So the other day I picked up a set of two turbos for a Audi biturbo s4 I have all the oil lines and manifolds. Total cost for both was $150. So I'm thinking I'll put one in my 02 protege. The exhaust ports are oddly shaped so I'll have to make a custom manifold and down pipe, and tap the mbsp for the oil return? What else will I need to do and or make to do this? I'll have to get an intercooler but what kind air to air or air to water and where do I tap for the water lines? The turbos are a KKK k03 they run stock at 7-9 psi and have an internal wastgate that's run by a vacuume line I think where do I tap that to? Sorry for all the questions this is the first turbo I'll have done
