What exactly does it take to convert an engine to non-turbo? Do
higher compression pistons need to be installed? What of the
injection system? Anyone out there a powerplant mechanic who knows
his way around this issue???

First, I'm not a mechanic, but having a IO540 that was turboed at one
time...it will take a new set of high compression pistons along with
rings and a hone job.

The injectors are different, but "as_I_recall" you could use the
injectors from the turbo. They are pressurized when used with the
turbo.

There's bound to be some one on here who knows the details.
