questions about a 930S Turbo engine
 

I have had the engine dropped(you can see the pics in my thread called " had the engine and tranny dropped") the shop said its a 930S turbo euro engine. apparently these aren't your run of the mill 930 engines as it has some 935 parts on it and shims in spots that most engines don't have? just wanted to find out if any of you guys knew anything good, bad or indifferent. thanks
