ok so here it goes:

*cars a s13 with a rb20 in it, all wiring is fine to the ecu and such, there were problems but all fixed!

*so i currently have no speedo or reverse lights, i did have the rpm but i tried to install a tacho in, by using the yellow wire with red stripe, still tacho did not work, and when i reconnected the wires together the way i found them, the rpm meter wont move now???? FFS argh

car currently has the ca18de electric instrument cluster, will i need to get a r32 one + the cable wires so it all works? will the cluster bolt straight in?

any help would be absolutely helpful as the other forums i posted the same question in, did not help 1 bit

thanks all!!!

If youre running rb20 ecu ca18 cluster will not work. You need rb20 cluster. Mate has R31 skyline with dodgy cluster we tried pintara cluster which look almost completely identical, plug in and readings are out of wack.

Good luck.

mate for starters the original tacho will never work with the rb20 computer as the signal is different. secondly i'm pretty sure the s13 came out with a transducer type speedo where the r32 comes out with a cable driven speedo. the reverse lights don't work because they're not hooked up or fuse could be blown.

i am about to aquire a silvia with the same problem has rb20det in the s13 which is runnning a ca18 dash, the speedo works apparently but that is it...i was going to try find a rb20pin out diagram for the ecu and try match it to the wires off the back of the ca18 cluster..this won't work? if not like the original post said..will an r32 dash bolt in? cheers, Hame.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
