Having never worked on a air cooled engine before I'm wondering if it's possible to increase compression of these motors in the same way you do with a conventional watercooled engine.
IE - Head shaving or piston changes? I've got all the bits from a 2L transporter engine that I'm going to put on my 914 EC case motor. However this will mean I will only have 7.3 : 1 compression still. I'd "like" to see it around the 9.0 region but I'm not sure if I can accomplish this without pistons. Has anyone got some feedback? Can I pull this off? Thanks! |

the cylinder heads can be cut, but it's the same effect to the pushrods/tubes, not too sure how much you can get away with, I'm guessing the pushrod tubes would be okay with that modification
each engine is different for the compression, you need to know chamber CC's, the deck height, bore and stroke |
