I picked up a Turbo, dump pipe, intake system, wastegate... everything basically

from a 300zx turbo, for a very good price.

The plan is to make a L24e with some fancy stuff done to it...

the question is, What is this turbo?, it has a water cooled center, oil inlet and out, ball bearing..

its almost the same size as a R33 turbo,

Can anyone help me? it is really hard to find info on it...

like what does it flow, the AR etc...max psi (17 i think...)

its in mint condition thats why i bought it straigh up, without researching it... at the price it was too good to pass

Cheers,

MAG86 :action-smiley-069:

There are many varieties of this turbo. It'd be better if you could give us specifics of exactly what car it was from. Or better still, even pictures.

there is the turbo from the twin turbo z32. These are very very small turbos.

Then you have the vg30 from the leopard/gazelle (i think that's the model). It has op6 on the rear housing. It is ball bearing. The compressor side is similar to the rb20 turbo. It's laggy, and doens't have much midrange, not much topend either. The rb25 turbo is better.

there is also a bush bearing vg30 turbo. It has 45 v on the exhaust housing. Similar to the ball bearing one. Laggy, not much midrange, not much topend.

There is also one of the bush bearing ones with a inconel rear wheel.

i will get some pics asap...

it was from a 120,000km 1984 300zx turbo (Z31) wreck...

it is eventually going on my hybrid L24e (2.4lt 7.6:1 comp ratio)

the turbo outlet doesnt have a flange on it, just a lip on the end of the 'pipe'

im not after massive pwer, just some more grunt...

here is the only pic i can get... its exactly the same as mine, even from the same year 300zx turbo(my mate is stripping one..wont sell me anything though)

we tried to un-bolt the exhaust section off the back... and it is the most hardest thing to undo, we soaked it in WD40, hit it, blow torched it, and those bolts will not come out....

how do professionals do it???

is there a recommended way of taking one apart? (im stuck as you can probably see...)

The way to remove the hard bolts is Snap On spanners, Rost Off Ice and oxyacetylene :)

It appears to be the bastardized VG30.

A completely useless compressor cover and wheel from the RB20 turbo with the VG30 rear housing.

Made by Hitachi for Nissan Motor Co.

Ball bearing.

Ceramic turbine wheel.

As stated above.

It isnt all that special and pushing it past 12 psi would end in failure pretty quickly.

An RB25 turbo would be considered an upgrade from that.

So it aint all that good then??

I only paid $150 incl. pipes and some boost sensor looking thing

is there anything i can get done to it to make it perform better or is it not worth it??

AARRGGH!!!

i had it allout on my workbench last night, and the cat knocked a oil filter off the shelf and it landed on the compressor wheel..... bent a corner of a blade like it was playdoh..... i tried to bend it back with pliers... SNAP!!!! ( plus it was 3am as the wife hates it when i work on stuff)

so now there is a 3mm x 4mm piece snapped off.... the rest of the blade looks the same as all the others....

Now is this areally bad thing? or will it be fine?

Im only looking for a nice upgrade from the 80 or so kW i have now, so guys im not after massive power (yet). i seriously wont be running stacks of boost either.... probably wont get any bigger than 2.5 exhaust too

You had to play & now you have to pay! Simple as that.

Out of balance at 100,000rpm and it will self destruct.

Maybe you should have been working on PUSSY and not cat and maybe the wife might be a whole lot happier too.

Send it off to Mr Slide for a rebuild and a parting of about $800.00

You lost this round mister.

Cheers, D

      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

      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.
