Pretty complicated when you're already EFI, but if only carbureted it's a very easy swap, just need to order parts, sort out how to have the intake+airbox, and then jet/tune.
If you connect vacuum line from the advancer directly to intake manifold without reducing vacuum force, it'll rip the diaphragm apart, the vacuum should come from carburetor (with calibrated orifice)... happened on my advancer on 3A... ))

Hello. A reminder. Vacuum advance port on distributors DO NOT go to manifold vacuum source. It WILL be over advanced. Plug port and adjust for full advance recommend for engine.
That's how it's works on every old carbureated V8 engine I've seen... You can do it either way..manifold or a throttle vacuum... I prefer manifold... vacuum advance is only for street use anyway.... in racing it is not required...
I was thinking about doing this to a Civic engine.. D series ... The ones from Japan were dual carbureated quite longer than they were here in the States.... I got my hands on a intake manifold and a set of those carburetors unfortunately the carburetors were junk...but I still have the dual carb intake manifold for a D series and I have a bucket of carburetors side draft style that would work with it....👍👍👍
Same here in the UK, we had the dual carb civic into the 90s on the 4th gen Civics, I turbo'd mine while retaining the carbs (Spoiler alert: it didn't last long, but that was more related to the (lack of) spark control rather than the carbs themselves)
First time I've heard about needing to change the fuel pump. Currently looking into itb conversions and none of the research that I've found have mentioned this. Also regarding the MAF sensor, if you fabricate a plenum you can chuck the MAF on that and should be good to go. At least this is from what I've read.
Thanks for all your vids i've been watching for so long, but now trying to figure 2 projects options : - Triumph 2000 mk2 6 in line with SU carbs to 2 ramps from 3 cylinders Triumph bikes + 2 fuel pumps (1/ ramp) + hose to genuine ignition sensor canister - the other would be on a Audi 90 quattro 2.2l 5 in line with the old K-jetronic system, but might be too complicated Thanks if you have advises
Wow thanks!!! Awesome. But what about MAF intake sensor? Like on a 2007 yaris 1.5L? Mass air flow sensor does not seem to be useable or maybe hard to replace. Thanks!
it's 7am and I'm watching this with my brain not following anything he says, fuckin seems like a lot for some itb's lol pretty sure you can just install it without having to change map sensors or fuel pumps or anything like that it'll just run like crap on cold start (it'll want to stall so you got to keep giving it gas) then once it's warmed up idles perfectly stable at 1k
i have think about it. and i see lose one carb 42mm good for 550cc singel cylinder what stop me to use 4x 42mm carb .? cost about 40 euro for one carb.
Can this only be done on an engine which uses a distributor? I am interested in doing this to my 1st gen 1zz, which uses a map sensor but 2 coil packs for spark
im planning on slap itbs on my 1.8 20v turbo, i know that if i stick with the single 58mm trottle i can generate up to 600+hp without problem, so how can i calculate de diameter of ITBs to be at least equivalent to the oem 58mm single body?

