From reading posts on this wonderful website... I now HAVE to do the swap.. My question is whats the difference between the lq9 and the lq4? I think i found a great deal on a 02 lq4 motor and tranny for $1600 with 60k on it. Is that a good starting point? Whenever i swap the engines around who can reprogram my cpu? thanks for any advice you guys can give me!!
