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.

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
