What's the difference between Honda F23A and F23Z4 engines?

I have a Honda Odyssey but the engine is total so I got a F23A engine but it comes with the F23Z4, so I wondering if the F23A engine can work?

I guess not. The F23A came from older Accord and you have not say but the later Odysseys were 3.5 V6's, so I don't know how easy an inline 4 would mount up. Maybe a mount kit exists… Doubtful though unless an Accord mount set up would work.

Anything can be done with a cutter and welder. But just because you can doesn't mean you should. Still, you're better off just throwing an Accord V6 (assuming that works too) than going down to a 4 banger I think.

In other hand, you've mentioned the F23Z4 is another four banger for Odyssey with a 2.3L engine.
