Hey y'all it's been a minute. Just want to maybe help someone out on how to not blow your PS2 early.
Recently I heard a terrible sound and suddenly lost a little bit of power. That was followed by a horrible whining sound almost like a siren when I accelerated. I thought I blew a charge pipe but after I got under the car all the pipes were fine.
I thought it may have been the clutch and luckily I just had that replaced by a dealership but after having the master mechanic listen to my engine with the hood open it was clear the turbo was whining.
I think the way that I blew the bearing in the turbo was my flash settings. I had the downpipe settings configured wrong. I have my stock downpipe on because I recently got smog'd. I think I caused too much back pressure and too much heat and killed the bearing. So be very aware if you're running your stock downpipe with a tune.
The good news is I'm replacing the turbo with a new PS2 and the upgraded pure turbo pneumatic wastegate. You can bet your ass l'll be running a DP until smog time.

HMU if someone is selling a DP or knows of good deals.
As always watch out for other common failures:
- oil starvation
- debris in the oil
- debris through bad air filter
- high heat due to back pressure, running a stock cat
- overboost, bad tune
- don't idle for too long on cold start
- don't get on it until your car is at operating temps
