ok im looking at a conversion to a 1.8l jetta = engine. What other transaxles of VW or AUDI would fit up in the allowed = space. Also if it was a front wheel drive. could i have the gears = revearsed. IE porsche 914 transaxle 5 speed would it fit? But also bolt up = to the engine. I want to switch to an automatic or a 5 speed for sure = just need recomendations
