Hi Rob,
Andy from storm - The cheapest way to get your piping would be from silicon hoses - as all ours have been made from kitsets we don't have any spare but i think it maybe benificial to get a 51- 76 or 80 straight depending on throttle size - then use a 76mm or 80mm straight tube then a 76mm or 80mm 135 bend to the throttle.
We have already talked about what you need on the intake.
As for the fuel regulators they are expensive at £149+vat but they do work and are specially made for the vr with Rotrex low boost - however you may be able to get a good deal from stealth on mapping.
Good luck with the install.
