the 7MGE is the same as a 7MGTE with the exception of the turbo and related parts.
as far as the ecu's, they usually are the same, as some Toyotas used an external 'ecu' for the trans. i suppose if y'all are any good at wiring, you could just add to the harness as-is as far as the additional wiring is concerned. you'll probably have issues with things like the clutch safety switch and cruise control. i'm not sure if the fuel pumps are the same. get a Toyota factory manual.
