Engine replacement options

Gen 4 is very close.

This is swapping a 4th gen into a v, but same as swap into 3rd gen. Epic video saga by @Ragingfit :

He retains the third gen intake/exhaust manifolds, throttle body, and EGR components.

And a couple of threads by @cnc97:

Similar to above, but he retains also the third gen cylinder head.

There's another guy here, @Sandog53 , who's in the midst of a swap, similar to @Ragingfit but also attempting to use fourth gen intake manifold, throttle body and EGR components. He bent the 3rd gen exhaust manifold to EGR pipe to accomodate 4th gen EGR cooler location. He might actually be wrapped up. He's posting in the last few pages of the first link above.

Looks like this link doeasn't work so just type in car-part.com and you can look it up....there are plenty available but they aren't cheap!

 

What’s wrong with your engine you need a swap? If your heads are good, you can get a brand new short block assembly for under $2k. I believe it comes with the updated pistons and rings too (but don’t quote me on it, ask a dealer to verify)

I also have completed the swap, using the gen4 egr and intake. It's in the gen3 technical discussion, not sure how to link it though.
