If it's a fuel pump problem, it would NOT work fine when at full throttle (when the flow is higher). Same with spark plugs. Higher power output means higher cylinder pressure, which makes spark plug gap problems worse, not better.
It's more likely something like a throttle position sensor that is going bad and isn't functioning properly at the angular position where it starts to break up.

Check all Ur Ground Wires. I also have a 00 em1. i did the very exact same thing as u as far as plugs, wires, rotor button. thought it may have been the problem (wasnt) . Next thought it had ecu problem (changed) but still did it. this may not be your problem, but after checking everything it turned out that my dizzy was taking a shit. i replaced ignitor, and coil. and ran fine after that. hope it helps may not be a bad idea just to check that.

Re: 2000 honda civic si breaking up
Just something else to throw out there, most hondas these days are running the shitty aftermarket "TD44 and TD84" stickered distributors that come from places like bapgeon, ect. Those distributors have poor quality internals and can cause all sorts of issues, but still work. Your typical life span on them is about a year or so of daily driving before they start screwing up. Try borrowing a friends distributor and see if the problem persists. It's free and easy.

Update:
While tinkering with the car today I noticed the breaking up occurs around 3500rpm most frequently. Also the top sensor on the throttle body (can't remember which it is) came off of the stock b16 which would have this issue every now and again. I didn't get a chance to completely disassemble the distributor but upon removing the cap I didn't see anything out of the ordinary or anything broken within the cap nor anything out of the ordinary inside of the distributor (what I could see inside it without removing it and taking it apart.
Can the top sensor being faulty cause this issue? Again I don't recall whether its the MAP or MAF sensor that's on top
