also u can relocate the turbo more towards the bumper and get a vent in the bumper so it'll have air cooling it from the out side. you don't have to leave the turbo right off the header but its a bit pricy since they don't make kits to relocate the turbo u'd have to get the piping bend it and weld flanges on it. I ran a mustang twin turbo and we put the turbos right behind the grill the incoming air helped cool it down. u can even put the turbo up be hind the bumper just watch you're ground clearance and don't have it right up close to the bumper or you will melt it.
