ej25 good upgrade?
I'm looking at upgrading the ej20 in my classic uk impreza soon as I want to take the performance a little further, i'm currently running 330 bhp 300lbft @ 1.35bar, I'd like to achieve between 350-400 bhp/lbft with minimal lag. I am aware i'll need the supporting mods but am not sure weather to use an uprated stronger ej20 0r go for ej25 as the basis of the upgrade? have seen an ej25 advertised and wondered if this would be a good basis and how it was different from the new age ej257? Thanks, Neil.

Any thoughts, idea's people? would like to know what would be a good basis for an upgrade? would a strengthened ej20 be suitable? or is the 2.5 route a better bet? thanks in advance for any help /suggestions.

Isn't the EJ25 open deck and naturally aspirated? If so then you'll need to change the pistons to lower the compression ratio.
