Hey guys i was wondering what is all needed if i want to do this conversion obviously i need a gsr and the itr cams?? Do i need the ITR ECU as well. What kind of performance can i see from this mod. Also is it worth it? What are some better mods that i can do. Also what type of gas mileage should i see if it is in an EK hatch??

Thank you in advance
