you could always boost it that'll get you up to more than 200bhp though.

if you wanna stay NA, then do headers and an intake manifold next.

it just depends on your budget

a stage 1 cam, (larger injectors, new fuel map but wouldn't recommend), upgrade ignition slightly, headers, new mani, throttle body, advance the timing a tad. idk the 02 si wheel baseline so i don't know what you need

Buy a K20A(or K20A2) head, intake manifold, and ecu. Hondata ecu upgrades(K-Pro). Good name brand header, a 4-1 1 piece design if you could, exhaust, and a tune and you will be alot quicker than you think.

Get a DC Ceramic header for it, if you're not wanting to turbo i'd get hondata and possibly a new rsx head. Only get the rsx head if you're wanting to go 300+ horses though, if not and you want to stay between 200-240 its not worth it. On mine I have i/h/e plugs wires etc., but in the next few weeks i'm going to port and polish my head, and see what else I can do to get hp gains without doing forced induction. I find turbo'd vehicles (no matter how well put together the turbo kit is) to be unreliable and so I don't want that on my si. I dunno if you're the same though, turbo might be the right setup for you

I would definately upgrade your brakes before you increase the HP. Look at ultra light weight rims and rubber too.

def. get the 4-1 headers, and 3 piece pulley set you'll get into the power band a lot quicker. unorthadox makes a good set, also i had trouble beating people untill i got a nos sneaky pete nitrous system its only 30 shot. and from what i read 30 shot doesnt hurt the k20 ( correct me if im wrong).k-pro is the best way tochip your ecubut its $1000. a friend of mine has a ctr head and his gas mil sux 19mpg but you might not care.
