yes both 1stand 2nd gen are the 4g63 but there is a little difference in the engines. Haven't heard too much of crankwalk in the first gens. And yes the talon and eclipse are the same also the turbo laser adn gr4 have the same engine
crank walk means that the bearings in the cranks have play... meaning the crank over time can "walk" around and cause headaches, hemorraging, and yes pms tia
