So I'm planning a project this summer for the S4. I just dont know where to put the turbo yet. I was thinking maybe the trunk? BTW thats not me in the picture.

Get a roof rack and a big rig wid visor on top, lol or you can do the American hot rod thing an cut a big hole in your hud and stick it up on the engine in the middle of the hood haha

if you don't run a wastegate you may get a pound or 2 of boost by redline in 6th gear....
