Hello can anyone tell me if genuine ford focus rs head bolts fit a silver top zetec turbo as I'm fitting a frs head gasket ???

And someone told me you can play around with different ford cams to get more driveability ?? Which ones??

Mines a 2.0 silver top

cant rember on the bolts.

Yes you can fit say 1.8 blacktop cams into a rs engine as for knowing what it will do i dont know but i read about a rs in performance ford awhile ago using a 1.8 inlet cam iirc with 500bhp and he said it created more bottom end.

Yeh I hear they work well with the inlet cam change

I know the silvertop head gasnet fits the blacktop. I did that myself so I dont see why it won't work other way... As for head bolts surely as head gaskets are same they should fit..?

they should fit, i'm not sure on silver top cam swapping, i know blacktops can be mixed for varying performance changes, i'd assume silvertops would do the same.

This is an old thread, mines already built now

I used focus rs gaskets and silvertop bolts and new cambelt and water pump ect and fitted devil developments valve springs while it was apart, just need injectors and a turbo and then I have everything

yes you can, bit late no as you have done it.
but the FRS head bolts and MLS gasket can be used on the silvertop. blacktop i am not sure as never done one.

I used genuine ford gaskets

Wish I fitted steel rods but just wanted it back on the road

Std rods are good for circa 270bhp

i know i was going to aim for 300bhp but decided to settle at around 250bhp and spend money else where, like wheels, brakes and suspension ect

they can always be done at a later date bud when the rest of the car is up to it

Yeh, tempting to build up a spare block

Turbo Zetec

all zetec (and duratec ST/RS) headgaskets and bolts are interchangeable really, most companies only sell 3 layer MLS gaskets (0.6mm thick) to fit all late models, but there are thicker ones available.

you can fit a black top gasket onto silvertop and if you really wanted to (although i have no idea why you ever would), you can fit a silvertop gasket to a black top.

Bolts are the same on all models.
