Actually, the compression ratio in the KX/JT engines is 8.5:1.  This
is quite a bit higher than the 7.8:1 compression of the single knock
sensor MC engine, and much higher than the 7.0:1 of the urq engine
without knock sensor.

You really do have to be careful if you try to graft a turbo onto the
KX/JT engine.  Yes, it can be done, but there are a lot of hassles,
limitations, and care that needs to be taken with it.  Most people opt
for a real turbo I5 engine because, although it takes a bit more work,
you have a much more robust system with much greater potential for HP.

Now, I really like the idea of that electric supercharger that is on
the market.  Unfortunately, at $1800 a pop, it costs about as much as
a turbo I5 swap.  :-(

Later,
Eric
