Would require a hell of a lot of work, the flanges and the position of them isn't even close to what an MPS needs. They wouldn't close to 400 on a Mazda with out a custom tubular exhaust mani and after market intake manifold. The focus factory intake manis flow way better and even than the OEM Mazda.. damond Motor sports sell the focus intake mani kit to fit an MPS...But the design of the focus turbo and exhaust would need a shit load of custom fab work. Probably cost around the same to drop in an ATP Mazda flanged Garret gen2 GTX2867.. But 400 on a stock Block isn't if it will blow , it's when if you're into the throttle heaps.
