ArchetypeDatsun Posted June 25, 2013 Report Share Posted June 25, 2013 The turbo it's self is a T3/TO4E so T3 rebuild kit should work, if you wanna save time take it to a turbo rebuilt shop I would ask what the proper rebuild kit it needs If I have time this week I can go to a turbo shop close to my work and ask they rebuild nothing but turbos. These turbos are a little rare to find. If you were to find a turbo of that size of today's turbos it would run you probably close to $800-$1000 give it a try if all fails then find a stock zxt T3 turbo. Quote Link to comment
DISLEXICDIME Posted June 25, 2013 Report Share Posted June 25, 2013 there is a shop on scappoose that rebuilds turbos you could go talk to them . i cant remember the name Quote Link to comment

I don't want to put another member into a bind on my behalf either :) there is a shop on scappoose that rebuilds turbos you could go talk to them . i cant remember the name Thankyou DISLEXIC ! That seems like a sensible solution as well. I just barely looked that up and emailed him this early AM ( I believe ? ). He replied back = " my base rate is typically $400 " I do need to just bring it in and talk to them like you said. Quote Link to comment

(2) journal bearings on the shaft (gold looking) .... just to the left of the compressor wheel is the "dynamic seal" that locks in the the thrust bearing.

Their words not mine :) lol .Turbo Cleaning 11 13 13 turbine shaft pics 001 by 71240z, on FlickrI'm looking at using a "staggered/step-gap" turbine side compressor seal since it looks like a superior design as opposed to a "butt-joint" .

I'm BLUE Posted November 23, 2013 Author Report Share Posted November 23, 2013 Turbine shaft seal (bigger one) , and compressor side seal (standard butt joint "piston ring" type) I'll be using the updated compressor seal in replacement of this one pictured during the rebuild.Journal bearings... they are held in by snap rings.270-degree bronze Thrust bearing (funny looking gold thing) , turbine housing bolts , backing plate bolts , brackets , locking brackets , exhaust studs(black) , snap rings , and that's pretty close to it ....

darrel Posted November 27, 2013 Report Share Posted November 27, 2013 When you were taking out the bolts, did you hit the heads with a chisel first? I was told it would break the hold the housing had on the bolts. 1 Quote Link to comment
