1987 Honda Civic Si
Generation: 4th Gen
Engine Code: 1.5L D15A3
Chassis Code: EC3
I have a 1987 Honda Civic Si with 1.5L SOHC PGM-Fi engine. It’s a 4th gen vehicle (EC3) with a D15A3 engine. The engine is a third generation one since it’s an upgrade of the D15A2 engine. I’m not sure where to go with this as I’m confused with the two different generations: one for the chassis code and the other for the engine. Can anyone here help me understand this please?
