I have no idea, just bought the turbo. It doesn't seems to great for me i guess the hardest part now is going to find a replacement compressor wheel.What happend? No air filter ? Looks like a cold air intake pos pod filter was used.
The compressor wheel is 68/50mm, it would be nice to find something that won't need machining.I don't know what size your compressor wheel is, but there may be a newer style available with the same size profile. I do wonder where all the wear came from, and any decent turbo shop should be able to polish the comp wheel and rebalance it.
not even close, turbo shops are cheap for repairs, about $100 for the job to ballance. you can't just take material off and expect it to last.You can carefully grind a bit from the scrapes or just do nothing and put all together. Difference in efficiency or balancing is hardly measureable.
As I said, effect in balancing is hardly measureable, within tolerances. I'm not suggesting to take material off to smooth up those marks completely. Only if there are some small bits that may break away.not even close, turbo shops are cheap for repairs, about $100 for the job to ballance. you can't just take material off and expect it to last.
Different number of blades but this might help?
