One thing I've kind of been wondering about. What's the capability of the 505IJ I know some guys say they run them to 400 HP in the MX270's with just the different injectors, and, I'd think, a little time with the laptop. It would be interesting to talk to a pump shop_diesel shop. For the investment in a pump, lines, injectors, turboIJ you might be able to do what you want with the existing engine. Probably wouldn't meet emmissions though;0) Chads
