Diff is open wheeling, time for a shim to tighten it back up :P

which motorkhana was it, i really want to get into some of these.

Yeah time for a him, you can get them from nissan for like $5, there is an excellent write up here about it.

I am going to do mine sometime soon i hope, along with about 30 other jobs. LOL

i would just like to mention that i have shimed my diff up before and it isnt realy as easy as said it is ment to be. i havent looked at the thread that you put up wogs but you do need a few basic tools and more than a shim. the biggest problem i had is that mine was to tight, much like a welldy and it made my car gay to drive :unsure: but if you get the right shim than you will be fine. i will also add that shimming the diff cost around $50 compared to at least $1000 for a locker it is a good option and i will be doing it again but a bit more reasearch will be put in.

oh and get yourself a lock bar

the motorkhana was for the msct at archers manour ,as for shiming the diff i have looked at the thread in sau drive line and transmissions ,the thing being i am still only fixing up an old lsd with aims of doing lots more motorkhanas and other events and dont want to be having to shim it up on a regular basis ,so i would like to maybe find something a bit stronger but still qiute drivable on the road not something that will spin me around as soon as it rains :unsure:

buy a new centre then with a mechanical lsd, it will be pricey, but better in the long run. if your single spinning now, shimming it won't help much.

You can really only shim a diff if its in good order to begin with. if you try and shim a worn diff it will be the same if not worse pretty quick.

well the cheap way is to shim it, r33 diffs seem to lock easy (yes i tried it out on mine but didnt like it because im pretty gentle on my car), im betting a shimmed up 33 vlsd would last a couple years because when i pulled the shim out of mine it still worked the same as before i put it in. if you dont mind your diff being virtually locked under 40kmh then id go for a 1.0mm shim, if you dont want it locked go for a smaller one, it does work well and for alot cheaper than a mech lsd. saying that a mech 1.5 would be your ultimate, perhaps shim it while you save for the 1.5 way?

Hay toffy, so if i put in a say .9mm shimm, what would that give me?

a locker mate, its not worth it imo unless its for a track pig, if i were you id look for a nismo 1.5way, these are awesome for someone as pedantic as you (meant in a nice way), they act like a std diff untill you dont want them too

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
