Ok sorry if this is in the wrong section but im look to purchase headers here soon. Im lookin for good power gain for reasonable price. The engine i have is a d16y8. What headers should i go with? and should it be a 4-2-1 or just a 4-1?


P.S MERRY XMAS =]
 
i prefer 4-2-1 for better clearence
it depends how low you are and the conditions of streets you drive.
but any 4-2-1 or 4-1 you go at a d series you will end up with very good gains !!
 
4-2-1 header mate better low down power.If i were you id look into the likes of 5zigen or as u say dc sports theres a guy on here baz ctr and he should be able to sort you out got me a good deal on my 5zigen b series 4-2-1
 
first this is in the wrong section. we have an exhaust section, i will move the thread for you, second i spent a lot of time tying up an exhaust manifold thread, it is stickied at the top of the exhaust forum, please read it.
 
Dont bother with mods for your d series.

Thats a pretty stupid reply!

D-series engines actually respond to tuning better than B-series as they are not as tuned standard. I had a d15 and it made 134bhp with a cheap airfilter, crap exhaust, decat and an ebay 4-2-1. It was 114bhp standard!

Wow I didnt think they had as much potential:secret:
 
d series are very reliable engines too.
lol i did no service mine since i bought my car and for 2 yrs almost 15-17k !!
the car was still runing fine !
i was planing for the swap for a b18 anyway.
 
Right. I will start with my experience with the D-series in which I modified a D16A6 to be faster than a B16A, easily.

1) 4-2-1 header not 4-1 because they are not high rev engines - 7800 max ok?
2) Bisimoto cam + cam gear (stage 2)
3) Mild port match + smooth the ports
4) 2.25-2.5" exhaust system
5) 4.2 final gear from a D14A Civic the others are crap 3.8s
6) Air filter K&N
7) Carbs - i ran dual carbs from a Concerto with larger jets then finally quad carbs from a ZX1.
8) Pistons from a 1.3 because they are the largest domed OEM pistons which fit.

I made 148WHP with this setup and because it was in an EF weighing 920KG it beat most of the B16's I encountered 0-60. They would catch up in the end but thats well over 90MPH ...that was a lot of fun.

They are packed with potential don't underestimate them. The low end torque sure beats the B16.

Let me help you all here.

D15 - Slow
D16 - Slow
B16 - Slow

Unless you are straping a turbo too it, there is no point modding a dseries engine.

And for the person claiming 134bhp? Is that meant to be impressive lol.

To the original poster, save your money for a b or k series swap
 
the guy may like his car and engine and wants just to free up his intake and exhaust
where is the problem ?

yeah right try to take a turn with a k swap ef-eg-ek ...
you need money to make a swap not only for engine but handeling etc !! alot o money.
 
Why don't you give the original poster a break - there are reasons for keeping the D, money, insurance and others.

134bhp is impressive considering it's non-vtec and began life as a 105bhp. It's the % gain thats pleasing vs money spent on it.


Original poster - Goto www.d-series.org, I believe you get more help there without retarded comments.

There was nothing retarded about my post, and if you want to continue attempting to call me names then PM me eh and stop posting shite.

My point was there is NO point in spending money on an engine for no real gains. D series will always be a low performance, economy engine apart from as iv said turbo'ing it. The money you would spend building a d series engine etc would pay for a simple b series swap most likely.
 
getting back to the point/question, yes the DC 4-2-1 headers are a nice upgrade. I did that exact same on the D16y8 I built up. Very fun engine to tune. pssst, get a hondata, I was able to get an extra 15hp with this one upgrade, almost the price of your DC header too. I would do the hondata first then get the headers...just friendly advice.

DC 4-2-1 headers...:nice: love them and the cost is right on target for a SOHC.

"No real gains" - what % of power gain vs money input would you call worth it? It means all us B-series should dump our cars cos it's flippin difficult to squeeze a further 20hp out of it. Just get a faster car.
Engine swap vs. Modifying D's has been discussed many times already, I have lived it, have you?

Google Bisimoto - you can see the fastest Honda's are D's and not B's.

I think your going a bit too far with this. While i agree that for the most part a d16 does not have much to offer in NA trim that does no mean you cannot find happiness in it and enjoy a car with a mildly built d16.

An engine swap is not an option for everyone, some people just want a little more power and responsiveness and it's not fare for you to tell them otherwise.

Feel free to point out the pro's of a b-series vs a d-series but try to be somewhat polite about it, you have to realize at this point your advise was not asked for so if your going to offer it be polite about it. The thread was asking what header was better, not if it's "worth doing".

Plenty of people are happy with there single cam motors. Don't get me wrong i have a turbo B myself, but everybody has the right to enjoy there car with the motor they chose to modify.
 
Get a Megan Racing header. They are the same as DC but cheaper.

Not impressive as in alot of power but impressive to get 20hp from those simple cheap mods!

I can also say that I have had my old 205bhp dc2 on the track and have also been in a wee d15 civic with minor breathing mods, cut slicks and completely stripped on the same track and it was just as good fun. The wee civic was just under 2secs in a 1.15 lap slower than clio 197s

Make of it what you want but its not an argument about who has the most horsepower!
