So far you've all managed to skip his original Question. He's asking about the whole nine yards. Yes, NGK are the recommended spark plug and will allow him to upgrade his ignition without worrying about the plugs. Yes, Nissan had it right from the start but times change and parts wear out. Stick with the NGK brand Plugs, possibly go with some upper end plug wires like Accel 8mm or better for some real good current transfer. The 79' 280ZX distributor ( with E12-80 ignition module, and possibly a D4K8 or D6K8 dist. body) w/ new cap and rotor) would be the next best way to go. The D6K9 has 2 vaccum advance pieces on it (used in the 80' 280ZX) Also, Pertronics make great parts for your ign. system and lets not forget about MSD. Both make excellent upgrades to any "stock" Z or counterpart. Hope this helps at least a little, Dave. P.S. I just put the D6K8 distributor w/ E12-80 ign. module in my 70' 240Z and you can't wipe the smile off my face with a sledge hammer. I now have more power, NO more points (yeh!!) better gas milage, quicker easier starts (even in the cold weather) and the performance is 100% better than stock!!
