The a31 efi m/t gauge cluster is so hard to find in my country as all cefiro models that were released here are carbed with an rb24s. A friend of mine fitted an s14 gauge cluster and it looks very seam to the shape of the dashboard except that its a little smaller. The r32 gauge is the only one I can find here that is why I am asking but if there is a way to make my stock non-efi gauge to work with an efi engine then that would be good. Any help would be appreciated. Thank you.

Hey, can u post ur friend's s14 cluster ?

Also u don't need to swap the whole cluster to make it work. Just get an AT rb20de cluster and take a tacho from it and put inside ur rb24 one. I did this already :rofl: If u use rhd cluster, ur speedo will be on the wrong side. And this complicates things, u would have to do something with the speedo cable and do something about the mounting brackets for the cluster in the front dash.

Sure, I'll take a pic of my friends s14 cluster when I see his car later since its undergoing some works.

Thanks for the info. I'll see if I can find any rb20de gauge cluster. :rofl: Do you think any speed from the cluster of other rb20d engines will work too?

You can swap the dials. But u don't need to swap the cluster itself. U can have the 180km/h dials if u like and have the old mechanism inside. Btw, you can also use your old rb24s gearbox for the ease of conversion. Its the same as turbo rb20det one. Has same part number, red breather hose. Can you PM me ? Wanna ask you some questions about how you do conversions there.

Thanks!

Any cefiro tacho should work, besides the RB24S. That leaves a few more options, RB20E, RB25DE, RB20DET. Manual or auto doesn't make a difference.

Interested about the S14 cluster sortof fitting, would be good for people who do SR conversions, both the tacho and speedo would suit engine/gbox conversion.

sorry for the crappy pics but here are some pics of an r33 gauge cluster in an a31. If they are the same then the r32 cluster will fit too. I'll try to take pics of my friends s14 gauge in an a31 for the benefit of those who wants to use it.

Hella Flush,

Some wires on the cluster sockets were rewired.

daisu,

From the setup done to the cefiro with the r33 cluster, everything from the r32 speedo sensors were used since the engine my friend got came very complete with all those.

Digging up this old thread.

My cluster is playing funny business so this could be a nice little mod. I'm thinking that the engine is RB25 so the tacho should be ok. Box is RB25 so technically the speedo should be ok too. Not sure about the other gauges on there though....

Can anyone shed some light?

    • 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. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
