turbo question?

Just have to say Love my fords and love the site. So here is the scoop truck is a 1999 f250 7.3l 130,000 miles I purchased the truck with 112,000 today I decided to replace my crappy rusty looking differential cover and replace the fluid in the rear and front all went well with that. Decided to check my air filter fluids ect as I do once a week. (I am like clockwork with following oil and filter replacements ect.) decided to look down the intake tube with a flashlight just to check some things out while it was off. Came to find out my turbo compressor wheel has no dirty look to it but corners are worn off not horrible but about 3mm off the outside corners. So to the real question I was looking into turbo rebuild kits for about 130 bucks but none of them include the exhaust side turbine should I just replace everything but that and use the old exhaust turbine or will that cause a balance issue? Truck runs flawless everyday no problems or noises no smoke at all. and i'm trying not to worry myself with the whole dusted thing it doesnt look like a sand blaster hit it and I don't have any blow by so i'm trying to make myself fell better about it. call me crazy but my thought is that this thing is supposed to be balanced perfect if its ok to rebuild the whole thing and reuse the old exhaust wheel I will do it and any input into quality kits would be appreciated thanks in advance for the help.

I am not sure about rebuilding turbos, but sounds like you need to upgrade your air intake.

Can you post a pic of the intake impeller, im just curious to see how bad it is.

Sometimes with bad surging over time the wheel will get screwed up even if the air is filtered properly.

Even though you're "supposed to" re balance everything, every DIY guy out there that has re built his turbo in the garage has done so with the standard kit and no re balance.
99% of those have had no issue.
The new (hopefully billet) wheel you're going to install has already been balanced on its own, as has the rest of your turbo assembly.
I say to for it.

Thanks I will try and get a picture up as soon as I can I guess I will just rebuild the whole thing while I'm at it as a piece of mind . Just worried about it being worn I will be upgrading my intake to the DIY 6637 filter very soon.

As I understand it the turbine wheels, and the compressor wheels are milled/machined to each be a neutral balance.
That way it does not matter what aftermarket compressor wheel you get - there should be no imbalance.
Now, unless there are chunks missing out of the turbine wheel causing imbalance or, if a bearing failure has eroded the shaft - yes, you will want to get a new one.
