Wrench,
Does this airflow limitation have to do w/ either the stock throttlebody or the Air Flow Meter? If I go w/ the Megasquirt system, I'll use the slightly bigger Nissan Throttlebody (60mm vs 55mm for hte stock TB, I believe), and I'm hoping I can eliminate the Air Flow Meter altogether (if that's possible w/ the MS system).
Or, is the flow limitation a matter of valve size? I was also thinking about goping w/ the 2.0l valves to increase the breathing capability of the engine. Do you think that would help?
