Tranny, and LSD

[OrangeAppeal]

Don't forget that the Axles on the MSP are also different from the MP3 and Protege ES. You will need them as well to complete the swap of transmissions.

I think you could use the axles from the MP3 or the ES, just the shafts on the MSP are thicker....i'm pretty sure the end spline count/diameter will be the same.

well, since I haven't experienced the infamous 'clunk' yet (haven't got any MSP / MP3)... I am going to ask a dumb question.

can we just take off the racing beat sway bar and throw everything away and buy an aftermarket sway bar instead?? would this solves the problem?? I am assuming the aftermarket would have bushing available with the sway bar?? would autoexe have one??

I don't see why you couldn't get one from elsewhere...
It's just a sway bar.

However, I believe everyone's issue is that the factory ones should NOT cause any problems!!!

Why should WE have to spend money to replace parts that MAZDA didn't do right?

Yes, the transmission has to be opened up to install a limited slip.
Most quaiffe ones are not viscous, they are "clutch" based.
viscous is more driver friendly, and makes the on/off effect of the limited slip "transparent". its a smoother action when it starts to work etc.
The quaiffe one is built to withstand racing stresses, and will certainly be a good product.
I know lots of guys with quaiffe lsd's in other cars, and have never heard a complaint. of course, they are rally cars.
the clutch action in the quaiffe comes on fast, and really works hard.
both do the job, just in different ways.

I read a really good article somewhere on the net spelling out the differences between the various kinds, but can't find it now...

The quaife's are not clutch based. They are a mechanical design that uses gears, not clutches. Have a peak inside one here: Quaife Info

Also, LSD's will not get rid of torque steer. They may reduce it, but they won't get rid of it. If you want to get rid of torque steer, weld your diff. I have a quaife in my mirage, and it still torque steers enough that you have to grip the hell out of the steering wheel to hold it in place.

Clutch-type LSD's work well, but some of them require special maintenance (ie. oil changes). Viscous LSDs use a thick fluid.. I think the biggest problem with them is that they are a little slow to react. My old AWD talon had a Viscous center lsd and you could see my front wheels spinning for about a second before the back wheels got power.

FYI, a HUGE advantage of the quaife is that it has a lifetime warranty. If you break it, you get a new one, and they are good about replacing them. Even if you race with it.

A disadvantage of the quaife is that if one tire is on a zero friction surface (hanging in the air) then the other tire is not going to get any power. Hopefully you won't be lifting your front tires into the air though.

God damn right!

sorry about the swears

I've heard that if you are in a situation where one tire is in the air and just spinning, applying the brakes a bit will exert the necessary force to make the LSD kick in and pull you out. I've only read about this with awd cars though.

 

[Logan]

That's a trick you will also find in the manual for a Hummer.

 

[MikeyG_U2]

Ah yes, that is where I read that. It makes sense to me, perhaps it would work on a less advanced differential as well.

not to sound like a moron or anything, but i was under the assumption that one wheeling it was a bad thing with a quaife dif. In their instructions i believe it says something about when jacking the car up (in the front) be sre that both wheels come up or else you risk breaking it. I would assume that this would hold true for getting one wheel up in the air while racing. I've never personnaly had my front wheel (have had the rear up though) in the air. Just something that i was thinking about while reading this thread.....
