Swapped tranny and rear diff in my 2003 Baja (EJ25) a couple years back. Installed a 5 speed from a 2003 WRX (EJ20). Also installed a lightweight flywheel.

 

Clutch disintegrated on the highway thus week so the tranny is out again. Found the flywheel and pressure plate badly roasted. Flywheel was blue and warped like a potato chip. I'm ditching the flywheel and replacing with one from a 2003 Impreza (EJ25).

 

Removed that flywheel without checking position of a timing mark. How do I time this replacement? What, if anything, is the correct alignment?

there is no timing on any ej series engine, put it on and have fun

That's a relief since I didn't mark it. Thanks!
