can someone give me a lowdown on what a zvh consists etc etc! basicly a basic expliantion of what it is!

thanks

 

CVH head with a Zetec bottom end.

is it as simple as that!!!!

does it just bolt together no messing! or is there some modifying to do?

 

If you're running it for turbo application you need to drop the compression to suit and ideally the head needs somecarefull working to prevent the power and torque vanishing past 5.5krpm

Its all there!

 

Dont do it lol
ZT or CVH....

 

nowt wrong with zvh pal, but if you're starting from scratch, then zetec turbo all the way.
my zvh is quite quick and i'd say for horsepower the cvh suffers as badly it's just the power comes in much earlier in the revs than a cvh which is why it won't rev as far, mainly due to ports in head.
i'd love to see a power curve comparisson of cvh vs. zvh all the way to 8krpm and see how they really vary at the top end.
i've only seen the drop off at 5.5krpm on a zvh and yet to see how the engine responds higher up.
what you must remember is that a zvh is a very torquey engine and as such is a bit diesel like.

 

im not converting i have just bought one with the engine gone bang that was converted to zvh already! so i was wondering how it worked as i was gonna get the engine running again!

 

if that's the case, find out what let go and replace/rectify.
i'm running peak of 21psi on mine and no point trying to grip in the wet till fourth gear.

 

I would say this would make one brilliant at blasting round the B roads.

 

im led to believe its the bottom end gone (chucked a rod!) but im sure there will be head damage too!

 

ive switched from cvh to zvh and wouldnt go back, much better road car, my head etc is slightly fettled tho so cant comment on one running a standard head

 

which block gets used mainly?? is it 2.0 or 1.8??

 

1.8 or 2l i spoke to a lad at si tec who said if i used the 2l with standard pistond it would be low comp enough for boost

 

i wouldn't run much boost on 2l pistons though, the 1.8's have much thicker crowns on the earlier ones and can handle boost better even after a amsll skim.
as said a zvh has a massive surge of power that the cvh never seems to have even with a wild cam or big turbo.
can't make a replacement for displacement
