I just blew my engine on my S4 vert and I was thinking about going into a TII swap. My question is what are the major things I have to get to make the swap successful and clean. Is there going to be a problem if I get a S5 TII jdm engine and install in the S4. What are the problems will I encounter and what other parts do I have to get to make everything compatible. I appreciate your input.

 

Read the FAQ for the massive amount of turbo swapping detail they contain. There are multiple writeups.

Sick with your series unless you are installing a full standalone.
