My Camaro is TT and unless you knew what to look for you would NEVER know. I am SERIOUSLY debating putting the stock airbox back on to hide the intercooler neck. That is the only giveaway. Stock engine except for pushrods, valvesprings & fuel system. 7psi and I put down 524rwhp. Yes, that is to the tire so closer to 600HP at the engine. I have shocked my share of subaru's out there. They all think I am stock until they hear the turbo's spool and that smile on their face turns into a huge OH $&#T! :roll: Car has a normal rumble and my mileage stayed pretty good as well. As long as you stay out of boost the mileage is good. I have 4yrs and over 30k on the set-up now. Just run premium fuel, get in and go.

It's not a cheap endeavor to go forced induction. So do your homework and budget for it and stick to your plans. It is easy to get sidetracked and go over budget. Good luck! I saw a bunch of F-bods for sale over on mifbody.com.
The power levels will break things so if you find a car with an already upgraded rearend, you will be a few steps towards keeping it reliable. Like I said, do your homework.
