The Kattchee Bros. have two of the nicest Giulia Sedan's around. One is a "sleeper" Super with 2.o twin spark and the other is a B Sedan Ti race car.
They also make cool parts:
-aluminum pressure plate like in the 911S which are no longer available
-drive shaft donut scatter shields.
and probably more. for more info email chris kattchee he is very friendly and can help you with the items listed above or if you want to know more on what they did to their twin spark super
