turbo or supercharger either

If you own an NA Miata 1.6l you should make sure your crank is the updated one first, the keyway is prone to failure on the crank pulley/timing gear. Those engines will hold up to a turbo pretty well being forged internals from the factory. It's the same as the 323 gtx engine basically. If you are not going over 8-10 psi with a properly sized turbo you should be fine if the engine is healthy.

[MrMiata]

any brands you would recommend for the upgraded crank and pully system?

Forged internals from factory! I don't think so...
Get yourself on miataturbo.net there are some great FAQ's on there. Its a great engine for boosting, just do it right with a nice kit and you'll be making good reliable power.

I'm in the process of boosting the B6, but in an MX3. Should see around 170hp.
