EVO III 16g rebuild options

[DSMDEMON93]

Hey guys, so I received a real deal evo 3, that blew smoke, but spooled. I have purchased a decent rebuild kit, and ripped it apart to rebuild the turbo. I have rebuilt my fair share of mhi turbos, but this one has me stumped. In the journals, I notice very VERY small scratches in the journal surface, from possible oil contamination, from the previous rebuild I noticed the previous owner has done.

My question is: Would dropping in the std. size bearing kit be sufficient for the rebuild? Or would I need to run through a machinist to remove some material, and order an oversize bearing kit? Any input will be appreciated.

HERE IS A PHOTO: (Note: The surface rust is from sitting, it has been oiled prior to storage, but I don't know why it still built up as fast.

I would send jusmx a pm and the picture he could easily let you know in a hurry.

hone out .005 over and order bearings, look around for them if no one else has them shoot me a pm for custom bearings, however I perfer only to sell bearings to other turbo builders as I doubt you would need a 10 pack

I would also goff your bearing housing

Those scratches don't look very serious to me at all. I'd be more concerned with the actual fitment and oil tolerance of the bearing itself.

those scratches arn't anything to worry about, polish them out by hand with some 600grit or so, measure the diameter, that's what matters when it coms to ordering other bearing sizes, don't just start hopping on .005 undersize/oversize bearings or you'l end up with a pile of parts that just quite won't all push tgther

trust me, or get more info from jusMx, there's a good bit of difference in the first step of bearing sizing away from OEM and you'll b well within spec polishin out those marks as long as the CHRA sizes are currentlywithin spec.

I"m rebuilding a 16g right now that was oil starved for only a few minutes (rig welded it's self to turbine, specs of metal welded inside CHRA and more) i'm not saying this is a typical rebuild (far from it) but I bet this turbo comes out usable (will probably have issiues with the turbine end oil ring) but the customer has no funds to buy another or replace boththe turbine and CHRA so i'm machinng, polishin and working magic on the parts that are there to make it a whole working turbo again and already from what i've done on the lathe and by hand i'm STILL withinstock bearing clearncs..wish i had some pics to toss up, but thn again people might make fun of me for even attempting the repair, but i bet it works, boosts just fine and makes it's power to it's fll potential

Pm Myself or justin if you need more info you don't get answere here, i'm alwayus glad to help, and like i said,mm you should be fine if tolorances are in spec currently and you're just cleaning up whats in that pic with some fine paper and some manual labor (no power tools unless you're well exerienced)

Hey glenn how were the bearings I sent you working out good? If you need any help machining your.cart, let me know I may have .10 over rings for the seal. Anything you need let me know, you do good business.
