Time for an Evo RE-BUILD thread.

Helical I believe.

Cool. I didn't know what the normal style was for front bias awd thingies.

[TouringBubble]

Let me know how the rear rebuild goes. I'm looking to do the same soon. Not sure if I want to realign the stock plates or get the additional plates.

As far as the center diff its going to get a new unit from an 2005 Evo Rs, its a good upgrade and option before upping to high dollar 1.5 way after market LSD ( and much better than what I had). and the rear is going to get a 12 plates set up instead of the stock " missed aligned" 8 plates. C

What kind of LSD?

The good kind.

[TouringBubble]

What kind of LSD?

Probably similar to the IX LSD up front. Helical I believe.

My car doesn't skip or jump in tight turns...unless you're slow enough to consider backing out of a parking spot a tight turn

Yeah that. That's the only example I got lol

The differential limiting force is increased when braking; entering a turn which gives greater stability and also when exiting a turn which gives better steering responsiveness, stability. The diff slowly opens when approaching the apex and slowly closes when exiting. So yes it is open in sharp turns when the greatest steering input is used, but it is partially "closed" when decelerating beginning the turn and accelerating when the wheel is unwound. It has to be open to let the back wheels turn at a slower rate than the front or it would skip/jump on really tight turns similar to a certain white 240 I know; except ours is the center diff opposed to the rear diff. Same concept. But that's the only time you want it open.

"If you're doing it right" you should use the least drastic steering inputs possible = decreased open position in the ACD.

I've tried researching the center diff and how it works. From what I can tell, the active center diff goes open when the wheels are turned. We do a lot of turning in AX and RX.

[nicktcr]

That thing will be scary with a limited slip. I couldn't believe it was open diff when you told me. Nothing like a good breaking of parts to justify some sweet upgrades

[c-evoVIII]

Hers' the list of things that's going to be done to the Transfer case.

Stage 1 Transfer Case
A complete rebuild using OEM Ring & Pinion gears and new OEM
pinion bearings. This rebuild is perfect for the daily driven street car
and can handle a good amount of power.
Also included:
8mm to 10mm bolt upgrade
New seals and o-rings
Reshimming
Neodymium magnet

1 Limited Slip Differential
1 Differential drum
1 Machining/repair of internal component(s) -viscous repair

Both the Transmission and transfer case are going to be solid and " It will handle 500-600 hp/tq with no problem!!!" Trevor @ Sheptrans ( my car wont see anywhere close to that number but the head room sure is nice to have). Then after they are done the rear diff will follow for some work as well. I cant wait to feel the car with actual limited slip for more grip ( anything is better than the stock open diff) and a lil more go. C
