Milling the head should give me an improvement. Is there any published data on what to expect?

Wow Jim. Cool work! As for the MPG targets, I would think several known effective aeromods would be a breeze for you with the skills and verve you demonstrate: lower the ride 2-3 inches, put on a belly pan and/or an airdam, get LRR tires and pump them up solid, and make good aluminum rear wheel skirts using a wood hammer frame. And lastly and more involved would be to create a fastback using a donor car like some of the Miata tuners do.

But the car is cool as is too and 50mpg is a really good number. What did it originally get? 22mpg? 27?

[EDIT: correction. I wrote "Miata tuners" when what I was thinking of was Mazda in general. I think it has been mainly other models that have been chopped and "fastbacked" using donor vehicles.]

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
