Default 05 STI front LSD into a 05 WRX

Is it possible to dissemble a 05 sti front lsd so its just the diff and swap it over to a 05 wrx with a 5MT using the gearing off of the front diff in the wrx?

I'm not sure if this would work being the sti is a 6MT that uses different axles than the wrx, but it'd be interesting to know if its possible.

Thanks

Dang, kinda figured though. It's because of the different bigger axles right?

Could you swap in sti axles and hubs and then still fit an sti axle into a 5MT with the swapped diff or would the axle be too big around to fit into the holes of the 5MT even with a swapped sti diff? Or would nothing end up fitting because the sti diff itself is too big to fit in a 5MT case?

That's the rear diff, not the front. The ring gear on the front diffs is the same size, but I still don't think it will fit.

you are right, it is the height of the diff thats the biggest difference, by looking at the differential sticky thread the 6 speed differential looks 3 to 4 inches taller than the 5 speed diff.

Gotcha, thanks for the replies guys! I'd be sweet if I could find a torsen or suretac front diff for a decent price, but I'll probably get a 6MT if I was to put over $1K into just the front diff.
