gt2554r rebuild
I bought a used gt2554r from here awhile back, and it has quite a bit more shaft play than advertised, so I want to rebuild it before I put it on my car. The compressor wheel moves up and down/side to side/in and out, and about any way imaginable, not a lot, but it does move in directions I dont think its supposed to.
Where do I get a rebuild kit, I've been looking but I don't understand what I need. I've heard they can't be rebuilt and need a whole chra, which I understand is everything but the housing as a unit? Are there any upgrades I could do with the compressor?
I would rather not get/use eBay parts.

Just run it, It's going to last a lot longer than you think. Its normal for ball beraing turbos to devop play, as long as it spins smoothly and is not touching the housing you will be fine. I have a gt2554 in my mazdaspeed protege that has had excessive play for 30,000+ miles and still works perfectly.

I'm wondering if it's possible to swap out the ball bearing chra with a journal one from a sr20 unit. I have a spare journal bearing chra that would cost $80 to rebuild. If you can remove the turbine wheel / shaft from the chra...measure it...length and diameter. I'll tell you if it's the same, and I'll sell you my chra cheap.
I have the wheel and shaft, but it's like .8mm different from sr20 to 2554. Something like that.

I'm not opposed to tearing into it, but I don't know the difference between journal bearing and a chra's ball bearing. If this doesn't pan out ill have to wait until next year to get a new turbo, no chance I'm gonna be able to come up with 7-900$ for a scavenge pump wheel...supposed to get married this year.
