I don't have a price yet Jon. I'm having a test flange cut at the moment then I need to make the runner and get it all to the welders. The cost for materials is low but does have quite a bit of labour time. I expect the head flange and support flange to be under £40 but probably around £60 for 2. Runner material is next to nothing (£30 for 3m length). Welding will be around £80 as an estimate. You will need 2 sets of throttle bodies to make up a 6 bank and they are around £250 each. With these you do get everything you need such as injectors, TPS, cable linkage, MAP interlink pipes, fuel rail, and trumpets. These are easily reassembled as a bank of 6 using 5mm studding.
