Can I still use this compressor wheel??

[Acrocha3]

I have a small 16g turbo with a bent fin (has a slice in it) but I was just curious if its be safe to run on my car?...I just rebuild everything and had a different wheel but it didn't fit so I'm just curious if this could still work for awhile? Let me know you're opinions/suggestions thanks

I would not run it for the simple reason, small 16g wheels are a dime a dozen, you can easily pick one up for cheap.

What was the other wheel that didnt fit? 14b and small 16g have a smaller exducer than the other MHI wheels, big16 evo 16g 18g 20g all have 68mm exducers

Alright sounds reasonable...I'm pretty sure it's a big 16g wheel, my friend gave it to me saying it was a small 16g but when I rebuilt the old the new wheel was too wide to sit in the "seat" of the center section....in the pic the left one is the bigger one that won't fit into the groove (bottom pic pointed at), idk what exactly that groves called but all I know is that it doesn't fit , I read on here that I could get that grovove machined to fit?? Is that true?

Ok so then I take it the bigger one is the 68mm exducer

Balance is key to a long running turbo. That will throw it off not to mention the weird unpredictable airflow that will come off of that. Might cause surge under let off but I'm not a turbo engineer... yet.

btw exducer is the outer diameter of the compressor wheel and inducer is the diameter of the point of the fin and the naming flips on the turbine side. I think you were saying the exducer didn't fit in the housing which would make sense if your friend gave you a big 16g trying to fit a small 16g housing. I would only recommend using housings that are made for your compressor wheel for turbo health along with a shaft balance (find a place that balances turbos shafts. Usually around $40 for your turbo to be ready for thousands of miles).

Considering how fast these things spin, and you already have it out...I would just get a fine replacement wheel.
