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

      Biggest thing is you're okay!   It sounds like between the accident, and the drive home, it was a pretty torturous trip again! On the bright side, you took the opportunity to enjoy the event more from the perspective of a spectator, than as an entrant!   Sad to see so much damage to the car. It really has taken a HUGE hit in the front end. If/when you choose to repair, hopefully the rails are straight (At least from shock tower backwards). Hopefully the extra cage coming through there has save most of the chassis rails, and HOPEFULLY saved the motor too. Best of luck when you eventually get motivated to start pulling it down to check it all out

      Slight brake pedal stutter after new pads

      By MBS206 · Posted

      Sounds more like what Brad said, that it's mainly transfer. What pad bed in procedure did you use, and did you replace/machine the rotors, or just swap pads?

      By PranK · Posted

      The stutter is almost entirely in the pedal. I don't feel the brakes release and reapply as you would with ABS engaging but the pedal feels that way, without the brakes releasing. It only lasts for less than a second and the pedal is fine again. It's hard to explain, sorry.  I'll get under this weekend and just double check everything is tight. Fluid is at max where I left it.

      What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!

      Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !
