i want specs!

i have had an 04 focus zx3 for about a year now. i'm wondering exactly what kind of engine is in my car and all it says on the engine is "DOHC 16" -- i'm just curious whether i have the 2.0L/130hp or 2.3L/144hp model. i'm also wondering if it's the "zx3 comfort" or "zx3 premium" trim. is there any way to figure this stuff out without original paperwork? i bought it used. should the dealership i bought it from have record of this information?

In my 02 focus, the engine size is written on a sticker under the hood. It has 2.0L on it. I have a premium and as far as I can remember, the premium has alloy wheels and a six-CD changer (?).
What I am confused is zx3 vs zx5. I have a 3-door and I assume it is a zx3. And also, the eighth character in my vin is 3. When I bought the spark plug wires from autozone a few months ago, it didn't fit. The guy told me that I have a zx5.

if it's a three door, it's a zx3. a five door would be a zx5. mine has alloy wheels and a button for a cd changer, but there isnt one installed. it has the blaupunkt mp3 player instead. i've heard some not-so-great things about my stereo on here and despite all that i think it's a bitchin setup considering it's stock. the number 3 is also the eighth character of my car's VIN. i looked under my hood for any kind of sticker or logo to indicate what kind of engine i have, but i couldnt find any. i'll look again. or maybe i'll just accept my car for what it is and end my quest here. i havent decided yet.

A 3 in the VIN code means you have a zetec, a P in the VIN code means you have a SPI. I'm not sure what the code is for the 2.3, but I think it would be obvious.

The 2.3 (and the current 2.0) are Duratecs. It's a pretty obvious difference. Duratec has the intake on the front and the exhaust on the backside of the motor.

i am about 90% sure that the 2.3's only went in the sedan and wagon. if its a hatchback it is probably the 2.0.

hope that helps or maybe someone will stop by and correct me.

The 2.3 was used in hatches in the green states

oh ok, cool
