I might add that the S2000 is routinely raced. And it has been a top winner
in SCCA Autocross for years. So, there should be lots of resources out there
for performance mods and racing upgrades.

dimensions).

just how wild they can get with exotic motors for me to build. I already
built two motors and this last one, even with parts help (and my age), was
expensive as all get out. Now I am hoping for somebody else to pitch in...
If all the parts had to have been purchased new for this 260 motor, it would
be really expensive, lol. Thanks to lots of folk, I got real parts help on
this one...
