The company in Australia that converts "Wasserboxer" motors into "Oxyboxer" motors is Hellbug Engineering in Sydney. Their website at http://www.hellbug.com.au/engineering.htm is quite short on detail. But, what they do is machine off the cylinder barrel water jacket on each crankcase half and then rebuild the motor as an air-cooled motor. Apart from the strength and reliability of the crankshaft, the strength of the case itself, the full-flow oil filter system and greater oil capacity of the waterboxer crankcase are what the attractions of these cases are. A major problem they overcome is lining up the waterboxer crankcase stud holes with those on air-cooled cylinder heads. They do this by manufacturing and installing specially made cranked studs. Some people have been very sceptical about this, particularly over how long these cranked studs would last. However, the issue here I understand is the possibility of using a Wasserboxer crankshaft in a Type 3 motor because of their strength and reliabilty. But, has anyone considered using the crankshaft from an air-cooled 1600 series CT motor. This engine is a flat Type 3 style motor with single carburettor and was used on T3 Transporters (Vanagons) from Aug 1979 to Dec 1982. (It is not a Type 4 motor like the early 2 litre air-cooled Vanogons.) Although, possessing only the same power output as a stock Type 3 motor and having to push a large vehicle like a Vanagon around, they had to work very hard. So, VW built these CT engines bullet strong. Just a lateral thought!!!!
