I received an evo 9 turbo with damaged exhaust side blades. Is the actual evo 9 and evo 8 cartridge the same, or is the compressor wheel and housing whats different? Can I separate the compressor wheel off the cartridge? Or can I simply use the exhaust wheel off my evo 8 turbo, and if so, how do you remove it?

Need help and advise asap. thanx

 

Unless you have taking turbos apart before, I would not do this. My suggestion is to send to Blouch Turbo. They can clean ur turbo and put in new blades or even better put in TME blades for faster spool-up.

 

even if it is the same, and you can swap parts (prob not) you will still need to have it balanced.

 

they are he same. mark the orientation of the blades on the 8 before you take it apart. use all the parts from the 8 and no rebalance will be needed.

 

I just took it apart today, lol. it is soo simple....
it is 2 snap rings and you have to pop a plate out.

excellent suggestions, thank you!

 

so looking at the pic below

part number 6 for the evo9 is the same as the evo8, even when part number 7 in the evo9 is larger than the evo8??

 

You will laugh at me when i tell you this but take it to a trackor place like john deer or something. Those places fix turbos all the time and i am sure there is a place like that local.

 

elhalisf,


I am not trying to discourage you or quention your skills to work on a turbo but in my best personal opinion I would absolutely will stay away from rebuilding your own turbo.

The turbos are machine balanced on a bench and they spin 140000-180000 revolutions. To your eye it might look balanced but in real load is can desintegrate in 100 pieces.

Now days is not worth trying to repair turbos on your garage. It is paramount that you send your turbo to a shop to swap parts.

I owned 13 turbo cars and I have had many other aftermarket turbos combos in all the cars. As of today I strongly believe a turbo should be left alone to the professionals. You can't cut corners trying to repair your own turbo. My .2c

best of luck though. Please PM me if you want recommendations on where to repair your turbo.

This is nothing difficult about rebuilding a turbo. People have been doing it without rebalancing forever!! I, along with many of my friends, have rebuilt Garrett based and Mitsubishi turbos with great success. The key is to make sure you clean everything properly, order the correct replacement parts and make correct measurememts when replacing the bearings/bushings.

If you are merely swapping cartidges a rebalance is not needed. That's like saying you need to rebalance all of the iternals of an engine when you replace a broken engine with a known-good engine.

If you are not confident with your abilities to repair a turbo it is best to leave the repair up to someone who doesn't have any doubts about the repair.

 

I've seen a couple turbos snap the shaft in half from not being balanced and being ran for 15k-20k miles.

 

I have seen brand new turbos fail so what's your point?

 

yeah I can imagine what would happan if you dont balance it........... BOOM!

 

If he is only changing the chra, a rebalance is not needed. A blind paraplegic monkey with one broken arm can change a CHRA without screwing it up

 

Let us know if all those spinning parts are the same between the 8 and 9.

 

yep, its the same.
i did the swap, and it was successful. the CHRA is not the same, but the internals and blades are the same.
