EG33

From Wikipedia: The EG engine was a direct replacement for the ER found in the Subaru XT sports car. Replacing it was the Subaru Alcyone SVX so Subaru needed a new engine. As with the ER27, Subaru took the EJ22 and stretched it two cylinders to make the new EG33. However, this four valve per cylinder engine was DOHC and used many valvetrain parts from the not yet released EJ25D.

Usage:
* EG33: 3318cc DOHC, 230hp@5400 used in the 1992-1997 Subaru Alcyone SVX

If you're interested in a 6-cylinder Subaru, the best choice is the EG33. They are fairly common and easy to obtain, however, not as many aftermarket parts exist for this engine as the 2.5L motor. The 3.3 is not recommended for boost levels above 5 psi. in stock form, if you want it to remain reliable and maintain longevity. This is a great engine for naturally aspirated applications running pump gas tuned to 270hp. It also utilizes the same adapter kit as the 2.5L engine. Header kits, wiring harneses and engine computers are also available to boost power on this 6-cylinder.

EZ

Instead of stretching their current EJ20 as most might suspect, in 2000 Subaru did this family from the ground up. It is a totally new DOHC design using dual timing chains and coil-on-plug ignition. Nothing from these engines are interchangeable with any other Subaru engine as in the past. The EZ36 was introduced in 2008 to help the Tribeca's sluggish performance. It is a bored and stroked version of the EZ30.
