some trouble finding the information I need. I have a late model R32 GTR(back of cluster is blue, not brown) and I’m running the Haltech Pro plugin. I would like to use the Racepak IQ3 logger but I need a speedometer solution.

 

Can the R33 speed sensor be installed in the R32 without modification? If not, what other options do I have?

 

Thank you in advance.

I'm assuming you intend to remove the original dash then? If not (I haven't) the orginal dash provides the speed signal to ECU then to IQ3

I can't answer the speedo drive question for sure. I'm surprised the 32 and 33 ones are different as per the first post.

The speedo sensors are interchangeable as the 32 vs 33 speedo drive gear within the transfer cases are the same.

Ages ago I thought the transfers were actually different because of this but they are not.

Thank you guys. I had intended to gut an OEM cluster to mount the racepak but I could always just pull the lights from the OEM cluster so it doesn't distract me and run the racepak in front of it. 

 

I do have a friend with a full R33 drivetrain so I could always try the R33 sensor to confirm that it will go right in without issue.

      Should I use rust converter on this?

      The easiest option might be to just spray a bunch of fish oil in there.  At least that way you can feel like you've done something while you continue to ignore it

      I'm firmly on the "zero compliance is good compliance" for FUCAs. I'd be looking to solid metal joints even if the primary reason for having them is because they facilitate the twist in the arm. I have never been more happy with the way the front suspension behaves than I have since I got rid of the FUCA bushes. Even the thin little (short lived) poly bushes in the Whiteline adjustables have too much compliance for my liking. It probably won't be long before I have sphericals nearly everywhere, probably including both top and bottom arms in the rear, and I'll start complaining about the increased costs for dental work. But I will be enjoying the driving more, I'm sure.

      I have offset Nismo brackets so the fact the gktechs can pivot is less important to me. I have 170mm JIC arms with bushings - but they provide no adjustment and I'm not sure whiteline eccentric bushings will fit them (I don't want to ruin the bushings currently in them to find out). Ideally I want something with bushings + adjustment; hence why I'd like to find a pair of these. Unfortunately they aren't easy to find.

      @Vee37 How much do you really care about finding these pads again? If your pads are quiet, work well and produce minimal dust, really isn't that enough? If you are set on finding the exact pads again, I suppose I'd do something like this -  Visit your local Jax, find out what brand of pads they carry. If the Jax workshop you previously went to had the pads on the shelf, then you can almost guarantee it will be of said brand.   I'm guessing you don't have the receipt for the previous work and pads. Can you visit a Jax workshop and see if they can look up your previous job to see what pads were fitted?  Still no luck? Put your stalker hat on, find the staff that used to work at the Jax store and ask them. Talk to local workshops, try to find out where the mechanics went to. Talk to Jax workshops, maybe they relocated to another workshop. When it comes to mechanics, its a small world. You'd be surprised how easy it is to track someone down. If these ideas don't work, shit will start getting crazy very quickly.... You could find out every brand and model of pad that fits that car... and try them individually ticking each off the list if it wasn't the one you were looking for.... If you go down this path your going to want to learn how to swap pads yourself, it is very easy, takes minimal tools and space. If you have room to park the car you have room to swap the pads. Plus you have the advantage of making sure all the brake hardware goes back in so they won't squeal!
