Thread: Difference between ve-heads casting-wise

Hi,

somewhere here around i read that the P12 head has an advanced-cooling-ability. The combustion-chamber seems to be better water-cooled. So the
p12 head seems to be the better choice for a boosted-drift-engine where the engine suffers permanent-high loads. My question now is:
- Is there any difference between P12 and xtrail-head concerning cooling and airflow. (Independently from cams and valves)
- does the p12 flow better than the p11 or do both have the same sized channels. ( i am not sure if channels is the right expression, but i hope you know what i mean)

The P12 Primera 20v and the Xtrail GT sr20vet both use the same 8H6 head casting and are identical from what i know. This is the better head for cooling and detonation resistance, it is just harder to get and also higher to repair and replace the parts when needed.
