i looked at AEM and it said all there stuff was for NA and i'm not sure about Skunk2...everything i seem to find is for a H22
what to get done to the crankshaft and the head?
Will this fit H23 or should i stick with stock?

Honestly I would stick with the OE crank pulley. My friend had an aftermarket one on his h22a, and he believes it was the cause of his oil pump failing (as well as doing some other damage inside his engine). The only thing I would do with the crank is to get it balanced, along with the rods and pistons together. For the head, I would get a mild P&P/deburring job. Find a good reliable machine shop and tell them exactly what you're going to use the car for (mostly street, mostly drag strip, mostly autox, all of the above). Otherwise they may go too over boards and take off too much material, and you'll end up losing low-mid end power. I would also recommend staying away from block guards, unless you get the darton M.I.D. sleeves that have them built in. The aftermarket block guards are made of different material than the sleeves, so they will expand and contract at different temperatures than the sleeves. This can end up messing up your sleeves, and ovaling them around the block guard (but not everyone runs into this problem). The OE fuel rail should be fine; it's not really necessary to get an aftermarket one. But the AEM stuff will be fine for forced induction, my friend uses their fuel rail on his turbo'd h22a with no problem. And depending on what you need to do, the AEM fuel pressure regulator will work fine. But they can only raise your fuel pressure (like most aftermarket ones), and doesn't allow you to lower the fuel pressure if you need to do that. Not really sure who makes valves for the h23.
