[chopstick1981]

just got done building a v8 with my dad, fun stuff! now i want to know what i can do to my little SOHC ZC, its pretty much the same as stock d16a6, i put CAI and exhaust on it, so what are my options short of N2O or turbo. I did a couple searches but nothin really came up relating to this motor.

the only way your going to get real power out of that engine is either nitrous or turbo. i mean you can get a good ignition system, camshaft, and head work but to make your car have as much power just to match a turbocharged sohc zc would cost much more.
N/a is a lot more than turbo. you might even want to consider saving up for a b series swap.

If you feel you absolutely HAVE to destroy EVERY revhead that blips next to you, then spend a fortune on a B16/18 swap, turbo it, add NO2, and drive around like a cool dude, and then shit your pants when the guy next to you pulls up in a Subaru, or Bugatti Veyron...

Or, spend less money, use what you have, make that SOHC ZC a powerful motor (some guys push out 487HP - streetable), with enough to satisfy yourself, because you DON'T have to impress that guy in that VR6. Believe me, he is NOT going to give you applause or a medal if you DO beat him... and you'll have more money for other mods on your car.

And lastly, remember that your motor is a ZC, not a D16A6. There are differences...

did you not read my post? i said making an n/a sohc zc, would cost alot more than a turbo sohc zc, and the n/a zc would not make nearly as much hp as the turbocharged one would. i highly doubt you can make a 487 n/a sohc zc or even a turbo charged one. and streetable? right. you think that a 487 hp sohc would cost less any b series swap? i spent about $2100 for my whole ls swap. if you can give me a 487 hp sohc swap for cheaper than that i will buy it.

ive been down the road of trying to moddify a d series engine. i recommended him to look into turbo if he wants to break into decent numbers. but when you consider the cost, b series is actually cheaper, more reliable, and has much more potential. please dont talk about b series swaps if you never had one.

i can tell you about b series engines that have gotten more than 600 hp. but who cares. what do i know, ive never felt the true power of the monsterous dual carbed zc.

i hate to burst your bubble like the rest of these guys, but they're right.

without a SHITLOAD of money, an NA d series really cant compare.

you could spend money on bad ass 4-1 header, a stage 4 cam, exhaust, intake, etc. etc. and still only be as fast as a stock b16.

for the money, you cant beat a B series swap or a D series turbo.

you could build a 13 second d series turbo kit for under $1000 and smoke b series, unless of course if its a turbo b series, then you are beat

You missed the point. He asked what can be done to get more power from his SOHC ZC... read that again... SOHC ZC...

NOT a B16. If he wanted to know how to get more power from a B16, he would have fuckin' asked for more power tips for a B16... But he asked for help on a SOHC ZC. He knows like any other person out there who wants the most power it makes more sense to "swap in a B16, turbo it, add nos and have 600HP". Because to amount to anything in the honda hopping scene, you HAVE to have a B16 swap ...

That was not what he asked for... he asked SPECIFICALLY for a SOHC ZC... wait, let me look again... nope... he NEVER mentioned a B16!!

If he asked how to build the world's fastest and quickest honda drag car, then it would have been appropriate to suggest the B16 with the kitchen sink thrown in. But I think seeing as he asked for ways to make his SOHC ZC faster, I thought it appropriate to talk about the SOHC ZC.

But what do i know? I just want to help the guy with his query... what right do I have talking about the ZC (which he asked for), if turbo B16's can make 600HP. Silly me. How dare I suggest anything different from a turbo'd B16 if all the guy is interested in is a ZC?

Now, for chopstick1981: Seeing as you asked for mods short of turbo and/or NO2, go NA. Don't worry, I won't waste your time telling you what you SHOULD do for maximum power, I will tell you how to get more from your ZC...

get some PM7 or P29 pistons from a DOHC ZC or older Integra D16A1 (PM7 and P29 are identical pistons). They are domed pistons and will push your compresion up to 11:1. They are relativly cheap pistons. If you mill the head a further 0.030", you could get it to 12,5:1. Port and polish your intake mani and your head, make sure to port match your intake mani flanges with the head also. You already have CAI and exhaust. If you don't have headers yet, get some, preferably DC Sports or Bizimoto, get an adjustable cam gear for best timing, keep your stock cam, the SOHC ZC cam is more aggressive than the D16A6 cam, unless you want MORE, then get an aggro'er cam. But the stock ZC cam should suffice. Get a fuel pressure regulator if you want to...

Also, make sure your engine is happy, healthy and regularly serviced. You have no idea how much power you gain from an oil change... lastly, for better performance, slightly overinflate your tyres, keep your tank at quarter full, drain your window washer, etc... put her on diet.

thats all fine and dandy, but since he was building V8's i figured he would like a little more horsepower than 140 or so.

