I've just spent a laborious x minutes searching for the actual differences between h22a2 and h22a5. Can't find them! Are there any internal differences?

Does it not make a difference if you just want to plug it straight into a chassis though?

only if you keep the engine harness that comes with the engine instead of using the harness that comes with the car

Hi all,

was you able to swap a H22A2 by a H22A5 ?
Is there any complication ?
