Vg30et Bb Turbo Info Needed

[Factory 5]

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,

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...

If you post up a couple of pictures i could tell you what the turbo is straight away

If it has ceramic turbine i would not run over 12psi boost as it will seperate from the shaft.

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...)

[Slide]

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??

You should note that Z31 turbo's did not have a BB turbo fitted standard.

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

If you've broken a fin off or part of one im guessing it will no longer be balanced and will need to be repaired.

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.
