The thread of the guy (Randy, from BC) who put an Isuzu diesel is here:

It's here on the diesel forum. The engine he used was a 4JB1-TC, which is a little different creature than your C223. The C223 and C223T were Trooper option engines from the mid/late 80s. If my memory serves, the only difference between the two is the turbocharging portions, but the displacement and basic design are the same. It might be very possible to scrounge the parts you'd need to turbo your existing beast. Hopefully Curtis Johnson, AirTrooper, or Jerry Lemond might chime in on this in the near future. Excellent application of a lesser known power plant. I'm sure many would be interested in the fitment and adaptation you had to do to make it work.

Welcome!
