Pretty sure the Torsen LSD is 1.5. I'll double check though, I've been wrong before... happens about once a year and I'm due .


Bah, you're right. 1 way.

 

I had email the Quaife Co. about the LSD and what they had to offer, they told me that they did not make an LSD for our car and said that the one we had from Honda was a very good one. I will post the emails for all to read

 

As promised

Hi,
Do you guys make an LSD for the Honda S2000?
I own a 2002 Honda S2000 (AP1 F20C) and I am looking to add a 1.5 Lsd to the differential.
Thank you

Ben,
Thank you for your inquiry. We have looked at replacing the factory LSD in the past. The way that the stock unit works is very similar to ours, so there would not be a big difference as far as performance. The part of the third member that is breaking is usually connected to the bearing caps. This is a flaw in the overall design of the rear end. You may want to contact Comp-Tech for more information on the bearing caps as they have developed a strengthening device.

Thank you for your reply,
I am aware of the Comp-Tech rear. I was just looking to upgrade the LSD.
Thanks
Ben


Have you broken yours? The way the Honda unit and ours work is identical. For a 1.5 way unit, you would need to look at a plate or clutch type unit. They are very different from a automatic torque biasing unit such as ours.

Hi Jason,
Thank you for the time and info you have given to me.
"Have you broken yours"? No I have not.
I am just learning about this rear.
Some of the guys in the club I belong to have added this change to the rear. They must be talking about the cluch type LSD you are refering to. Is there a big difference between the two types of
LSD's and is there an advantage to one over the other? I am not looking to spend money just to say, "I have an LSD".
My S2000 is, for the most part, a road coarse car.
Once agin Thank you for your time
Ben



Ben,
The truth of the matter is that the S2000 comes with a helical type differential already in it. The clutch type, or plate differentials, operate in a very different ways. The clutch type uses a series of clutch plates that lock the side gears in place when you accelerate or decelerate. The 1, 1.5, 2.0 way refers to when the differential is active. The Quaife unit is a helical gear driven type that is constantly variable. It is working at all times, unless you break an axle or pick a wheel up entirely off the ground. The unit does not work in this instance because the differential is a torque multiplier, and if there is no resistance there is no multiplication. There are pluses and minuses to both. it just depends on what you want to do with it.

What's a different between 1, 1.5, and 2way, if ya don't mind me asking.

 

1 way - LSD "Locks" under Accel. only
2 way - LSD "Locks" unedr both accel. and Decel. ("Locking" effect when you lift off the gas" - Drifters use the 2 Way LSD.
