is a focus rs engine and a focus st170 engine the same engine but with a turbo? i.e do they have the same mounts on them? would parts bolt straight from one to another? they are both duratec arent they?

any help appreciated?

cheers

 

not the same st170 has vvt and st has a much better head.

 

are the engine mounts the same? do they have the same mouting points?

 

Yes, i believe they are

 

Not even nearly the same mate different crank, heads, pistons blah blah blah

 

What's different about the crank? I'm very interested!

 

Is it not just a stronger crank,
