Rear Diff. LSD???

Pretty much impossible to tell from a photo, but the finned cover suggests it might be a viscous LSD. Try jacking up the rear end (both wheels off the ground), then turning one wheel - if the other wheel turns in the same direction, then you have an LSD, but if it turns in the opposite direction it is an open diff (probably - i've seen completely stuffed LSD's act in the same way as an open diff).

RC45 says you have an R200 diff with 4.5 gears.

I jack the car up last week and when i turn 1 wheel front or back. The other doesn't move at all. Is it spoiled?

Where can i find info on how to tell what type of LSD i have and if it is damaged or worn?

Turning a wheel while your car is on a car may not cause the other to turn as well for both an open wheeler and LSD - the other wheel will only turn definately if you have a Locked diff.

The 4.5:1 is better for fast pick up and drifting although you'll go thru fuel way quicker.

One way of telling (the way I found out at least) is to go to a quiet road and do a long 2nd gear burnout (dumping the clutch hard so as not to allow it to slip) - do the burnout for about 5 metres and get out and check - if there's 2 black lines, it's working if there's only one, then it's broken or it's an open wheeler.

If the LSD is working (at all) both wheels should turn together....on an open diff they will turn in the opposite direction because that is the nature of the mechanism. The ONLY way this won't happen (either case) is when something else is preventing it (eg brake pad drag).

      S1 rb25/s14 starting problem

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      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.
