OK, just been reading a post on RSOC about ZVH's, now everyone says you can;t get 300 bhp out of one dure to the CVH head not being able to flow enough air. Thus the major limiting factor a any CVH could well be it's head.
Now you can fit a CVH head to a Zetec bottome end (you have to block off some oilways, change the crank pully etc) and it works. Now my question is, can you fit a Zetec head to a CVH bottom end?

It seems, pretty straightforward - instead of fitting everything off a CVH to the Zetec, fit everything off the Zetec to the CVH and block off the oilways in the head instead of the block.

[chumkila]

it is an interesting thought.

LOL@the RSOC thread.

[grahamb]

I'd have thought that you could fit the head no problemo, but whats the point?

The Zetec bottom end is used because it's stronger.

You may as well just fit the whole Zetec engine.

The reason people keep the CVH head is because it then retains the manifolds, turbo etc etc.

[bcracknell]

just curious about why it's not been done (or has it?) it'd be like a sort of opposite ZVH......could be fun..

[chumkila]

you could call it a Cetec??

[The Bruster]

grahamb..... took the words right out my mouth!

[MadcatCraig]

the limiting factor even in zetecs is the head

and problems getting over 350bhp with a zetec head

thus u need a new better head

[chumkila]

its just about gettin the flow right with the right valves etc. it can be achieved using the zetec head.

[bcracknell]

at least it'd bring the bhp limit upto around 350bhp... plus you get 16 valves, and not much to change. hmmmm already got a sorted 1.9 bottom end.... could have the first 1.9 Cetec Turbo.
does the FRST EFI inlet line up ok on a zetec head?
I know the exaust has to have some extra holes drilled and tapped - not a major problem... c'mon guys lets hear you thoughts I may try this come the new year

[chumkila]

yep the FRST EFI inlet line will be ok on the zetec head but it will needed to be modded somewhat to run power anywhere near 350.

I think you should give Ian Howells a bell this evening

[chumkila]

If you ever forget his number, it can be located at http://www.zetecturbo.com

[MadcatCraig]

the frst inlet does not line up with a zetec head

an adapter plate is required

Ian Howel sold one to B19 TRB he has a black S2 and has a 16v turbo in it
this didnt fit at all as he posted in the general section - this plate cost him £35

the best thing to do is get a cvh gasket and a zetec gasket see how they line up and get a plate made.

a Zetec bottom end is stronger than a cvh

the crank is larger and stronger it has a high pressure oil pump oil spray jets alloy sump etc etc

10 years of engine development speaks for itself

[chumkila]

Craig was it not the gasket that didnt fit on B19-TRB's??

[MadcatCraig]

well sort of chum

when he was round mine last week he said that the ports on the gasket dont line up, thus the ports on the plate and head dont line up.

anyway £35 for a plate i think thas a joke

get the 2 gaskets find an engineering company they will make you one for a tenner cash

[sunnyFRST]

pimsle! - If you think it's a joke then why pay for it and instead didn't you lot make it yourself at home like you said in the post above + if it's as easy as you say it is not disputing that it's not easy however you should of made your mate one!
IMO £35 isn't too much money for it, the metal, the time to match the gaskets up and paying someone a score at a engineering company to make one up....£35 sounds very reasonable to me but then again people on here clearly know better.

Thanks - Sunny.

[MadcatCraig]

lol sunny why buy one when you know someone who has one, then which u can clearly copy

it cost me about £8 to have a waterpump plate made for a ZVH including buying the gaskets so i think £35 is a bit steep hey im a tight ass

was just a bit dissapointed when lewis told me his IH plate didnt fit

oh i didnt pay for it either

but make one of my own i will now i know wot it shoudl look like

[Mexi]

probably costs that because of the development that went into the adaptor plate in the first place

[Andy'sFRST]

It costs £35 [ERRR] its made out of aluminum thats about 20mm thick, and just for the aluminum is costly by itself.
A water pump plate for a ZVH is made out of mild steel and is very cheap to make.
£35 for the adaptor is a good price, if you want to make one yourself then take a Zetec inlet gasket to a machine shop and ask them how much it will cost to make a copy of the gasket in aluminum 20mm thick.
May cost you about £40-50.
The reason Ian sell them for that price is because he has about 10+ made at a time to save on cost.

[Ian C70T5]

It aint a rip off thats for sure..

Plus i dont think he would like people copying his designs

[MadcatCraig]

my zvh pump plate was made from ally not as thick as that mind

this need not be an argument if it had fitted correctly i would have no problem but it didnt

you spend your £35 i will have my own made

[Andy'sFRST]

my zvh pump plate was made from ally not as thick as that mind

I was talking about the inlet adapter being thick not the water pump plate

[Ian C70T5]

I'm not using any plates!

[Project]

Ian,

I bet you're using the Series 3 Focus inlet manifold with FRST injectors on the Focus fuel rail, aren't you?

Otherwise, how the fap???!

Craig,

You? A tight-arse?!? Noooo, I won't hear such lies

Peace out and Merry Crimbo folks

[Ian C70T5]

nope

You'll see if you come round an say hello
