confirming that those are 944 turbo pistons.
those were 8:1 compression in a 944 and a 928 has 2mm or so more deck height - youll be way down in CR or need a longer rod/stroke to bring to the deck.

I think the P.O. had supercharging in mind, but not sure. His goodies also included a cross drilled 5.0 crankshaft. I'm wondering what I could build with those a starting pnt.

We saw a German build like that recently posted here. Koenig?

However, I don’t think it’s cost effective build in the current parts pricing situation in which the (IMO poorly designed) GTS crankshaft is prices in $x000’s not $x0’s.

It’s just my personal opinion that the GTS crankshafts should not be going into our engines, they should be coming out of the engines. The counterweight arrangement compromises the main bearing loads and crankcase gas movement in favor of lower manufacturing costs. It’s pretty much the worst designed forged V8 crankshaft that I’ve seen in person.
The price that used GTS crankshafts go for makes no sense to me, before you consider their low production numbers. I’d be selling, not buying, the original GTS crankshaft.
Now, this probably doesn’t matter at rpms that these engines see. It’s just one of my pet peeves: S4 crankshaft is a great design and then they laid an egg like the GTS crankshaft.
