Hi people

Just a quick query....I got a fiesta 1.3i, year2000, bought it with head gasket gone, stripped it today to find the exhaust valve seat dropped keeping the valve open, and No4 piston is badly wounded and burnt away right on the edge...basically you can see the top ring...luckily the bore is untouched.but..instead of messing about I thought I would just get another engine for the car, this is where my question comes in

After looking for an engine I keep seeing endura and Endura e engines...whats the difference and is the engine the same in the KA as it is the fiesta or is there slight difference's

Please help before I commit to buy
