Just be careful, you're playing with a lot of potential damage to your motor when you to forced induction.

this is not correct, the h23 makes a better N/A build; this is because the longer stroke. If you were to turbo the h23 then you can run into rod snap issues.....as the forces coming down on the longer rod cause more stress on the rod therefore causing it to have a higher failure rate. Stock h22 are not meant to be turbo'd; look at the position of the piston rings and you will see that, the rings are located much higher on the piston.
if you want to build up a crazy NA monster then use the h23 w/vtec(good luck finding a timing belt and oil sending unit, among other things...lol), if you want to turbo the better engine would be the h22a4. As long as you build all the parts equally you will have no issues with the turbo. Like i said before a well built turbo build is goin to be much more reliable than a well built NA; this is due to the lower duty cycle of the turbo engine. any way i am just repeating my self.
lastly, the stock transmission is good for about 550 hoprspower and around 400lbs of torque, pending the proper clutch setup is used. as for the axels you can get heavy duty ones but you are looking at a very stiff price, like almost 5 times the amount as a stocker, use the stocker till it breaks then change it out with another stocker(did this with a b18 and it was just as good and much cheaper than the DSS ones). If you are looking to have your trans souped up also then really all you have to do is get carbon syncrodes and get a beefed up LSD, and be johnny on the spot with your fluid changes.
