im currently building a diy turbo kit. i just want to get a kick out of the 3.8l i got. just want to find out how much boost can safely be run on a 2001 stang w/auto trans with the factory tune and the factory fuel set up. i have heard things like 4.4psi. just want to be safe about it and also about how much hp should it make. currently got a t3 turbo given to me for free from a friend of mine. working on the turbo headers now. will try to post some pics. only upgrades done to car are dual flowmaster,65mm throtttle body,airintake. thanks for help
