Big Bore's like 92mm (1835cc) or 94mm (1914cc) tend to be bad news on type3's. Stay away from anything bigger than 88mm (90.5mm MAX!) if you want your hot new motor to survive more than a few Christmas' of regular driving. The larger pistons produce more friction related heat due to added surface area in contact with the barrels. This is the kind of heat NOT accounted for by the stock cooling mechanisms (i.e. engine tin) of the VW type3. I know it's more expensive in the short run to stroke a motor (crank size above 69mm), but the longevity of your motor will pay for it in the long run. Do not stroke a motor above 78mm, as a throw longer than this results in balance and heat problems (not to mention barrel risers way too thick to be advisable). My motor is a 88mm (piston)x 78mm(crank) equaling a displacement of 1897cc. With the Berg special's as carbs, this motor friggin' cooks. I do believe that this type of performance will make you one HAPPY individual. Good luck.
