    Phase 1 or phase 2

    How do I tell if my motor is a phase 1 or phase 2?

    Which motor are you talking about. Do you have a pic?
    If its your signature the dual cam ej25d is phase 1. 99 25d have a phase 2 shortblock but the heads/wiring its still phase 1
    My 98 came with phase 2 shortblock but who knows, maybe the previous owner had it replaced

    I don't have a picture now, sorry. I do know it's a DOHC EJ25, everything seems to be original/stock.
    What is phase 1 and 2? Are there differences between the 2?
    I was going through some forums and stumbled upon this, is this true?

    all ej25D (dual cam) are phase 1 (found on 96-99 legacy and 98 forester/impreza rs)

    and the rest of the dual cam ej25 after that are from the turbo models (04 forester xt up, 05 legacy 2.5gt up. 06 wrx up, sti's....... )

    phase 2 2.5 non turbo are single cam (00+ legacy, 99+ impreza, 99+ forester....)
