have you done the beginning stuff, intake, header, exhaust? After that maybe cams, rockers, tuning, etc.

Your car is an inline motor, not a V. It doesn't have heads. It has a head.
Get an eBay intake. It's all just a piece of pipe with a filter at the end. When that filter goes bad, get a K&N.
Also, get a Megan header. You can get a DC but the Megan is the same or better quality at a fraction of the cost. The RSX guys go crazy over Megan parts.
Then get a Magnaflow high-flow cat and the exhaust of your choice. Custom or a cat-back.

Crower is the only company to make H23 cams. Anything beyond stage 1, you'll need new springs, retainers, and valves.
If you still want to go further, the stock manifold is actually really good. You can port it and also get a bigger throttle body for it.
Finally, get a good tune and enjoy. Don't forget to upgrade the clutch though.

fuel pressure regulator, and i dont know if they actually work but try a throttle body spacer...and if you want to go crazy; lighten flywheel, swap gears, bigger pistons, and all that shiz

Not much if you don't build the bottom end to compensate.
Do research before you buy anything. Search search search. If you can't find an answer, ask. If you get flamed, one of us will take care of it. Just do yourself a favor and have a set plan of attack and stick to it. Do it once, do it right. Don't be one of the DEI geniuses, lol.
Tip though, to bump compression, just use some JDM H22 pistons (10.6:1 compression) or Type S pistons (11:1). If you get the block honed, you can use oversized Type S pistons and start on fresh metal.
TB spacers don't do much, if anything on our cars. Don't bother.
Your stock ignition system is fine. When you get then whole engine built, you might want to consider upgrading it but until then, don't worry about it.

It's a joke that's circulated in the automotive forums for a little while now. The site took the link down because it was getting so much traffic and slowing the rest of the site down.
It was this guy who had 15 second Corvette who thought turbos were so inefficient and made a diagram called Direct Exhaust Injections (DEI) and thought that buy routing his headers back to his intake, he would make more power and completely bypass having a turbo or intercooler on the car.

This is the drawing he made. Someone just put it in one of them motivational posters, lol.

Right. There's also companies than can make regrinds but I've never heard anything real promising about any of them.

Alright.

1. What are your goals for power, torque and horsepower wise?
2. What is your budget? All motor is expensive.
3. Header - please, not headers.
4. I'm not sure what you mean by hp ported head. I have a h23a1. I have the basic akimoto intake, dc-sport header (buy a megan), and a custom 2.5" exhaust with no cat. Recently, I had the valve seals replaced and decided to slap on a ported and polished head. To be honest, I couldn't tell a difference.
5. I ran across this site and thought it to be interesting: http://www.importtuner.com/powerpage..._se/index.html

I'm not sure if any tuning went on b/n dyno runs, but that gives you an idea on what the basics can do porbably with a proper tune.
6. In my humble opinion, I would build a nasty turbo h23, or build a monster N/A h22. The h23 takes advantage of the longer stroke producing more torque for a turbo kit.

I have devoted most of my research to turboing h23s and the n/a side is my weakness. At first I thought I wouldn't want to boost, but I just wanna hear that Psssshhhhh sound now.

Pfft. If I hadn't found such a good deal on my Crowers, I'd be running Delta 260's right now. Can't beat $93 a cam. Anyway, just copy my build and you'll be golden

Noticeable. Not just in power, but you should hear it growl at 4.5k. Honestly, the only things I wish I did differently (or simply added on) would be a thin head gasket, and a P&P manifold
