im thinking about sourcing a 2ltr zetec block and goin about a zvh conversion cuz i cant afford a 1.9 tall block.............thing is ive heard zvh engines just break all the time and are mega unreliable and there not very oil tight. is this true???? cuz i was thinking more on the lines of....if it was built properly it would be ok???

 

mines a 2.0l zvh ive just bought th car and the engine is fairly new only time will tell if the engine is reliable, i hope so

 

keep it CVH mate

 

you have been hearing total crap zvh is very reliable, more reliable then a cvh so their you go

 

Definately agree with SufsRS mate, a well built ZVH conversion is both well worth it and reliable IMO...

Lots of people on this site have them alone and persoanlly i'd probably go with one of these over the CVH, you get much better torque from the Zetec Bottom End to start with

To be honest aswell, i'd say they were probably easier to tune aswell!

Why dont you ring a couple of tuners and see what response you get, dont listen tom pub talk mate, never worth it! HTH

 

aint got NO reliability problems with my 1800 cvh,produces loads of torque too!!

 

im not saying all cvh's are shit but the ZVH produces more reliable power then a tuned cvh

 

we'll have to agree to disagree on this one
funny that all the escort's that broke the 160 mph mark and produced the most power in this months daddy thrash are all cvh driven though

 

yep otherwise we will be going on forever

 

ive herd zvh run very hot? (could be bollocks) ive also herd that the low end tourque makes them gear box breaking tourque steering monsters to drive?

 

zvh it is then me thinks!

 

What you have heard about the zvh is a load of bollocks

excellant bit of kit

 

i ve got a zvh!

had a few probs but that was due to mapping issues!

they are very strong imo!

well i ve seen a zvh break the 400 bhp barrier at field motorsport

and it had the same amount of torque!

im aimin for 350 bhp and lbs of torque with mine!



i also know of some mega bhp cvh s that are near to 350 bhp!

and they are 1600 still!

 

davey it is quite amazing to see how much the cvh and zvh have progressed some silly power figures these days
