Some useful info since a lot of members have these engines.

EJ20X uses the VF38 turbo and makes 260BHP in the auto versions.
EJ20Y uses a TD04 turbo and makes 280BHP in the MT version.

These engines sound like they are tuned for fast and response and low down torque compared to previous versions (eg. twin turbo EJ206 and EJ208).
