text: i would about twin turbos set up on a 4 clinder engine 2.2?   it has rarely, if not never been done before. twin turbo set ups usually work with very small turbos, with one turbo spooling initially, and the second turbo spooling at higher gears/rpms. i suggest a single turbo set up, as it conserves space. i cant even imagine what a twin turbo manifold on a 4 cyl car would look like.
