I have a B18R engine waiting to be dropped in my car but I have difficulty deciding what to do with the transmission , these are the options:

use Y2 gearbox rebuilt with ITR LSD , cable operated
use S80 gearbox , hydro operated

(to stop confusement Y21 = hydro)

I can trade S80+standard Y2 against Y2 gearbox rebuilt with ITR LSD but the S80 is a rare piece and it has only got 12Kmls

problems:

S80 will not fit that easily , there are NO engine mounts available for this setup for a 90-91 CRX/Civic SiR/1.6iVT. making one myself is not an option.
The only solution is a custom mount. A friend of mine is working on this and Brian (Hasport) confirmed he is workin on one as well. BUT I do not want to wait several months, I want the swap done next month (at max)

So I heared about the possibility of swapping S80 internals into a 1993USDM Integra GSR gearbox (cable operated) . Is this possible? Where can I find this casing or a busted tranny?

A solution for the time beeing would be using my old Y2 (w/o LSD)
