If you are using the 1.6 transmission you don't need to change any parts in the driveline besides the clutch and flywheel. If you use the 2.0 Beta transmission you will need to use one of those axles or both Im'm not sure. I'm using the 1.5L transmission on my beta swap so I don't have to deal with that headache. I know it's only gonna be a suitable replacement for the tib or elantra axle as long as I stay N/A but if I o boost It'll need the beta tranny and axles for sure.does anyone know if im gonna have to swap out the driveshafts when i do the beta swap? if thats true will they fit without having to replace any other conponents?
