i need to know how many of you would be interested in a header system for the D17A1 honda civic LX? you can reply here or at my e-mail dan@bendixmotors.com . i am planing on manufactoring such a system.

Let me know,

Dr. Speedy

 

what background do you have

 

i am entering my junior year of college and my degree is mechanical engineering. i also have been working on cars since i was 18 in the professional field.

 

What for? Even if you made one with an elaborate bend structure, like a Bisimoto header, you still won't see 5hp at the wheels. Hardly worth the price of building it.

 

well it is worth a try. they have every thing else for the lx but a header. and any basic tuner knows that a performance header allows more flow and will hold up better any more mod that at tuner might do to the block, but as far as the horse power gain all headers will only give you between 5 -10 horses at the wheels. the basic job of a header and exhaust system is to free up anything causing back pressure, such as the Catalytic Converter.

Cadillac converter?

LMAO

It's illegal to drive without a catalytic converter, here in Wisconsin. So, I guess if you could figure out a way to design an elaborate Bisimoto style header, with a 2.5 - 2.75" catalytic converter attached afterwards, then I'd say you'd be one hot ticket item for the LX's, and most likely the EX's as well. Considering the best options we have available, are just standard 4-1 headers, it'd be nice to see something with a little more time behind it's overall design. If you haven't seen Bisimoto's header, I'll leave you with a picture. Keep in mind, that this header has produced the largest amount of hp for any header in the D-series realm.

 

as log as you have one catalytic converter you are ok bythe law. now you can put it after the header system , on the exhaust system. i will no more by tommarow, for tonight i will looks at my friends LX. thanks thought , i got that part covered, my wife is a cop.

 

haha im running cat-less for the time being but dont need inspecion sticker for almost 7 months - so ill stick a cat in there sometime before than

 

for the price / performance of the Kamikaze LX header i doubt u will compare.

its made ONLY for the LX/DX engines, provides 2.5" collector, and has excellent bends/welds.

Im not trying to bash u, but this header is the best one u can make for any d17, and even if you make a fantastic header for the d17, it will only get mabye 1-2 hp more than the kami, and for the extra $$ of a custom job, it wont be worth it.

 

I highly doubt that a standard 4-1 header will produce the highest gains for a D17. Especially since it hasn't in the past. I think if you were to look at the history of D-series Headers and compare numbers, the 4-1 was actually on the lower end of the spectrum. Going un-traditional with the pipe layout would produce better gains, as long as the flow model was kept at a desired flow. Hence, why I mentioned the Bisimoto.

 

thank you for the advice, but i already desided to go with the Bisimoto header system.

I agree with parts. IMO 4-1 &gt; 4-2-1 on any engine, but all depends what your going for in terms of power.

I meant that right now, the 4-1 Kami IMO is the best header out their, cause its the only 1 that can supply our d17 with a 2.5" collector.

Any header he would make would cost a lot more, and not be worth the small gains it would accomplish over the Kami, or any other header for that matter.

 

i plan on manufacturing header for the lx, but I will look into the kami header and see what they have to offer.

Well, the 4-1 is good on some accounts, but it all depends on what you're going for. The 2.5" collector, although the only of it's kind, isn't exactly a selling point I'd look at, since it's a little large for the amount of air flow that's going through a stock D17. If you had some modification to the internals, and possibly more compression, then I'd say a 2.5" collector would be beneficial. But, in stock outfit, it wouldn't provide much help, if any.

Take a look at that site I listed, for inspiration.

 

very nice webpage, nice to see such an extensive review of different header styles

 

thank you, i have anthor one that will be comeing out in the begging of july

 

make stuff for the k20a2, i'm sure you'll have more success.

That's what I said when I first saw it.

And, I don't know if you've been there or not, drspeedy, but http://www.d-series.org/ is a great place to start looking for information about D-Series part manufacturing. Those guys have a vast knowledge on the engine.
