I've been searching for a similar combo but to no luck.
03 k20a2, rcew race header, rcrew 3" race exhaust, custom 3" CAI, stock a2 throttle body, rbc intake manifold, hondata IM gasket, stock injectors, 225 fuel pump, rcrew fuel rail and I'm currently not running any o2's.
Also isn't there a way to set the cel light as a shift light? I have an s2k cluster and when I drive my eg at night its kinda hard to see the where 8200 is. And what is the rev limit to the stock internal k20a2? I've heard 8000, 8200, 8600. That would really help me out.
