LSD woes

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.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
