are there any performance parts on the market for these motors? besides your basic air filter or cold air upgrade, i know of corsa exhaust. what else is available off the shelf?? anybody make headers or port heads or have cams available to install??? what about computer upgrades? i assume ignition is pretty good so we won't worry about that.

there isn't TOO much....

check out RSM (link on top) they have a cold air kit, ported heads ($$) supercharger ($$$$$$$$$$$$$$$$$$$) and a few other things.... IIRC there are no computer chips becuase any car '96 and after uses OBDII
