Default 2.5 swap into my wrx

Hey guys finished up i 2.5 swap in my car and the motor is loud as hell.
i got forged pistons and rods and that but i was expected the motor to be this loud. It runs good has good oil pressure and egts are also good. And the heads are ported and polished. But the damn thing sounds like it has piston slap or something. Is this normal or should it sound like the old 2 litre did

I agree though....the engine shouldnt sound like that....I would have that re-checked by the people that built your motor.

the ej257 w/ ported heads (shortblock from Subaru) in my junk sounds the same as the ultra crap 2.0, but the idle doesn't drop as much when the a/c kicks on.. woo hoo.

If it is REALLY loud perhaps it was assembled improperly.

If it is just louder than your WRX, well that is normal.
