---- Copper 280zx turbo ----


I'm BLUE

Recommended Posts

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.

Thankyou I appreciate that Arche ! 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.

600hp? DTP you got a winner! These old school aftermarket parts are really neat. If you find an old school supercharger I call dibs! :P

 

No kidding huh :blink: ? :lol:

 

They are too neat...

 

hahah :lol: I'll keep ya in mind if I do Kirden ;)

I've been either occupied or unable to work on my stuff for a bit.

Nice to be able to now and again :)

I have the turbo separated off the manifold , but am away from my sanctuary , so will have to get pics another time.

Turbo will be re-built.

Turbo Dis-assembly.

Started with something close to this , but had already pulled the cotter key and actuator off. ( as well as some bolts ).

Compressor housing is on the <--- left (aluminum) ... turbine housing is on the right ----> .... CHRA is in the center of it all :)

Split it all apart ... there were 2 broken bolts in the turbine housing already , and I slightly rounded one bolt head .. that was in a hard to reach place (only could get an open ended wrench in there...) after about 5-10 minutes or more I popped it loose .. was happy :)

This is  part of the CHRA (less compressor wheel + thrust washer + retainer and compressor backing plate ? haha)

You can see the journal bearing in the center ( it is held in by a snap ring on each side to keep it in place.. oil floating :) ).

Remember you're looking at the compressor side (cool side).

Another view of the down-pipe.
On the right is where it literally hooks to the exhaust pipe (if you weren't famaliar :) )
On the left is where is connects to the turbo housing :D

This is the thrust bearing .. and the dynamic seal floats inside it (has another tiny "piston ring looking" compressor seal on it). Thrust bearing looks like a "butterfly" in my fingers :)
NOTE: --- this not the only sole bearing if you arn't aware already :)

At the top is the oil "feed" (with the white tape wrapped around) I choose to take out the banjo fitting instead of the 2 12mm bolts.
At the bottom is the oil "return" port.
You are looking at the compressor side ... facing yourself ... where the thrust bearing/retainer/compressor housing plate etc all assemble on.
In the center are a couple of snap rings holding the journal bearings.
There are (2) journal bearings on this model.

The journal bearing slid right out.

A closer look at the thrust bearing and dynamic seal.
NOTE: The thrust bearing locates on (2) roll pins in the housing , and it has oiling grooves that are to pointed inwards <--- when assemblying :)

Turbine side shield ? I'm not sure of the entire purpose at this moment , but will look later.
it goes on the turbine shaft over the seals it looks like.

All I can do for this very moment.

turbine side journal bearing and snap-ring.
Yeah I think it needs to be replaced :)

A closer look ... I know it's hard to see ... you're looking at seals that look like "small piston rings" ;)
The rear seal (towards the turbine) looked "ok" , but that's just me looking at it. Yeah not a good test lol.

You can see in this picture the "gold plated" looking rings around the bolts.
These rings are also split ... not one continous unit :)
Those keep everything clamped together(or from walking if you will to describe ?) as we all know.

I kept spinning the turbines/shaft while taking it apart carefully to make it wasn't contact much if at all.
minimal , but did a touch on the inside myself ... *roll eyes*

Been cleaning the turbo parts as I go along... I'm trying to get the stuff as clean as am reasonably able to.

You can see the (2) internal snap-rings that hold the (2) journal bearings in the housing. As soon as they are installed then (1) more snap ring on the outside of each journal bearing is fitted externally to hold them in place. Wear looks normal.

Still in the process of re-cleaning all of this stuff before using.

Cleaned the compressor housing. Paint is on there pretty good so either chemicals or bead blasting... or just leave it :)

I have no reason to pull this apart. Waste gate is very free and clean/clear. If need be I'll heat it up carefully and pull the bolts out. Penetration fluid first of course before doing so.

Other side of the compressor backing plate. It looks dirty , but it is nearly.. clean. A lot of that stuff is baked in or something.

Inside the center of the compressor backing plate is where the dynamic "piston ring seal" (it's the type) locks in and rides.
The wears looks normal and nothing alarming.
NOTE: it looks like there is a "chip" off the edge of the center , but it is casted in.. so not a chip :)

NOTE: I have not... cleaned anything on this shaft yet until I figure out what is safe to do so with. Will be looking tonight

Turbine wheel on the left ... compressor wheel on the right ... (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. This is considered to be a "hybrid turbo" by rebuilder's and parts suppliers from what I have been told/understand. Their words not mine :) lol .

I'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'll be doing more research before executing though.

From the left: Compressor side journal bearing ---> Thrust bearing ----> Dynamic seal ----> compressor wheel. Many of the T3/T4's-ish ... from what I understand use the 4-piece carbon seals as opposed to the Dynamic seal. I'm glad I pulled my turbo apart before ordered to be 100% sure.

That's great that you found a rebuild kit takes time things are coming along.

 

Thanks Arche ! yeah it does take time. I had to email , call , etc 5-6 places , and none of them had a clue which kit I needed.

 

So it's satisfying that at least it's moving along and might get done :lol: :D

Oil inlet/outlet gaskets. Compressor backing plate seal/o-ring (black). , and what looks to be a housing seal/o-ring ? I'm not sure will have to measure the size against mine.

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 .... I think haha.

Doing a "little" work.. ( lol just a little ).

Decided to start drilling out the broken bolt.
The other broken bolt I shall slip a nut over the top .. weld it onto the existing snapped bolt protruding surface and wrench the effer out.

Left hand drill bits ( and right hand drill bits..)
11060839105_a3e860e58f_c.jpg

3/32nd LHD drill bit seemed to be doing a fair job.

Explanation needed ? if drilling lots (or even a little) there should be lubricant involved :) .

a bit off center lol , but should be fine
11060942896_ef3980cedd_c.jpg

It's practically drilled through as this point , but no pictures.
Have to go pick up another bit or two since I was kinda stupidly tired  + snapped the bit  :shock:  :lol:

That's all for nowz ...
