I am a little late to the game. I just found out about your project. I think it is awesome and I am excited like everyone else to see what comes from this. I have played with K-series hondas so this is that much cooler to me. I am wondering if you have thought about using the varible cam system from the k motor? Maybe I missed that reading through 20 pages. It seems like you are basing as much as you can on the K motor to help your development. I wonder if you have seen this? It is a K motor varible cam running on the F series honda (s2000). They made some of the missing parts external and might work here too. Would be neat to add something similar down the road. Whatever you do the finish product will be amazing.
