Looks good but .54 BSFC is no great shakes :)

It needs a longer intake pipe.

     In the small, 90 cc Yanmar Diesel air and charge cooled engines, a
long intake pipe
gave advantages up to a lenght of 14 inches, the longer the pipe, the
best low rpm
power output, but a shorter pipe improves high rpm performance, and also
starts, specially
in cold weather, if I remember well from charts appearing in this site,
in Mazda size
engines, no favorable data exist for intake pipes above 20 inch.
Please tell us about your results!
    Nice weekend, best regards. Salut

This data is from the Lemans winning engine.
