If you want to be competitive in SMF you have to have Rcomps, coilovers, and a good rear sway bar, but if you are just out their for fun that who cares what you have. I would suggest doing a couple of events or even the rest of this year to get a feel for the limits of your car. AutoX isn't about power. Suspension and driver mod> than speed. The first year I raced in STX with next to nothing and had a blast. The year after I did springs and sway bar in STX. Then I went to SMF with Coilovers, Rcomps, header, and ported intake manifold. I still run stock boost with a tune, but this year I have 255's in the front and 225's in the rear. You don't need massive amount of power. The nice thing about SMF is you can lighten the car up a little bit. The cars that will give you trouble are the small little civics that have a crap ton of suspension in them and running high boost. Their small wheelbase and power to weight ratio are hard to beat.