hi can you guide me to get best bike carburator in my mitsubishi galant 96 7Gen 2.0 and its already carb from the factory. i am really interested to convert my carb engine to bike engine. and looks good if you pop the hood kinda clean and sporty looks
Hey D4A. I've a Toyota TE71 Liftback and it has the well known 2T 1.6L single carb engine, recently my father gave me some working carbs from a Honda cb750 four-k and an electric fuel pump. However, I've some doubts about which main jets I should get since these carbs are completely mechanical and they have the guillotine system, so the throtle response is theorically pretty fast and I can't afford to screw up a recently built engine from the ground up hah Cheers from south america, keep that MR2 rocking!
That's a very tough question. I assume you're talking about carbs that have flat slides? They are on the tricky side when it comes to tuning. But if you have a fully rebuilt engine I suggest an additional investment of 160$ into an AEM x series gauge that's gonna make tuning a lot simpler and definitely prevent you from blowing an engine. Here's an unboxing video: ruclips.net/video/6_PWA4DhFkk/видео.html And here's an install video: ruclips.net/video/K-nWZcjfaos/видео.html
@@d4a Yup they're flat slides carbs, I also have vacuum meters but it didn't come to my mind that a wideband was a must thing to have. But oh well such engines turn out beautifully so it'll be worth it to spend some $ in a wideband and plenty of time at tuning the carbs, thanks for the heads up man!
Hey, was wondering you did for your PCV system? I've been trying to connect all my parts but realized I wouldn't have the usual inlet to the manifold that would allow for vaccum to the intake manifold before the butterflies.
If we have maf sensor so why we need standalone ecu for spark advance.? So when we have maf sensor or carburetor with tp sensor so why should we need standalone ecu and convert into a map sensor systems for spark advance..???
Nice I was thinking hooking up my d15 crx honda with a z6 d16 head nice cam etc and I was thinking of the mikuni carbs well bike carb and I wonder if you can help me with information how to install etc the motorbike carbs thanks
Greetings from Colombia. I've been watching your videos like a guide to do this to my already carb toyota 4k engine, but want it a little bit better, so I have a little question, in the making of the intake manifold, the vacum line for the boster should I take it from all the tubes, or only one is good enough? also, should I leave the original fuel pump? I'm using cbr 600 f3 carbs. Thanks for your time.
Original pump is likely ok if pressure is around 2-4 psi. I used two runners/ tubes for the brake booster. A lot of people use just one and say it's ok.
No it's the same. By the time u buy a hyper Pak or mod dizzy. An mod motor to suit carbs ...u may aswell look for after market ecu. An quads. If you get shit cheap an free costs vary. But this guy wasted his time bet my injected 4age would piss all over this. Just stay tvis that's my opinion spend ya money other places... Extractors ..flywheel . Cold intake. Msd. Ignition.
In a "bangs for your buck and effort" comparison there's also the 2AR-FE to consider. Google "2AR--FE, Spyderchat and Frankenstein motorworks" and you should find a dyno overlay comparing 4AGE's, 2ZZ-GE and 2AR-FE. There's also info on the weight penalty of the upgraded axles and gearboxes.
Everybody's fast behind a keyboard son and can "piss" all over anything. I hope whatever is causing you to belittle someone else's work and make untrue statements soon stops, and things improve for you. But just to set things straight. Megasquirt is 900$. That's without itbs, manifold etc. Everything for a bike carb conversion including carbs, manifold, and Nodiz pro ecu was 950$. That's twice as cheap.
The 4agze is definitely not the best candidate for this. I think you might be able to make it all physically fit but I doubt it's worth it. It would require an immense amount of fabrication, tuning would be a nightmare and it would end up costing more than is sensible. You could just remove the supercharger and do the carbs as on an NA engine but that's stupid too because the supercharged 4age has lower compression compared to NA (different pistons) and the end result would be likely very disappointing. Why not keep it supercharged? If you wanna do this get a NA 4age and start with that instead?
@@d4a I like the supercharger, i was wondering if this could of added the increased response and better sound but now i know to do this on a NA engine. Great videos you got since I Daily my mr2 and not too many people give me mr2 related repair tutorials.
Most carbs are designed to work between 0 positive pressure and vacuum. Reverse the pressure and the spindle seals will generally blow by and leak. The jet size and resulting mixtures are tuned around that max 0-1 atm differential. Cars like the Lotus Esprit turbo enclosed the carbies in a box that was at manifold pressure as a fix. It wasn't a well regarded setup vrs the EFI that replaced it. Almost all the production car carby and boost setups are "suck through" not "blow into" arrangements for this reason. EFI ITB's and boost were used on the RB26 and SR20DET GTiR engines. Look these up in the forums and compare them to the RB25DET and SR20DET RWD variants which were single throttle body. The dyno charts and factory service manuals are all online so you can see what hardware was needed and how they compared.
Hmm.. 37mm should be ok. 39 or 40 will likely be OK too. Gains are relative to other mods and can be from 0-20hp, you can even loose hp of course, if you do it wrong :)
hey man .. I found a set of carbs from yamaha 600 ... their intern diameter is 27mm .. and I want to use them for daily driving a bmw m10 1.8L engine ... factory carburated 90hp motor... I am not looking for drastic HP increase) ... just daily driveablity ... my question is ) .. 27mm is enough diameter ?) .... would appreciate your response
@@d4a there are weights. Kinda like centrifugal clutch. Weights are connected by springs and are connected to a disk, that moves when the weights are flung outwards and that disk advances timing
Hey I'm planning on putting bike carbs on a 4ac 1.6L it has a mechanical fuel pump (powered by the camshaft) would I have to do anything to the fuel system or should it alright, also would Yamaha r1 carburetors be good for it?
very nice project . you connected the tps from the carbs on mr2 cable right? and what about with ecu? did you remap it before use the nodiz ecu? Τέλος συζήτησης Γράψτε ένα μήνυμα...
The tps on the carbs is connected to the Nodiz ignition ECU. The ECU has a basemap, it's enough for starters, but I tuned it later. Here's the ignition map video: ruclips.net/video/d34VE-DrjAQ/видео.html
Best thing to do is caluclate how many CFMs each cylinder will move then get the appropriate carb set to serve that, coincidentally the CFM count roughly translates to the carb bore diameter = 34cfm per cylinder would work great with a 34mm carb per cylinder for instance.
According to him no... he is running carbs of a 600cc bike for à 1600cc car. Personally I would go by hole diameters. Measure intake dia. And try to find a set of carbs with same-ish diameters.
I have velocity stacks. Factory airbox and restrictive air filter are not necessary. Sure, some carbs need them more than others, but usually it only really influences idle quality and very light throttle, both which you can easily correct with proper jetting and ignition timing corrections.
@@d4a is that due to the fact of in this case you have more mass airflow through the carbs instead of the factory application? Only asking because in my experience with cv carbs on bikes without the proper airbox the bike will idle but the smallest amount of throttle it will bog because the needle and slide wont lift due to what im assuming is turbulent flow across the inlet of the carb ?
Thanks for your video . appreciate that , Need your Attention and guidance please , I have Suzuki 796CC 87 Model Made in japan, with company fitted Carburetor, I have installed Honda 125CC carb into that vehicle , , when I have started its engine , engine is running at high speed with out accelerator ( not at normal engine running speed) Secondly Is Fuel pump is the cause , because its supplying more fuel and bike crab consuming less fuel .Please guide if you have
The fuel pump is likely not the problem because as you say the vehicle (is it a bike or a car?) was carbureted before, so likely the fuel pump isn't creating too much pressure. Did you check your throttle cable? Is there a way to adjust idle speed on that carburetor?
@@d4a thanks for reply and time . Yeah its car make suzuki , and I am trying to install bike carburetor in that car which carburetor power is 125 cc. I was think that might be its due to fuel pump but as you said its not thr fuel pump .

