I was thinking of buying a 1.0s ecoboom with a broken engine, taking the engine out then replacing with either a 2.0 zetec turbo or a k20 turbo, both been done many times in the earlier fiestas with 400hp easily accomplished, but not seen any in the mk7’s think this could be done under a budget of £4K including the cost of the car.
If anyone has any links to anyone that has done this before please share
