Earl, the "big jump" in times for Neil came due to some serious suspension tuning. It was not motor. They went WAY high on spring rates, I think they are over 1000 lbs up front and 500-600 rear (don't quote me on it).
That and some off season work with data acqusition got them 3-4 seconds at VIR. It's not motor -- I've driven off from that car in a straight line. It's handling and driving.
Based on what Neil has done I still think a too the max 240sx can win. The Miata guys have raised the bar, but I don't think the Integra, the CRA, the SE-R or the 240sx are done just yet.
