Welll well well

was feeling all fine after recent tuneup, gave her a service myself new plugs etc.

driving home last night going up the expressway hill I had heaps of bad surging (1psi) couldnt boost anywhere near asper normal, and black smoke billlllowing out the exhaust (on boost only)

felt bad, climbed up off boost in left lane.

today driving, same thing. boost is bad (wound down the ebc to .3bar) as soon as it hits 1psi - 3psi it is surging, airflow is all turbulent, and the turbo sounds like its working its head off (not squealing, just 110% load), lots of black gooky smoke and just generally bad bad.

So, it seems my turbo oil seals are farked. When the head was being worked, the tomei oil restrictor in the head meant there is more pressure going thru the turbo line, hence boostwerks said they fitted a better flowing oil restrictor to the Sliding Performance 360degree thrust bearing nissan r33 stock highflow turbocharger, steel wheels with ported housings.

Seeing this had happened previously (ie a few months ago at the garage) Im guessing that would have had an effect on the journal bearings. And now she's starting to die.

An untimely death, but perhaps timely.

You see Im doing a project, twin turbo manifold with twin stock nissan ball bearing highflow's.

Untimely in the fact i cant afford to do 2 at the moment, nor the manifold. However I have already received the new Garrett Ball bearing for the core $140 and paid $99 for a new comp.wheel/turbine shaft set.

thats $239 usd all up, will rebuild and spend some cash on a rebalance at a turbo place like ATS.

However Ive got another dead turbo here kindly donated, and will rebore the housings of this one out at my pops place, and eventually order another bb core and turbine/comp.wheel set, rebuild the donated turbo.

Its just going to take a while before I'll have the funds to do it all, due to intake fabrication required and exhaust manifold and work to flow two dump pipes into one (same with intake, same with charged air to the cooler, need 3x Y pipes)

bad luck that the turbo has started to fail just now (-600 on my visa is all I have got to my name) but good luck that I was already ordering parts.

now back to ripping apart the donated turbo to see what else I may need via a rebuild kit.

oily black smoke on boost = turbo dieing. 20,000kms old, never went past 1.09 bar, but it was only $600 3.5yrs ago plus a dead turbo. Not too bad, seeing now I can make it Ball bearing. Not sure if the 16G compressor wheel will be ok, nor if the TD05H turbine shaft will fit ok. If not its $100 for a Garrett 60-1 comp.wheel and $170 for the turbine shaft. trying the cheaper way 1st. fingers X'd

You 100% sure it's not IC piping? Steve had this same issue on his car, turned out there was a crack in one of the silicon joiners. Check that just in case, you never know

Will do. letting the car cool down right atm, and will spend some time going over everything, put it up on the stands and search, but perhaps I'll start anyway to pull bits off this week.

get to the turbo and have a good look. Just takes me time with no knees and lots of pain, so slow going but have to do it. Stag is coming off the road :blink:

not a problem, cheers tho.

none of the cooler pipes down low look out of place

tomorrow will inspect everything.. not enough light now.

100% sure its not IC tho, felt ic-issues before but this seems different..... want to see the shaft(s) of the turbo.

if its black its fuel dude dont stress, unless just your rear wheel fell off, ive seen a seal go before and its pure white just oil in the exhaust!

ah 'k

cheers for the replies and ideas

will check over in the morning and sort thru it all.

yeah Brendan ive done 2x 90 degree pipes now the 2nd one made me shit my dacks as i thought i blew the turbo even got a tow home from luke to find out we could of fixed it there and then

and i couldn't see the split either till i putted it off

ah ok

hoping its that then.......

will see tomorrow

cheers

cheers ken & andy

tis' ok tho, pulled the pipes off everything to the turbo, cleaned afm pod etc, touch of oil as one pipe gets closer to the turbo (pre-intercooler)

oil all around the underside of the compressor and around the compressor housing, looks like oil seal to me

:P

no shaft play to speak off, comp.wheel and intake look really good nick, so says to me its inside the turbo, oil seal...

will take off the dump and drop the turbo from the manifold shortly, slow-drain the fluids.

all ic-pipes look and feel ok for leaks; definately turbo / oil related.

it isnt the turbo

now looks to me like its from the engine

bottom end may be going, cant tell, but here's hoping its just the oil pump then.

anyone down south have a compression kit available to lend out?

I should buy one but cant till this thursday (disabled pension fyi Kralster, feeding 4 ppl and a morgage on 400pf isnt easy dude)

around $50 for a basic compression testing kit but put my last 50 yesterday into petrol lol !

so. all in all, I now think its the engine NOT the turbocharger

hey sorry wasn't trying to be rude or anything, sorry if i sounded like a dick.

Just borrow a compression kit if you can, that 50 bucks can be better spent on your family. I'm sure someone here can help you out.

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
