Any time you open up a turbo CHRA, you should get the turbo re-balanced.

Remember to use proper spelling, punctuation, and grammar in your future posts, please.

There is no proof that the turbo should be rebalanced every time it's disassembled. The only time I would rebalance a turbine or compressor is if some modification was done (clipping, custom compressor mods) or if the wheel is slightly damaged and you don't want to replace it. The theory is that all turbine shaft and compressor wheel are balanced individually when new, so they should be able to be reassembled and will retain their perfect balance no matter what position the compressor wheel is on the turbine shaft.

I've heard from many turbo builders that new Mitsu turbos come only with balanced components- the CHRA is NOT balanced as a rotating assembly. If this is the case, there sure are alot of 14B's out there with 150K+ on them that prove this method works very well.

only problem I have is the compressor wheel hit the housing and wore away some of the wheel

Then I guess that wheel isn't balanced anymore, is it?

I would think it isn,t balanced anymore ,but I am putting it back on what have I got to loose ,i haven,t had much luck with any turbo,s I have put on this car. I bought a turbonetics 60-1 but when I got it ,to big for my setup ,now it sits in the closet .I might just sell it and get a gt 2871r .

Why don't you resell the 60-1? That's a popular turbo and someone would love to have it.
