Turbos blowing?

[tydon]

What are main causes of turbos constantly blowing on a motor I've got a motor that keeps chewing turbos up and spitting them out ? Help please looking at putting a nice vf 24 on it and would like this one to last lol

Blocked or incorrect oil feed banjo bolt/bolts?

constantly destroying the turbos alone sounds like your up pipe flexie is disintegrating. Or you brought redline performance headers. Or your running your bov to atmospheroic and the backfire is blowing destroying them.

Wut ^^

Worth sending it to a turbo shop maybe to get a post mortem done? Ross is most likely right with something relating to the bolts & restrictions etc

Is it a stock setup or twisted etc? Have heard of people angling the turbos on twisted setups to the point of fcking up the oil drain - its not something retarded like an oil drain being part blocked or kinked is it?

They shouldn't be an expendable part unless you're cranking out the antilag

yea saw it happen to a supra. blew up 2 turbos because the cheap headers he brought started breaking up and sending shards thru he turbo then had my mate tell me how it happend to his mates wrx because the uppipe flexi did the same thing. And the atmos venting bov's with out a tune cause the car to run rich when throttles closed and starts the bakfir.

it happens quite a bit

[ADIKT]

Having a venting bov is not going to kill a turbo. Seems VERY unlikely to have multiple turbos blow from a bov lol

Up pipe flexi is plausible.

Send one of the turbos away for a diagnoses and go from there.

I'm putting money on oil feed.

and bang on the money i pulled the oil feed bolt out and holy crap it was blocked it was the turbo bolt with the 1mm hole i put in the one from my other wagon which i knew was good and got it all going and was freaking out the whole time waiting for the turbo to go bang again lmao. but nope seems everything is allllll gooood haha thank fk.

[tydon]

all the previous turbos would blow after 2mins driving to. and the shafts in the inside of the turbo snapped

[Guest]

If the turbine shaft doesnt get enough oil it gets hot and breaks iirc. Shaft should look like it got really hot. You know if you remove the filter then that crap thatgoes thro the turbo bearings so next failure will be thro contamination.

Yea it looked shagged as like you described above all of the turbos had exact same symptoms . I used a new banjo bolt and line
