Hello, Bjorn and thanks for the research on engine conversions. The 5
cylinder conversion does have the positive aspects that you mentioned
and you should rethink your appraisal of the Syncro appplication. The
conversions being done by Detlev Hanschke  DO NOT  reduce the ground
clearance as he is using his own superior design for the exhaust system.
The Winkler exhaust system is a clumsy design along the lines of the SA
system which is unsuitable for Westys and Syncros. Detlev has come up
with a system that works in these applications without reducing ground
clearance. The engine skid plate is retained at its previous height and
the engine lid also (with a small bulge). The broad smooth power band of
the 5 cylinder is a huge advance in power plants for the Syncro IMHO.
