Have you actually priced up the difference between a zvh and full zetec? You have to do more cocking around to get the zvh built, which means more labour.. The standard zetec head and cams package will flow 320bhp all day long (with a T34).. A bog standard 2 litre zetec with a set of pistons, injectors and a T3 will piss 250bhp all day, every day, for a long time.. lag? what lag?

Let me price it for you..

Donor Engine = £100
Machine everything = £300 (bore&hone/line-hone mains)
AE C20LET Pistons = £300
Uprated Valve Springs = £100
Gaskets, bearings, pumps and blah = £300
= £1100 in parts plus half a day to bolt it together (this assumes no headwork or head rebuild, rebuild head = £250-300)..

No doubt i've not accounted for absolutely everything, but it's 95% complete including all big spend items..


Then spend as much money as you want on management, turbos, intercoolers, injectors, map sensors, looms, blah blah blah.. all this stuff is much the same whether you do it on a zvh or zetec..


Now price up a zvh, including adapters, modifying this that, blah blah and tell me it's a lot cheaper, if at all! Probably quite the opposite!
