I'm personaly too new to these to comment but I will be interested to here what people say as I am just swapping a 2.1 ZVH for a high specced CVH. I've seen some CVH's with some bloody high power outputs though. Isn't the white APT ERST a CVH?

Originality and character
Sounds stupid, but it almost (for me) feels like going zetec is taking the easy option lol
Having said all that, I agree the zetec is the far superior engine, aftermarket management and zetecs are dead cheap now, compared to even 5-10 years ago when zvh's were more of the norm.

If your chasing number yeah.
I agree rob to me its much more impressive to have a 300bhp cvh than a 300bhp zetec.
Zetec turbo are great engines i dont dout that and i will be putting one in my next car. but i think if you have the money cvh

but wat about all the fabrication to make a zetec fit with the gearbox to take the power ! im sure the zetec is better engine so are zvh's pointless now or do they still do the buisness ?

no competition but just cant see why people bother with a cvh i cant see 1 benefit of a cvh over a zetec

The advantage of cvh is that it can make good power with minor mods not everyone is after 300hp. I agree that if your going for monster power then zt is going to be the way to go but nothing wrong with a good old cvh

yeah basially. and all the effort gone into gettting it to that spec. I am not saying cvh is a better engine im just saying they can both be as good as each other. but if you after monster hp ten the zetec will be the way to go.

Personally i still like to see a good old cvh or zvh lump as its more inkeeping with the cars era, zetecs are great mind you and seem easier to get big power out of

u can use the standard 1.8 zetec efi inlet
and an rs turbo exhaust manifold with a 40quid adapter plate
i admit u need to spend some cash to make a strong engine suitable for high boost
but when u add it all up and compare it to how much a good flowing cvh head costs on it own
and piston and rod packages seem to be the same for zetec or cvh
and at the end of the day you need to spend money on a cvh to acheive good relaiable power
the zvh was developed to allow people to benefit the stronger zetec bottom end and enable people to retain there standard inlet and exsaust etc but now aftermarket management is soo cheep full zetec is easier without fafing about
you only have to do the math to see which is best ive had all 3
cvh zvh and now zetec
dont get me wrong the zetec has its downsides aswell with the main 1 being the oil pump

I would say for strength at big power it makes sence to got for ZVH or Zetec. I am in a situation where to take my 1900 to well over 300bhp, is gona cost alot more then say a ZVH, plus the strength and reliablity of it cant be compared to a ZVH or full Zetec. I'v made my mind up, which is the 1900 aint strong enough for over 300hp coz of the old CVH design.
But dont get me wrong, if i wanted to keep it orginal, it would have a 1.6 cvh in it.

Cvh all day for me.i like taking the time and effort and money building a big power cvh.going the zetec route is all good if your lacking funds to build a monster cvh.just my opinion.love keeping it cvh.the amount of people who go to me,oh it aint a zvh or zetec is it,im like no,then you see them smile.everyone different.i like keeping it factory looking outside,big power cvh inside.im getting there slowly with mods.head alone cost 920quid,just head work.cvh costly.but so can any engine if your willing to do the work needed.

Believe me my friend, it aint an issue of being short of funds, the amount of money being invested into building a monster of a ZVH shows that. But if i was to pump the same dow into my cvh, yeah it probably will reach well over 300hp, but how strong will it be under extreme loads?? But for reliablity issues, and to protect the investment, i want a stronger design of engine.

You got wrong end of the stick.people want big power with min efforts.costs less to do than a cvh build.but as i also said,any engine can be built if you got the money.i didnt mean zetec are cheap,only when you want a simple power gain over the cvh it cheaper.then of course if you willing to spend the dosh on zetec for mental power,it gona cost more than cvh

Yeah i hear what ya saying mate, and i aint a hater of the cvh, i mean i have had that 1900 in mine, well tuned up for a ages, and it is a good lump. Just how i am thinking, if your looking for monster power, is it not best to invest in a newer, better design engine, which is potentailly stronger and more reliable with coping with higher power outputs?
Just my thinking towards this discussion, end of the day anything is possible, anything can be achieved, so cvh, zvh or full blown zetec can reach any figure, with money, as mentioned.

Bottom line is a ZVH has all the problems of a CVH and NONE of the advantages of a Zetec!
It is NOT stronger than a CVH, nor is it more reliable and it costs as much to build a good one as it does a Zetec Turbo so whats the point?
IMO if your staying CVH it's for originality, just because you want to, or because you dont have the budget for anything other than a stock CVH..... otherwise go ZT.
I'm CVH but had I known how far I was going with my car from the start I would have built a ZT.
