EJ255 is WRX EJ257 is STI.
257 is not a JDM Impreza engine as far as I know.
2.5 litre in Japan is an unusual insurance class and is not a popular engine size as a consequence. That is why JDM Impreza STI cars are 2.0.

I know, from the outside, the ONLY way of determining a CDB is the x-hatch around the oil filter housing - as it's unique to a CDB. (So I'm assuming a ODB has NO x-hatching anywhere on it?)
What about a SCDB though - how do you determine one of those from the outside?

Ummm thats interesting because the article i posted says the blocks from the ej255 and 257 are the same, the differance in the two being the PISTONS and some head components.

As David said, EJ255 is ODB and EJ257 is SCDB

The 2 litre hatch JDM block is a W spec and has monster sized liners fitted into the SCDB. We use that when we cannot get old style CDB's which are running out and will be extinct soon. Bloody global warming !! - everything else gets blamed on global warming, why no the extinction of CDB's ??
