E16g wheel slightly hit housing, salvagable?

[Throwback23]

My e16g developed some shaftplay pretty quick, the collars didnt want to comes off the shaft ect... But im tryimg to figure out what I can salvage.

Not sure if you can see but the wheel gave the housing a rubdown towards the bottom...will those affect flow if I use this wheel on a 14b?

1) That's not an Evo III compressor wheel- it's either a Small 16G or Big 16G depending on specs. I can tell by the blade shape and hub size.

2) You can't use any 16G wheel on a 14B.

3) Your turbine shaft looks junk based on the condition of the threads, and judging by the mushroom shape to the shaft tip on the compressor side it looks like you were beating on it to get the turbo apart which basically guarantees the shaft is bent.

Nice , the member that sold it to me claimed it was out of his evo 3 ...figures. My buddies dad rebuilds turbos and i had him it appart, supposedly the threads and shaft were as shown but regaurdless I figured it was junk. As for the using the 14b I thought I could use the 16g wheel, and housings on it but apperantly I have some more reading to do.

He rebuilds turbos but doesn't own a press to get stubborn shafts out, so he resorts to beating them out? Scary.

Lol, different strokes for different folks...on a serious note supposedly it was like that but I dont care much since the 14b has a good one I can use. Does that compressor wheel look usible though?

Minor contact- I'd clean it up a little with some 600-grit paper and definitely get the rotating assembly rebalanced once you get the rest of the parts and the center housing machined to accept the Big 16G wheel if you want the turbo to last. Who knows just how much material has been removed from the wheel from contacting the cover, or if it was removed unevenly.

So ive got one more question, it seems like its just going to be better if I buy another e16g and start over. I would like to know what is considered a bad center section. A guys I got to school with tried to tell me mine was bad because it looked as if the bearing had spun in the bore lightly scaring the center section. Im not sure if this is a true concern since it rides on oil but if I can use my center I might just go that route.

The bearings spin in the bore at half the speed of the shaft- that's what they do. Don't listen to people at your school that have absolutely no idea what they're talking about.


A bad center housing would consist of journals that are worn beyond the allowable oil tolerance, journals that are damaged from oil contamination, or damage the turbine sealing ring lip. If your journals were scored, you're suffering from oil contamination that is only going to ruin the next turbo you install.

Well shoot thanks for your time and help, its much appreciated...Heres a couple pics of the center section in question, the radial play was absolutely minimal I pulled it.

Herse the housing, would this affect flow if I were to use it?

Pfft- that's nothing. Now if it were this bad, I'd say you may have something to be concerned about:

Sweet, looks like ill be using the center and housings. Looks like ill be buying a shaft and compressor wheel soon. Thanks for the help!
