Hey yeah It's a viscous type diff. I was hoping to ad the extra plates thu never came with to make it last longer.

I'll try Nissan cheers

Why don't shim it? Got Afew things to buy so just was fix this diff up for the minute.

Cheers

If your diff is a viscous one, do not "shim" it. Abandon the idea as a bad one. Save up for a real diff. If your diff is a mechanical one, why don't you contact a diff workshop? Yellow pages.

Or if your diff housing permits, drop in a R34 or S15 Torsen diff. Practically zero maintenance as it does not utilise clutch plates as mechanic diffs use. However does behave a like an open diff when 1x wheel is off the ground.

Everyone who has said "I shimmed my viscous diff and made it great" is ignoring the fact that you CANNOT shim the bit that matters. The bit that matters is the viscous cartridge. It's sealed up. You put shims on the outside and all you do is add pre-load and wear in places where it isn't supposed to have it.

Viscous diffs are great in low powered FWDs, and maybe in stock low powered Skylines for a few years. But they're not worth playing with as a serious option for anything else.

I'm doing this right now. S15 centre into R32 housing (with 4.11 gears added). It's at the diff shop getting the CW&P set up today.

Only trouble with using S15 centre is getting S15 3x2 bolt half shafts (have to use the shafts that suit the helical centre because the normal ones don't fit). So I had to get some S15 driveshafts too. At least if you get R34 helical you get all Skyline style stuff. But I couldn't find one for sale that I could be sure was helical. I bought one, but turned out to be viscous.

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      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

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      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.

      Looking for someone with a R34 front bar

      By DraftySquash · Posted

      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. 😂

      new 1.5 LSD issues/concerns

      By Dose Pipe Sutututu · Posted

      Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
