Boxer engine question

[Psychographic]

I made a fantasy boxer engine from the engine out of a Jo-Han Scrambler kit. Do boxer engines usually have a common location for engine mounts, if so where would they be?

Boxer engines are typically rear mounted: Chevy Corvair, Porsche 356/911 or mid-mounted Porsche 914.

It depends on the specific engine design, and its weight in large part.

Early VW and Porsche flat fours, for instance, have no engine mounts per se. The flywheel end of the engine is bolted to the transaxle, which itself sits in a cradle mount bolted to the frame at the engine end, with a rubber snubber mount at the other end.

The 911 flat six is the same, but due to its greater weight and length, it has a steel plate cross mount bolted to the pulley end.   

                                                    

The VW 411 flat four uses a similar pulley-end mount, as well as bolting up to the gearbox, both in mid-engined (Porsche 914) and rear-engined applications.

The Porsche 964 / 993 mount is similar, and becomes progressively more complex with newer models.     

 

Big fat heavy boxer engines like Ferrari often have mount ears cast into the lower crankcase, or cast-in bosses to accept bolt-on fabricated mounts, and typically sit on a steel subframe. You can see the rubber mounts clearly, below.

Thank you gentlemen. I'm going to use a mount like the one in the Ferrari pic.

That's quite a neat looking engine!
