Welcome.
i have some basic bolt ons like a joe z intake, hks carbon ti exhaust, megan headers, and an unorthodox cam gear. i keep debating on supercharging it but thatll only land me about 300hp to the wheels and since every company that made a supercharger for the is300 discontinued their product ill only be able to buy it used for about $1800.Welcome dude, you gona add any performance mods to your is300.. supercharge tha beast:twocents:
