Your best bet would be to get with a vendor and explain your situation. Once you got that down check out some online places like Parts taxi to find a Stock Throttle body and have it shipped to the vendor of choice. That would supplement the core charge and actually be cheaper than paying the 200 they would charge if you kept yours. And then once your receive your ported one you can keep your stock one just in case.
