2.7 CIS Motor

[pcar916]

If you do decide to use that motor there are plugs for those air-injection ports. Engine Builder's Supply used to have 'em but they were available from lots of folks.

I had a really nice 2.7L (Bruce Anderson spec) motor in my 914 when I bought it. It was great fun and built to overcome the limitations of the original. But it'll never have the legs (mileage) that a later motor will. I'd never put less than a 3.2L motor in one now unless a really fun 2.7 cropped up. Any more I'm used to having more torque. Kinda makes going back a bit tough.

To build a 2.7L motor up properly will cost as much or more than a later motor, although the conversion costs differ a little. The magnesium case has to align-bored (and possibly shaved first) and after oil pump updates and other mods you will still get a motor that can't last as long as a newer one. For some years shuffle-pinning was recommended for those cases until it was discovered that there wasn't enough of a "boss" (material surrounding the pin) to keep lots of the cases from cracking at the pin.

All of this said though, the sound of a 2.7 and smaller motor through a sport exhaust or megaphones is impossible to duplicate with a larger motor. I miss it.
Good luck
