What is firing order on ea-81T?


Recommended Posts

I'd be willing to bet that all 4cyl Subarus (boxers) have the same firing order. I worked it out one time, and there are only two physically possible firing orders for a horizontally opposed 4 cylinder engine:

1-3-2-4 and its reverse 1-4-2-3.

 

Anything else would require all of the pistons to move the same direction at the same time, and that would NOT make for a very smooth engine!!
