Car started out with 2.0 that was fairly well built. Larger injectors, ignition, etc. Apparently one day the air filter fell off. So Jeff C. (Guy I bought it from) bought a 2.5 from Outfront. He kept the 2.0 turbo on it after being rebuilt so it is technically a little small for this motor. Suits my driving just fine. No lag and that was my big gripe on the other one. Too long to spool up. This one just pulls hard. But for the noises of the turbo such as BOV etc you would not really be able to tell it was a turbo motor.
