2003 2.5RS Impreza engine into a Baja?

[Takaaco]

Im looking for a new engine for my Baja, and a salvage yard has a 2003 2.5 RS from an Impreza. both are non turbo just wondering if its a direct replacement or do i need to swap ECU's or anything? Or if anyone has an EJ25 laying around let me know.

Somebody on the Baja Facebook page send me this:

Flat four EJ251
The EJ251 has demonstrated externally leaking head gasket issues on occasion as the engine accumulates mileage over 100,000 miles (160,000 km). SOHC Intake volume is calculated by the use of a MAP sensor, unlike the EJ253 which uses a MAF sensor. Compression ratio is 10.0:1.
Power ISO: 123 kW (165 hp) @ 5600 RPM
226 N·m (167 ft·lbf) @ 4000 rpm
Usage:
Impreza 2.5RS, 2.5TS 00-04 (US)
Impreza Outback Sport 02-04 (US)
Forester 00-04 (US)
Legacy 00-04 (US)
Outback 00-04 (US)
Baja 03-05 (US)

So yep they are interchangeable
