as topic says, my diff doesnt seem to lock anymore, and under full throttle in second it doesnt accelerate as hard anymore, would it be the diff not putting the power to the ground through both rear wheels ?

thanks

Have u changed the diff oil recently

It will really come down to road surface. Theoretically if the road has the same grip across the surface it shouldnt make much of a difference. It will only start making a difference if one side has a lack of grip then you will spin that side and it wont put power down

I imagine on normal road conditions it shouldnt really make that much of a difference. If your saying it is really noticable you may have another proble. Sure your clutch isnt slipping? even if its only slipping slightly

yea i meant on dry even surfaces, Ididnt change the oil recently, but yea in the wet the car does kick sideways anymore so the diff isnt locking up anymore like it used to

maybe the lack of power is just my engine getting old lol

Hmmm I dunno, my diff is fine and its a 1994 R33 GTST, it still locks both fine.... Perhaps its worth taking out and shimming or at least inspecting

Barring a massive failure like Driveshaft/CV which I'm pretty sure youd notice lol, my only other guess is that the diff has become lazy and you might just be able to re-shim and fix it.... Simple things first but, check the fluid. Mine was a bit funnny when i first got it and i found the fluid was low. Changed it to sme new stuff and it was fine after that

If you want to change it, I use Castrol SAF-XA (or something like that) its relatively cheap and does the job. Id recomend trying that first if it is the diff stuffing up

      Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed

      hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me

      Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.

      You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
