A Boston Engine 1.9L WBX is now in my '84 Vanagon and running.  There is still much work to be done before it moves.  Only problem noted was a leak somewhere around the lower thermostat housing.

Biggest problem getting the new engine in and ready to try out was the S&S exhaust system.  Other time consuming problems were various new parts that didn't fit.  I wound up using several old hoses, etc., as the new ones didn't fit.
