Searched through threads for a bit and didn’t see anything referencing swapping a 718 cayman 4 cylinder turbo motor into a 914. I imagine in the near future these engines will start showing up for sale from wrecked cars, etc.

Realize that it is water cooled so cooling would require a radiator like the unit Renegade hybrids sells. Will need to get air flow to the turbo. Also lots of questions about if the engine will physically fit in the 914. Wiring, ECU’s, transaxle, on and on. I get it, it would require a lot of fabrication.

The price of doing a 6 cylinder conversion is straightforward but getting pretty expensive.

The turbo 4 cylinder motors advertise over 300 hp at the crank and it would be cool to have a 914 with a 4 cylinder high horsepower motor.

I bet someone has already done this I just haven’t found anything. Who knows, someday this may be a common swap….

What do y’all think about this idea?

Check out the 914 with an early Boxster engine that recently sold on bringatrailor.com

Looking at the modifications and fabwork done to make it work was quite interesting. Not the modern 718 engine but it is feasible without bodywork and was cheaper than finding a very good 3.2L and 915 transaxle as I had done.
