Too much plug gap will kill your disty, to much resistance/heat.
Plugs and cable? put it at .030'' fails? with new plugs at .030'' or be crazy and put it at .025''

Have you checked continuity from cam sensor to ecu, ecu to disty??
Also it is not that hard to retrofit another disty from any SR20... like 6 wires... i have not done it but i run the RR disty on the ve with one leg cut.
I have couple of disty here... but it is my precious!!
