anyone know where i can read up on this?
or maybe just any engine into a focus?

reason being my mate has a Focus 1.6 and hes getting bored, and i am used to fitting big engines into Vauxhalls (i own a Corsa 2.5 V6 Turbo with NOS) so i said i would look into it and ask about....?

i am planing on going to the RS owners club day and ask and maybe have a look at the lay out etc and maybe have a chat with a few owners....
