Hi,
Not try trying to hose down your parade but....
My short answer is I don't know....never tried it....never heard of it being done.
But I do think that, if you do a bit of research, you'll find that it's not a simple delete operation with injector swap. I know the turbo engine is equipped with lower compression pistons for one thing. Check part numbers to verify.
There will also be a valve timing variance that hurts me to even think about.
If you do what you're thinking, I'm sure they will start and run...well...idle anyway. But you might be very disappointed with absolutely no power at all and gobs of black exhaust even with smaller injectors. I would liken it to a very inefficient cloud making machine that won't go anywhere slowly. .
If your base engines are solid I think your most cost effective route would actually be to refresh the turbos and intercoolers.
The only real maintenance with turbos is to always provide them with fresh, clean oil. If you don't keep up with that then, yes, you can expect trouble.
Remember, just because you have all that power doesn't mean you have to use it.
EXCEPT, of course, only when you're HAVING FUN ;>)
Just my opinion.
Good luck.
