I know that it is very hard to find parts for our cars especially engine parts. I know that these accents will never be fast but are there any other mods besides headers and exhaust, and intake that anyone has tried to increase hp? Im talking about cams and increasing piston bore and such things. Right now I have only heard of the kit from import performance which includes pistons and gaskets Import Performance Parts - Hyundai HP Engine Kits. Has anyone experimented with this yet?
