Honda Civic EF bike carb conversion

[@salrivera7578]

Can such set up be made on a d15b2 motor with 2 injections carb on or a weber my have electronic ignition but is a carb with 2 injectors on it they call it for economic purpose is a 1989 crx duel point system I was thinking a mini me set up 10.1 compression but I love carbs with a nice cam for sound and bit of power

[@valentinhisoka5367]

sound is very awesome

[@kentuckyyankee]

Do you know what jet size for a stock 1.8 engine using cbr900 carbs?

[@flecktards3126]

Question for you. What distributor is that?? I run a carbureted converted d15. Modified the DPFI manifold to take a Weber and then I hacked up and an 80s Honda distributor and made an adapter plate. That’s looks like a nice bolt on.

[@bozidarbilusic]

Hitachi D4W88. It’s this car’s original distributor

[@flecktards3126]

@@bozidarbilusic Ha. Thank you so much. I thought my conversion was so genius back when I did it but I was too ignorant to check the EU market. I think I might try one out for another build that my friend and I are putting together.

Hello! Is the d16z6 carb dual new and how much price? 😇

[@brettprisendorf924]

I'm thinking about doing this d16y7. What supporting mods will I need to run a setup like this?

[@bozidarbilusic]

Pretty much none. But it would be nice to have a mechanically “advancable” distributor, which the d16y7 doesn’t have I believe

[@brettprisendorf924]

@@bozidarbilusic awesome! Thanks for the help

[@flecktards3126]

@@brettprisendorf924 I was able to adapt up a 1980s distributor for my d15b2. It’s doable. Vacuumed advance. No ECU.

[@GamerPro-nw5lf]

does the 2007 honda hornet cb600 4-mouth carburetor sold in Brazil, does it work on the gm 153 2.5 engine, from the 4-cylinder Chevrolet Opala, which is basically half of an old gm small block v8 engine?

[@bozidarbilusic]

I don’t see why not :)

[@joeyp5258]

How did you plum up your vacuum ??? I have two vacuum lines on my distributer. Which one did you use ???

[@bozidarbilusic]

You’ll probably want to use the one that makes more advance. If I remember correctly it’s the one closer to the distributor itself, but try it yourself

[@dave_strada]

How much power does this set Up make ?

[@bozidarbilusic]

I never measured, probably some 10hp more. But the throttle response is where you gain something from this conversion

[@falkone8096]

hey if it's not too much trouble is any there chance you could put together a rough parts list? keen to do this on my d15b4 with one of the danst manifolds :))

[@bozidarbilusic]

Hey! It seems like there’s quite a few people interested in doing this so I’ll try to put together a video on how to build soon. Basically it’s manifold and carbs, you don’t need anything else, but it is nice to have a set of jets to tune it properly, some sort of vacuum equalizer and an afr meter

[@falkone8096]

@@bozidarbilusic a how to video would be awesome!! i ended up doing some more research on the parts that ill need and i think ive got it down pat, ive got some zx6r carbs on the way too :)) something roughly step by step would be really helpful as there isnt really anything like it on the internet.. cheeeers

hi I would like to redo this assembly for some time, I would like to know how to change the fuel pump? I intend to take an intake pipe int as well as a carburettor ramp like you, what should I buy in addition?

[@bozidarbilusic]

I used the original fuel pump, but it would be best to use an inline electric fuel pump from motorcycle. If you go for that option then just eliminate the existing one and put the new one as close to tank as you can. If there is anything I can help you with just let me know:)

[@FrBalade13610]

@@bozidarbilusic okay I see! and removing the original pump you have to buy a blanking plate? or do I simply unplug it ?, there is some adaptation to do for the assembly or is it relatively simple?

@@FrBalade13610 You can remove the old pump and make some blanking plate. Its just 2 screws, anyone can make it. That danst kit is a great idea.

