difficult job but can be done to most cars,ive even seen suzuki vitaras with a 300bhp yb,you name it,its probly been done,a cossie yb would be easier though.BUy a complete 2wd or 4x4 damaged cosworth for £2000 ish,then get a cheap motor i.e a £250 1996 manual mk6 escort,then strip both cars,cut out all the parts from saph that you need i.e floor pan etc.make parts like diff hangers etc.and you will need a escort cossie prop(length of escort)2wd diff,t5 gear box if 2wd,yb turbo engine(best engine to use)any more info PM
