Ok so ive got a question Sam.
http://www.vfaq.com/proj-pics/turbo/rebuild-23.jpg

I did not put that little brass thing between the turbine and the CHRA, did you? That picture is not from an sr20 turbo so im un sure if i forgot to put it in or if our turbo even uses that there. Thanks

That piece is the bearing. All Journal Bearing Garrett T25 CHRA's are 99% identially constructed. If you re-assembled your turbo without the gold bearing in the turbine side, you will **** oil into your exhaust housing for about 30 seconds and then the turbo will disintegrate internally. Hopefully you are still on the driveway when this happens.

Post#4 discusses the turbine side, and the bearing is mentioned and the first picture shows it installed.

When you disasembled your turbo, didn't you remove a bearing from either side?

I wouldn't be surprised if you find the shaft scored and the turbine blades have nicked the sides of the housing. At 100k+rpm, not having that bearing in means all the stress of keeping the shaft aligned rests on the front bearing... I can't believe it didn't grenade the thing the first time you got into boost.
