a 2.5 long block is a wiring challenge

apart from forced induction the 2.5l short block 2.2l head combo is the most cost efficient way to make more power

op get a NA 2.5L (doesn't matter what year just as long as it's an ej series) and bolt your 2.2L heads to it, run 89 octane and be done with it
