i used the crane cams xr 3000 and to me it works better than the other things my mechanic has instaled i hate dealing with ignition systems but this was so simple to instal and worth it my car got a great boost in spark and power by just adding the xr3000 and the taylor wires ive had it in my car for about two years and i only had one problem i melted my distributor cap but it was the cables fault the coil wire wouldnt stay in it would slide off slowly so it increased the gap size on the cap and wire so it melted it so i just cut off the rubber boot around the cable and stuck it all the way in but no problems with the ignition the only other thing is its $150.00 kinda pricy but worth it

I am looking into the 280ZX solution too. My only decision is whether it is worth the extra money to use an MSD box as well.

According to jmortensen, it's possible to run the 280ZX dizzy without the E12-80 module if you have an MSD ignition box. Apparently the MSD can be triggered by the either the E-12-80 module or the pickup coil alone. I plan on trying this at some point but haven't yet. Here's the thread where he made this statement.
