Head Swaps 4AGE to 4AGE

[JayB23]

Has anyone in here placed a 4AGE head onto a 4AFE? Any info???? I heard it is possible, but i don't know the procedure.

I think the bolt holes/ oil/ water passages dont line up properly. Check out http://www.club4ag.com/ for more info. Also, dont forget you'll need to change the ECU and wiring harness (big money).

Hmm...I heard that too, I'm wandering, if I stick the throttle body of a 4a-ge or a 7a-fe onto the 4a-fe, will it affect my fuel to air ratio too much?? Or will I actually have a performance gain due to the airflow increase???
