172 turbo manifold ?

hya i am part way threw my 172 project and i am sticking with making it turbo ;) i was just wondering where the best place would be 2 get 1 made up so the manifold bends round the side of the engine so that the turbo sits above the gearbox,

iv seen a few on some threads and they look the part plus it spreads abit ov weight :)

thanks alot
