Saab 2,3ltr T to Opel 5 transmissions

Hello, a question to the Saabfraktion: That the Saab 2,3l and the Opel Ecotec 2,2l have the same GM block should be known. Is anyone known if the Opel 5 gears like it e.g. the B Omega in the 2,2l version fits easily to a Saab 2,3l turbo engine? The Opel drivers in the foum don’t know anything more exactly. According to my info. Don’t let me teach you a better one!
