the Mazdaspeed Protege intake and exhaust camshafts are the same as the regular Protege camshafts. You will see no gains this way.

The Mazdaspeed and JSpec camshafts provide increased lift and duration and are claimed to give gains of 10 - 12 hp.

Remember, "Mazdaspeed" was a independent tuning outfit long before they stamped the name on the MSP.

I would think so, adjust em, put the car on a dyno, tune it again until you hit the right mix.
