Rover k-series VVC head

[jitsukadave]

I've found out a little about this head unit, but I'm not sure how reliable they are, or how easy they are to work on. Anybody know?

Is this any help?

Cheers!

It seems the answer is not really:
The standard Lotus Elise series 2 111S (VVC engine) setup runs at 156bhp. With 1500 quid these guys can get one to run at 170(ish) by porting, timing, new exhaust cam, new throttle bodies, and doing a bit of work on the inlet and exhaust. Or they can just "block off" the VVC mechinism & replace the cams (e.g. bodge convertion to a standard head - though 'bodge' may be a bit harsh, I don't see why you wouldn't just swap the head for a standard unit in this case??).

Thanks again for the reply - at least I know what can be done now.

I believe the reason for using a VVC head rather than the normal one is that the ports and valves are bigger, among other differences. The blanking plate mod is quite a common thing, or you could buy a VHPD head if you can find one.
