In the cylinder head exhaust ports. It did not come with the manifold like the picture showed.
Unfortunately, I am using my 2.3 intake manifold, though the 2.5 looks like it could work, it has a bad vacuum actuator on it and I can't find one anywhere except the dealer... the attachment for it is located on the top instead of the bottom, as is on the 2.3. Same attachement though. There may be issues with the connector reaching up. Other than that, all the sensors are exactly the same on both engines. Same numbers on them. The egr valve may be different (there were some cars made in 2010 with a different EGR valve), so I swapped that. They look identical though.
Also, the front cover is the same. There is a slightly different angle for the motor mount, which is probably there to solve the mount issues people were having. It looks like a more level angle which seems to put less stress on the mount. I could be wrong, but that is the only change on the front cover and I do not think they did it for no reason.
The engine oil in the engine I received was black. It was starting to sludge in side. I knew there was a reason it was cheap and this was it. It seems the owner followed the 15k oil change rule that the dealers are telling them. Soooo many cars out there now with this issue and failing sticking actuators. I replaced the solenoid and tried to swap the actuator with the one I bought for the 2.3 and the sprocket is different. The 2.5 chain is bigger and beefier. I put the old actuator in and will hopefully be able to clean it out with some engine flushing. If not I will replace it. Lesson learned, money saved could have been put towards an engine that was in better shape. I just jumped on this buy early in the morning after drinking a few beers. Figured $380 I could part it out... I decided to use it since the plugs look good and the compression is great. We will see. Most likely I will be pulling it apart again to replace the actuator.
