adding power to my civic si!!
hey i just got a civic si, with a Gsr engine and a b16 tranny, the only add that the car has is an intake... im trying to get more hp and tq without going turbo... help me out, give some ideas!!!
this is the list of what im tryin to do:
mds external coil
header
intake mani w/ 65 mm tb
High flow fuel rail
fuel pressure regulator
and probably add a s200 ecu
and get it tune..
so give some advices about all that, and u know tell about some other stuff i can add to it...

how many miles on the GSR? if u want power without boost, i hope you got deep pockets. reliable engine builds are expensive so jsut keep that in mind.
i would recommend what i have which is a poor man's type-r. you're gonna need a b16 head though which you should be able to afford when you sell your GSR head to someone who's trying to do an LS-VTEC. lol. and type-r internals for the bottom end.

You don't need a fuel pressure regulator, especially if you're getting something like the S200. If you need more fuel flow, get larger injectors. Stock fuel pressure is fine.
You definitely don't need a high flow fuel rail, because you're not going to come close to what the stock rail can flow. Buy one if you like the way it looks, but you aren't going to need it.
I'm not really sure why so many people immediately buy a fuel rail, regulator, and bigger fuel pump when the stock system works great for most non-turbo use.
You'll add a few HP with the intake manifold and header, but above that you'll need to affect engine efficiency with something like cams or greater compression. Minor external bolt-ons can only do so much, because they don't really have much effect on what happens inside the engine.
