How's it goin'? Got a 95 impreza wagon and the #2 spark plug keeps blowing out of the head. should i buy new heads or go with a 2.5 swap? found a motor from a 98 outback w/ the 2.5. How difficult to swap. i heard somewhere that all the 1.8 stuff( computer and harness, with some splicing) will work being that its a series1 2.5.
