Is it possible or practical to do a 930 or 993 Enigine swap into a 944?

No, it will not fit that engine bay. The 911 engine is much wider and lower than the 944. The only way to do it would be to cut the whole front off the car then fabricate a custom space frame with mounting points for the bodywork, engine and suspension. At the end of this massive very expensive project, you will have a bodged up car that handles worse, not much (if at all) faster, much more expensive to maintain and has no residual value other than the 911 engine (assuming you don't have to modify that. Just buy a 911 if you want to drive a 911 engine, it will be much cheaper and much better than this.

Thanks man, so could i fit any other boxster engine like an Impreza or anything other than a LS cause quite frankly I’m not fond of American V8 and I also just want to make something extremely unique without it being impractical.
