Too many codes

Suprised that it runs, the 2000 2.5 MT has a different crank sender than the automatic does. Your ecm is confused. Slide the cogged wheel off of the crankshaft and switch them, it will end the confusion.

1. reset the codes and see which ones come back first
2. you probably need to swap the crank sprocket and drivers side cam sprocket - they have different trigger marks, but otherwise are identical.
trigger marks are on the back if you want to look for them.
although if it drives maybe you already swapped them?
3. pull main engine connector, clean/inspect, plug it back in and make sure it's fully seated.

Most of it could very well be a ground you forgot to put back. There could also be a plug or two that wasn't plugged in or fell back out or that doesn't transfer from one motor to the other. Most if not all of this can be remedied.
Any time I swap motors I put them side by side and try to make sure everything from the old motor gets swapped over. You'd be surprised how many small differences there can be.
As far as the map/maf, it sounds like the computer is looking for something that isn't there. In which case the codes will probably never go away. I'm guessing you will end up having to swap the ecu.
Did you swap the transmission too?

^Both engines are MAP - not MAF - so ECU shouldn't matter.....IMHO>

I don't know enough in particular about Subaru motors to know, but I know from other vehicles I've swapped, sometimes things don't play well together from one year to the next.
Do these require any re learn procedures?

used my intale from old engine
This should include the harness (I'd hope), w/the change in sprockets, should have been plug and play....EGR on '03? Just need to plug the EGR hole in the driver's side head. The ECU's not looking for it, so won't miss it.
Relearn is behind the scenes...meaning you won't get codes initially. Some systems (EGR, Purge) take a few drive cycles (ignition On>Off>On>etc) to verify, and throw a CEL if something's out of whack.
I'm NOT the 'go to' on the '00+ stuff as much...so no quoting! :-)

There are no wiring harness issues between those two engines.
2. Clear codes and see which come back first.
3. Did you disconnect, check, and reseat the main harness plugs?
4. Was the previous engine running perfectly well immediately before the swap?
Did it sit for a long time?
If so you may have rodent damage to wiring and this isn't swap related.
I've seen so many Subarus with multiple disconnected ground straps, I'm not sure when and how it matters but it's not commonly a huge issue.
I'd like to know which ones actually cause issues. That might make it easier to focus and track down.

1100 is for the starter switch circuit
1101 is for the neutral switch.
P0500 Speed sensor
131,132,136 O2 sensors
All have connectors and wiring on top of the trans. If the trans was jacked up and pinched against the bottom of the firewall tunnel the wiring could be pinched or cut.
The TPS code could just be due to misadjusted TPS. Maybe got knocked around when the intake was being installed.
Knock sensor is under the manifold, easy to miss when plugging everything in. Make sure it's plugged in, replace it if it's old or the plastic housing is cracked.
