Neil, Type    Turbo selection     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.
