I want to get a 3" THDP for my mostly stock GN. If I get one with the 1" swing valve puck will it still work with the stock turbo with the 3/4" hole? I plan on eventually getting a larger turbo and I want the 1" puck to control future boost creep problems. Also, has anyone ever had one of these Jet Hot coated? Is a ceramic coating worth the money? Thanks.
