The following is what I ordered from Inyo pools:

Will the existing diffuser not work with the new kit?
If I rebuild the old motor, it will be for fun, and not be put back in the service of the pool. Can these motors be repurposed?
Everything came in today. While waiting, I decided to clean the DE filter since it was time. I also re-lubed the diverter valves.
The old diffuser has the part number on it, and it's the correct one. The new one is obviously correct, but has no identification stamp.
The old impeller has no stamp, but looks nearly exactly like the new one (which would be wrong for the old motor, right?).
I went ahead and used all the new parts, and got the motor set up. Tomorrow I will install it. I'll also add pics.
Of note: the thick (bonding?) wire that attaches to the outside of the motor was not attached. What are the consequences of that? The existing wire isn't long enough to reach where the motor will be (maybe that's why they didn't attach it?). Can I splice a length to it?
I searched all through the NEC code one time to find the answer to this question. Couldn't find it so I decided to take the safest approach and use a new wire back to the old connection for the old motor. I would run a new bonding wire back to the point where the previous wire connected. If it was spliced to another wire be sure to use a proper new bonding splice connector. You can get these at big box stores in the electrical department. Use the same size wire as the rest of your bonding wire. For most residential pools this is #8 copper. There are a couple of different brands of connectors and Morris is common. Allen seems to know a lot about code requirements, maybe he can help. @ajw22 can you help?
I looked at the wifi link they sell and my take is it's not worth it. Almost $300 for a simple wifi that adds features I would never need even if I didn't have automation. Once you set the internal schedule it runs daily. If you really do want to start stop remotely a neat DIY alternative is just get a 3 HP pump start relay and trigger it with a cheap wifi switch board. Pump start relays are under $75 and wifi switch boards are under $20. Krain makes a nice switch with an outdoor housing.
Another neat feature the 2.7 hp v-drive has out of the box is an aux power supply that can be used for swg. My 1.65 has a superb digital input interface not available on the 2.7 but it lacks the aux power connector.
