The MBC modification is also of no use to T7 based engines. For low cost mods that will improve the airflow for this motor look into other mods at Eric's site such as tweaking the throttle transition casting (and also porting it at the other end to match the manifold) and improving the airbox by installing a K&N filter *and* putting a 3" intake on the front of the box that will pull *cool* air from the bumper area. If you want to spend some money, a sport exhaust will help at the other end. You can also go the ECU update route but that's getting into big money. There are also lots of things you can do to improve the handling and suspension if you are into it; price start at $100 plus labor and it goes up from there depending on who's labor and what mods.
