It's timing. Not timming.

And 2j negatives? It came in a different make of car? For someone who thinks setting timing and wiring on a KA is difficult, you don't need to be swapping engines from another Nissan car, much less another manufacturer.

Bring your "fairly decent sum of money" to a shop and let them build a nice SR20 for you. There's absolutely nothing wrong with an SR. Quit trying to be different, you're just like everyone else. There is nothing new you can accomplish with an S13.
