I love my hybrid set up, and a question I have is the pertaining to the scavenging ability of the 2.0L heads w/ported block matching the EJ257. The 2.0L cams seem like they won't do an adequate job of scavenging the exhaust gases from the combustion chamber. Leaving a lethal combination for those that start to run bigger turbo set ups. Some use a header set up allow more flow for this. However, I don't know if it's the correct logic, but on top of matching the heads relative B25 combustion chamber, wouldn't a set of cams and a good valve angle job to work in concert with the chamber being opened up be more beneficial for engine health/efficiency and ...well power too?
