Can anyone tell me about the LSD's in an R33 GTS-25T? I have read that the manual cars come standard with an LSD, however after fitting new coilovers recently I've found that if one of the rear wheels lifts up such as when going up a steep driveway the wheel without contact spins endlessly without the LSD ever engaging. Is my LSD worn or how can I tell if I actually have 1???

Cheers

There MAY be a small tab on the rear of the housing with "LSD oil only" written on it, or something like that.

Alternatively you can jack up the rear end of your car.....spin ONE wheel and if the other wheel spins in the SAME direction it is LSD, if it spins in the OPPOSITE direction it is open diff.

To check the condition of it have a mate hold one wheel while you spin the other, if there is little or no resistance then it is basically stuffed........of there is reasonable resistance you have a decent lsd.

Hope that helps

Viscous LSD's don't immediately lock when one wheel is spinning, they come on gradually as the viscous fluid heats up. You can only really test their action after you have been driving (and using the limited slip) for a while. ie; don't walk out in the morning jack the car up and expect to get a satisfactory result.:P

i think its time you invested into 2way or 1.5way lsd, its diffinately worth while!

We ran one of ours as a BOC locker on the weekend, while we wait for a proper one to arrive from Nippon.

Worked a treat...

There are only 3 types of viscos LSD, 1. New ones, 2. Ones that don't work, 3. Welded ones.

Should be able to score yourself one for round $700 S/H

TT

Jase, when i had my factory viscous lsd and super hard tein coilovers, id also spin one wheel real easy while going slowly through driveways. In my case the suspension was so stiff that when going through a driveway angle one of the rear wheels just lifts off the ground, allowing it to spin, and i would never feel an "lsd effect" in these conditions. Launching however my lsd would work fine. Do a burnout, and id have two nice black lines.

As mentioned its easy to test, after a good drive give it some boot off the line and check your tire marks on the road.

    • So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic
    • If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.
    • LOL, all of the CAI like Craig I just need to put a hole saw through my bumper Done and dusted, the car runs, which is nice, I'll take it for a spin when the weather clears up Just need to put the bumper back on for good

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
