Hi,

I'm doing a little bit of research at the moment. We have a fairly low key, subtle car over here called the Rover 623, which has the H23A engine. I just bought one and I'm looking into what can be done with it. Obviously I've heard of the H22 conversion, but I want to know what I can do with the existing engine before I consider going down that route!

I've done some searching, here and on other forums, but I'm not too clear about whether or not performance cams exist for this engine. Can anyone shed any light on this?

Looking forward to learning lots.
