Ferrari Mailing List: Re: NFC: Z32 300ZX turbo lifespan?

[Ric Rainbolt (ricrain]

I have experienced the "let go" turbo twice. Once as a driver on an 
MR2 turbo (~55,000 miles). Once as a passenger in an F40 (~8,000 miles).

In both cases, the turbo oil seals let go without much warning. Once 
they did let go, boy was it a sight to behold. Most turbo rebuilding 
services don't charge that much, but the labor to get the turbo(s) 
out can be a real cost factor (easy on an F40, difficult on a 300ZX TT).

I have a friend with a 91 300ZX TT (~85,000 miles). It still runs just fine.

It may go another 100,000 miles before a turbo failure or 100... 
there's no way to know. How hard was the car driven? How often was 
the oil changed? Did the owner let the turbos idle down? etc. etc.

YMMV,
Ric Rainbolt
