Is there a difference between the H22 engine that came with manual and automatic tranny ?

the longblock is the same for auto or manual with the jdm engines.

the h22a originally equiped with an automatic has less HP than a original manual engine

Can you tell the difference just by looking at the engine ? Intake manifold ??

i'm not sure but the engine horsepower rating should be the same. And the only reason people think its less horsepower with an auto is because you loose more horsepower thru the auto tranny with a torque converter. regardless if the engine is auto or manual it should be the same horsepower, its with the tranny you are using. if i'm wrong somebody please correct me on this

an automatic jmd h22a is exactly the same engine as the manual.

Correct. We've torn them down before, and the pistons, manifolds, and the cams are the same. Everything else (assumed, since there isn't anything else to change for a power decrease) is the same and same part & numbers.
