Thanks.
I have to say I am puzzled. Have been searching for quite a while now.
Managed to set that:
This motor was used in Legacy and Impreza SRX
Depending on year and transmission it develops 180-190hp
Has AVCS and 11.5:1 CR
You can find cars with that lump in Japan, Russia, New Zeland (not sure where else, but I don\'t know Japanese nor Russian)
I tried Wiki, TradeCarView, GooExchange, found links to JDM brochures here somewhere
Wiki and local dealer aren\'t really usefull.
What seems to be a fact.
EJ204 (MT) revs up to 7100, is 190hp and 200Nm, DOHC, AVCS
What I thought it is
Dual AVCS, WRX internals
What I suspect
Different inlet manifold, ECU, head or piston design
