i wont drop "straight in" no, but it will go in to a puma, little bit more work but in the long run its worth the extra spend, its a very tunable and reliable engine. check out pumanoobs car.. he's done it.
you can run good power from them, but the art comes from running the right amount of power for the car, theres no point having say 400bhp if you can put it on the road, the idea is to find that balance between drivability and performace, master that you'll end up with one hell of a car, id say 300bhp is about the moust your going to want to put through any FWD car, Errol (duratec turbo FRP) has around 340bhp and says its too much for the car.
Cost wont be cheap to do the Duratec conversion, with turbo etc but if you can, build and fit the engine yourself you'll save alot of cash, biggest cost is ECU, wiring and mapping.
