It would appear that most of their evaporator cores run in the 200 to 350 dollar price range.  Hope this helps.  Paul Conner

 
A number of guys are using cores from large, late 80's American cars, such as the Chevy Caprice.  This should be somewhere in the ballpark of 13" x 9" x 3.5", though exact dimensions are illusive.  Anyway, such a core goes for about $120 at the local Advanced Auto Parts place. 
 
don't want to start
collecting radiators. I will leave that to Rusty.  Paul Conner
 
 
Very funny :-)  I'm still working on the rev-2 radiator, and haven't committed to any particular design yet.  I would like to use the cheap, and available evap cores, but they're just too thick for the space I have available, especially when you consider that I have a 2" thick oil cooler to add to the thickness.  I'll probably go with the smaller Howe radiator.  Still also contemplating 2 EWP's, vs. 1 ewp and the stock pump.  Gotta figure out what I have room for. 
 
FWIW, I spend yesterday removing all the items that need to come off for the rev-2 upgrade.  It's just amazing how small the engine is without all that crap in place.  The next step is to fit the new cowl, then start modifying stuff to fit inside. 
 
I found a bunch of new cracks in my turbo manifold, which was no surprise.  I also found that he turbo manifold burned off the paint on one of the mount tubes, even though it had a heat shield, and the tube was wrapped with fire sleeve.  The fire sleeve didn't appear damaged, but the paint below it was burned.  The most amazing thing was the heat insulation wrap that I had on my turbo outlet pipe.  This is the silver stuff, with the high temp fiberglass backing.  It's supposed to be good for 2000 degrees, and seemed to be holding up well, until I took it off.  The heat turned the fiberglass backing turned to glass- literally.  If I handed a piece to someone, let them feel it, look at it, and drop it to listen to the sound, they would have concluded that it was glass.  Very cool, but not in a useful sort of way :-)
