Mike,
I've gotten a lot of responses, nothing negative overall -- just caution on who will fix it when things go wrong.
As for the cost, one person mentioned a cost of around $3,500 to do the conversion when all is said and done -- IF you do it yourself.  You can go to http://www.smallcar.com and see what a turnkey conversion will cost.
In addition to the engine conversion, you should seriously consider a big brake upgrade, all things that go should be able to stop.  I've see that Smallcar also has the rear disc break upgrade as well.  So, I think I'll be doing 15" wheels soon, then upgrade the brakes, then engage the engine conversion.

Like how expensive is the conversion?
