The way I look at it is. Why take the two ************tiest parts of the motors and put them together for a giant ************ty motor?
Yea you gain more power from the compression. But the 2.5 bottom end sucks and the 2.2 heads suck just as bad.
If anything I will go with a full on 2.5. Figured hell, why not make the 2.2 a little more torquey. But everyone is advising against everything with them.
I suppose I will stick to the Hybrid intake and Exhaust. Until I move on to something bigger and better.
