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! |

Thanks for the tips so far.
I imagine that I CAN NOT remove material from the head surface to increase combustion because of the design of these motors? If I remove the 0.08" from the cylinders, will the push rod guide tubes put up with that, or will they have to be modified? ***THis is a beater motor that I'm doing a quick and nasty rebuild on. I only want another 2000mi out of this motor over the next year. 914Guru - Do you have all the cyinder displacment figures for preforming a compression calculation on a 914 2L engine? IO have a calculator if I had all the figures. Thanks! |
