Quaife LSD on a D16A6...worth it?

I'd go for it. If you can get onto crx.honda-perf.org, PM a guy name 'o tommy (yeah, he's not very imaginative with his names ) He's got the quaife mated up to his ZC, which is as close as anyone I can point you in the direction of.

Stick,
If you can get a deal on a quaife,I say Go fer it!
I intend on running quaife as soon as I ante-up like $900! Yikes!

I know, they're insanely expensive brand new. I would never buy a brand new one for a D16A6...I'd upgrade to a B16 before buying a quaife new.

Another question...from what I've heard, LSD helps give you better fuel economy because you aren't "peg legged" anymore. It sounds like a reasonable argument, but is it true?

err...I dont know firsthand.I cant see how a LSD will improve gas milage though.
I do however know that the quaife allows all around better traction into And out of any corner.That in itself is a big selling feature for me.

It's possible, I wouldn't doubt that because you now get power to where it's most needed you don't have to overexert the car and can probably save some gas, but I wouldn't say it would get you that much of a noticable increase.

Ok. That sounds reasonable. So if there is a gas mileage benefit, it's probably marginal. If i do go ahead and get the Quaife, I may take some gas mileage readings to see if I can notice any difference. (before and after).

Damnit...it looks like this Quaife is the wrong bearing size for my transmission.

EDIT: Quaife's information on their website is wrong. Most 88-91 Si's have 40mm bearings. All DX'x and HF's have 35mm bearings.

There IS a way to make it work... dang I am completely going blank, but I'm almost positive that there was a way to make the 90-91 quaifes work in 89 trannies.

I don't think, and have not heard otherwise, that there is a safe way to fix this issue.

The only Differential bearing sizes offered are:
O.D.: 80mm I.D.: 40mm
O.D.: 72mm I.D.: 35mm
Researched this for 3 months. Looked at non-automotive bearings too.

You either have to use a transmission case that accepts the needed size bearing or get a different differential. I suppose someone could play with fire and make a 'fitting' that allows you to make a 'small bearing' differential fit into a 'large bearing' case but that wouldn't work the other way.

I'd be very interested in any other method to fix the issue at hand.

I just bought a sleeve adapter from KAAZ for $65 that fits over the differential shafts to allow you to use the 40mm bearings on a 35mm differential. As soon as they arrive, I'll let you know how it works out.

Me likee as well.
Let us know stick..
