zc:
1595cc
4 cyl, 16valve
DOHC
9.1 c.r.
137 bhp @ 6800
Redline: 7200 rpm 108 lb-ft @ 5700
z6:
1590cc
4 cyl, 16 valve
SOHC VTEC
9.2:1 c.r.
125 bhp @ 6600
Redline: 7200 rpm 106 lb-ft @ 5200
the zc i would think would have better power potential. it will most likely have less kms on it...but they are getting harder and harder to find. you will get the z6 for less guaranteed. if your trying to keep it very inexpensive you could also do a "mini me" swap. which is taking a z6 head or y8 head and putting it on your stock block... |

| I have a 90 DX for a winter beater and it's starting to blow a little smoke. Just as a ball park, what do you think I could find for it with lower KM's and what kind of price range would I be looking at?(just for the engine) I would love to find something with 150K-200K km's, what do you think my best option is? I don't care about power, just cheap with good seals! |

i have two of your exact engines....ones here in my garage and ones in my old car....never used the one thats in my garage but the one on my old car had a small oil leak....im not asking very much...if you'd like either one you can make me an offer |

| Sounds good, but like I said, I hav eno idea what kind of price range I am looking at. And if it's to much then There is no point doing it as the car is just my winter beater. |

well if its just the beater than i wouldn't worry....they go for quite awhile.....but if something was to happen or you wanted to be sure i would let either go for less than 100 |

| Was that supposed to be $1000 ? Did you miss a zero? |

a ZC engine has some good power, a friends 91 DX hatch had one and he was pretty quick, good little engine. WIth the d-series you get the nice option of a low boost turbo kit for cheap but meh. I vote on a ZC engine but its yourcall
for just the engines they are pretty cheap, if you want the tranny and everything expect around 800-100, but for my 79 civic i looked at a relatively nice ZC engine and for pretty much all the parts it was 550 . |

Yeah all I need is an engine. My tranny is OK, the ussual little grind into reverse, nothing major. I have the single fuel injector, 1.5L engine, not sure of the engine code on these? I would love to drop in the mutiple injected engine, supposed to get better millage, but the engine I got in her now does the trick!
So, droppedatbirth...... You have an engine for under $100 hey? What can you tell me about it? What kind of condition, KM's, year, you know....all that good stuff! This is the exact same engine I allready got you said hey, so I wouldn't need a different ECU? I have all the time in the world to install stuff and work on the car, but never enough cash! Anyway, please let me know some details! |

i have 2 engines i could sell you for under 100. one is in my garage. head is complete and ready to go. bottom end is in pieces and i think missing a couple things...not sure on what its missing you could check it out if you'd like. unknown kms on that one
the other one would be in my old car. jsut under 70k on the rebuild but it is leaking oil. since i suck at anything mechanical you would have to take it out of my old car yourself...i could help you but i don't know what im doing.
and yes both are d15b2 engines which is exactly what you have in your car now. you wouldn't need a different ecu. just straight drop in.
if you'd like to know anything else just ask. |

Yeah...what is this oil leak like? Where is it, how bad? would it be possible to get a pic of the leak area? When and why was it rebuilt? By who? still have receipts? Anything else needed on the engine?
Is this civic of yours with the leaking engine wrecked or something? |

oil leak is....like an oil leak! doesn't loose that much oil....infront of my house theres some stains on the ground...hard to judge how bad it is....i have no clue where the oil leak is....its a commmon problem on these cars to have a leaky oil pan...which could be it..
the engine was rebuilt by the previous owner and because he was thinking the engine was near the end of its life. don't have the recipets for the engine. engine is complete and was running perfect before.
and yes the car is completely written off sitting at my work because im parting it out. |

I used to have a zc in my crx at one time running on a PG7, and yeah it was Ok. If I can do it again I would rather do the Z6. Its alot better of an engine IMO. Although some parts are made for it, its alot harder to source parts if your doing a build.
Ony downfall I see is the obd0---->obd1 conversion. Well worth it though.
BTW the obd0 zc does not come with 137hp. The obd1 zc did though. OBD0 zc is rated at 130hp. |

Hands down imo the D16Z6 is a WAY better engine. Sure the ZC is a DOHC Motor, but it lacks the aftermarket potential that the Z6 has. It is almost impossible to find performance parts for the ZC, where as, the Z6 has HUGE aftermarket support.
I would also recommend looking into a JDM D15B Motor. They come stock with 130HP and are also a VTEC Motor unlike the ZC.
Something a lot of people do not know as well, is that in Japan they also made a SOHC VTEC ZC Motor. It came stock with 140HP and has the same head and block casting as a USDM Z6.
There are a lot of choices out there for a D-series motor, but I would look into getting a SOHC VTEC motor...well worth the money and have great potential!
As for the price, you can find a used D16Z6 for a few hundred, but they are usually high millage and a rebuild would be a good idea. Instead of spending the money to do that, I would recommend a JDM motor, like the D15B VTEC. You can get them for about $700-$800 for the complete swap. (including the tranny) I know you said that your tranny is still good, but if you are planning on doing a swap I would suggest a tranny swap as well. The Z6, Y8 or JDM D15B all have WAY better gear ratios than the other shitty D-series trannies. This makes a HUGE difference in acelleration.
Hope this helps |

| Yeah, but where are you going to find a cheap/low millage engine? Ussually, no such thing. I like the sounds of 130-140HP in a car that came with 90HP. That's a BIG increase in NA power!! Too bad you can never find a cheap/ low millage engine! |

Well if you read my post you would see that I recommended the JDM D15B VTEC. They are low mileage and the motor can be found for about $500-$600 for just the motor. These motors come stock at 130HP and have the most agrressive cam of any SOHC Honda motor. |

And if you read my post I said "where can you get these low millage engines?" |

| Have you looked at a B16A1 swap as a option, they have come down in price a LOT in the last while now that everyone seems to be moving to K series engines as the swap of choice. |

Personally, I am looking in the couple of hundred dollar range!! I am not looking for a upgrade so much as just a replacement since my seals are wearing out.
However I do think a DOHC VTEC is a great engine! I had a integra GSR for a few years and man was that a solid engine! Lot's of fun, easy to work on, everything you could want in a cheap high performance engine! I would love to drop one of them in my old 90 civic, be a blast! But the engine would cost what the car is worth! |

This is true yes, very rare to find one.....but, where the hell are you getting your # of 140hp from????? :confused:
The sohc zc vtec is the SAME as the d16z6. It is also rated at the same 125-127hp. Just needed to clear this up for people reading. |

Umm k-swap is not the swap of choice for most EK and EG people. They dream of it, but majority are either turbo there d-series or still look at the B-series. Some are even doin the h-series now which i must say are puttin down better numbers then K-series on motor builds.
If i had a lot of money i would do a k-series swap, im still thinkin about just addin more aggresive cams and some fuel stuff to my b18c1/5 and once it dies gettin a k-series and keepin the b18c for a daily driver rebuild sleeper
Either way , not alot of engines out there low KMs , low kms means a lot of things but for me thats like 40-80,000 anything higher is normal until 130,000 then thats high
If you want good pop and a nice engine b16 is there, d16 are a great choice tho, cheap and you can put low boost on later in life and have tons of fun.
For me the b-series is a great engine but it all depends on the coin, i still vote for the ZC if you are going that way, but if not the b16 or d16z6 or y8 are great motors as well |
