My friend brought over this turbo and asked me to install it in his car. We were about to start when i took a closer look at it and noticed the fins. My friend bought the turbo used and the buyer told him it worked perfectly. It only has a few thousand miles on it and honestly looks brand new except for the fins. As far as i can tell theres no excessive shaft play side to side and no up and down. What do you guys think?

something went through there. he either got some dirt through it or something small the chipped them a little. I wouldn't install it. k03 sucks enough why would you want to sacrifice less airflow.

ps why do you think the guy sold such a new turbo. he knew he fucked up something and sold it off saying it worked fine just the fins are bad. fins don't just break because they want to.

hes gonna loose power if he installs that. those blades are pretty much the most important thing on the turbo. and make sure there is no shaft play.

I pulled off the compressor cover to take a better look at the compressor wheel and it has no other damage. Whatever it was that chewed up the fins had to be small. How hard would it be to replace the compressor wheel with one from another turbo?

The turbo has to be fully balanced seeing that it spins at 100,000 rpms. I would ask for my money back from the seller, but we all know he is just going to say the damage happend during shipping.

If you want to replace the compressor wheel, might as well have that turbo made into a hybrid k04. Should cost around $400. Link (http://www.gpopshop.com/rebuilding.html). Be sure to search on that shop's reputation though, as there are good and bad reviews on them.

i don't know if you'll see a power decrease, but the turbo will fail earlier since its not balanced. not worth it

I've run turbos that looked worse than that. It's not ideal, but it will work if you don't have another choice. On a turbo that small on stock software, you shouldn't notice anything.

It will spool up slower since it is now less efficient.

^Nowhere in that kit are the fan blades/compressor wheel listed as a part item. I think that kit is geared for shaft play, and would still need to be professionaly balanced.

If the balancing was ok it would work, but the balancing will have taken a hit sadly.

That looks like shit.

You can have it balanced for $20-$50 at a turbo shop, but it's going to make a lot of noise and be less efficient than an already lame K03 should be.

If he can't get his money back from the seller, find a blown K03 somewhere with a healthy compressor wheel and swap it over. Then you can have the new parts balanced together. In this case, you'll need to remove the turbine shaft/wheel and the flinger from the turbo, and have these "stacked parts" balanced as an assembly.
Balancing the CHRA as an assembly is not necessary as long as the rotating assembly has been balanced.
Reinstalling the flinger can be a total pain in the balls, as the piston ring seal that holds it in place usually does NOT want to go back in there.
