Performance Cams for D15B4?

[Rufes1]

Hey there, I am in Australia and have the d15b4 (Dual Carb) and after some performance cams or other good engine mods.

I'm not def going to get them at'm cause I know the engine wont provide much power gains however I just want to see if there is anything available in the US as there are non here in AUS.

If you guys have some of these parts or know of a good dealer please post

You could get a cam from Webcams for the 1.5/1.6 SOHC non-vtec engine over the internet.

Some guys like to put the D16A6 cam in their D15B2's, but seeing as your D15B4 dual carb already pushes out 105HP, and the D16A6 pushes 108HP, I do not think the D16A6 cam will help you lots.

You could source the cam from the engine I've got, the ZC SOHC. They came in older integras and 4th gen civic sedans in Japan, and pushed out 120HP.

Also, don't believe the whole "B-Series is better" hype. You can make very decent power with your D15B4. The SOHC engines can hold their own when tweaked some. The fastest and quickest ALL MOTOR honda at NHRA is a D15B with dual carb. And he raped DOHC's and VTEC's regularly. Cams are merely there for one purpose: opening and closing of the inlet and outlet valves. One cam opens and closes valves just like a double cam. In fact, a single cam, means less reciprocal mass is used by the engine to turn it. Two cams means the engine has to overcome the resistance of twice the reciprocal mass as one single cam. From the same bore and stroke. That is why most of the DOHC engines have higher compression ratio's: to overcome the disadvantage of twice the resistance of one cam. Raise the compression ratio of a SOHC D-series engine to that of a DOHC, and you will probably put out the almost same HP as the DOHC, if not the same.

As for carbs, some people here will scoff at "old technology" like that, but those Keihins are very good carbs, and are very tweakable. And they are also PGM-carb, meaning they measure athmospheric changes, just like FI. Carbs are NOT a bitch to tune, and they also do not "detune" themselves, unless you attack them with a hammer...

True, you can have performance AND economy with FI. Whereas carbs give you the choice of performance OR economy... but with carbs you can have much more performance OR economy than with FI. It is also much cheaper to tune carbs than it is to tune FI. Compare the cost of larger throttle bodies, larger injectors and fuel pressure regulator, as well as ecu programming, to the cost of boring, rejetting and tuning a carb. Carb tuning is just a lot cheaper. And many experienced all motor racers will tell you that you get better torque with carbs because you get much better atomization with carbs. Tests performed by Bizi Ezerioha revealed that FI only got the same atomization as carbs at a distance of 3 feet. None of us can fit a 3 foot inlet manifold into our cars...

I say, use what you got, enjoy it like I have mine, and get the best out of her. You will get more satisfaction than just merely "swapping in a B16". I have more respect for fast SOHC's than for fast DOHC's.

haha u make me laugh. the "b series hype". i guess honda made a big mistake to make the B series, should have made them sohc carbed huh. even though bisi did all that he did with a sohc doesnt mean that everybody with a sohc can. i know it would cost a lot more to make a 10,11,12 sec. d15, then a b16,18,20. i mean theres so many n/a B series in the 12s, and i hardly know of any d series that can even reach that. just admit it , you are a lowballer, you have no money, and you pretend that your little sohc is a good as a dohc. whatever lets u sleep at night buddy.

As I've said to you before, not everyone stays in the states, but you show typical yank arrogance in thinking that the world stops at your borders...

Firstly, some people do stay in other parts of the world, and they do not have the luxury of popping in other engines for $400.00. Which you consider small change, but to us it is more than a qualified engineer makes in two months salary.

Secondly, most "other" countries got civics with carb setups, and not with FI, because of the markets in those countries, as well as the climates of those countries.

Thirdly, if the SOHC's are so bad, why does Honda continue to manufacture and install them in all their civics? In fact, very few places have ever sold civics of ANY generation with DOHC engines as standard. When was the last time you could buy a stock civic with a DOHC where you live?

Fourth, calling me a lowballer because of my liking for carbs and SOHC's shows your infantile mentality. I don't insult you for liking what you like, do I? But I am sure people like you said the same to Bisi...

Fifth, compared to you, I might be financially challenged, but that is because the country I live in considers $400.00 a VERY good salary. Very few people here earn that kind of money. Here, I am considered to be a fair earner, but compared to what you earn, it's probably nothing.

If I wanted to take the easy way out, I would buy a Euro car, those are cheap to hop up where I stay. Aftermarket support for Honda's is almost non-existent here. If I wanted to take the easiest way out, I would do a B16 swap. But I am not about the easiest way out...

