Turbo 07 GT
#3
Brenspeed did some videos on youtube. They bought a high mileage stand 2007 with a 110,000 miles. It was a clean car and they did a variety of bolt ons and made 350hp. I don't think they added a power adder but like the poster stated above check compression. I think that shop did a high mile coyote build as well. They took the cars to the strip and raced. They hold up fine.

07 NIGHTMARE, If your stock block checks out, like Deno said, I would start at 6-9.5 boost. Now remember, there is a ton of other upgrades that must be done if you go above the 6-9.5 boost, ie cams,injectors, added cooling, etc. Now, if your 4.6 has been properly upgraded, and prepared for the turbo, I would not go over 14 psi of boost.
