i don't know about the auto tranny, but the R150F 5 speed from the '89 will bolt up to your turbo motor, but you need the turbo bellhousing. you'll also need an adaptor plate to run gear drive cases and you need to convert them to 23 spline.
the straightforward way to go is to get a R151F turbo 5 speed, but they're expensive and hard to find
