Since souping-up my R16 is a long-term goal, who has a formula for a
good combination stroker crank/piston/etc, camshaft, head mods, and
better breathing? Is there a do-it-by-the-numbers approach to better
performance without losing much low-end driveability, or is each engine
different, even if we all start with a stock R16 and add U20
crank/pistons/etc.?
Would I be better off to simply maximize what I've got by reducing
weight and drag as much as possible (i.e. electric fan, get rid of smog
pump)? Maybe I should just leave my engine alone and stop eating those
hamburgers and fries (17lbs = 1hp net, according to Bob Sharp).
