Get an Si

 

What he said ^ it'll cost you more than just buys by an si

 

If you can snag a k24 swap for a cheap price and have lots of money, expertise and time - go for it!
Ive personally never seen this done

Cost and effort probably not worth it. So much can go wrong it isn't worth the headache. Head swap in itself is not easy to do properly and now your also converting to an Auto transmission which isn't even geared to that engine and that's probably just the beginning of it.

 

LS swap it.

I plan on doing a k24 swap with a k20 head with full bolt ons and a tune.
My car is a 2012 Honda civic ex sedan with the r18z1 engine Auto.
Does anyone know if it can be done, how much it could cost, and any suggestions in general on this swap?

Just about ANYTHING can be done if you want to spend the money.
Nothing more to see here. Next!

 

I tell that to customers all the time. With enough time and money anything is possible.
