turbo charging a v6 5 speed

[cardboardpimp420]

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

There are no modded ecu's for the Mazda 6. Nobody has cracked the CAN BUS that the PCM uses. You will have to use a Greddy E-manage or something like that.
