Ball bearings

[race_me89]

So I was talking to a fellow mechanic at work about turbos and he was try to tell me that some companys use steel ballbearings and some use ceramiac, his reason for diffrent types was because "ceramiac will wear down faster" ...?

I have been learning and reading everything I can about turbos and dsm's and galant's in general but I kind of was under the impression that all ball bearing turbos were ceramiac?

I didnt mean to be a noob I just wanted to hear some feed back on the subject

I am sure some companies use steel and some use ceremic. Iv know ceremic to be the better of the 2. I have a precision bb 50 trim on my galant and I love it. Fast spool up

It's one way or the other, both ballbearings are almost bulletproof. As long as it is installed the right way meaning the coolant cooling system is hooked up right, and you have oil restrictor and filters for oil feeds, and you check and clean the oil filter all the time. The both turbos are gonna last twice or 3times longer that any wetfloat bearings out there.

Ok thats good to know when my co worker said that I kinnda was stumped I thought water cooled ball bearings were simply the best option when he said steel ball bearings I intantly thought of heat cycles and expanding metal I feel that ceramic is the way 2 go
