THANKZ

ZC

imported_loudsubz

Going strictly on reliability issues, id say the Z6. I was doing a bunch of research on the ZC when i was looking at a 4th gen civic, and peole I were talkin to with the ZC said they were having probs.

Although there are some out there with Zc's who have 0 probs, its just my opinion.

ZC has more a little more power but reliablility isn't great

SilverCRXSi

ZC since it was designed for the car. Direct swap.
Yes the d16z6 is newer and has more after market parts but the ZC can be tuned better (2 cams are better than 1)
I've done my fair share of research and I've conluded that the reason people "blow" their ZC are because they dont take care of them.

Example: ZC's have been sitting in a warehouse for about a decade now. People swap them in because its a cheap swap and fairly straightforward (I doing it for that reason too.) But heres the same thing I've seen happen over and over again.
They swap in the ZC w/o replacing any of the gaskets and seals and belts (which have been sitting for 10+yrs) and then don't even "work" in the engine again gradually but drive it like a bat out of hell.
And then they wonder what they did to mess up the engine 6 months later (which just happens to be when most shops warranties run out, hmm... I never thought of that 1...) well atleast the shops I keep hearing about from the CRX boards in the US.
Why you hear less about b16s I dont know? Less of them around? People take more care of them? Who knows?

Thats just what I think from my observations.

My advice is regardless of which engine you get unless you have the cluster gauge with it so you know the milage for sure, get it rebuilt. It'll save you lots of headaches down the road and work it in properly too!
I'm planning on getting a ZC in the spring and I'm going to have it rebuilt.

I'm not an expert on ZC's nor do I try to act as one. These are just my opinions. I am open though!

Good luck!

the zc is a great motor, it runs perfect without any problems. But if you want power i would go for a dohc vtec motor. I was thinking about the sohc vtec motors and there also newer than the zc's too. I can tell some people don't know what there talking about when it comes to the zc

KS-R

For an EF chassis.. I would go with the ZC DOHC motor.. It's really the best bang for the buck.

/\ now thats a sig Bitch


But why did you dyno without the Slicks on?

KS-R

Dynoed in 4th gear, so no need for slicks.. besides.. it's strapped down as well.. so more traction.

SilverCRXSi

And you do?
You asked for an opinion in you last thread and it given. Doesn't mean you have to agree with it. I gave my reasons why I thought you had the problems you did with your engine. Thats.
I don't pretend to know everything about the ZC because I don't.

Anyways you are correct about the b16 (for real power). But this thread isn't to bitch but rather to try help someone out.

Now lets all try and act like mature adults and not little kids fighting in a sandbox.

You can save and do up a SOHC as well. Just comes down to how much money you want to lay down. There is a CRX for sale with 500hp from a d16 motor, running like 24lbs boost.

i think i do know about this motor b/c i've been running it for over a year now and i went threw alot of races with it. The way you imputed your reply is telling me that im an idiot and i don't know how to run this motor. I actually solved the problem and it was the oil cap, the o ring was missing so oil would sneak out when i drive and that's how i lost it not b/c i beat it a year ago. Anyway i don't want to waste my time explaining this any more you just wouldn't understand. Thanx for helping me out silvercrxsi.

Anyway back to topic as i said earlier, the motor runs amazing no problems, people on the board are saying that it's not reliable but i haven't had one problem with the motor since i bought it myself, i put 30k on it with no problems what so ever. I would say for the price and drop in rates this is the best swap for a 4th gen h/b or 2nd gen crx. You do feel the power, the motor has a lot of potential but if you want to make this motor push over 200hp you have to rebuild the block and the connecting rods will definetly snap on you, no question about it
When you do the swap do it complete, get the equal length drive shafts with the zc tranny, 88-89 teg ecu and your car will go quick.

Hope this helps, good luck

SilverCRXSi

my blue si: sorry if you thought i was callin ya in idiot but i never intended that. I've just seen many posts before (not on here) of kids dropping in a ZC and then driving it F&F style. You made it sound like you had done that too. Sorry man. Glad you found your problem and fixed it though.

Anyways back to the thread.

SweetCivicGurl

ZC's suck!

imported_My Blue Si

u suck

civic-coupe-kid

if anyone is interested in a 'blown'jdm zc dohc, please shoot me a pm ...
parts are salvagable if you need some parts(tell me what you need and i'll tell you if its still good) or you can get it rebuilt if you want. i also got the zc tranny with it along with an 88-89 integra 5spd ecu for sale if interested as well.

thanks

SilverCRXSi

ZC are good, why? 2 cams are better than one...
I'm done...

Ofcoarse if you can afford a b16 by all means...

imported_loudsubz

Yeh but d16 can have potential too.

Rice Burner

You can get a ZC motor for $500-$700, direct bolt on for 4th gen.
B-16 will cost you approx$3500-$5000 after all said and done. And then it's just a stock, non-rebuilt b-16 motor. Through in some add on's after and your looking at roughly 7k.
I'd rather get the ZC (if you don't want to spend shitload of money) for 5-7 and then rebuild the motor, port and polish the head, knife edge the crank and your still below 5k. Or don't rebuild and add on a turbo. But your risking it there. But then again it's just a $700 motor, go buy another one.
Just my thought's.

Rice Burner

Yes they do, I had a D16 (non-vtec) that ran a best time of 14.3.