@@mb_111_rx2 probably yes. It’s hard to guess, there’s many factors… displacement of the engine is almost twice the size, but the rpm is not. It’s also important what type of air filter you use. It’s hard to tune them without any

[@IsadoreWoW]

Just converted my d16a6 to run r1 carbs, you using ef spark plug wires? My standard ones are really tight using the 2 wire dizzy (cos it’s much taller than injection one)

[@bozidarbilusic]

The ones in video are AliExpress... crap Now I use original ones, but I didn’t change the dizzy so its all fine. How is your setup working? Jet sizes? Pictures? ;)

[@IsadoreWoW]

@@bozidarbilusic mines been running on three cylinders since it’s been done which I think is as a result of cylinder 1 (the longest wire) being waaaaaaaay too tight and stretched at the moment I’ve only changed the main jet to 180, once I have it running on 4 I’ll check timing then use my Aem afr to perfect the jet sizes, I’m assuming I’ll need to go down but loads more to do on the car yet, needs exhaust and throttle cable bracket making

[@3dkiwi920]

Hi there! How do you manage timing with the stock distributor?

[@bozidarbilusic]

Just manifold vacuum ports that connect to a vacuum equaliser bar and straight to a distributor valve. No problems with that

[@3dkiwi920]

@@bozidarbilusic Thank you so much! I really want to pick your brain on this topic if you would let me? So if I use the distributor that came with the engine I have (nzdm d16a7) the vac advance dizzy will have the correct timing already? Even if I'm using a homebuilt manifold? I'll be honest I don't know much about this stuff, and the idea of a vauum line changing the timing confuses me, as I dont know what vacuum cases what timing. My current engine is a jdm d13b which has the dreaded vacuum box of death and a computer controlled pgm-carb, so I want to eliminate the ecu all together. Thanks again and sorry for the wall of text!

[@bozidarbilusic]

@@3dkiwi920 Happy to share what I learned, maybe I should make another, more detailed video... If your ignition timing is ok now, it will most likely remain so after this mod.Once you install this setup, you can set the ignition timing using a timing light by moving your distributor (clockwise to retard). Your D13b2 engine (in original) comes with a vacuum valve that constantly changes the ignition timing by a few degrees depending on a vacuum (duuh) in the intake manifold (hoses number 2 & 5 in the dreaded box). I'm not familiar with the d16a7 engine nor with it's distributor, it might not have that vacuum valve at all. In that case, you can eliminate all the vacuum hoses and have a clean manifold, but it will affect your engine's efficiency a bit, so if it's a daily driven car I would not advise it

[@3dkiwi920]

@@bozidarbilusic OK cool! Yeah the d16a7 is pretty much the same as any other D series but about 9.5:1 and 115 hp, NZ only, it's injected. I can't believe you actually know something about the shitty vacuum box on the d13! ( its a jdm d13b btw, no data on it; not a d13b1 or d13b2) I want to build a daily driver, not looking for power at all, I just know that I dont want an ecu or any of that vacuum/computer carb crap because if it ever breaks I'm screwed; I can't even find info on it in Japanese ( the pgm-carb) I would rebuild the d13, but its very skinny on the bottom end. The car is a JDM E-EF1 23l. I understand timing in principle, how to set and rotate the dizzy to adjust it, but I assumed the vac advance on a carbureted engine would be very important at higher RPM as there is no way to 'set' it like you would electronic ignition; it's on a fixed curve which is unknown to me. Anyway thank you so much for your help, I've been thinking about this for years and it's so hard to find info on; I appreciate ya!

[@bozidarbilusic]

@@3dkiwi920 D13b is a great engine, it's a squared bore/stroke. Just to point your attention, if you can find dual carbs from a 1990 civic, that would be a huge difference in throttle response and power. It was sold in eurepe (ec9, d14a1) and in NZ i believe, in some d15... check it out before you decide

[@drproctologist]

that sounds awesome, EC9 owner here too. all i've done is stick on some 50mm webers which were hard as nails to find. what are the main power gains out of this?

[@bozidarbilusic]

There are some power gains, but it’s highly subjective. I think there’s better potential in those webers if you want power. But yes, you can’t beat the sound 😀
