Just as a matter of interest; we are out of the 50mm custom intake runners, but I sold my last set to a guy with a big-bore 12v project, so we modified the intake plenum utilizing two standard Milano / GTV6 intake plenums!
I sectioned the one off center-left and the 2nd plenum off center-right and had my TIG guy weld the two larger halves together. the bottom was jigged off of the position of the standard runners and then we made a brand new bottom plate, machined rings and welded them on, radiused the inside edges of the down-stubs and welded the bottom plate to the new plenum.
I had it finished in a 2000 degree thermal heat-barrier coating and now the customer can just source some 50mm silicone tube to cut his connector stubs and buy some nice T-clamps!
I figure the volume is about 40% higher.
