OK, working on the least intrusive (and admittedly least effort) tests first.

I disconnected the wastegate control line from the top, and tried to pressurize it to see if it would hold. It does not ...

Sometimes I wonder if my alternator mount is missing something in the tensioner department, although I don't see anything in the parts diagrams. With the AC compressor, there's a normal tension adjust ...

What's the best way to access that with the turbo on the car? Remove the compressor-side intake tubing?

If you can get in there, see if you can turn the compressor wheel by hand...

Some boost controllers work that way, essentially. I tried to access that area once, but I don't see how you can get at it from either top or bottom, without removing it from the car.

If you have a ...

Very good idea...something I can try that doesn't require hours of work that may be pointless!

I do not hear any turbo sounds at all right now, and when it was working, I could hear it prett ...

Just out of curiosity, with a wide-open stuck wastegate, should a stock S2 turbo be able to flow enough to get positive boost?

And on the other end, with a wastegate stuck closed (or a disconnected ...

Interesting...I don't have the black seal, but I did once pinch the orange o-ring on reassembly, and the car would barely idle. I'm certainly not seeing that, as it seems to idle and run fine. I'll de ...

Supposedly, this turbo was rebuilt or refreshed or something a few years before I got it (seller didn't have details) so I'm certainly hoping that's not the case. But...yeah, that would do it...

Isn't that an NA 924 part, as opposed to the turbo? I saw that too, and it was listed as compatible with my car, but...I don't see that part on my car, or in the parts diagram for the turbo, with the ...

Very good point. I'm going to kick myself if the overboost is a leaky control line...

Overboosting as you describe c ...

Can that be done in situ? I'm not actually sure what/where that is...

Sounds exactly when my recirculation valve on the turbo got stuck due to a broken rubber seal. Pretty easy problem to fix.

Lately my alternator belt has been losing tension, and squealing. I'll tighten it back up, and it will be fine for a while, and then it starts again. While messing around with it, I noticed that the r ...

Maybe we should just consider it a badge of honor. "See that ding? That's 'cause it's got a Custom Suspension!"
