Are you talking about a 6610 S with a genesis engine and vertical oil filter?
If so... you're probably going to end up with cracked pistons.
I haven't done it... and personally I wouldn't. The main differences in those engines are that the turbo engine has a heavier piston with keystone rings and a larger wrist pin... the crank is nitrided to harden it. The valves have a different grind angle to cope with the extra heat. The engine will require an oil cooler and probably a larger fan depending on what's installed. There's also probably be differences in the balancer weights to deal with the heavier pistons... so there's a lot of little differences in those engines between turbo and N/A.
I suppose if you were going to turbo what you have and turn it up 10% or in the range of 85 PTO hp then you're probably not going to see a problem... but if you've got visions of cranking it out to 120 on the PTO you're going to break stuff. Genesis engines are well known to crack pistons if you set them too hot...
If you're dealing with an older 6610 with a square 268 engine... you probably won't get any more snort from it without an injector change to start with. That one will probably live for a while at 100 hp provided you monitor exhaust temps and keep it under 1000 or so. I expect it will eventually wear it's rings down along with the piston skirts and wrist pins. In that generation of engine the wrist pins were splash lubed on the N/A models and pressure lubed on the turbo models and that also added to the cooling of the piston... so if you get too much fuel into it you might just melt a piston down...
The compression ratio is also LOWER on the turbo engine of that generation... so that might lead to some piston cracking if you get too hot on a N/A piston.
