Has anyone out there in Vanagon land put a TiiCo in an aircooled van?  If not, is there anyone that's done any type of aircooled to watercooled conversion?  Anyone put a Zetec in an aircooled van?

I love the simplicity of my aircooled motor, but I'm getting a bit tired of it's minimal power.  I've invested a lot into the body and interior of my van, and would rather not start all over with a new van.  Plus, it has sentimental value.

Anyone?

Cheers, 
Greg.
