I have the 2.0. recently what i have done to is simple. intake, headers and exhaust. but i was planning in the near future to rebuild that engine, pistons cams rods etc. i was hoping to find someone who owns a mazda 3 and has an idea of what i need to look for,
i have an automatic transmission bcuz i wanted it for a daily commute of 1 hour...but i really want to start to kick it in gear and start to really build it. i was wondering how hard it is to do a tranny swap from auto to manual..i know it would just be easier to just buy a whoole other...
