Hey guys and gals, doing some more research for my friend. Ok he was going to get the MRT FMIC, but it was sold yesterday So he'll now get the Greddy FMIC at Titan Motorsports. He has the Blitz BOV right now, will he need to get a Flange and do any welding? Would installing the Greddy BOV to this FMIC be easier (like my setup on my Silvia). Help!
