2way Or 1.5way Mechanical Lsd? Feedback Wanted.

[Sydneykid]

With all styles (1, 1.5 and 2 way) you can adjust the preload (before fitting) so they "open" at lower loads. Hence they don't skip when doing U turns etc. The skipping has nothing to do with the diff being 1 way, 1.5 way or 2 way. Unless you are doing the U turn in reverse of course.

Some Nismo diffs enable you to adjust the preload after they have been fitted. This is done through the axle holes.

So can you get a 2way rebuilt as a 1.5 way?

That wasn't the point of my previous post. So yes, you can change the plates, but it's not cheap as it requires replacing almost every working component. Much better value to sell the 2 way and buy a 1.5 way.

I have a Cusco 1 way. I've found that when under hard acceleration then suddenly step off the throttle, the nose of the car darts to the left somewhat (not swapping lanes, just neccessitating a slight steering correction). Is this common for 1 way LSDs going from accel to deccel?

I bought the car with the Cusco in it already so not sure if it's still healthy or not...

I know the ramp angles can be changed to alter the nature of the diffs but if the manufacturers dont know how to set them so the diffs arent grabby how would you or me do it? Trial and error, try it, remove diff, strip, adjust, rebuild, refit, try it etc?

Cusco diffs are sold as capable of running 1.5 or 2 way but I dont know how you change from one to the other. I wasnt aware of any additional parts being needed. I know parts are needed with Kaaz diffs so maybe the impression I got of the Cusco was wrong.

Im not a diff expert though, Im just passing on my experiences

Rezz,

Sounds more like a suspension/bush problem to me.

a friend has commented, using his rx7 which came with a 1-way mech from japan, that it would struggle to do donuts, where you are on/off gas alot, as soon as you are off gas, it unlock straight away and the car starts to understeer / straighten up. He didn't mention anything about the car jumping to the side or anything. Perhaps this is caused by the engine braking, locking up one wheel

There was a thread a while ago, on changing an lsd from 2-way to 1.5way, i think it was a cusco diff, and i got the impression that you can do this to some diffs with relative ease. Maybe do a search on this see if you can dig up any more info.

The link to the cusco site kinda explained how to change from 1 to 1.5 to 2 ways

You just have to move the pin to a dfferent hole in the plates and change it's orientation.
