94 civic coupe. EJ2 "D15B" clarification.
Hey guys. Just a couple of questions to help clear some things up for me. Before I ask I will throw my disclaimer out: I'm currently in the military stationed in South Korea. I've done done plenty of time on google, forums and other forms of research. If you're going to get on here and be a douche bag or a Internet boss and school me up or tell me to go to FAQs, I'm simply going to ignore you. As I stated I've look around and done about 4 months of research on EJ2S and D15B motors.
So that being said a few questions that I could get answered and pointed the right way. I've been reading on about all the D15B motors. I have a D15B *nothing follows NON Vtec. My car is currently back in the states with my girlfriend. I've looked around and I can't put my finger on the right stuff to look at. I get told I do not have a D15B. That something has to follow because only the D15B with no numbers is a 3 stage VTEC. When I had her look for the P-07/P08, she told me it wasn't there. I'm sure it is she is just blonde. Can someone clear up for me about my engine. I attached a picture of the engine bay she took for me.
Thank you guys for all the help in advance.

94 DX D15B7 5sp-------PMS-1. So she should look for the number PMS-1? Not P-08 or P-07 like I was told.

There is, according to wiki, a non-vtec D15B engine.

Letter-number-letter-number was the format used in some countries (America, among others). Letter-number-letter (without the last number) was the format used in other countries (Japan, among others). The D15B is a different motor than the D15B# motors. For the sake of maintenance, though, and given your head code, just treat it like you have a D15B7.

You're looking up jdm motors, not usdm motors. Thats why its confusing to you. Why not just have her take pics of the engine block code, the head code and post it up. All these words don't mean a damn thing.

Re: 94 civic coupe. EJ2 "D15B" clarification.
That's a PM3 head. That's literally all you need to know. D15B = 1.5L, leave it at that. These motors came in so many versions yet all use the same block code. Combine the age and potential head/cam swaps that may have happened and all the technical lists go out the window. You have a 1.5 block and a PM3 head. This reinforces "NotARaCist" assessment to treat it as a D15B7.
"Tyson" made a thread about the ZC engines. It demonstrates how the ZC stamp easily confuses people too. Just like the D15B the ZC came in many forms.

You are in luck, I was just researching D15B again and I came across a plethora of D15B motors listed beyond even what the wiki has, here on Honda-Tech.
I saved the post link as it appears to be the most complete list of D15B motors and what cars they came in I've ever come across.
The thread/post is found here:
https://honda-tech.com/honda-crx-ef-.../#post38262173
The head code is the equivalent of the D15B7 so quite likely the pistons are also the PM3 like the D15B7. A borescope can confirm that with a flat top piston with 4 valve reliefs.
