Mk1 Focus RS engine in S2
 

Hi all, when fitting a mk1 focus rs engine into a mk4 do you follow the same guide as blacktop Zetec install?
Couple of things I’m wondering..

*Wondering if you can stick to the focus rs auxiliary belt set up or you do the same as the blacktop and add the other pulley and long belt.
*can you keep the original focus rs front breather set up
*is the engine mount mod the same as a blacktop.

think that’s all I need to know.
cheers
