Blown Cressida Diff

[assassin10000]

The 1 way seems ideal. I don't fancy having the diff lock up on me on a wet night when I back off from speed. Unless I've misunderstood the effects of a two way.

I would recommend 1.5 way.

1-way on decel unlocks and can cause the car to spin easier/faster.

1.5 maintains some lock on decel, but not enough (usually) to cause problems with spinning by suddenly going off throttle (this is why it's recommend for beginners/intermediate drivers).

2-way rocks. No problems if you get used to it. There is NOTHING to be afraid of in the rain, you just need to be aware of your car, it's limit and what your right foot is doing

People that are scared of 2 ways just don't have enough knowledge/car control to utilize one correctly. I currently run a spool which doesn't feel ANY different than my cusco 2-way sideways at all, just a little more consistent in initiation. The BS about problems in the rain is just that, bs. the same people that are having problems in the rain would have the same problems with an open diff, they just pushed themselves beyond their (and their cars) limit.

I'd recommend the cusco RS unit, as it has a very smooth engagment and is less likely to cause you any problems. Plus with the right fluid (Motul 90pa being my favorite out of redline,amsoil,mobil1,valvoline,buncha dino oils) it locks amazingly well, and quietly too.

Any ideas what he might have been looking at and why it looks so different to what I have?

At a guess, your old LSD centre was a 2-pinion diff and the new one is a 4-pinion diff.

Thanks Andrew. I'd love to go as tough as I can without comprising the overall feel of the vehicle which is currently a good balance between total take-it-to-the-shops-idle-in-traffic-on-a-hot-day driveability and fun-style power. I'm always looking for the weak spots and I appreciate the advice.

Here are the pics and info from the website. Now, I'm liking the idea of a 2 way more and more...

NOTE!
Two basic types of limited slip differentials are available depending on how the initial torque is created.

--------------------------------------------------------------------------------


1. Type-RS
　Low initial torque type using RS springs.
2. Type-MZ
　Initial torque created by the cone plates.

NOTE!
Type RS for low initial torque.
With the Type RS, the initial torque is absorbed by the RS springs therefore the initial torque comes on gently compared to the...
Type MZ which comes on stronger as it uses cone plates and response of the LSD is better, as the friction is lower.

*Lower initial torque *Lower power loss *Reacts well to delicate pedal work *Durable and develops initial torque steadily




NOTE!
Three ways to set your CUSCO limited slip differentials :

1. one way,
   
2. 1.5 way and
   
3. two way.

--------------------------------------------------------------------------------
･ One way L.S.D. specially suited for front wheel drive cars and 4WD car front axles.
Activates under acceleration, and acts as a true LSD when the throttle is off.
A great chance for improved lap times.
A CUSCO original design.
･ 1.5 way LSD
Activates under acceleration while the under-steer is less than on the 2 way LSD.Recommended for drivers having difficulty with 2 way LSD under-steer and one way LSD braking.
･ Two way LSD
Recommended on the rear axle for rear drive cars. Activates on both acceleration and deceleration. Recommended for those who
prefer hot driving action and big angle drift.

NOTE!
One Limited Slip Differential, Two Ways to Enjoy.
With CUSCO's LSD, you may change the setting during your overhaul with no additional parts required.

Do you have any more information on that? Who got the 4 pinions and who got the 2 pinions? At a guess I'd say the 4 pinions are stronger/better/more desirable?

[Norbie]

Yes 4-pinion diffs are more rigid and thus stronger. I know the Hilux got the 4-pinion and I'm pretty sure the MA70 did too, not sure about MX83.

Get yourself a nice TRD clutch pack LSD. These are the duck's guts.

yep
easily on par with a cusco
more $$ though

[V8Cressida]

Which would be easier to get? Any other pros and cons for each type?

[MR 1JZ]

the TRD would be as easy to obtain via nengun...

[The Real Roadrunner]

the MZ is the track diff, very harsh and noisy and awesoem for a track car...but a bit too rough for the street...

dont get a KAAZ either...very mean diffs for the street...

only someone as soft as you would say that

[MR 1JZ]

bro i eat glass and wipe my ass with sandpaper

I live in lockertown

hahahaha

yes I know your just stirrin

[1JZ.747]

my cig locker factory g series is the best diff i have ever had

[FASTFOO]

WOW I remember that diff
It is MA70 4 pinon clutch type LSD in an MX83 housing.
And should still be good with shims and clutch's replaced.
Interesting though some months after mr smith had got it from me I payed out a warranty claim on it as he said he had only just got the car going and the diff was no good

Anyway you can shim the shit out of them and make it as tight as you like. Its just that they wear a bit quicker than some aftermarket one's.

P.S. Just kiding about the dog dont call the RSPCA

Sounds interesting, how do I go about doing that?

The reason I removed your diff was because I left a long black sinlge left wheeled line so I thought it needed a rebuild or something. Mechanic said it looked very different to the 4.11:1 that's in it now. I wish I had pics but I don't. Thanks for your input though. Priceless piece of history.

[HKS_TRD]

I went for a drive last night with the new 4.11's and I'm loving' the extra pep. So much fun to drive around. It's always ready to accelerate hard. Haven't "tested" the LSD yet. What's interesting is that my mechanic tells me that the internals in the 4.11:1 look "completely" different to the 3.89:1 "LSD" that came out. Unfortunately I didn't get a picture of it because he buttoned it up before I could get there. He says he could definitely see what looked like shim or clutch type packs. Any ideas what he might have been looking at and why it looks so different to what I have? Does anyone know Leon who I purchased this from and what he might have done to it? He said it was rebuilt a few months before I got it.

The 1 way seems ideal. I don't fancy having the diff lock up on me on a wet night when I back off from speed. Unless I've misunderstood the effects of a two way.

You need to buy my TRD2-way for MA-70, I am assuming it fits in the Cressida housing? Want to sell your 4.11 gears?
