What do I look for when buying a Used turbo?

 

Nothing. Don't buy a used turbo. But if you must buy used then check for shaft play.

 

which used turbo?

(please OH gawd don't let him say Greddy...)

greddy kicks *** once it's rebuilt and upgraded properly

 

I dont think you can determine shaft play just by feeling it. If it moves so much that you can feel it, it is REALLY gone. (Mine did when I pulled it.) But, it could be out of spec and you might not be able to tell with your fingers.

But to answer the OP, you should look for a turbo that fits your application, in flow characteristics, flange fittings, lubrication, cooling and clearance. I think that covers all the bases?

 

Buying a used greddy turbo is a great option - the worse shape it is in/cheaper you can get it . the better . Then get it upgraded and rebuilt by BNR and you have got something way better and cheaper than if you had bought a new greddy ...... IMO

 

Listen to Brettus, he knows what he is talking about here! I would buy a junked GReddy turbo and send that off to Bryan@BNR asap. Inexpensive and great option by all reports.

 

I agree with finding the searchfunction!

 

 

That's not bearing play, that is a self-centering axel. That's a feature!

 

Interestingly , the 2nd hand turbo i got had about that amount of play so I got it rebuilt before fitting it . When I tried it again after the rebuild there was bugger all difference .
Since then it has done about 12000 miles with no issues .

 

yeah I have had rebuilds that have lasted just as long as new Greddy Turbos.

 

buy my kit, that is all.

 

^what kit ru selling?

 

A mitsubishi TD05/6 has around .035" up and down movement and .015" in and out movement. With oil in the turbo, you shouldn't feel any in and out (thrust) movement. Up and down you should feel a little bit, but the rotating assembly shouldn't touch the end housings as you are pushing and pulling on it by hand.

A typical garrett has .030" which is a little tighter than the Mitsubishi or Toyota turbos which are a little less tight.

The thing about the greddy units is the CHRA being non water cooled. This causes rear journal bearing coaking which can't be seen unless you take the turbocharger apart. When it coaks up so much, the car will start smoking after 30-45 seconds after you crank the car.
