Update on the conversion, installed the new packs and spliced out the existing igniter. Pretty simple job, however, wiring does make me a little stressed. Had some hiccups during the cleanup portion as my turbo timer was causing the car to do weird things (operating without the keys installed; had to stall out the car to get it to turn off so I could trouble shoot). I'm assuming at least, once I disconnected it, the car ran fine and I haven't had issues since.
Would highly recommend this mod for EJ20G owners. Simple, parts are readily available, and it feels like the car runs better then it ever has. You could attribute at to cracked coil packs bringing me down the entire time.
