Nice, thanks 😉 looks like the 280zx unit is the way to go, then. If the rear of the switch doesn't exactly like up with the harness I can get creative, not my first rodeo there!

I have a 1980 510, and both the keyed part of the ignition switch and the rear electrical part are hopelessly locked up. It looks like the unit for a similar year Z or pickup is visually identical (and also readily available), just wanted to know if anyone knew for sure. Once again, I need the entire unit with the locking collar and everything. Thanks!

Sweet, thank you! The previous owner had basically done all you described, just never got to attempt to crank it up like that due to a massive stroke cutting his tinkering days short 😔 good to know it will run with just one bank, tho, drastically cuts down on initial expenses getting her back on the road 😎 my wife's grandfather was the original owner, and it's gonna be her daily driver. One more question, is 5° BTDC going to be the timing with just one bank, or is that just if I add the second bank in? I believe stock timing is 9° BTDC, right?

I recently acquired a 1980 510 wagon from a family member, but need some advice on getting it running again. The radiator went out while driving on the interstate a few years ago, causing a serious overheat and warping the original head. The previous owner couldn't find a single spark plug Z20 head to replace it with, so he used a dual plug Z20 head under the advice that that all he needed to complete the conversion would be a dual plug distributor. I know it will also need a second coil and the related wiring fabbed up, but is there anything else I don't know about that's needed to complete the retrofit? Also, would I just be better off leaving the original single spark ignition intact and just running one bank of spark plugs? Thanks in advance, really want this survivor back on the road!
