This is what I came up with. The first gen insight and Civic VX have almost identical curves, the gearing is all different, but the final rpm and mph is almost identical. All curves are in 5th gear.
Its interesting that the CRX HF is 228 rpm less at 65mph than Civic VX and 1st Gen Insight.
Also interesting is how the CRX DX is 917 rpm more than the CRX HF at 65mph.
