In looking around for a LQ9 I am finding out a few things. First the LQ9 is somewhat hard to find used and when you do find one of them the prices seem a little high. During my looking I have found quite a few LQ4s and they are priced very reasonable. From my investigation the major differences I have seen between the two is that the LQ9 has about 20 more horsepower and a little higher compression.
I light of this is there any reason as to why I wouldn't use the LQ4 over the LQ9?
Is there any other reasons that you know of as to why I wouldn't want to use the LQ4?
