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.

      S1 rb25/s14 starting problem

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
