switching 16v head with an 8v?
I have a feeling I already know the answer but...
Is it possible to fit an 8 valve head onto a 944S block? Sorry if this is a dumb question, but a local junk yard is willing to part with an 8v head for like 30 bucks...My 16v head is cracked, but working, so I'm contemplating this option.

I don't think they are...
The issue that would concern me is whether or not the cooling jacket will line up.
On another note, how much did that engine swap cost you, if you don't mind my asking? Is there another thread about it?

yeh all2.5's have the same gasket profile .so you would need single cam ECU or try mount the cam sensor on a single cam engine either way single cam is a bit of a stup backwards unless your thinking turbo .
but if that is were you at i would sujjest posting on the turbo forum try swap your head and manifold for turbo head and manifold's as there are peope with surplus turbo stuff and there has been talk of tiwn cam conversions .

S2 guys pay good price of your exhaust cam, because it gives some additional hp when installed to S2 head.
Plus the 944S exhaust cam is an excellent core for grinding a hi-perf cam.
Don't sell under $400 a piece.

You can't just transplant the S DME, with a 8V DME. The S uses a 60-1 toothed wheel on the flywheel and the 8V uses the starter ring gear with 130 teeth for the toothed wheel.
