Factory Turbo Life

[GD2ILA]

Hi Everyone, just a newbie question.

I know it all depends of how much boost your running/how hard you drive ect... but please i just wanted to have a rough idea of when peoples standard turbo died or started to have problems? I've done 135,000km on my factory turbos have been boosted since 27,000km . Been told they normally last to about 150,000km before they require rebuild/replacement or upgrade is this correct or just a myth?

What do you mean by boosted? 10psi,20psi,30psi???

And are you referring specifically to the R34 gtr? or 32/33 gtr as well? because they are two totally different designs.

Hi mate, just r34 gtr's ceramic.

Boosted as in anything which isn't standard.

Was told my turbos's would last till about 150,000km till they'll die, just wanted to know if it's true or not. also wanted to know average turbo life.

Admin,

if thread/poll is useless please help answer my question than close.

Thanks

In my case it's an RB20 turbo that has been running around 14 psi since 23k and is now up to about 150k. On that basis, being ceramic, it is one of the unusual ones, because running that sort of shaft speed for that many miles/years will break most of them.

The question, especially with regard to ceramic turbos, is a bit of a waste of time, because the real failure rates, like any real failure rate, assume a normal distribution with a mean value in the middle and the extreme left and right hand ends of the distribution (covering the best and worst 5%) can be very very different to the average. And that's when they all get treated the same, let alone the different way that all the Nissan ceramic turbos that have ever failed got treated.

This is a question that simply cannot be answered.

There are so many variables. Even things like cooling down correctly after hard driving can have effects, servicing, driving style. Also the tune (heat) can affect things.

IMO expecting stock GTR turbos to last 100k kms in a modified state is begging for trouble and failure, which can take the motor with it.

in a factory state, 200k kms+ can be expected. AND by that I mean 100% factory not even an exhaust

I read somewhere that the Nissan recommended service life on a stock turbo on a stock car is 100,000km? Yet how many cars see so many more k's at 10psi without dramas? And how many don't? As Ash said, no straight answer. Alot of people run ~14 psi no worries. Some run ~7 and have dramas....

i realised it's one of those how long is a piece of string questions, but Ash answered my question "IMO expecting stock GTR turbos to last 100k kms in a modified state is begging for trouble and failure, which can take the motor with it.". From new to 125,000km car has been perfect but lately things are starting to die as my km are getting higher now eg. split boots/cv shaft/just got new brake rotors, what else is likely to go? what else should i look out for hence the question regarding turbo.

Sorry to derail but has anyone noticed how much more life factory turbos from imports last compared to the xr6t? I have heard many horror stories of XR6T turbos dying at like 5k, 30k and pretty much under 100k km's.

I had a stock r32 rb20 turbo at just over 300k before it shat its oil seals; for about 150k it ran 11 psi and saw a lot of track time.

[R31Nismoid]

The XR6 turbo issue was a Ford problem, not a turbo problem.

It was only on a few models (forget which), and it was to do with a restriction with oil feed/filter or something in that department that over time caused damage/failure.

[paulr33]

the factory service interval that nissan specify is a simple regular hassle free maitenance program

take for example my gf's swift. they spec to replace the air filter panel at 40,000kms

obviously it can do much more and it looks like, but the spec is to replace to maintain optimum and hassle free maitenance

the main sevicing components on the turbochargers is probably the bearings and oil seals

my gtst has 240,000 but its far from prefect with the std turbo

it blows some smoke on boost and uses a bit of oil (oil seal probably dead on the turbo)

so it still works, but its far from optimum

i see no issues with factory turbocharger servicing ie at 100,000

but no one does it (including me)

[N1GTR]

servicing factory turbo's isnt really spoken about much, i've always put that down to the cost of doing that vs the cost of buying new.

Too many benefits with buying new, newer technology, better response, more power etc
