    You don't mention the third digit in the engine code of the new motor but I assume it's a turbo motor. If you didn't get the injectors, you need those, and you'll need to map the new motor because your current ECU is trying to fuel a 2,0L. Did you carry over the intake manifold, and is the new motor set up for drive by wire and/or variable valve timing? You need to sort all that out too and see what's there, what you want there, and what you can control.

If you are none of these you can be sure it will kill you too but there will be no special hurry. Ernest Hemingway, A Farewell to Arms, 1929

    So you're saying you put an EJ25 (which one?) into a car that used to have an EJ20 in it? So which car was that?

    On top of that...what else did you swap?

    Come on man, we need serious information if you really want help. You give us no details to go off of here. Like literally...no details.

    What kind of car do you have?

    What parts does it have in it? What short block, heads, etc.? What wiring harness and ECU are you using? What injectors and fuel pump? Is it drive by wire, or drive by cable? Who is tuning it?
