Nah that's cool zig-zag. There isn't much more to it really, I'm looking at a handful of Nissan heads to begin working on a cross flow A-series head. This week the SR20 head was on the bench so I decided to snap a few pictures while I was measuring and cc'ing.

Nothing will happen for many, many moons yet as I don't have the cash. But when things get better financially I'll have a twin cam A-series.

I have access to a 3d printer now and have been developing a few smaller things ready for later. I can basically print a plastic version of the trusty A12 head, amazing stuff. You use these models as samples for when you actually consult an engineer so they have something to look at but the general idea is that I get it done bit by bit and then start throwing money at it once uni is over.
