I have a CRX not sure what to do tryign to make a desscion.....

 

They're both the same thing except for the o2 sensor..So I would get the d16z6 ,easier to find and cheaper..

 

I heard that the zc motor breaks easier than the d16z6 is that true... the ONLY thing different between the 2 is the o2 sensors?

 

The dohc zc motor is the one that breaks easier..Spins rods bearings easily and has very thin rods..

 

zc has 127 hp.. z6 has 124... i think.

ive got a twin cam zc in a 91si crx and a friend has a z6 in his 91hf crx. theres about a 300lb difference in the cars with drivers (his being lighter).

weve both got i/h/e, both have test-pipes and aftermarket clutches. he's got a fuel rail/fpr

using the crx si ecu we raced, i pulled hard until 90 (5-6 cars) and then he began to creep on me.

i then swapped the ecu for a obd0 ls integra, and we raced again; he never started gaining on me.

so, zc has more torque.. is cheap and easy to find, and you can use your stock everything if you've got a 90-91si

ps, my zc has 90,000 miles and is revved to 7200 almost daily. still running strong.

 

I thought this guy was was talking about a sohc vtec zc..My bad..But I would still get the d16z6 over the dohc zc

 

why do i always hear about how the ZC breaks whats your opinion on why their engines break so easily , i dont have the si crx i have the dx 88, i know its probobly best to get a si transmision and a ecu matchign the engine, i'll have to get mpfi and new throttle cables anyhtign else? I want to have power in my car but being able to drive it for years so i dont want to be to hard on it, or else i would just get and ls engine, i want compatability, so should i sacrifice the 127hp of the zc and take the 124 hp form the Z6?

They dont like being reved..
Actually the 5spd dx tranny is the same as the si tranny 1 through 5 gears..The si tranny has a little higher final drive,,but thats it..
Yeah do the mpfi conversion,,And if you can find one get a dohc zc ecu..But if not a pm6(88-91 si) will suffice,and you can always chip it with zc dohc maps later..,alot of people say you can run the 88-89 integra ecu..But the rev limit is way to high for a zc motor and it makes the motor run pig rich,,

 

ok i heard what u had to say and i guess that ur also sayign the ZC doesnt liek to be reved what abou the Z6 ... a little more durable?

 

my SOHC ZC is awsome, It pulls hard and I havent had any problems so far, you just gotta keep on top of basic maintinence.

 

i have crx si with dohc zc and i have rev it high few times and nuttin has happen.sinced i had it it only seen redline twice.redline isnt making power just winding it out.now since i have owned a dohc zc i would say go for single cam.do mini-me head swap.theres tons of parts for the single cam.not really **** for dohc zc and if u do find something they want to much money for it.only thing dohc zc is good for is boost thats it.

 

You said the Zc and Z6 are te same, guessing the only differenences besides what u said abou to2 sensors is tha tones JDM and ones USDM. Just recently learning abou tcars, first crx first car, anyways..... i just starting learning about whats in an engine. i get the basic idea. Someone said the rods are different in zc they are weak or something. Any descripitive info on why the zc and z6 engine are different is also what im looking for other wise already been helpfull for me comeing to a conlusion

 

D16z6 has VTAK I've got one in my car and I love it. I'm also glad I picked it over a B16 or B18a

Nah..When I said they were the same I thought you were talking about the sohc vtec zc motor vs. the d16z6..But the 88-91 dohc zc is different then the d16z6..
Dohc zc(88-91 version) is pre obd,,D16z6 is obd1
Dohc zc is dual cam..D16z6 is single cam
Dohc zc is nonvtec and d16z6 is vtec..
D16z6 is stronger then a dohc zc motor..Ive seen stock internal d16z6 makinh over 220hp with a turbo setup..dohc zc motor has paper thin rods so I wouldnt go over 200hp..

b18a would own you. lol

ALOT more torque than even the dohc zc.

"alot of people say you can run the 88-89 integra ecu..But the rev limit is way to high for a zc motor and it makes the motor run pig rich"

it makes more power, and just because you raise the rev limiter DOESNT mean that you have to rev higher.

if i had a stock z6 i wouldnt push over 200hp either.

 

I have a turbo d16z6 in my rex and am 9 lbs daily @ 213 whp for months without any sign of breaking. People need to give the d (especially d16z6)series more credit for their strength and reliability as I've seen stock motors run 250 hp on a good tune.
