Without a doubt. However over 300bhp IMO will be hard to get out of a ZVH. Every big power ZVH Ive seen (turboboss, ian howell) have used Siemens injectors IIRC. I'm guessing the superior spray pattern must help get the most out of the engine.

I've got a ZVH engine because I bought a ZVH engine already made. But if Im honest, if I was building from scratch I'd go full Zetec.
