Hello Everyone, 86 accord dx

Hey, new to here so just wanted to say hi. I have a 1986 accord DX I just bought for my wife for her birthday. It was her very first car she ever owned and she's always talked about it throughout the years about how much she loved this car. Well the car is carb and I have a b18b jdm with a manual trans a friend gave me. He also gave me the ecu, wiring harness, engine mounts, shift link, both axles, and a few other items. I'm doing the swap little by little due to I don't have a clue how to go from carb to fi. I have replaced engines before but of the same kind. Never in this spectrum. Hopefully here I'll be able to finish my wife's favorite car.
