mk3 LSD diffs in a S54 box

[Paul Woods]

You are correct, any upgraded LSD for the mk3 will install into a mk2 NA.

TRD & KAAZ both have the SW20-NA and ZZW30 listed with the same LSD part numbers. The interesting part is they have AW11-SC has the same LSD part number as the SW20-T.

Yes, i believe there is some similarity between the SC gearbox and a rev1 Mk2 tubby box.

Bump up this old thread :P

So if i'm right this diff will fit my 3S-GE Gearbox?

[Paul Woods]

Yep that will fit

Paul is there a reliable way of testing for LSD in a gearbox that is not in a car
Or do we need to pull open the diff casing?
Reason I ask is a rev3 box has come up for sale close to me and the guy is sure it came from Japan already with LSD fitted, now we know its not an option on N/A's but it would not be unusual for someone to have fitted it

[Paul Woods]

There is no foolproof way unless you open the box up, most of these LSD's are torsen ones, so they will indicate a non-lsd diff type with any test.

Do I need to start a another thread to ask which FD would best suit a 2GR (presumably hooked through an E153?) in a Mk1a? I'm thinking 3.9 would be the best compromise for a road car, although the 4.2 FD would still be usable :)

The 3.933 from the ST165 will take you 9% increase in gearing IIRC. It's a good mod to allow the engine to sing!
