it depends on what you're using it for but, in mechanical aspects you have 55mm main journals rather than 50 and full floating wrist pins, yay for you

 

in my own experiences maybe its just my motor..i really want a JDM h22a cause of the high compression and specs...but since ive gone against built ones (14.5s) with my stock motor H22a4 and taken some out im pretty good with my motor i guess but i still want an JDM motor. I lost to one that had cams slicks etc..on my stock motor by two cars due to of course no traction and a slipping/blown/destroyed clutch...and he only did a (14.9s) but then again i still want a JDM motor..

 

Stock for Stock the JDM H22A will WIN every time! They consistently make 5tq more on the dyno and the compression makes running a more agressive cam easier to reach. 2 layer head gasket and Flat valves gets you about 11:1 from a JDM motor.
