This thread has been something needed around here for sometime. I guess I should throw in some of the info I have been sitting on for quite awhile. If you are REALLY motivated and want to see about possibly using parts from a different engine to make more power you will need to know how and what the measurements are for the Justy engine. I'.m too dam lazy to type all the info out so go here for the story on how the info in this picture is found and used. : classicsubarujusty.proboards.com/thread/326/justy-engine-specs-measurements

My post may not fit this theme perfectly but... I get these torque specs for Dustys Justys some time ago... I had some problems with translating it (now I might hit maybe half of them)... I think there is more people around the world who doesn't understand what bolts are on the list... In schools outside english speaking countries you didn't get education about "tech-english"... I think it will be good thing if We put it together with the parts look up blueprints. (Don't worry I have them downloaded too)

Anybody have dimensions on the balancing shaft bearings? or better yet a source?
