A bit of info on turbos (courtsey Ned Ritchie of Intended Acceleration,
if anybody knows he does) posted to the 20v list a few weeks ago:

Notice the 300 max continuous for the stock K26, so the idea of that
turbo maxing out at 1.9-2.0 bar is just not so, yes it would need a
different intercooler, manifold, exhaust, etc., but the turbo could
supply the air. Also notice that the stock K24 maxes out at a lower HP,
so I doubt that if absolute max power is the goal that a stock K24 turbo
would help, it does spool faster, but at the limit can not supply as
much air as a stock K26 at the limit.
