I only have and AEM cold air intake, H&R 1.5" lowering springs, and B&M short throw on my '02 ZX3 and I only lose by half a car length in the quarter to my friends SI.
His SI is a '00 or '01 with AEM cold air intake, 5zigen catback, short throw shifter, Yoko's, and lowered 2".
I've whooped up on another '02 ZX3 with full flowmaster exhaust, short throw, ram air intake, and the 2" Eibach lowering springs.
Or maybe it's not my car, and I just know how to drive?
Hope that gets your hopes up.
