Default clearing up ej22 to ej25 swap

I got a ej25 out of a 2000 legacy that spun the main bearings and would like to put the engine into my 95 legacy w/ ej22. Can I use my flywheel? My intake manifold? Will these bearings http://www.tweakit.net/shop/product_...09j07obd547hi1 bearings work?
Im going to use the 2.5 sohc heads and get the cam regrind from Delta.

was the EJ22 DOHC? If so, you will have an ECU problem to figure out too. and I think you could use the EJ22 heads on the EJ25 shortblock to get a nice compression bump. will need 91oct though.

No the ej22 is also sohc. i thought bout the frankenstien build but i dont wanna deal with higher octane. Another question: Will my stock dual port 22 headers work with the 25 dual port heads?

they should bolt up fine. keep in mind you have more displacement so the 2.2l headers might not be optimal for the 2.5l. being a 0.3l change probably makes it a non-issue, though.

The exhaust manifolds for all the NA motors are the same. You should have no problems. I would use the injectors from the 2.5 if they are side feeds though. Maybe the FPR too just so you don't chance running lean in the upper rpms.

not quite correct. there are single port and dual port and where the flange to connect to the rest of the exhaust is varies greatly depending on year. In your application they will work fine.

You may need to use the engine harness from the 95. The swap is very straight forward though. Which grind are you looking at? Your flywheel will work. The header will work if the head exhaust ports are the same.(dual port to dual port. The '95 should have a dual port.) Use your intake and the MAF from the '95 for wiring ease. You can add a delete plate or just do not plug it in(there won't be a lead if you use your harness). The bearing should be fine. Have you checked the crank yet? You need to verify that it is usable/turnable before you order bearings.

Good luck with your build.
