Most, if not all of the turbo oil and cooling is bolt on stuff. The 
water is supplied by a fitting on the water outlet neck and returns via 
a special freeze plug. The oil comes from a sandwich adapter that fits 
between the oil filter and block. The only one I'm not sure about is 
the oil return.
