1.8 zetec head onto 2.0

Gregor · 06-12-2009, 08:22 PM

After lifting off the head of my 2.0 silvertop zetec turbo i found the camshafts were somewhat damaged along with the head due to pollution in the oil i think.
As a matter of course also removed the rods and the crank is also on it's way.

No i can get another crack here from a 1.8, should be the same but can't seem to find e decent 2.0 silvertop head.
Now i was told a 1.8 head will fit fine and the only difference is the combustionchamber is a little smaller.
But what about running the 1.8 camshafts on a little modifies 1.8 head go on this?

Or anyone got a good, complete silvertop head perhaps ??

Thanks.

you can fit the head, but will raise compression ratio, N/A boys do this with the zetecs.
but it will work though.

Thanks,

The chambers can be worked on a little to get the same cr i guess but how do the cams work , better/same or worse then the 2.0 ones?
And are the ports and valves the same size?

I'm pretty sure there isn't much in it but i do know the cams in the 1800 are a bit milder than the 2litre.

depends on what the 1800 head is off, you can use the 130 spec cams from the 2.0 without problems, i'd even say the ports/valves are the same, but you need to get teh 130spec head though, so escort gti really.

The gti didn't run the 130spec 1800- it was a 115ps version in the mk6 models.
130spec 1800 was only fitted in the mk5 xr3i officially.
115ps 1800 has milder cams- the 1800 130spec/2litre cams are one and the same.

cheers for that, wasn't entirely sure which ran 130spec.

Oki thanks guys,

Will be looking for a 1.8 130 bhp or a 2 litre head then..

So Just a quick question then is the 1.8 XR3i Cams and the 2.0 Cams the same and what about the XR2i Camshafts?

1.8 xr3i came as a 105ps and 130ps, only the 130ps version has the cams that are the same the 2litre zetec.
i think the xr2i came with the 115ps cam setup as the 130spec ones where reserved for the fiesta RS1800.

cheers so am i right in saying the rs 1800, 130 ps xr3i and 2 litre zetec have the same camshafts
