Curtis & other Europaphiles,
Oops, hit the wrong button on that previous transmission.
The main difference between the 912 and 914 are different compression
ratios due to the different pistons and (I believe) connecting rods.
The three engines 912, 912S and 914 all have different compression
ratios.
Of course, the exhaust systems are quite different due to the
presence of the turbo.
There are also differences in the lube system to support the special
lubrication needs of the turbo.
There may be other differences.
Good building and great flying,
Bob Borger
