This past weekend I broke down and had the engine replaced in my 98 OBW and the proccess was quite interesting. Turned out it had a cracked head and burnt valves.
My certified Subie mechanic took a second gen block, slapped on first gen DOC heads and canabalized parts from a few other 2.5's in the garage. Added electricity and SHE LIVES!!!! And runs better now than she did the first time I brought her back to life.
He had mentioned a few weeks before that he had found out that the head of the 1Gen fit the 2Gen block and said it gave more power.
Anyone here done this and have more details on performance of such an engine?
