    300SX Rev Limiter?

    Does anybody know anything about rev limiters on the 300 engines?
    I can't seem to find any threads talking about the 300's rev limiter or how to bypass it.
    I have a maintenance manual that mentions the 300's past 1990 have the rev limiter built into the CDI. I am assuming nobody has ever made aftermarket CDI's for the 300's to bypass the rev limiter, so I was just seeing if anybody knew of any tricks or other parts that may work to bypass it. Mine 300sx is a '91 btw.
    Thanks

    Is it like the 550sx's where you have to remove one wire or do you remove the whole unit? If I remove the whole thing will my stop switch still work? I remember that was a problem on the 550sx's.
    Thanks for the reply btw
