Step 1:
Find alternate transportation.
Check!
2013 Civic Si 2.4L NA M6. 221,000 miles, but the engine only has ~100k on it. It has an Acuity intake and shifter, and coilovers.
It came with a Hondata tuner, and I had to retune it to get it to set the emission monitors so I can go be legal. Fueling was way off with a MAP tune (like +50% LTFTs!) and the rear O2 was turned off, too. I started with a stock tune and did a MAF tune instead of a MAP tune. So, as an added side benefit, now I have some familiarity with Honda ECU's and Hondata software. LOL!
I bought it with the intent of selling it after the ZL1 is finished. The problem is I really like it so far, so I'll probably keep it and drive it on the rainy days instead of the ZL1. I never thought I'd say that about a 4-banger, like... ever.
Oh well. Cars and car guys. Whatcha gunna do??
