so if i am right, i am fitting a 2.0 zetec to my S2 BTW, a focus rs box flywheel clutch kit will pop on and uses the cable selector? is it a cable or hydro clutch and one more thing i guess it will fit either black top or silve top blocks as the are essentially the same only differance is really in the head and cam tensioner if my research adds up.

please correct me if i have it all wrong, i normally do.

i have considered a multitude of box options and keep coming back to the rs option has it seems to be the most cost effective solution without compramising.
