My 4runner '94 V6 3L is stock as far as I know(motor wise), only has a Lukey branded muffler. I was thinking of doing the following mods: Supercharger (dont know what fits, also need a little help) Upgrade ecu (or flash tune, whats better??) Extractors + High flow cat is there any other mods that I could do? And is there any other factors that i should take into account.
