id say not counting the ones on the manifold there are maybe under 6 sensors on the blocks and head

wow i just checked the parts diagram, youll need to change, the Crank position sensor, the cam position sensor and the knock sensor
if the ones you got on the blown engine are good and you want to be cheap its free, dealer MSRP for all three is about 300 bucks, but of course you can get them online for 200ish all together.

The only reason why i am saying they are not comparable is because they have different part numbers. With the new ECU they could be sending out different values to the ECU and if you dont switch them it very well could not run at all.

Since the basic block design didnt really change you just unbolt the old ones and swap them out.

hope this helps you

Also might want to swap the timing components, like I mentioned above, such as the crank and cam gears because they might have different pickups.

I really appreciate everyone's input on this. I'm debating to whether or not using this 2.5 engine or just going with a 02-03 wrx engine swap. I know both will be a good amount of work.

The wrx swap is CONSIDERABLY more work. Honestly, sticking with the 2.5 will be alot easier than you imagine. I had never pulled an engine on a vehicle before and I found out how easy it was on my 2000 Forester this past summer. If you have the right tools, you could easily pull your current engine, swap over your intake manifold, sensors, etc. and reinstall in the car in a weekend. Especially if you don't have to change the headgaskets, get the heads milled, etc.
