R33 Diffs

[r33_racer]

Ok, so I got a 2 way diff from an importer out of an r33, dont know what series it was. However we took out the std lsd from race car last night and compared the two diffs. The one we took out of the race car (series 2 97 model) is a little bit longer overall and it has some sort of sensor just behind the yoke. The other diff which looks identical except the shorter length and lack of sensor clearly wont go in now without some modifying.

What im curious to know is how many different r33 diffs are there? and are they interchangeable somehow without having to do the obvious and machine up a spacer plate for the tailshaft to reach the yoke?

Has anyone encountered this before?

We have a tomei 1.5 way centre were putting into the std diff so were sure to have a mechanical diff that will work regardless.

Thanks.

I think the sensor may be somesort of speedo sensor, whether its a secondary sensor to work in relation with the gearbox drive or what im not sure. Does anyone have any idea on this maybe?

Cheers.

I was only aware of R33s coming with either the standard viscous LSD or an active LSD (you will have an ALSD dash light in the middle of your tacho if this is the case).

If it's anything else I'd assume it has been changed for something aftermarket.

Yeh the other one we got from the importer was a std viscous LSD with a changed centre...a locked 2-way. But the whole housing is different. Thats whats changed. I would have figured they would have been the same. Ahh well we got the std one fitted with the tomei centre...all good now.

The difference would be abs vs non-abs
