I'm certain $10k was a deal considering no car manufacturer is selling a setup nearly as awesome as yours. I've almost got my CRX back together after putting in energy busings, new shocks, lower springs, camber kits to front and rear, then time for my aero!! I've sourced a low mileage VX swap for cheap and am picking it up this weekend. It's missing the O2 which I can't seem to find in a junk yard anywhere near here
and the ECU. But I'm going to tune my ECU anyhow and rather than try to figure out how to make closed loop 5 wire O2 from VX work in it's stock state(2nd cpu inside stock ecu as wideband) I think it may be better to get a p28 and put your chip in it. Vtec-E should run just fine off a 4 wire O2 and tune, correct?
