Mario, in stock form from the factory in the car the 20B is rated to give

hp at 4000 rpm (turbo model). In stock auto form it has a 7000 rpm redline,
the hp dropping off a little (not much) at 6000 rpm.

Snip

 I have been looking for this kind of info on the 20B for some time,
where should I be looking?  What power at what RPM with what boost can one
expect from this engine?  From your above figures, I may want to change the
PSRU ratio.  299hp at 4000 rpm sounds to good to be true.

Paul, the local Mazda dealer had a Cosmos Owners Manual that I recall said the
20B was rated at 365 hp @ 6250 rpm. I saw it about 6 months ago, and I'll go
back and double check,

Bob, where did you get the 300 hp @ 4,000 rpm? It's all a function of turbo
boost, so we really need that number as well.
