I went to PickNPull today and found a Pierberg bypass/blowoff valve.

I was going to buy it, but couldn't get one of the nuts off (didn't have any gripping pliers). Is anyone interested in it? Does anyone know what it might sell for on ebay?
AFAIK they're fairly rare. The diaphragm works, the counterspring works, it seems fine to me.

2 questions:
1) Does anyone know what sort of turbo has the word Da Research stamped on the output housing? It has a 3 stamped on the inside of the output housing.
2) Did an 88 760 have turbo plus or a turbo from the factory? This car had an airbox t-stat set up and the turbo. It looked like it had a new radiator and was a failed project car (and the pierberg valve looked like it was added by the vacuum lines). The water pump had a ton of corrosion and I suspect it had a huge coolant loss and died.
