Well apparently the freaking pistons melted or something. I didn't feel a thing when it happened so I have no clue. So now I am screwed if anyone knows where I can find an used motor please let me know. Also do any otherr motors fit in a prelude. I know the h22a4's are hard to come by and also has anyone heard of this company http://www.rpmmachine.com/enginetophonda.html cause if the head is ok which I am waiting to hear about the I can get the bottom end for 775 plus shipping.
