Great write up, I have to disagree about high compression motors though. You said that anything north of 11.2:1 will need race gase and engine mangement. While I agree that those things would be great with the high compression, some of the locals here run hybrid engines with 12:1 c/r on 93 ocatane with stock ecus. Those motors run great, and have lasted well. My build is going to be high compression on 93 octane, but I plan on using a s-afc or e-manage. Just my opinion though, great thread!
