i had an 03 civic si. i did the jrsc just because it was my daily driver. i just sold the civic and it had 90,000 miles on it. about 75,000 with the charger on it. you wont get as much power with the sc, but they are often more reliable than a turbo. i also know of a guy that does the cams for them. as for the other internals. i couldnt find them , but i know they are out there. there is a web site/ forum that just has people with that style civic. several people on there have torbod civics. and someone might know about internals. its called ephatch.com. hopefully somebody from IA can help , but if not that would be the place to go for info on that car.
