2.3 head differences?

[VEGAS]

why are people insisting you need the 2.3L intake? my 2007 focus 2.0L motor died, replaced motor with 2.3L and installed the 2.0L intake no problem..

I don't know. Probably cause they think a 23 head has to have the 23 i/m. It does the job, but the 23 i/m does it better.

i know for a fact it works, and I feel the huge difference in power with 2.3L engine compared to 2.0L even while using the 2.0L intake.

Maybe I will see a huge gain when I add the cozzy knockoff

i contacted a guy, he said head is same head, just valves cut larger on 2.3L

so the ports aren't even bigger? that's why I'd assume the 23 IM is required... to get the most benefit from enlarged ports for a higher cfm.

how much does it drop the CR if you don't mill the head?

Ports a little bigger, but the head over all is same..
it will bolt up just like the 2.0L


I mention this so if you need to use the 2.0L as a CORE they will accept it

nice

the intake ports are tiny bit larger ( might no even notice it with the eye) but the 2.0L will bolt up with no issues.

so it should be no problem to run a 20 im and not necessary to run the 23 im

Doesn't the 2.3 NOT have that CHT sensor?
