Welcome to 930.

That car has been showing up on Craigslist for a while now. It looks like it can use some TLC, and you're going to be giving it. From the pictures I noticed rust on some of the intake components of the engine, which is sign that the car spent a good deal of time outside.

Does the boost gauge work? I looks pegged to the right in the photo of the dash...that's not where they normally sit. You asked about detonation. The sound you described could be detonation. Verify that you are not overboosting. Factory setting on that car was 0.8 bar, and going over that is not recommended, especially without an intercooler. Verify timing is set correctly, and if you can, check the AFRs on boost to make sure your mixture is not too lean.
