BOLT ON MANIFOLD FOR A3

[Quattro colin]

So obviously there is darkside bolt on manifold to allow the GTB turbos to be be fitted but these are well over £ 1000

so I've been thinking that there has to be a manifold that will bolt on?
such as manifold from all the othe engines n I'm thinking the a4 mani

I know there will be some custom work but this is gonna be cheaper than darkside 900 quid mani
