i have a escort mk6 (1997) and 2 of the valve seats have warped along with a piston. therefore i thought i might aswell change my engine. i was wondering if anyone knew if you could put a 2 litre zetec mondeo engine in a 1600 zetec escort. if so what would i need to change. ive heard the engine shoul fit almost straight in and run well with the ECU is this true?
