Watercooled Porsche engines

[yetibone]

I got my hands on a '97 Boxter engine about 3 years ago. The engine assembly as a whole seemed much heavier than an aircooled flat six. I can't say it was any wider, or longer. If so, only marginally more than an older 911 engine. It was certainly taller, and had an oil sump below the crankcase. The flywheel, clutch, and transmission mounting pattern were unlike any aircooled Porsche, or VW. I believe it had a two piece flywheel. The starter motor was on the engine instead of the transmission bellhousing.

I don't think it would easily work in an old Volkswagen, or even an old Porsche. I don't believe the performance would be in line with the expense.
