Hey all driving on the highway today and my turbs went. Drove it 25km home with no boost and upon quick inspection i had blown the front compressor clean off the shaft.

f**k knows if the exhaust wheel is still on ill pull it off tomorrow morning.

Questions I have is before i buy a new turbo and slap it on why would the other one blow.

It was an r34 neo turbo on my rb20 and was running 11-12 psi.

its been blowing smoke lately. There was a small oil leak from the bottom return line (from turbo to block) but checked bolts etc and all was good.

Seems strange to blow just like that without warning.

Could oil through the intake system cause it to blow or would it be more conceivable that the oil in the intake was caused by this turbos seals?

Thanks

Yeah I will tomorrow

It is very bemusing to me....

Havent been boosting it much like said before only running 11psi.

The oil is the big worry for me engine has been running good just fair bit of oil in intake etc catch can filled up fully after turbo blew.

Trying to chase up a high flow turbo now.

low oil levels in the motor itself, which would be related to a leak... or someone not filling it up enough etc.

many factors. But its only one possibility.

Best way is to get the turbo out, and send it away for inspection so you know what caused it.

Check oil feed line isnt blocked. have you got the compressor wheel? have seen front nut come off and cause wheel failure.

yeah sounds like a good idea.

No point putting on a more expensive turbo only to kill it too.

Am I the only one thinking a bigger problem may come from this?

If the COMPRESSOR wheel has gone, it is surely going to follow the path of the air.. through the cooler and in to the engine.

Lets say it hit the cooler, and some bits went through it and ended up in your engine..

You’re game driving it around with bits in there..

mm, fair point.

Mine cartridge failed and the comp wheel ate lots of the front housing out, no harm done to my motor :thumbsup:

But i guess it depends on if it totally fell off, how long it ran for, how muhc of the comp wheel/housing is actually missing

if it snapped the shaft you definately have an oil feed issue.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
