does anyone know approx. how much a setup like this would cost????? It says: MODIFIED WITH A BALL BEARING GARRET TURBO, FRONT MOUNT INTER-COOLER, EMS COMPUTER, BLOW OFF VALVE,2 EXTRA INJECTORS, TURBO BACK EXHAUST,FRONT MOUNT OIL COOLER. Doesnt seem to metion anything about heavier duty internals......Does this mean you can run a turbo without touching the internals???????
