hi, i have a 1.3 16v engine (k11) in my mini, i want to turbo charge it, lookng at t25, intercooler and associated mods. what i need help with is making the manifold, because its in a mini none of the 'standard' designs will fit, i am very experienced in brazing and have now started mig welding, but i'm not sure of what tubing and bends to use and where to get them from, i can design and weld the manifold if i know where to get the materials from any pointers and links will be appreciated. cheers