If not, this is another OMFG WHAT HEADERS DO I GET FOR MY MOTOR WITH ONE HEADS??@# thread.

and also, with p29/pm7 pistons AND a milled head (please do not mill the head), the stock cam is okay, but something like a high lift stage2, it is very likely that your pistons will slam the head on the way around.

how do you get around this? well, you weld up quench zones in the head to effectively make the combustion chamber smaller without milling the head, and then you may even have to use a thicker head gasket.

Im basing this on the fact that a high compression engine needs a big cam to function properly and vice versa.

Ah, Finally, someone who understands what these forums are meant for... giving someone advice who asked for it. It is nice to see people put their knowledge together in the spirit of what these boards were meant for...

I have to concur. Even though I said IF YOU mill the head, it is preferable that you don't, quite correct. The last thing you want is timing problems, or slack in your timing belt

ha funny, i never mentioned b16 either. i said b series!(b18 a/b, b18c, b20)

why would he go with a b16 to be the worlds fastest drag honda???

all i got to say is Wow. the awesome power of the oil change.

[D15Bitch]

Who said I was talking about you...?

ha funny, i never mentioned b16 either. i said b series!(b18 a/b, b18c, b20)

once again, who said I was talking about you...? I was talking about B16's... the next time you get something, just get over yourself...

why would he go with a b16 to be the worlds fastest drag honda???

I am ripping off the stereotype, optimus. The B16 has been deified as the ultimate in civic performance, or so most believe... it is obvious that it is not, but I do not need your permission to point fun at that...

all i got to say is Wow. the awesome power of the oil change.

You are like a christian fundamentalist: just read what you want to... it shows small wit on your behalf to point out only one sentence in an entire paragraph about engine maintenance... when all logic dictates that an oil change MUST improve the performance of an engine... basic laws of physics, Jim, ye canna chenge dem...

okay folks ... i only read ZC related threads and its a shame i have to bother checking this one. You guys should put em back in the pants and count to ten ... thats it ... breathe and 10 9 8 7 6 5 4 3 2 1 ... okay ... enough ... unless you have something interesting to say TO HELP THIS GUY ... please keep the name calling and insinuations to a minimum.


To the point now ...

Alright, congrats my brother, we share the sock ZC disease. More powerful then stock but not powerful enough to sate our desires.

Alright well ... i can tell you that the aftermarket support is hard to find as almost all the refrences to just "ZC" are for the dock engine. So good luck there. Be glad you dont have a third gen prelude cause thats even worse. You basicly want to look for parts for the Si i believe cause they are ALMOST ... and i say ALMOST ... exactly the same in terms of parts fitting and where things are. I just cant place one thing and i think its cause mine is an auto. So, your looking to get more out of the engine. Headers to complete the IHE combo. Then start thinking about how much money you REALLY want to spend and how far you REALLY want to take this engine. cause unfortunatly nothing after that point is going to be cheap.


I will leave you with this so i can hear your responce and perhaps help a fellow sock zc brother out.

I agree with you dude. All I want to do is help this guy, like I did in earlier posts with piston info, etc. But it seems EVERYTIME I try to help ANYONE with info regarding "sohc" or, dual carb" or "ZC", Optimuscivic feels the incessant need to disrespect me, and anyone else who would have info or questions on "sohc", or "dual carb", or "ZC".

That is what these forums are for. To help people with questions by answering them if you have knowledge to share. Not to piss on anyone who might have a different setup from you or believes they can get power "without" having to swap in a B-series... everyone knows the superiority of the B-series engine, but not everyone cares, or has the opportunities to have some garage swap in a B-motor for them, so they can drive around like a hondagod... just 'coz they like their B-series motors, does not mean everyone else HAS to aswell...

But if Optimus has to have such a violent reaction to anyone having questions about sohc, dual carb or ZC, then his life must be pretty uneventful...

hahaha what are you going to cry now?

[91civicDXdude]

...BACK TO THE QUESTION AT HAND....

for moderate power and enough that should make you happy, complete your I/H/E combination, look into a cam (there are many more cams for the d16a6/sohc zc than the sohc vtec even, if you're going to do it, do it right and get a big cam, smooth idle is for pussies), get a d16y8 head gasket (thinner higher compression without milling), throw a d16y8 intake manifold on for good measure, and if you do so, get a 58 or 60mm b16 throttle body, port the intake manifold-to-throttle body opening.

keep in mind this is keeping with the stock bottom end for ease of installation, as well as a little easier on the wallet, not having to pay machine charges for honing the block, cleaning the block, decking the block, plus the price for rod bearings, main bearings, thrust washer, main seals, etc. etc.

throw in a little head porting and you could be up around the 140hp mark or so

[D15Bitch]

hahaha what are you going to cry now?

no, you're the one who looks like an idiot... imagine it, a group of guys standing together, chatting... someone asks a question about a specific problem they have, like, say, how to make a more powerful motor WITHOUT having to go turbo or no2... and some dick pipes up and says... hey, dude, you should go turbo or no2!!!

That's you, duncecap...
