so i have plans on turbo charging my mazda in the near future, but i dont want to drop an incredible amount of money into it. No im not cheaping out on the kit, but im just curious if anyone knows the max "safe" boost i can push through the car without upgrading internal engine parts. also im assuming any kind of boost will push the air/fuel ratio off the charts so i was also wondering of any good places that i can pick up a modded computer for that. thanks
