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! |

Just measure your deck, Then like me measure about 15 more times. CC the heads. stock are in the 62 CC range. If the deck is to close you will crash the pistons into the heads.
Someone said you can mil some material off the piston crown of bus pistons to lower the dish (which is 10cc BTW) US is 5cc and euro is actually 2cc although they look flat. |
