Easy salvage in Emeryville is great if that's who you're thinking of, though I've generally just picked up new parts when available from Pelican or Sunset. I've been having a blast in it since January. I can't believe how depressed the market is for them - I got a pretty unique deal on mine, but even without that, I can't think of another sub-$10k car I'd rather have except maybe an E36 M3.
The car has actually been very trouble free after replacing the alternator, battery, master cylinder, DME, timing belt, water pump, thermostat, and every piece of rubber under the hood. I'm still rolling on 9yo tires which is a little scary in the rain, but I can't blame that on Porsche.
I'm also still not sure I'm seeing boost as early or hard as I should be, but I don't have a ton of turbo experience and haven't driven another 951 to compare. With my novice footwork, I'm pretty sure I'd be faster in an S2, but the turbo is definitely fun.
