Hi, I'd like to know what engine is required for my 1991 Honda Accord lx? It's not starting at all and my engine is flooded with water so I need a new engine to put in but I am unsure what model and type of engine fits for my vehicle. Please help!

The engine no. is on the engine block, just to the left of the exhaust manifold. Be sure to get an exact match, otherwise the ECM, wiring harness, and sensors won't work properly. Keep it simple.

Is it possible that I can put an engine from an newer model honda accord lx into my 90 one?

Many try and many fail.
