Torsen Lifespan?
#2
I was always under the impression that torsens didn't wear out, but could be wrong. I did have one start acting kind of weird on me, but it certainly could have been fluid/abuse issues.
For a couple datapoints, both cars lived most of their turbo life in the low 300hps:
I bought a '99 at 100k miles, turbo'd it and put another 50k on it. It still worked fine in general, but toward the end of it's life occasionally it seemed like it would want to not lock up when it should have (making a turn from a stop in the rain one tire would spin for a second before locking) or lock when it shouldn't (driving through a parking lot it'd sometimes skip the outside tire for a second like a welded diff would do).
I bought a '00 at 160k miles, turbo'd it and put another 10k on it. It drives great, very seamless. Locks up when it should, opens when it should, no issues with it at all, just under 170k miles.
