Thanks for all the insight/advice and parts listings for the 4200! My dad's been a mechanic (specializing in chevy and gm stuff) for over 25 yrs, but he's never really messed with any of the computer tuning, especially with a turbo! That's the main thing that is intimidating us a little bit...Do you know how thick the cylinder walls are on a stock 06-09 4200 block? Do you recommend sleeving the block for a turbo application? I know it'll add strength and at the very least durability and piece of mind for future yrs of use.