Hay bud I'm looking in to doing my own DIY bike carb conversation on an old L28 and a 5m ge I just have sitting in my shop for my drift car project. Do you have any sizing advice or carbs your recommend for that dive engine. They are roughly 460 cc per cylinder. So I'm thinking of using 6 Polaris 500 ATV carbs they are dirt cheap and roughly the right size . What do you think ?
answers yes but i have done it before for 3 carbs so its just doubling down. And I'm a custom and restorations guy . so build it your self is my business. Will the nodiz ecu do a inline 6.
You start out with something and go a size up if it's lean and a size down if it's rich. The process is made much easier with an afr gauge.

This video has inspired me to install bike carbs on my carby 1984, I found 2003 r6 (fuel injected listed on the ad) carbs which has confused me a little. Does it matter what year carbs or would I need to get older carbs ? Can you please help
You don't need older carbs, newer are actually often better because they also have a tps, which enables you to have 3d ignition maps. I think the 2003 r6 got fuel injection, so it doesn't have carbs at all, but fuel injected throttle bodies.
@@d4a I have a 1984 carb honda civic would it be pretty simple to do or would I have to heaps of mods ie 3d ignition maps etc etc . Thanks for your help I really appreciate it
I did make more power, but that's because I raised compression, upgrades cams etc. Carbs themselves won't make power unless the stock EFI is very restrictive. They will however change the power band, throttle response and sound.
@@d4a Oooh, I wasn't serious about the conversion. Neil Jones is a great source for MR2 bits, I learned recently my windscreen seal needs redoing and that is also where water is getting in. Great video on the carb conversion though, keep up the good work xD
I might be wrong, but the way I understand this is to look for a bike engine about half the size. So for you something in 900cc to 1100cc range. Bike carbs take in more air from what I have been told, about twice as much. Anything bigger could be too much carb(s) depending on application of course.
Perks of never sleeping include being up when your new videos come out.

