Swapping F20 to 4T40E

Post by miker33 »

Hi All,

I'm looking at converting my twin engine car from using 2x F20 manual boxes to 2x 4T40E boxes from the Daewoo Lanos (assuming I can get them into the engine bays as they quite tight)

Does anyone know if the F20 drivehaft CV splines are the same to be able to fit my current F20 shafts\CV's directy into the 4T40 or will I need to use the 4T40 inner CV's in which case are the shafts used on the F20 CV's the same fitment into the 4T40 CV's? Also are the drive shaft lengths the same for F20 fitment (when using the small dummy shaft setup on the F20)?

Many Thanks,
Mike

what chassis is this in? I think the left side shaft will do but the right may likely be different, shorter on the 4T40E that is.
