Yes, I got an IC from a single turbo RX7 in hopes of
using it on a small engine turbo project.  They have this 
12x9x3 air/air intercooler that sits on top of the engine
and seals against the hood..  Anyway, the inside of it
was really ugly, so I went back to look at the engine it 
came from, and there was a water injection "jet" plumbed
into the the turbo-to-IC pipe..   The guys who yanked the
engine over in Japan, and shipped it to Dave had simply 
snipped the water tube close to the jet, so it was hardly
 noticable.
