I have just put an rst engine in a fiesta mk2 and had to take engine from both cars and re fit into the mk2 fiesta and do the loom etc having never removed an engine before i can say this is quite straight forward, i also had no engine hoist all i had was a set of axle stands a jack and a set of steelies done everything all by myself.

If you had a driveway or could push both cars to a private car park i rekcon you could do it in no time especialy as both cars are identicle and you already have loom in there

£1200 for a simular job i must be in the wrong trade

Good luck with the reshell, is the best feeling in the world when u do it yourslef and can stand back and say "i did this"
