Purchased a 50 degree VTC gear and a small cylinder I can stick inside to prevent it from advancing more than 40 degrees (for valve/piston clearance reasons). Need to order a few other bits and pieces, I've been accumulating everything at a shop in NH. Waiting on my final drive before I start assembling.

Drove back and forth to Boston over the weekend. On the way there, I targeted 80mph and averaged 57mpg, with intermittent A/C use. On the way back I was able to approach 80mpg with a target speed of 65mph (cruise control, no P&G) until I started climbing the mountains. Many of the mountains in Vermont require WOT 3rd gear or, in a few rare cases, even 2nd gear to climb with the Insight's 1.0L, and this takes it well outside of its peak BSFC range. Can't wait to see what I can do with the 2.0.
