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.

Charlie,

                    At this stage I have to start somewhere as my
technical knowledge of Turbos on a scale of 1-10 is probably about  -5. 
Have lived with turbos all m,y life and know how to try and prevent
failure as it always costs about $2500 just to get one exchanged.  Then
there was the time one pumped about 25 litres of oil into the exhaust
system -- impossible to get out.  So just drove with a new turbo and a
blue smoke screen behind me that attracted every fire engine in the
country.  It took years to get all the oil out!

So just looking at fitting a turbo to my renesis to overcome the density
altitude on hot days.  Plus an education will not go astray.

Offers???  Neil.
