Alright, I found a garrett 60 trim turbo, .63 a/r, t3/t4 locally that needs a rebuild for $100. the owner says it went bad when the oil pump in his car died and fried the bearings inside the turbo.

i did a quick search on froogle and found this page below:

http://www.gpopshop.com/garrettt3kits.html

do the kits on this page look like they might be the right thing? if they are, then this "shouldn't" be too bad of a deal. i just figured bearings alone that can handle 100k+rpm would be the price of those kits themselves :P

the guy has told me there is a small chip in one of the fins on the exhaust side. i haven't found a solid source for a replacement turbine.

what do they cost? i found some for some turbonetics turbos/etc and they're ~$100 or so.

how easy/reliable is a home-rebuilt turbo? that's the one thing that i'm worried about.

you can find them on ebay and if i'm not mistaken there is a seller that sells you the rebuild kit, you rebuild it and send him the shaft/fins and he'll balance it for you

got mine for free a t3 t4 turbo cause the guy didn't know you can rebuild it. got me an ebay rebuild kit and so far its running good

i read this here:

http://reviews.ebay.com/The-qu...67810

and have become afraid of the ebay kits...

i'm sure there's a machine shop around here (or like a big truck repair shop) that can balance it for me. i went ahead and paid the guy for it, it should be shipping out today.

still nothing?

i have found a good source for the rebuild kits, but nothing for the replacement wheels...

can someone please help?

hey airman,

I used to work at Garrett (Honeywell, actually - Garrett is now just the racing/motorsports division) and I can tell you it's worth it to pay good money to have your turbine wheel properly balanced. You may get a good one from ebay, but be careful. If the assembly isn't balanced properly your bearings will go out fast. Other very real possibilities is catastrophic failure of your wheel, which, depending which wheel, can screw up your motor too by sending tiny metal particles up your intake pipe : P

Talk to Garrett or licensed Garrett dealers - i'm sure they get questions like yours all the time.

I'm trying to scare you a little bit to get the point across NOT to cheap out on turbos. It could cost you wayyy more down the road.

i wouldn't touch an ebay rebuild kit with a 20 foot pole. you couldn't come up to me and say hey, here's $100 and an ebay rebuild kit, just put it on. plus, i wouldn't do it without balancing the thing either. it will definitely be balanced after i'm done assembling it. i found a local place that works on big turbo diesels and they said they'd balance it for me for $60 or so.

anyways, gpopshop looks like where i'm going to be able to get everything. they have the compressor wheels and turbine shafts, too. I didn't realize how bad of shape the turbine shaft was in, it's going to need a new one for sure.

the turbine shaft is $195 from gpopshop. my compressor wheel is in questionable shape, here's a picture.



the edges are a little...i guess i'll say dull, with a few tiny chips. i don't want to cheap out, but i don't want to spend money that's unnecessary. if it's needed, i'd buy it for sure. also, is there a point to getting the replacement clamps?

more than a "little" dull! I'd replace that compressor wheel. I bet if you look inside the compressor housing, you'll see witness marks of the wheel rubbing on the housing (since you can clearly see from the edge of the compressor blade it's been rubbing). The good news - more than likely you can re-use the compressor housing.

The damage to the leading edge of the compressor wheel fins could affect its performance, so besides the peace of mind your compressor wheel won't experience some weird behavior during use (since the chips and rubbing changed the mechanical structure of the fins), you may get better efficiency (more power!)

I would replace the clamps (i know they're expensive for what they are). But you could avoid some sealing issues..(i'm assuming you're talking about the t-clamps that hold your compressor / turbine housing clock position)

according to gpopshop, the clamps are only a few dollars a piece so I might as well buy the whole rebuild kit for $90.

really my ONLY concern for this turbo is the compressor back plate. (i'm going to use the terminology found on this page to describe this: http://www.gpopshop.com/garrettt3kits.html )



it's obvious where my concern is (in case it really isn't, right in the center where the thrust collar lines up). trying to figure out oil passages/etc and where oil will be, i can't figure out how this part seals oil from escaping. As you can see, the surface is a little disturbed. Will this have to be machine/replaced to a smooth finish? the turbo did not have any side to side play on it before i pulled it apart (as in the direction the shaft points).

I guess i'll have to order the kit and see what all is there.

so far i'm thinking...$100 for bad turbo that needs a new turbine AND a compressor wheel ontop of a rebuild. from gpopshop, the only place i can find that sells genuine parts, that's $195 for turbine and shaft, $90 for compressor wheel, and another $90 for the rebuild kit. the compressor back plate needs to be replaced, my caliper read the opening at 0.510 and the tolerance is 4.996 to 5.001, i'm not sure what happened to cause the damage in the picture above, but oh well.

a new back plate is $50. so - that's $535 after the cost of the turbo, then i have to get it balanced....let's guess $600 in total.

i can't find anywhere selling the exact thing, garrett model #466159-5004 so I can't get an idea on what these things are priced new.

i calculated it to be a 56 trim, with a .63 exhaust and .60 intake (or the other way around). will i still come out under the cost of a new turbo or should i just go that route?

if you see tiny holes, that's probably where the oil travels. I'm not exactly sure how the dynamic bearing works either, but from what I understand, when it spins it creates a pressure difference across the inside and outside of the bearing. The holes that are situated radially kinda "sucks" the oil from along the shaft and "flings" it outward and away from the compressor volume. I *think* it's how it works, but don't quote me on that : P

About the backplate, it'd be a good idea to replace that as well. I'm not sure if machining would be a good idea since it already looks like it's outside of the originally specified tolerance band (and the tolerances on these CHRA's are really, really tight!

Not sure about retail on this guy. I know a GT28rs cost ~1500 new. When I worked there i got em new for 800 haha!

well, this isn't a ball bearing one. i'm pretty sure retail is 700-800 so i guess i'm still coming out on top, but i was gonna try to save money this way haha. learned my lesson there :P