And finally, yes, I think my SOHC is better than many DOHC's. It is better than the DOHC's offered in MANY Toyota's, Mazda's, Nissan's, VW's, Opels, Fords, Hyundai's, etc... Heck, my old D15 was more powerful than some of those... But then again, I don't care what you think because I am not here to impress yor ass, I only care about answering the question asked by the starter of this thread, because I would like to help him... Incidentally, he also only has a single cam and a carb setup, so maybe you should pitch your best insults his way also, he deserves it just like me, seeing as you are the SOHC Carb police...

just admit it , you are a lowballer, you have no money, and you pretend that your little sohc is a good as a dohc. whatever lets u sleep at night buddy.

you know nothing about D series and you probably dont know much about motors, why dont you go read up on D series performance cuz d15 certainly made you his bitch

you come up with nothing but your a cool guy cuz you have a dual cam motor, people who have fast single cams get more respect for doing more with less than those who pay a shop to swap their motor and drive around like cool guys

preach on d15!

so your a 91 si, with a d16z6 that runs what 15's, and u get all the respect because??? if you believe that a D series is better than a B series than i dont see any reason to argue with you. i really dont care how well you've built your D series, because i know that a B series will always be better when built, than a D series. maybe some people on this forum "respect" you because your so cool to have a d16z6, but i dont.

Who cares what each other thinks. To each their own, they like the way their cars are setup? Then let them like it. You dont have to cut people down just because the like their SOHC's more than DOHC's. Personally I want a DOHC, but it's not like I hate my stock engine soo bad that I'll run it to hell. Shoot.. Im a student, and frankly money doesnt come easy for me to do mods to my car. The most expensive thing I could ever do is probably put on rims and new tires. Engine's dont seem feasible. So everyone has their own paths to make their cars great. I've started from modding my car's interior, integra console and all. Even audio. This is the 88-91 Civic/CRX forum, not the "MY CAR IS FASTER AND BETTER THAN YOURS FORUM". So just give people their respect for what they've built, and just chill.

I agree fully. All I wanted to do was help Rufes1. I did not want to flame, insult or irritate anyone. I am glad if Optimuscivic enjoys his car, it is a honda afterall. But I am not glad if I get shot down for having a car which is not according to his taste...

But then, I said I do not care, so I should'nt even mention it...

Optimus, it is cool you love your setup, I am happy if you enjoy your car even half as much as I do mine. And if we ever do meet, I will make sure not to race you, because you probably will hand me my ass.

But I bet I can tune carbs better than you...

pull your head out of your ass there buddy, no one said i was cool cuz i had a d16z6, yea so i run 15's so do poeple with b16's, ls's and b20's whats your point i run alittle slower 15 sec pass done with less money, i never said a D was better than a B but people like you who think people are stupid for having a single cam when you know nothing about tuning or getting power out of it

some people like a challenge some like the easy way out, tell me did you do your B swap or did a shop? do you even have a B series? what are the specs on your car please inform me

hi this is a friendly reminder that one, "dissing", making fun of, or directly assualting another member of AF regardless of reason is a direct violation of the user agreement. two, this is straying FAR FAR FAR from the topic at hand. now unless you have more input on performace cams i sugjest we all shut up for now and let people bog the server down with real replies.

now to the topic. honestly man i dont know of many places with performance parts for our years, most parts are made for 92+ but ill ask around and see if i find anything local here in frisco.

[psyfron]

hey there im from aus too...
im in qld if u need any parts ive got heaps... just let me know on msn
[email protected]

im also thinking of doing up the old d15b4...

i cant find any cams either however honda did bring out a vtec d15 and if u can find a motor, swap the head and do a lil wiring and im told you will experience a considerable gain...
the advantage of this is you can keep the carbs if u like them or change to fi from a later model d15??...

im sorta thinking that ill get rid of the standard carbs and see if i can get twin 45mm side draft webbers to fit and an aggro cam... will be a mission though...

As for optimuscivic, he who spends the most money will always win...
so what u want a medal??

vtec is great dont get me wrong but its NOT the b all and end all... its just an aggressive cam profile....
the advantage of carb is that i can have a much more aggro cam than u and i dont need an aftermarket computer to get it to idle...
its all about how much air and fuel u can cram in there...

if u do find anything Rufes1 for this old clunker please let me know...

[Rufes1]

Hey,

Thanks all for your help. Just got back so havent had a chnce to check the thread. Psyfron added you to msn. Will keep an eye out for good cams.

Cheers
