wow looks really clean. im not very good with the older engines by looks, but there should be a plaque or engraving on the lower engine block that gives you the engine code (like b18, d16, etc). if you find that, i can tell you more about the engine you have. ofcourse im not sure what else may have been done to the internal parts. he didnt give you any details?

please please please please please please please please please.... your new to the car world, please please please please please DO NOT buy into this jdm ****. Please don't you'll be miles ahead of everyone other noobie out there is you don't fall into that JDM trap. Coilovers are not JDM, they are aftermarket. No stock honda EVER came with coilovers. The short shifter yes also is NOT jdm as this would imply that this equipment came on a factory Honda in Nippon. It didn't so please please please I'm trying to help you here, don't fall into that habit.

it looks like a d15b7 to me if I've ever seen one. So I google it and voila:


look behind the exhaust manifold on the front of the block on the passengers side close to the transmission. You should see it there. This is on a DOHC but its in the same location.

+1...

As a side note.. please buy a car cover for that thing and get an aftermarket alarm on it. Keep it inside and don't show it off. That car WILL get stolen at some point if you're not careful.

And yes, that's a b7 from the looks of it. Gotta love Google.

Thanks guys for the help I really appreciate it and is that engine A good engine or what?

 
Rep Power: 222

what makes a good engine to you? That question is as subjective as is the answer. To restate my question, what is your definition of a good engine?

Like hp torque Just the spec of it

im not trying to be an ******* but let me give you some advice. There are three types of people on Honda forums, the horrible ones that should end themselves 5 minutes ago. The mediocre ones who SOMETIMES beg the question "is it EVER too late for an abortion?" and the remaining 9% are role models for the rest of us who can only wish to reach their level of greatness. If you wish to reach that EPIC level of EPICNESS and not fall into the other two undesirable categories then take this second piece of free advice I'm giving you. Open a new tab in your browser and use google. Just type D15b7 engine youll get a wikipidia link and find it there and youll find plenty of links to give you the specs your looking for.

Look at this as not only a way to get answers to your questions, but an expedited crash course in better forming = happy forum time

once you get the specs you are looking for decide if this engine makes you happy in pants. If it doesn't then use either the search function here or the search procedure previously outlines above and find the answers to the questions for which you seek.

finally found some info from my honda tuning books. there is actually a ZC engine.

Honda ZC engine
DOHC
1.6L, 16 valve MPFI
137 HP

this is a true jdm engine and has never come stock on any usdm honda. Only installed on late 80s and early 90s jdm civic si and crx si. similar to d16a1 but with more hp (due to higher compression ratio and performance camshaft). it is actually somewhat in high demand and normally goes for around $2,000 for the engine. looks like you got a pretty good one here.

 
Rep Power: 222

in his picture, his engine is a SOHC. To the OP, the ZC is a d16 engine from the Civic Si (EG) and Del Sol Si if im not mistaken. The valve cover in your picture was only on the d15b if I am not mistaken. If the block code said zc and you have that valve cover on that block then I would venture a guess and say that someone swapped over a nonvtec head onto that zc since that valve cover doesn't work on any other block?! this baffles me more than the plot sequence of an M.Night Shemilan movie.... and I way out in the ether on this one?

this is a d16zc

found more info about it online, similar to whats in the book. if his engine says zc on it, im not sure what else it could be. but the valve cover is totally different than the zc so you may be right about head swap.

Id assume so. The DOHC ZC is completely interchangable with the SOHC ZC the z6 etc. All SOHC parts are interchangeable with the DOHC ZC making it a great budget swap for EFs. And they are cheaper than hell.
