JDM legacy 4eat diff ratios and other tranny Q's

[bugeyes]

I'm in the middle of an ej20g (from a jdm bf5 legacy) swap and contemplating what transmission to use... I could use the stock tranny (usdm 97 obs 4eat), the jdm 4eat that came with my clip (no rear diff), or a manual tranny off an rs.
To use the jdm tranny, I need to know what the diff ratios are, especially the rear diff since thats the one i need to replace.
Also, will the ecu off the clip work with a manual tranny being that it came stock with a 4eat?

thanks

Yes it will, it should be much like the usdm bf ecu, there is one identifier wire that will need to be cut.

thanks... thats not my first choice, but if i have to ill do it.
does any one know the jdm 4eat diff ratios?

I am 99.9% sure that the rear diff is 4.111
