Hi
Andrew, I know next to nothing about turbo technology so
have stayed clear of them; IIRC this is the first time
I’ve heard of using a turbo from the agricultural industry
and advice to stay clear of the automotive type ... seems
to make sense – tractors use turbos that last for decades.

Into search of flyrotary archives, you’ll get about 30
posts from 2002 to 13 that are worth reading, other
searches will give more.
Basically you want something the size
of a T04 60-1, keep the A/R >1, something like 1.15 or
1.30
T04’s are plentiful from all the older
diesels like 2wd tractors from last century. you probably
got a few parked up around you that will still be
servicable. If you can find one without a intercooler on
it, chances are that it might have the right compressor.
Otherwise they are easy to change.
Steer clear of automotive turbo’s, they
will overspeed at altitude & disintegrate, need waste
gates & blow off valves. Stuff thats not required on
an aeroplane.
When installing. Put a normally open
solonoid valve in the oil supply line. Allows you to close
the oil supply if the turbo blows its seal.
Always bugged me why turbo shops charge
so much for such a simple part.
