Only notable things were 1.Had to swap dizzy from Y7 to 16A because harness plug was different and would not plug in. Remove the 3 bolts holding it in, pull straight out. Notice the drive lugs are slightly off center, re install with correct orientation in new motor. 2.Had to do the CKF bypass trick as the D16A does not have a crank fluctuation sensor. I was able to do the "option 1" bypass without cutting any wires. Over 750 miles now and no CEL. Here is the link for bypass trick. .:FFS TechNet:.

Inspect yours carefully and repair before you install in the car. 4.If you have to swap the oil pan, you MUST get a new gasket, or else you get a nice pinstripe in your driveway like me. That's all I can think of for the moment. Thanks to Theo at Gold Autos in Rialto, Ca.
