Indirect injection does not lend itself to be turbocharged effectively. A cursory check will reveal that all of the high output turbocharged diesel engine are direct injected.
There weren't any real problems with this; more like challenges to be overcome. Things like a mechanical speedo drive going into an electronic speedo vehicle, arranging a marriage between a Datsun transmission yoke and a Ford drive shaft, doing away with the start/run/stop servo and replacing it with a cable system that would still allow enrichment on demand, building motor mounts from scratch. It was all good in the end and it never had to come back into the shop for changes....
dude, i drive an IDI VW diesel daily. n/a long block, with a turbo fitted.
and lots of IDIs came factory with a turbo.. look at the old 7.3 TD fords..
and the fact that lots of IDI VW diesels got turbos also..
IDI has nothing to do with how hard it is to turbo one of these SD22 engines..
the throttle body is the hardest work around when you are messing with these old engines.
ill say it again..
IDI does not hinder an engines ability to be turbo charged.. theres lots of turbo SD22s around..
my VW: 24:1 compression (more than a SD motor)
15 psi boost
cranked up fuel pump (governor mod so it will turn 6k RPMs, and cranked up the fuel screw till the revs almost hang)
so, i see no reason why you cant turbo a SD engine.. its just gonna be a bit more work..
