Areet there hatch, well i had a 1.6 cvh with a few mods and was impressed for about 2 weeks until it blew up i have since built a 1.8 zvh and it runs 180 under the same mods where as the origianl 1.6 only run about 160 if it was lucky on a good day.

I'd say zvh all day long as they are a much nicer drive while delivering more bhp than the all or nothing high horse powered cvh's. but i'm biased as i can build them for nothing otherwise id probably go for a cvh for the same money if i had to pay.
