ohh goodness, ive thought about the 4bt swap, the 12 valve swap, and even a common rail swap, in all reality the 12 valve will probably what we do if we can find one, there arent many 4bts around here, and common rails are expensive, they all will be a manual, and the best part is the 12 valve has so much more of a backing (that i can find) then the 4bt.
