Common reasons of 1JZ Turbo Failure?

[Ma70.Ent]

What are the most common reasons that they fail/blow?

 

[AF1JZ]

Some of the parts are made from ceramic. Mine are still doing good though. The spool is awesome on them and I'm at 11psi.

The most common reason the 1JZ turbos fail:

....it's a 1JZ turbo.

heat...old age ... abuse ... ceramic blades

 

[OneJSupra]

As with any other turbos that have over 70k miles and god knows what abuse it's been subjected to it will fail...

What I like to know is why the rear turbo is the first one to go in most cases?

they've been rode hard and put up wet.. only take it for so long

i thought i read something about a recall on the 1jzs that caused the rear turbo to fail.... talked about it a few months back

the PCV system was revamped with a new valve (the 2jz gte pcv valve is a replacement) and the breather on the passengers side valve cover changed location slightly on the turbos intake pipes.

FWIW, my 1jz has that issue addressed but my turbos whine a little, probably will blow in a few months (hopefully not sooner). as of now however they burn no oil and boost great.

My 200,000 mile turbos are on some elses car already, no smoking at all. High EGT's from higher boost will kill them if you dont have the right octane gas.

:cry: my tubos are blown on a supposdly 40k mile motor. they shoot alot of white smoke under 2k rpm.:cry:

Sounds like my car..... I wonder if my new set of twins will be the same.

 

[Syris]

Has anyone sent theirs in to get rebuilt? If so how much did it cost? Where did you send them?

hmm

$1000 for rebuilt factory twins or $1000 for a cheap single setup i wonder what everyone picked.....

 

[Dylan JZ]

actually it all depends on how sexy you are.. mine will last a long time.

kinda makes you wonder about the guys that start up their cars with twin failure.. I would hate to ever run into any of them
