The reason I didn't mention the price, is because I didn't want to explain it all, but if you insist :-)

 

I paid $400 for the single, and when he shipped it, he also threw in the smallest turbo I've ever seen.  I'm thinking of putting that baby on my lawn mower, or maybe a radio controlled plane.  It's only 5.5 lbs, and has a 1" diameter exhaust inlet.  It was actually used on an original Wankel engine, so I guess it's historical :-)

 

For an engine that was ready to run, I'd expect to pay way more than $400, but we both knew this wasn't ready to run.  It was something he personally purchased for use on a jet ski, and wasn't part of his research work.   It was well worth $400 to me, so nobody got screwed :-) 

 

Hope everyone's happy now :-)

 

Cheers,

Rusty
