right,if your using the 1.8 stuff u can keep the clutch and flywheel,its the same splines as the CVH box,so its easy!.wiring wise i had this loom last year in mine,buts its pretty easy again,u want a zetec without PATS really and u just got to find the powers and earths,haynes does help with tht bit!
performace wise,well,its a jump, the zetec runs so much smoother then the CVH, it responds lovely and looks good in the bay, this wasnt really done to go fast, it was more a modern twist on a 80s car,well 1990,lol,best thing of all, no more CVH tapping!!!!!
