Cheaper and better? Who and what is wrong with there quality? I have had manifolds, radiators, header and oil tanks off them with never a problem in quality. There parts are extensively race proven. They also offer throttle bodies if that is what your after.

by better i meant cheaper ;) bogg brothers are notoriousley expensive when it comes to tb set ups, you can achieve the same qaulity and power elsewhere for a better price, they seem(from what ive read and heard) to charge every manifold they make as a "one off job"..... even when theyve made and fitted the same manifold to MANY other engines,

and to the op, custom pistons from any vendor wil not be cheap
