Hey all,

I bought my cefiro about 3weeks ago. The bloke i bought it off installed the 20det motor himself from an R32. He said the temp gauge, rev tacho and window wipers all worked before the install and didnt after..

i just picked the car up from a mechanics who said it was the fact that the cluster is original from when it was non-turbo and signal sent from the turbo motor is different and the cluster cant read it properly. The temp gauge just goes straight up to 2/5 full and stays there and the rev tacho doesn't even flinch... He said if i get a cluster from a factory turbo ceffy it will fix the problem.. Same with the wipers, similar story but he said you could prob just get and auto elec to just re-wire it..

So im just after someone who has encountered the same problem and what they had to do to fix it, so i don't go wasting my money.

I'm thinkin of ringing some mechanics that do engine conversion on jap cars and ask if there've done many 20det conversions into ceffys and see if there've had similar problems and what do to fix it..

I've had a few mazda, previously but this is my first RB so im abit of a noob. Any help would be awesme.

Cheers jared

Hey champ, just put a r32 rb20det into my cefiro. You'll find the plugs that connect engine loom to body loom are different between r32 and cefiro. It's not the cluster, but where the wires go in the plugs. Basically need to identify tacho, temp gauge, wipers wires on cefiro plug, then identify on engine (r32) loom, join up. I was looking everywhere for the info, ended up getting a mate to help out. Can have a look and post the info up, prob on weekend. Where you at?

Just out of curiosity, what ecu are you running?? Mine is running an A31 ecu with an 32 RB20 in it.

Also wanted to know if anyone has any pics they wouldnt mind posting up on where the ecu is installed. Cause mine is just lying on the passenger floor and i wanna know where it goes and which way it faces..??

Hope someonecan help. Cheers

It won't be the cluster at fault.

If you look at where the ECU is there should be a plug coming from under the dash board, you will need to find some wiring pinouts to identify the correct wires. Then you will find a plug coming off the ECU loom will have all the dash wires in it but the plug will be different shape. If you have the original cefiro loom you can chop the plug off and pop the wires in it, otherwise you will probably have to join them with solder or some other connectors.

As far as the ECU location, it is supposed to sit behind a plastic kick panel on the leftside of the passenger footwell.

Thanks for the reply, yeah i know now it def isnt the cluster... I may have to get some pics up cause where the ecu is their is about 4 other plugs not connected to anywhere. 1 or 2 of em im led to believe had to do with it being auto before... The others im not sure...

So you reckon i need to get the cluster out, check the wires that run to those gauge that dont work and then identify them at the loom end??

      Hey was wondering if you ended up installing the R33 GTR speed sensor - I found one too and wanted to confirm it's a direct swap into the R34 6 speed?

      I need more than help to finish my R33

      By marni · Posted

      Hi all,   I’ve got the biggest lot of problems with my R33 GTS-T   It was a freshly rebuilt 25th anniversary RB25DET (plastic cas, neo cams) probably 6 years ago now   The engine was running so well but I fkd up badly and trusted someone I’d known for 10 years that was well known around Plazmaman for his welding and fab work. I added a lovely photo of some of his previous work. Not sure why my car was worked on by whoever did this shit     I’m normally someone who would never open myself up to something like this, I still can’t believe I did it. Trusting him literally fkd it all up for me. Everything has been a struggle, like it’s almost been 6 years that’s how much I’ve just on and off been trying to work it all out.    All I wanted was a car that danced down low, like full boost from around 3~3500rpm to redline, don’t really care what power it puts down (if it ever does) but I just wanted it to be quick to get on it.    He recommended the turbo to get, I picked Hypergear but he told me to get the front 4” with a T4 and 0.68 rear housing.    I was expecting all these beautiful welds, tidy fab work and paid for it to be ready to go to a tuner when I got it back.    I got a car back that was an absolute mess, I actually couldn’t believe it was my car anymore. I don’t think you could even call what he did welds, they’re disgusting.    So I stripped everything he touched off it and with every bolt I loosened it just got worse and worse.    I covered it and literally built and finished another car in the meantime but now it’s getting to the point where I really want my Skyline back.   Its a struggle because I paid him to do all this shit because I didn’t know how to and now I’ve had to try and figure it all out omg    Please excuse the bird shit horrible welds, I’ve got my show pony car and am so beyond dealing with this car I don’t even really care at this point.    If someone told me about what he did to my car I wouldn’t have believed them but it happened to me. It was unbelievable. He went missing, my car went missing, it came back missing parts, the straight af chassis rails bore the scars of being dragged up a trailer backwards, even the sandwich plate was bent. Everything was leaking and open to whatever fell into it, rounded off/ missing bolts, power steering oil and coolant everywhere, no gaskets, parts stolen off it, even managed to damage the sump pan.   Promised me he’d finish the car, knew what it meant to me, I paid him thousands and thousands just for him to trash it. He told me he was fully licensed and insured, come to find out he’d cancelled his ABN, so obviously no insurance. I had laid up insurance on the car and would’ve been covered but I was scared they would’ve written it off or because the business was no longer trading I’d still be liable.    He was supposed to:  New fully custom mild steam pipe exhaust manifold with turbo location moved from factory position to high forward mount. (I don’t know if it is a mild steam pipe, I’ve got a funny feeling the waste gate isn’t in a very good position and I don’t think the outlets off each cylinder are equal) 4” custom stainless steel dump with external gate (he re-plumbed it) Cut and shut OEM intake manifold with throttle reposition (I ended up doing the throttle reposition) Box in pod filter (left out) New 100cel catalytic converter (pretty sure it’s there but unsure if it’s 100cel) Front mount intercooler piping fabricated to suit (all smashed up and rusty holes where he was supposed to make it look standard where fmic piping passes through. I don’t even think my front bar is going to fit 🙄) Custom 5” intake pipe from pod to turbo (didn’t come with it so had to do something to make it work with the Z32 afm)   Engine: Full cylinder head service & machining  Brand new valves Precision upgraded spring kit Engine block honed New bearings  New piston rings  New ARP conrod bolt kit New ARP head studs Cometic head gasket VRS kit   ATR43SS2 ball bearing turbo 0.68 rear housing  Turbosmart 45mm external wastegate (got delivered to the fab bloke, I’ve got no idea what spring is in it, I’m assuming the one that came pre installed) Walbro 260 fuel pump  Nismo 740cc injectors (tested to 880) Spitfire coil packs GCG FMIC RB25DET manual 5 speed 4:11 rear diff   I’ve got an Apexi Power FC in it atm, I was hoping to just get it to operating temp to make sure everything was okay before towing to a tuner but it’s over-fuelling too much. I don’t think that’s going to happen so i think I’m going to get either a Link G4 or Haltech for it. What do you guys recommend? I can’t work out the power FC so just gonna give up on that one     It’s got an exhaust leak coming from somewhere I can’t see 🙄    The fuel pressure was steady but now it like drops from 40 to 20psi randomly (noticed this yesterday)    I’ll attach pics of the shit he put on my car and the engine bay now as it sits    I really just need some help, I need a tuner in Sydney I can trust, I’d like to be with the car while it’s being tuned if possible, I know it looks terrible but unfortunately I’ve just got to put up with it for now and fix the cosmetic stuff later   Do you guys think the manifolds are going to be okay? Or do I throw the exhaust manifold and try again?   I don’t even think these combinations are going to work tbh   I know everything I fitted was rated to be able to take at least 400kW but most rated higher    If you’ve gotten this far I really really appreciate it 🙏 I don’t mind if you trash me or the car, I made a rookie error and f**k I’ve paid for it. As you’ll see 🙄
