@ OP:
Yes, always check the FAQ, first.

Though since it's kind of a mess right now (I'm in the process of rebuilding it), I'll point you in the right direction.

There's OEM engine codes here:

As for where to find the engine code on your engine (ie. you're not sure if it's the original engine), I'm not sure if there's anything in the FAQ about that (though there should be, it's asked all the time, maybe I'll do a write-up on that if I can't find one :-?), so I'll straight up tell you: When looking at your car from the front, look to the left of the header, and follow the side of the engine down (still looking from the front) until just above where it meets the transmission, there's a block there and the engine code is cut into it. It might be a bit dirty, though is fairly obvious.
