If it is just one turbo it is somewhere between 1988 and
1992.
It makes a large difference. If it is 1990 to 1992 is
better
as the first ones 88 to 90 cracked a lot.

Paul here are some pictures. Please tell me what I have.
If you need a different shot please describe it. I'll
try again.

What was it specifically that cracked, something I need to
inspect during the rebuild/porting process?

'87-'88.....Need injector color to tell which year
now.

The engines on eBay that look axactly like the one I just purchased (off eBay)are
described as 89-92 S5. Intercooler looks the exactly the same anyway. My engine
is on a pallet in the back of my pickup, and I won't have any better acces to
anything until I can get it out and into my hangar. waiting an a friend to help with a lift.

yes they all look alike. But that turbo bolt pattern is '87-'88 Mr. Smith
I'd be interested in the rotors if you ever take it apart.
