You only need a slight mod to get a certain Ford kit to make it fit the XR2 a la my old 'bay about three and a half years ago...
PS. Check the Samco profile in this months PF Mag. Their hoses are pressure tested and on our visit a standard boost hose withstood 60bar (870psi) before it popped, they are guaranteed to 10 bar though so not sure many T3 or T34 turbos will be bursting any through too much boost, do you?
Also the thicker the hose is the less flexible it is and the heavier it is, if they are made right it's no advantage.
Oh, and you don't deal direct with Samco if your joe public it's one of their dealers you'd be talking about so try another dealer if your usual one doesn't have the hose you want in stock... Just an idea lol
