I did my research on this one looking at a Boston Bob rebuild, Tiico,
Subaru, and DIY approach.  My goal was to keep things as stock as possible,
have it serviceable anywhere (the van's a traveller), increase performance,
reliability and mileage.  I ended up doing a VW inline 4.  Although I'm
very happy with the results, how how I got there was neither cheap, nor
fun.  My story, including a tip or two on dealing with list vendors (or
anyone selling used parts) is here:

Alistar Bell's site is an excellent source of info/links on the I4 approach:

If you're looking for Subie and Tiico stuff try the yahoo groups:

If you're considering a rebuilt WBX, I'd seriously look at Boston Bob.
Although I didn't go this route, I did speak with him and have read many of
his posts.  He knows what he's talking about.

Hope this helps.
