Unusual for a Zetec bottom end to go, they are quite reliable in standard form. Worth having a look to see if there is any damage. If you do need new rods, pistons and a regrind of the crank you may as well fit forged pistons and steel rods.
It might be worth speaking to SCT in the states, as it is possible to run a turbo on the standard ECU and sensors, i only found this out recently and im going to map my engine this way. You do need specific specs for your engine so SCT can write you a map though.
