Huh. I presume your '89 was white? Mark Anderson bought that wrecked '89 and I bought the GT engine out of it. It's now the stroker engine in my GTS. Did the shop rebuild the engine? It had an oil pan from an '83 on it, and the main bearings had been replaced before, when I pulled it apart.
The guy after you did a real number on that car.![crying](https://rennlist.com/forums/graemlins/bigcry.gif)

Mine is a 89 s4 from Japan and it has the GT stamp on its head, I do not believe (but not sure) it has the GT cams.
Drop it in and tune it if needed, I bet it will be fine.

Brad-
If you have GT cams, there will be an '01' stamping on the rear end of each cam, like so. If it says '00', then you've got S4 cams.

I'll just resurrect this thread with the outcome...
The GT engine arrived in pretty poor (external) condition so I stripped it down and replaced all gaskets and seals etc. The water pump plastic impeller had separated from the shaft and just fell out! The GT cams looked fine so stayed in. The cam gears were as new
but the plastic bushings in the tensioner arm were missing! The fuel dampers and regulator all leaked and injectors were clogged. Not too shabby then!
So the motor is now finished and in the car. Once the injectors were cleaned the car starts and idles very well, no problem with the S4 LH. Car seems quicker and smoother than before, or maybe I'm just kidding myself! The LH and MAF were rebuilt by Theo so that probably helps too. A few photos from the other side of the world then.
