BLUE's Copper ZXT

Postby BLUE » Wed Jun 26, 2013 7:42 pm

I bought This 81' 280zx turbo. (Thankyou Arche)

Yes yes I know... another z-car ... I have a problem ... [:rofl:]

I wasn't going to post anything until I was a bit further along with it , but thought I might get the ball rolling !

-Z31 300zx Turbo set up (ECU & MAF)
-AiResearch T3/TO4E Turbo
-Steeda Short Shifter (Aftermarket Mustang shifter)
-Stock exhaust with 3" Megan muffler
-Aluminum Koyo radiator dual electric fans
-MSA front & rear sway bars
-HID lights
-Aftermarket headlights
-Headlight covers
-JVC stereo w/ Pioneer Speakers
-16" Ultra Wheels
-New NGK spark plugs
-New Spark plug wires
-New Cap & Rotor

Pictures from a bit ago after being washed up.

------------------------------------Plans & Goals------------------------------------------------

-Get it fixed up and back up to daily driver status (I'll elaborate more on that as things progress)

-finish paint touch up if possible

-paint and hopefully mount a spare nice condition bumper.

-go through and fix any small things etc etc.

-plans go from there !

As far as the car itself goes... It's very apparent the previous owners loved the car inside and out.. (good job Arche) [:thumbup:]

It's pretty neat to have a short throw shifter on the T5 transmission itself , and definetly a "different" feeling when shifting on this transmission !

Anyways thanks for tuning in and I hope to have some more significant posts than just pictures of my car here soon [:rofl:]

Turbo Dis-assembly.

Started with something close to this , but had already pulled the cotter key and actuator off. ( as well as some bolts ).
Image
Copper Stuff 11 11 13 110 by 71240z, on Flickr
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 the CHRA (less compressor wheel + thrust bearing + dynamic seal 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
Image
Copper Stuff 11 11 13 093 by 71240z, on Flickr

This is the thrust bearing .. and the dynamic seal is located inside the thrustbearing (cylinder looking thing)
NOTE: --- this not the only sole bearing if you arn't aware already :)
Image
Copper Stuff 11 11 13 092 by 71240z, on Flickr

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/dynamic seal/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.
Image
Copper Stuff 11 11 13 090 by 71240z, on Flickr

After using snap-ring pliers to pull (1) snap-ring out of the compressor side.
The journal bearing slid right out.
Image
Copper Stuff 11 11 13 089 by 71240z, on Flickr

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

Copper Stuff 11 11 13 087 by 71240z, on Flickr

Another look at the housing.
Oil outlet is pictured.
Compressor side is facing ^^^ up.
Turbine side is facing down.
I'll be taking the oil flange bolts out when it's time for cleaning ...
Image
Copper Stuff 11 11 13 086 by 71240z, on Flickr

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.
Image
Copper Stuff 11 11 13 085 by 71240z, on Flickr

Turbine side journal bearing and snap-ring.
NOTE: journal bearings have oil holes drilled in them for lubrication 8-) (if you weren't already aware).

Opps forgot to mention ... I marked the assemblys and what not the best I could before dis-assembly.
All I can do for this very moment.

turbine side journal bearing and snap-ring.
Yeah I think it needs to be replaced :)
Image
Copper Stuff 11 11 13 084 by 71240z, on Flickr

The shaft.
Turbine wheel to the left.
The surfaces look pretty good really (although this is my first turbo ... lol)
Image
Copper Stuff 11 11 13 083 by 71240z, on Flickr

One of the seals is obliterated ... lol ... look at the front seal (direction of the threaded shaft).
Image
Copper Stuff 11 11 13 083 by 71240z, on Flickr

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.
Image
Copper Stuff 11 11 13 082 by 71240z, on Flickr

Image
Copper Stuff 11 11 13 081 by 71240z, on Flickr

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.

Attempting to , and we'll see if she spins free once I'm done :D lol.
I like doing some of this stuff even if I end up at a dead end :| :)

I called 3 shops here local and they all wanted basically ... whatever they wanted to charge for the work.
I can't remember the "exact" prices , but the ones below are close.
I had quote for $600 base if internals were good ... $900 base if internals were good ... and a guy that wanted $780 but that's the start.
Of the 3-shops ... 1 shop claims they balanced these (or had them balanced perhaps ?) the other 2 avoided the questions and re-phrased things in a manner that I wasn't comfortable with accepting.
:fry:

I should have a pro-shop do this stuff , but I get the feeling it will be expensive or irreplaceable parts (then I have to pay for their time on top).
Expensive , but worth it no doubt if they're capable.
I can't go expensive at the moment lol.
G-popshop.com didn't have a clue what seal or set I needed ... and said to take it apart to find out or send it in to them (I believe?).
A couple of other shops I emailed (out of state) said they weren't sure , but I had the feeling they knew something without saying it.
I can respect that though really.

The last time I checked = turbo-city lifted their warranty on the 280zx OEM re-built turbos ... " to save you money " .... :|
Around $360 ? or $330 ? I can't remember exact. Will try to see if they still sell them.

All and All I'll just get a working turbo if this process goes bad or a cheapo new journal bearings one.
I've been watching the GARRETS on and off on Ebay (when I had some money mostly lol).
I've also been watching the New generic $130-$180 ebay turbo's out of curiousity like the next cat.
:fry:
(just spin the compressor inlet around and bam ! done... well if it clears the steering box that is ... hahah :lol: )

Good question draker !
I've been looking at all the after-market suppliers today and last night.

Apparently Ai-Research stopped it's division of vehicle turbo's around 10-years ago along with the parts ? (last I checked , but I can't confirm).
It became Garret or something along the way. (If I remember all that the correctly.. I am tired today :| )
Skib said it was a Ray-Jay turbo of some sort which is long gone I think ? (probably with the parts).

I have a feeling I'll probably end up with a G-pop kit like this (or somewhere similiar)
"Complete T3 Kit"
http://gpopshop.com/garrett-t3-t4-t3t4-kits-2/

Ebay has this to "from hong kong" :|
http://www.ebay.com/itm/New-Turbo-Repai ... 1b&vxp=mtr

I haven't looked much further yet
:troll:
I'll see if they're OEM or kits from a manufacturer that got taken over.

I can appreciate your experiment. We've chatted about this before, I think?

I would hesitate to spend too much on a rebuilt kit. The prices on that g-pop shop site look decent. Just keep in mind the price of new CHRA's when you get deep.

I would rather light my money on fire than buy that china rebuild kit. But honestly.. sometimes most of the fun is just experimenting.

Anyway, I am loving the pictures and anyway it turns out... i'm sure you'll enjoy the process.

Oh yeah we have chatted about this before for sure :thumbs:
I took/take what you said to heart , and always kept that in the back of my mind when tearing into this one :lol: :)
Yeah the g-pop stuff does look decent all around for value , but I'm not sure they aren't using the same kits as ebay/china :|
They look more competent at all levels though.

I believe you're correct .... burn the money first ..... efff em.

Oh yeah !!! exactly ... just getting another CHRA assembly makes SOOOOO much sense to me now.
I understand completely why that is now on many levels for sure... thanks for the tips buddy :thumbs: :thumbs: :thumbs:

Hey I appreciate that Thankya :thumbs:

right on enjoying the process at any rate :thumbs:

On another note.
I actually have another turbo I'd like to rebuild/re-seal ? (in the car still) that isn't smoking ... spools up ... etc...
Stock 280zx OEM turbo I believe .. well fairly sure it is.
So whether this current repair/rebuild works will determine the fate of that one.
I'll get quotes to rebuild the other one first though as it could be a different rate since OEM stuff ? (IDK).
