ok, if you have a GS and want to have a LSVTEC with your stock ECU, and you dont know you can make a LSVTEC with the engine in your GS. you CANNOT do it yourself, PERIOD. yopu at least gotta know what you are doing in your mind before you do it in real life, and you got no clue, read about LSVTEC by doing a search for LSVTEC and then when you know whats going on with the swap ask some smart questions, cuz remember, no such thing as stupid questions, just stupid people.
