Rods, crank and block should to be checked by an expert for damage before reusing them. That should be your first confirmation. If no good, OEM short blocks are about $2,000 with tax.

You can get any parts - including shortblocks - from BuiltEJ: BuiltEJ

I'm planning an OEM rebuild of my WRX EJ205 at this time.

^ What he said. If...and if some how they aren't damaged. You'd have to tank everything to get any and all little shavings from the bearings out of the engine. What good is it? If you pass some shaving through the oil system? Cranks are known to be thrown out of spec and warp with spun bearings.

The crank throw bearing surfaces look marred in one of those photos, which will affect bearing clearances and likely spin bearings again if not corrected before assembly.

I'd replace the oil cooler as well, as it collects debris and can deliver it back into the oil once rebuilt.

The oil cooler is the assembly the oil filter screws into.

H-Beams are fine for anything the stock rods would hold. If your power goals are high, you should opt for i-beams.

2008 WRX has slightly different compression pistons and completely different heads than the 2008 STI.
