Hi all,

I currently have a 2.0zvh and wish to convert to zetec. I was wondering which head I should go for, silver or black top (or is this dependant on the 2.0 bottom end I have?

Cheers

 

I may be wrong but ive heard you need the same head as the bottom end.

 

a blacktop head can be made to fit a silvertop bottom end.

 

how does one go about identifying which 2.0 bottom end they have?

cheers

 

ah, so I would be ok either way. Is the blacktop the overall one I want?

cheers

 

Yes i think the black top is defo the way forward


prob be better just buying a engine than mixing and matching heads etc

Get a ST170 head

 

So, I've decided on making a start on this which will probably take way longer than anticipated!

With regards to the head, will the standard cams/head do? Apart from the valve springs of course.

I've seen a few different 2.0 heads, off focus's, cougars, mondeos (all blacktop) - would there be any difference in purchasing one off any of the cars above.

With regards to the mileage, should I be concerned with 70 - 80k milers? or buy mint new one?

I will have move questions as this slowly progresses.

Cheers

 

Alittle more info, I hope to go for around the 280brake mark. Current bottom end is on let pistons, turbo spec to be found out over this weekend. Will probably go cossie management

 

ive done a couple of 1800 zetec turbos (silver top) and one 2 litre ZVH turbo, was looking into the black top as a mate had one out of a mondeo, it is different on the block about the water pump area, the black top is a better engine as it has solid lifters that dont "jack" up like the ones on the early zetecs, hence the water thin oil recomended 5w 30! not sure about the vvt head off the st 170 though are they not chain drive and totaly different? plus there will be some serious complications with the control of the vvt. I would definatly try get the correct head for your block though, should be an easy enough swap. What manifolds are you planning on using? i modified the rail in one of my zetecs to take 444cc sidefeed injectors from a subaru, this was an escort xr3i 130 alloy manifold, and welded my own exhaust manifold up out of mild steel, both of which worked well.(1.8 zetec, decomp plate, subaru turbo, 204bhp and 214lbft @12 psi)
