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?

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.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
