Default 4th gen F22a1 to F20b help please

Hey guys. Been a while. Quit my job last week and it’s time to get my backup Lude running. Grabbed a fresh F20b (auto) to swap in. Car is SOHC f22a1 stock. OEM engine harness is in decent shape donor motor only came w a few plugs.

The plan is to run this motor w the original harness, trans (manual) with a chipped and tuned p28

Questions/problems
1) Injectors. I have OEM f22a1 OBD1 injectors and donor F20b obd2 injectors. Will either set work or should I get something else

2) Dizzy and dizzy wiring. Tuner says he only needs ETC, IAT, distributor wiring, injectors and VSS, if that’s accurate what dizzy should I use? Will the F22a1 mount up to the F20b or do I need a H22 obd1 dizzy? Is there a better or simpler option? Does the Rywire harness help me?<I don’t think so because the OEM dizzy is an 8 pin and there is no crank position sensor on the timing side or anywhere else that I have found.

3) Intake. Currently have a H22a4 intake manifold mocked up. Already switched the thermostat housing too. Want to delete as much emissions crap and other clutter as possible. What all can I cap off and what do I need to make sure to keep

Ive got a driver’s motor mount to use and I’m good w wiring modifications. Just need someone to narrow down my options some so I can move forward. We will likely leave the knock sensor on the F20b unhooked because it’s unneeded and I’m not sure the obd1 ECU has a spot for it anyway.
