Are you after boost hoses or coolant pipes?
When I spoke to samco regarding a coolant hose kit (years ago), they said they didn't list one, but if i sent a kit to them they would make it available. I may have a set of hoses that could be sacrificed if this is the case.
As regards boost hoses I think im right in saying they're 57mm internal and can be bought in standard straight lengths, 45's and 90's etc. Just a case of measuring up. The lower elbow to ic im using a chopped down 45 degree elbow, not perfect, but not far off.
