Well, it's all KKK- the hot side & bearing housing is stock 1980 931, the cold side is from an early Audi (same compressor wheel specs). All freshly rebuilt

And here's the BOV that takes the place of the original built-in pop-off valve:

The BOV is a very nice unit from Forge Motorsports (thanks rennlist groupbuy). It comes with a few springs to set the opening psi.

More to come later.

ps- don't pay attention to the orientation, I still need to clock it

Very nice job, but if already have taken the "hybrid" way, you could put something more beefier there

That valve is what I use. Very nice and more than capable for 600 HP.
Turbo looks good.
