Hawk to hatch engine swap
 

Hi all
im looking to put a forged 2006 sti hawkeye engine/longblock into a 2010 hatch wrx s, are they the same or any major differences, hawk heads are b25 single avcs

If the wrx s is dual avc's then you'll need an aftermarket ecu.

Cheers mate, never did find out and have abandoned the idea as the guy wants too much money for the hatch with the blown engine
