Oh! My mistake
I do not have to regrind the cam! What I can do as far as the single intake valve is either cut a lobe off or take the tappets out, according to Hardline. He has hypothesized that taking tappets out is one way to deactivate to a 2 cylinder.
Moving the timing belt around a gear tooth or 2 is even cheaper

On my Talon the turbo gives me a 11% increase at 1psi in combustion efficiency over N/A. The more boost I run in lean burn the more the efficiency goes up.
So with your build you could run it in N/A at light load with a Atkinson cycle and at mid load still keep it in lean burn, but you would gain back some extra torque?
Hmmmmm. Must Ponder this.......

This seems like a possible idea! An 11% increase in combustion efficiency sounds like a huge jump! Factor in the Atkinson cycle will provide more C.E., and you have quite the efficient engine.
How on earth would I keep the boost so low? Would I have the turbo wastegated at 2 psi? Big turbo?
Also, if my engine responds decently well to becoming a 1.0 2 cylinder, would this mean I could run more boost at low rpm? There's so many variables to consider!
All I know is for the time being I want to get the wideband installed and get lean burn working better than it has. I am seeing no increase in mpg so far
