I am new to the Honda world and was looking to buy a 89 CRX that has a ZC engice swap in it. What are these engines and is it a good swap to have in the car. Where did this engine come from(what type of car), and any other general info you can give me.

Thanks

 

The ZC comes from the JDM Civic, in which it came standard. It is a DOHC 1.6 L. I have seen published HP from 130-140 HP. Its performance is similar to that of the 88-91 Domestic Acura Integra DOHC 1.6L. It has, per most everybody who has a B series swap, limited potential. However i have benn using one in my '89 CRX and '88 HB and like its driveability. I go more for handling and a usable (daily driver) horsepower. THe Vtec motors have higher horsepower but who keeps the engine about 5K RPM to use it? It comes down to how much strainght line spped you want. The B series motors require an motor mount kit and will significantly increase transmitted vibration to the passenger compartment. I like them because the whole swap including an SI transmission was under $1K. It still gets between 28 (getting on it all the time) to 36 (highway miles under 75 MPH).

 

Youe mean the 86-89 tegs with the D16A1 the 90+ got the B18 which is not similar at all..
The ZC came in the jdm civic/crx Si's.
It makes around 130hp.

 

And yes it is a good swap but it has a slimmer/harder to find source of aftermarket parts

 

there are different types of ZC motors. theres the common DOHC ZC, SOHC ZC, and SOHC VTEC ZC. you'll need to clairfy which one your car has.

 

if you have a single cam zc swap, you have a stock crx si motor basically, they are physically identical....basically in everyway except some stamping.. if you have a dual cam, you have a JDM si motor...i have a dohc, and i LOVE it....good stuff. i have my head milled, better head gasket, exospeed stage 2 reground cams, and srr cam gears...with these mods it is a LOT of fun to drive.

 

Hey, red! I always wondered, why is a "better head gasket" actually better. I have a DOHC ZC as well.

i was completely unaware of the existance of the SOHC vtec zc... i would be quite suprised if you could actually proove this to me.

what is the engine code on the block??? what are the specs??

 

Better head gasket is an MLS head gasket instead of the shitty composite ones they come with. When going with head gaskets stick with stock Honda OEM.

Also it weighs 100lbs less, too, that shrinks the Hp difference between them as ZC has less weight to pull, Plus the ZC has more low ent torgue than the B16. I myself get 35 mpg with my DOHC ZC W/ZC box CAI Header and 2.5 catback, and that baby does fly. And I am in the middle of installing Stage 2 Exospeed cams in mine.

 

thanks for all the info guys. That is kinda what I was wondering!!!

 

i would pretty much swear by the cometic MLS headgasket i have....the shitty composite one i had was actually blown, but only slightly, i didnt notice much of a performance loss, i was loosing some coolant though. the cometic gasket is an excellent piece, fit REALLY perfect too. very happy with it....and i LOVE my exospeed cams.....top notch stuff

 

How much do the exospeed regrinds run? I have a zc sitting in my garage next to a 88hf that should be in the car by nex week..

 

THey are asking $250 plus shipping, last month they were running a special and think its over. they have a quick turnaround. I am in the middle of installing mine right now.

 

Gracias from me also. I'm the one purchasing the car and I'm new to the "ricer" world (no offense). I would be glad to recieve anymore imput you guys can give on my purchase. Here's what I'm looking at:

89 crx si
KYB struts, ACT clutch, full greddy catback with resignator chamber, relocated battery, intake, functional spy hood scoop, replaced axles, new radiator, strut bar, short shifter, chipped ecu, type R shiftknob and the ZC engine and new timing belt.

Thanks for your input guys.

 

I have a DOHC ZC swap in my 90 hatch. I've had the engine in for about a year now, and I love it. I just have normal bolt-ons, and even with full interior and a sub box, it pulls hard. And for the price, you can't really beat it.

Water pump, front and rear seals are easy when the engine is out but much less fun when its in the engine bay!!!!

 

Timing belt and water pump should be replaced too, either of these failing do to unkown age or milage and it WILL ruin your day, week and month in mere seconds.

 

My wife has a DOHC ZC in her CRX. I did all the normal boltons and that thing is quick. The price was right to...

 

yeah all that stuff souned great Huh? till I actually saw the car! I was a totally POS Nothing gets to me more than a stupid ricer punk who can't take care of what used to be a beautiful car!!!

yeah I know where you're coming from...
The Zc is great and down the line you can get a homemade turbo setup for cheap... then it'll be a lot more fum... TRUST ME
