pros and cons zc dohc Vs. sohc

Im ordering my zc monday morning dohc or sohc?

the sohc zc isnt that much better than the d16a6 in your SI, so go dohc.

DOHC all the way.

I wouldn't say that, my SOHC ZC kicks ass. I was very suprised at the amount of torque it has. When I got my SOHC ZC I was just looking to put a replacement motor in the car. it is a really nice motor and the parts are easy to find as well. I was able to keep up with a B16 CIVIC untill we got to his VTEC, and my revlimiter kicked in.
your choice, just my opinion.

isnt the sohc zc an a6? just labeled differently? ide go DOHC tho, and are you keepin your hood, wing and mirrors white on your car?

actually i was talking to him just before and he was thinking about going with brite blue and white he thinks the green is just too brite and stands out too much the hood wing and mirrors are goign to stay white but the body is going to be blue..........im pretty sure hes goign to go with that

well you gotta remember im drivin a DPFI sohc zc ... im sure yours is pretty fast :D

the hood wing and mirrors are goign to stay white :apuke:

I like the rex green and white...

Im not sure what im doing with the paint yet i wanted some advice on that 2 im like 6 months from painting it but what colors or color schemes do you guys think?? thanks

black. nothing is sexier than a jet black car with plenty of clear coats that has been freshly washed.

I like the rex green and white...
i think it looks like it came straight outta tokyo extreme racer or it looks like a little toy car or something, but its what you like that matters

NO! Shit my b16 have more torque than that and plus i'm plannin to swap out my block with a 1.8 or sell my ride to start a new project!:)

what ever color you paint it just make sure it isn't black with a redflake with red ghost flames:D that would just be too many shaved crx's the same color ;)

yea, the b16, otherwise known as the tourqeless wonder

who needs torque when you have 8200 rev limit and VTEC

b16 = torqueless wonder = still badass

b16 = torqueless wonder = still badass you forgot overpriced! :D

Why do you have to be a fucking jerk-off? I was just making a compairison(sp). and I have both so I can speak from experience. I am not talking shit like I don't know.

so go fuk yourself!!!!

i think the big diffrence in the two engines ... SOHC ZC and the SI engine is that we produce a bit more torque at higher RPMS. i dont know of any actualy statistics cause its uncommonly used engine for performance. I used to have a 91 LX and this is a vast improvement. a buddy of mine drove my car, he is a hobby mechanic and has done work on both my cars, and actually said "wow".

I notice my SOHC ZC even though its running DPFI can handle hills infinitly better then my LX engine could. I used to drop like 10-15mph on a hill now i keep a steady speed all the way through unless im going over 90-95. and these aint no small hills either ... so dont let these b-series punks give yea shit man. switch your system to MPFI if you havnt already and show em what real men can do with a car.

sorry bro, I did not notice the wink, I just hate it when people get so negative about shit. I never reply to a thread/post that I don't know.
That is why I felt offended. I just seemed you were saying I was full of it.

Truely sorry,

Mike

The biggest difference in the ZC and the Si motor is compression.
don't know the actual numbers tho.

shit, i'll vouch for mike's car... that single cam moves pretty good... considering i had 17's on the car, four 15's(rims) in the trunk and me and my girl (no excuses ;) we was running good...
shit, i loved my single cam...
but cant nothing take me away from being able to rev freely to 8200 and just hear the vtec wailing...

my .02 cents
:)

Its all g man:D

I personally think the only real difference is the ability to slighty fine tune a DOHC better than a SOHC motor...but with the SOHC ZC only making about 5hp?? less than the DOHC, they are pretty close.

Like Melt said, the first key is making sure whatever motor you get has a MPFI conversion...DPFI is great for economy, but a performance system it is not.

I would say DOHC cuz I have one (albeit on an engine stand still :(), and I think they look cool compared to a SOHC, but get whatever works for you.

And to answer the Q from above - I think a DOHC ZC compression ratio is 9.5:1 and a d16a6 is 9.1:1, but I am not 100% sure.

Edit - ZC = 9.6:1 ;) I was close.

COOL:D

I personally dont know the specs but common sense will tell u a couple things which u can draw your own conclusions from.


the D16a6 has 108hp SOHC NON VTEC
the ZC has 130 hp DOHC NON VTEC
the D16z6 has 125hp SOHC VTEC
the D15B has 125hp SOHC VTEC

SOHC ZC 125hp SOHC NON VTEC??? <--- i dont see how they can make a SOHC 1.6L engine put out the same horsepower stock as the SOHC VTEC engine, unless the SOHC ZC has a wild cam, which i doubt it does.

If someone has a picture of a D16a6 piston, please post because i have seen the inside of a SOHC ZC block and want to know if the pistons are the same.. i am kind of wondering myself about the specs of the SOHC ZC, but like i said earlier, its a stretch to say it has 125hp. common sense says that if honda could squeeze 125hp out a 1.6L non vtec, then spending the extra money/technology on making a VTEC engine which was equal to that of the earlier NON VTEC engine is pointless.

Im guessing that if anything, the sohc zc is the same as a d16a6, or maybe it has 110hp instead of 108hp.. 125 sounds a bit on the high side.

I wish it could pull 125 ... it pulls more like 108ish as the Si does for the 4th gen. no one really does much testing on it cause they could spend like 50 bucks more and get the DOHC ZC instead ...
