Turbo for 7020

so last sunday I was planting alfalfa and it was pretty dusty and the then the tractor started chattering pretty badly and I found that the hose clamp holding the intake hose on the turbo snapped in half and the hose popped off and was sucking dirt pretty badly. I had only been planting for about 45 mins. my question is what new turbo would be the best for it? I am hoping to avoid cheap chinese garbage, is there a "mordern" upgrade that works well or should I be looking for a reman garett? Thanks 

If it was the 3" hose, I would be more concerned about engine than turbo. Turbo will stand more dirt than engine.            MACK

Stick with what it has.  It's an efficient engine and already pushing out 150hp (at the flywheel) from 301 cu inches.  That's pretty good for a tractor engine, especially of that era.  I would spend your money on buying a quality unit designed for it.  A bad turbo can take out an entire engine.  Check with your local diesel shops, they can usually get you a factory reman from AirResearch/Garrett turbo for a reasonable price.  I had to do that on my 7000 10 or so years back when a tree limb caught the muffler and broke the exhaust housing on the turbo.
