As I am struggeling to ensure sufficient grip for my 205 S16 turbo, my devious plan is to convert it to 4x4 using PSA components only. So in short the details are:   reinforced 4x4 drivedrain: strnger rivets and splines in the center gearbox and stronger flanges for the centershaft.   I will modify a BE3/6 gearbox and add the centerdiff to this housing - enabling 6 speed and higher rear ratio.   should be fun :-)   anyway please find a couple of Pictures to get it all started :-)
