I have a wrecked 2013 honda civic si non repairable...... Engine and transmission is still running strong an i have a honda civic si 2007 an recently my motor took a **** (not sure what took a **** if it was my bottom end or my top end) will i be able to swap the k24z7 to my 07 civic si an what exactly will i need to do the swap im not i was just gonna go an get a k20a but since i have the 2013 will it be possible or ?

Not compatible. The K24Z engines are quite different from the rest of the K-series.

What about a k20/k24 swap if my head on my k20 isnt damaged ?

Do you mean K20A head on K24Z block? Again, not super compatible. Lots of modification needed to make work. If you’re meaning a K20A/Z head on a K24A block, that’s fine.

For the sake of ease, I’d just swap in a new K20A engine.
