After I get the differential stuff sorted out and everything broken in, I plan on building up the spare block I have for boost. Bored .020 over, RTE pistons, eagle rods, ARP studs, megasquirt, a simple t3/t4 on 8-10lbs of boost, and I don't think I'll do anything else more to the car besides maybe a bigger front sway bar (going to take off the rear sway bar first and see how it reacts) and grippier tires (205/50-15 Advan AD08Rs are on my list, really good tire.)

I'll say this, I removed my rear bar (ford 8.8) and while the car feels neutral for cornering, it's very difficult to hold a drift. It's like an on/off switch now. And when it hooks up mid drift, I get wicked snap back oversteer. I think more power could help this.

I am getting really excited, lots of suspension tuning to do to test out more fun stuff when my LSD gets put in, setting it at 65% lock on accel/30% decel (set at 100%/45ish% from factory, really only good for drifting.) I'll post on here how to set theoretical lock settings on clutch plate LSDs when I take it apart.

Ended up dropping off my spare diff carrier, new bearings, and the LSD at the diff shop yesterday. If you are in the Bay Area, Ty at Bay Area Differential and Gear Garage in Hayward is your man. Awesome guy who really cares about his customers, he has no problem spending time to help you understand what he does, even showing you how himself. He even went out of his way to get my differential back as soon as he can because my car is my only means of transportation, which he said would be Saturday at the latest. People like him are really rare in the automotive repair industry these days if you ask me.

Here are some pictures of me re-arranging the clutch packs on the LSD for less lock before I took it to the shop.

There are 4 countersunk allen head screws that need to be removed in order to disassemble Kaaz/Tomei differentials


Cover off, you can see one side of the clutch packs.


Here we see the order of how the clutch packs are arranged, 6 disks for a total of 6 friction surfaces, meaning this came 100% locked, not what I want. Arrangement order, ABABAB where AB and BA denote a friction surface.


We rearrange the disks to create less friction surfaces lowering the total lock. since there are 6 disks, we can rearrange from 6 to 4 or 2 friction surfaces. 100% lock from 6 surfaces gets us 16.7% lock per friction surface. By swapping the last 2 discs from the right, I disabled 1 clutch disk thus I now have 4 friction surfaces as seen below, so ABABBA, 4 surfaces x 16.7% = 66.8% total lock to the wheel with the least traction. This is inline with what the manual says, 4 friction surfaces is around 65% lock which is what I want. 2 would be 30-33% total lock. Along with the 1.5 cam angle, 55 degrees on accel, 20 degrees on decel, I calculated I would be at around 24% lock on decel. 


A look at the center section and stacked plates with preload ring.



And that's it, slap it back together and you are done, 100% lock is not ideal for grip driving, and with the low initial torque that this LSD has at about 40ish ft/lbs, it would pretty much act like a welded on acceleration and cause the car to be really understeery when grip driving, sure you could tune it out, but I am not solely drifting and my car does not make gobs of power so I have no reason for 100% lock on accel. My car is built as an all rounder that does everything well. Keep in mind those percentages are theoretical and vary depending on your suspension setup, how grippy your tires are, the amount of power your car makes, among other things. Keep note this clutch arrangement has to be done symmetrically on both sides. 

Next post will be the removal and install of the differential carriers.

How interesting, the clutch discs have the hoz/vert grooves to create the different friction surfaces. Never thought that was how clutch pack LSDs work! I thought it was clutch discs + spring (Eaton posi?)

Plus, this way, you won't wear out your diff prematurely. Too many guys think the roadway is a track... sayonara clutch pack. A track or drift car needs the 100% lock. Good job man. The world needs more "all arounders"

Also a good point haha. I was on the roof about maybe leaving it as is at 100% just to see, but I feel like it would really mess with daily drivability.

Yay, updates! Well not too new as I have just been too lazy to post because of work.

Lets continue, here is the pile of shit I bought to basically net me a brand spankin new rear end, albeit the differential included, ended up being a grand total of $1315 after labor and such. Every new OEM seal for the rear end, koyo bearings all around, and new center support among other things. Most of ya are probably like why the hell did you spend that much on a T series rear end. Well, because I can lol. It's lighter than any other option, I don't mind drums (constructing rear disk setup eventually), and it will take the abuse I will put through it.


Yay, tight, fresh, and will take a beating, just how I like it :spiteful: The pattern came out great, new bearings, and a solid pinion spacer from Weir. Don't mind the color, dude ran out of black paint and I told him to spray it with whatever he had haha.


Popped the axles out and dropped them off to my buds shop to get the new bearings and races pressed on.


Dropped out my old 320k mile differential and cleaned the housing and gasket surfaces.


And here's the source of my horrid noise. LOL. It's not that bad.




Whoops.


And after some picture magic, everything is back together! Axles do not need to be trimmed on aftermarket LSDs.


Put the LSD sticker on the housing that came with the diff, makes the car have 5 more horsepowerzz


Then me and my buddy took the car out to the industrial and did figure 8's, clutching in while cornering for about 40 minutes, it was noisy at first, but was quiet as shit by the time we were done. Drove home, dumped the fluid, everything looked nice, filled it back up and have been driving it since with no issues. Let me say, HANDS DOWN, the LSD is the best mod I have EVER done to this car, the amount of grip I have cornering now is ridiculous, I can't get enough of it. The car is super predictable now, and will only slide if I make it slide or dive into a corner fast enough, and it is FUUUUUUN.  If you are thinking of putting in a good LSD, just do it, you will not regret it what so ever. I seriously fell in love with my car all over again. PS: IF you ever think of getting the Xcessive Engineering tranny mount, DON'T, the vibration is hooooorrid on a 22RE, unless you want your teeth to fall out before you become senile. Swapped in a new stock rubber mount and smooth sailing from there.

Well for an end note, I ended up getting the Cube Speed short shifter from AUS, pretty neat, and good craftsmanship, installed it yesterday, drove with it today. Verdict: good buy, crisp shifts, really really short throw, like 2 inches of throw between 1-2 and so forth. That and it looks bad ass. Only grip about it is that it sits a little further forward that the stock shifter, but it's not so bad once you get used to it, just have to stretch your arm further than you normally would and my bucket seat doesn't help it's case at all either lol.


That's all for now folks, no idea what is planned next, maybe new tires and turbo :heh:

I really really need to do something with my diff too. I honestly thought about getting it re-sealed and rebuilt, but at this point I may as well spend the money on an 8.8 like swan song. I really want a good lsd option though. Decisions decisions.

That's why I've been leaning a little more towards the Ford setup. My problem Is that there's really nowhere in town where I live that'll shorten it, much less do it properly without messing something up.

Yea the cube shifter is great. of the bestmods ive done and yea when i shift into 3rd it sometimes hits the ash tray bt i plan on heating it and bending it slightly beyond that its great. It is noisy and the first couple of days its hard to row though the gears bt now after 2months it gotten smoother and shifts awesome!
