DO NOT , whatever you do , tell them you have a 3.0 motor in there !!!!!!! YOU WILL NOT PASS , even with no codes ! By the letter of the law , the car cannot have a different engine in there that it didn't come with at the factory . Even with the '74-'84 test it must have the correct engine in there .



Actually, that's not true. I asked the state DEP about that when I had my engine done. Their answer: "You have to pass the more stringent of the two tests, if the motors have different limits."

Essentially, unless you use a 95 2.5L OR a MY04 3.0 or newer, it doesn't matter. The standards changed in 96, and are changing again for 2004, but the 96-03 2.5 and 3.0 Duratecs use the same limits. (This only applies for PA.) The DEP quoted a specific code that was written exactly to deal with hybrid engines, like the one I have. I might have the email *somewhere*, but it's been over 2 years since I asked IIRC.

Then again, it doesn't matter if you live in OBD-II testing land. As long as you: 1) have passed all of the monitors (continuous AND non-continuous) AND 2) you don't have any DTC (Diagnostic trouble codes aka CEL) AND 3) you don't have any PTC (Pending Trouble Codes aka "I'm gonna be a CEL if this doesn't change"), you'll pass regardless of what year(s) engine(s) you have, because you aren't going on the sniffer anyway. Unless you fail the OBD-II check (as I understand the process).

Oh, and nothing disallows a motor other than OEM, as long as all of the original emissions devices are present, such as cats, all O2 sensors, EGR, blah blah. Which I happen to have (98 2.5 and 01 3.0 with all the original emission control devices present). On top of the fact that I pass the sniffer with flying colors anyway. FWIW, by the VIN the 2.5L HO engine comes up by default anyway.
