Ok so I went down to this shop that I work on my cars at and I'm messing around with my CRX. The owner says something about how he just got a honda engine back that he sold to someone and it's in this truck outside. So I walk out and look at the engine and it looks like a B18, but I'm not well versed in the engine area so I was gonna ask you guys. So I went to HMotors and it looks like the B18 they have on there. It has the 4 spark plugs right in a row and the different looking valve cover. I noticed at Hmotors the ZC head looks the same but that was a JDM engine right?? It's definitely not a D series. The owner said he THOUGHT it was out of an 89-90 or something like that Integra. He said the guy he sold it too was trying to put it into a newer Integra he thought but that it wouldn't fit. That didn't make any sense to me but whatever. You're probably thinking, why didnt you just find the stamp?? Well I looked but the engine was so caked with oil and dirt I couldn't find it. I sprayed it down with a bunch of carb and brake cleaner but still couldn't find it. I was dressed nicely so I didn't want to mess my clothes up cleaning the engine. Anyway I am hoping it's a B18, he said I could have it for like $100. He said it ran, he pulled it out of a totaled car and junked the car. Basically what do yall think the likelihood of it being a B18 as opposed to a ZC is?? If nothing else I'll take my digi down there and snap some pics. Thanks a lot for any advice ya can lend!!
