here is how my engine looks again. im using a subaru intercooler to match the boxer engine and loaded with turbosmart stuff like BOV and also external wastegate. Notice that there is no air flow sensor? well i have remove it because im using haltech EMS to manage the engine and also a MSD ignition system to do the ignition job. Other then that, intercooler piping is also fully stainless steel which is done by the same guy that do my turbo manifold.
