Felt that on the way back. the car skits heavily to one side. He did mention about welding them together. or not sure if there is any one whom can modify stock diff to make them stronger. Alternatively I was thinking buying a kaaz diff. not sure which one is better to get 1.5 or 2 way? It is a road car and I do drive a fare distance testing new turbos, I still want it to handle smoothly on road.

1 way diff tightens on acceleration, 1.5 way tightens on acceleration and 50% on decel, and 2 way tightens on acceleration and deceleration. So unless you plan on drifting the car, no need to have a diff that locks fully on decel.

I don't drift this car. its mainly for street, and will be on quarters often now. I'm planing to drop in a set of pon cames and pumping it to about 450rwkws mark. Sorry I'm really a noob when comes on the diff. I will likely be buying a kaaz diff, So which one better for my application? the 1 way, 1.5 or 2 way.

Do Kaaz make a 1 way diff? If you're gonna stick with 1 way, just re shim the stock diff. Otherwise 1.5 way will be more than enough, a 2 way won't help you on the strip.

Hmm, after a bit of reading I gather shimming is much like welding, and effectively makes the diff a 2 way. Hadn't realised this. I'd just go for a stronger 1 way if anyone does them, otherwise a 1.5 way.

I know plenty of people who have run shimmed diffs for year with no problems. How long the shims last is dependant on the size you put in. That said they aren't running down the strip with 400kw on a set of sticky MT's.

Would someone slap me over the head. This whole time I've been saying 2 way when I actually meant 1 way or 1.5 way. Been having blonde moments of late haha.

I've uploaded footages for all good runs out of the day.

There are number of interesting cars there yesterday, I will publish the video after further uploading completes.

Don't shim the diff.

I put a .8mm shim in mine and its disgustingly tight... But the sad part if its just meshing the spider gears together, and making it jam at low speeds. The actual LSD coupling has little to no ability to be preloaded in the grand scheme of things. A pointless mod causing only discomfort IMHO.

Me? No.

Still got the shimmed diff which feels uber tight when you're cruising and has more or less the same LSD effect it had prior when you jump on it.

shimming was my first suggestion or 2-way / welding.

It needs some cradle locks too as the tramp was bad enough to knock it out of gear on numerous occasions.

i reckon a line lock would also allow better warm up burnout as the car labors too much in 2nd with the MT's

i will wire up the clutch switch so we can dial in some retard on the line and produce a bit of boost..

when you put 3+mm of total shim in there you need to add a thicker backlash shim/washer, mine has a bit of backlash play at low speeds as i still havent sorted that out. although mine is pretty much a shimmed locker so by fair the most cheap and reliable set up over a grenade of a weldy

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
