I need advice

I just bought an SC and i wanna kno wut would be the first thing i should upgrade first. I already have an upgraded exhaust. I want sum more power, so wuts the best thing to upgrade to?

probably underdrive pulleys, and then I would go intake. Try a search for more information.

I would upgrade the intake system first,maybe then you could get a ported blower.If the exhaust is already done then you could also put a overdrive on your blower,with a raised top.I feel if you do not have the air flow to enter the engine then you will never make substancial power.
