Default New Style STi 2.5 Motor 2011/13

Hey Guys

I would like to know if the new STi 2.5 short motor you find in the 2011 to 2013 series. Will a set of Version 6 heads bolt straight up to this? Also would this bottom end be considered stronger than the Version 7 STi EJ207? If so,

Is there any advantages to running the 2.5 ltr short motor over the 2ltr?


Cheers

No the 2.5's are weaker.

Ej207 is far stronger and more reliable.
