t5 trans swap?

ive done a little bit of research on the T5 itself, and it seems that im going to need to upgrade it a bit in order for it to handle the power of the 340 (even though my 340 is going to be very mild). I think the most clarification i need though is what is actually involved in performing the swap into the mopars so i will have to message american powertrain and gmachinedart and talk to them i guess
