Not quite sure of your plan, but USDM WRX wiring and ECU will not control an early EJ20G. You should be able swap the cylinder heads and intake manifold and the crank sensor to the older motor. Basically just use the shortblock, but double check compression ratios and head gasket thickness to be sure.
Ok, that blows... I won't be able to fabricate anything for now, so I won't be able to go that route. I do like the idea of just using the ej20g block, but we'll see. Thanks!

Yes I'm aware of this. The engine I was looking at did come with an ECU. I think I'm just going to stay USDM for now.
