I am looking deeply into swapping my Ej25 for an Ej20 (hoping Im even saying that correctly). Basicly I just want to know if I can bolt up an sti transmission to my 2.5 rs engine. Iv read they bolt up and Iv read that I would need to also swap my rear diff and hubs and axels. Im currantly working at Buffalo wild wings so not making huge bucks but only while Im going to school. No big bills to pay and I want to start swapping for stuff to do in spare time, but again Im not making the big bucks right now. is it even worth it to start now or should I wait untill I go to work at this dealership I have lined up for the summer. So, I guess the real question is how smoothly can I expect it to go if I just want to change the tranny and clutch (clutch needs to be changed its still original 2005 clutch)?
