Hi.

The right rear end.. From what car is it? I am very confused about it. It shuld be from an R32 GTR.

But on the disc it says RB25... Hand written. Like a tag.

Diff ratio, if turning on the diff side, i get ~3,6 revolution on the wheel.

Hope someone can help me, as in building 4wd on my s13, and need to be sure the front and rear diff ratios are the same.

Hope to get some quick help as om going to buy the front stuff tommorrow...

Thanks

Looks absolutely like an R32 era rear end. The upper arms definitely. 6 bolt half shafts and CV joint type tailshaft connection make it a GTR diff. Also has ABS, whish wasn't so common on other non-GTR R32 era stuff.

3.6 diff ratio is not right. GTRs are 4.11. Could have had a different centre put in it.

The diff ratio is 3.6....

The way I meassure diff ratio is by putting marks on shafts and turning either the disc, or the input shaft on the diff.. I get the same result of 3,6 ratio.

The 4,11 is not a final drive ratio?

But thank you very much for the reply.

You should be able to tell if it's from a Z32. The diff is an R230, which is noticeably larger than the R200 from Skylines and GTRs. I don't know about the diff ratio for theZ32, but because it was a bigger engine it could easily have used a taller ratio, and 3.6 would be a good choice.

      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.
