Porting
Try to do a search in the members section for Steve Monroe, I think his member name is (stevemon). He did some porting work for me, I was impressed with the quality of the work, also he did not charge an arm and a leg for his work. Most of the work he does is on throttlebodys and downpipe elbows, however he told me he can also do turbo housings. Contact him it will be worth it.
