Paul,
	I am surprised Mazda did not provide you with a rev limit built into =
the ECU with that package.  One note of caution about aftermarket rev. =
limiters which cut out spark - you may overtemp your catalyst by sending =
large quantities of unburned air and fuel down the exhaust.  I haven't =
personally seen this, but I am used to fuel shutoff type rev. limiters.

Can somebody give me a quick tutorial / goto
on rev limiters.  I broke a vavle spring in my=20
323 GTX this weekend running it up past 7.5 K once
too many times.  I want to add some safety for my motor.
It is a 4 cylinder turbo motor from mazda.
