Regarding the engine, minor changes for the oil sender, if you are using a JDM, normally the oil sender unit is on our driver side. You will need remove the oil sender and plug that acess hole and move the sender to the passenger side, and on to the TT oil tree.
If you are using the JDM engine with the JDMdownpipes, your 2+2 exhaust set up should bolt up to your current exhaust configuration.
