I have a 3.7 DOHC from a 2011 Mustang that I am transplanting into another car. I know of a 3.5 Ecoboost that is basically a parts engine. I may be able to buy the exhaust manifolds and turbos from it. Will the manifolds and turbos fit my 3.7 (I think they will). What would be a fair street price for the very used manifolds and turbos? Thanks.
