I was just wondering what the differences were between the LS,GSR, and Type R compared to The US ones. Im assuming that the LS was made in Japan too. I honestly don't know. Anyways, I guess i could research a lil more but im lazy and couldn't find much. Also, I'd like to know what makes the JSpec engines more powerful. Less restriction, OBD2 BS, or whatever. Just hook a brotha noobie up. Thanks in advance.