So... older style sport bike has no tps sensor ? I can get any bike list u made but one has sensor or without right ?
Yes, older bikes from the 80s and early 90s usually don't have tps which means no 3d ignition maps. Most bike carbs from late 90s and 00s have tps

Could have used the remaining time to say what to do If the distribuitor has a electronic sensor instead of a vaccum capsule 😄.
any recommended carb for 2e engine? i wanted to spice it up a bit but im new to the platform
Might be a little late to comment but um, the link for the guy who made your bike carbs is not in the description

Would 450cc bike carbs work for a 1.5L inline 4?
Hey I'm planning on putting bike carbs on a 4ac 1.6L it has a mechanical fuel pump (powered by the camshaft) would I have to do anything to the fuel system or should it alright, also would Yamaha r1 carburetors be good for it?
It should be ok, but add a fuel pressure gauge so you can check the psi is within and range the carbs are happy with
Do you need a balancing bar for vacuum advance?
Hi Amigo! What if my car (carb 1.6 82' accord) has an adapted electronic Fuel Pump. IT makes a similar sound of the one on the video.
If the pressure is 2-3 psi you can use it.
very nice project . you connected the tps from the carbs on mr2 cable right? and what about with ecu? did you remap it before use the nodiz ecu?

The tps on the carbs is connected to the Nodiz ignition ECU. The ECU has a basemap, it's enough for starters, but I tuned it later. Here's the ignition map video: ruclips.net/video/d34VE-DrjAQ/видео.html
How bad did the fuel consumption get ?
But, but... my 1984 ford laser 1.5 litre doesn't have any of that..
Im a bit lost 😭
Rodijak....dal se diraju dizne i tko to može naštelat tj dal ima neka formula.....
Do you guys know if this conversion would be basically the same if going with Weber carbs instead?
yes, if your talking twin 40's.
Can I fit carburator in honda civic
I got 1.0L 4 cyl, which carbs size would u suggest for me? If one carb for each cyl
Best thing to do is caluclate how many CFMs each cylinder will move then get the appropriate carb set to serve that, coincidentally the CFM count roughly translates to the carb bore diameter = 34cfm per cylinder would work great with a 34mm carb per cylinder for instance.
hi! if you got a 1600 cc engine you need a 1600cc bike engine carb? no?
According to him no... he is running carbs of a 600cc bike for à 1600cc car. Personally I would go by hole diameters. Measure intake dia. And try to find a set of carbs with same-ish diameters.
Has anyone tried this on the 4AF/4AFE/7AFE ?
how did you manage to get cv carbs to work without the factory airbox from the bike and or velocity stacks and a restrictive airfilter ?
I have velocity stacks. Factory airbox and restrictive air filter are not necessary. Sure, some carbs need them more than others, but usually it only really influences idle quality and very light throttle, both which you can easily correct with proper jetting and ignition timing corrections.
@@d4a is that due to the fact of in this case you have more mass airflow through the carbs instead of the factory application? Only asking because in my experience with cv carbs on bikes without the proper airbox the bike will idle but the smallest amount of throttle it will bog because the needle and slide wont lift due to what im assuming is turbulent flow across the inlet of the carb ?
Now, it sounds like an Alfa Romeo DOHC engine.
Hi mate, I got mazda familia 1.3cc carburator engine. Can u recommend me
Thanks for your video . appreciate that , Need your Attention and guidance please , I have Suzuki 796CC 87 Model Made in japan, with company fitted Carburetor, I have installed Honda 125CC carb into that vehicle , , when I have started its engine , engine is running at high speed with out accelerator ( not at normal engine running speed) Secondly Is Fuel pump is the cause , because its supplying more fuel and bike crab consuming less fuel .Please guide if you have
The fuel pump is likely not the problem because as you say the vehicle (is it a bike or a car?) was carbureted before, so likely the fuel pump isn't creating too much pressure. Did you check your throttle cable? Is there a way to adjust idle speed on that carburetor?
@@d4a thanks for reply and time .
Yeah its car make suzuki , and I am trying to install bike carburetor in that car which carburetor power is 125 cc.
I was think that might be its due to fuel pump but as you said its not thr fuel pump . Yeah one idel setting screw type button available to increase & reduce speed from carburetor , I have try to press around the clock and vic versa but car engine is switching off .
Can I have your whatsaap number so I can send you pictures and videos of my car engine for batter understanding, please

Hay bud I'm looking in to doing my own DIY bike carb conversation on an old L28 and a 5m ge I just have sitting in my shop for my drift car project. Do you have any sizing advice or carbs your recommend for that dive engine. They are roughly 460 cc per cylinder. So I'm thinking of using 6 Polaris 500 ATV carbs they are dirt cheap and roughly the right size . What do you think ?
Making the throttle linkage will be a nightmare?
answers yes but i have done it before for 3 carbs so its just doubling down. And I'm a custom and restorations guy . so build it your self is my business. Will the nodiz ecu do a inline 6.
How do you determine jet sizes?
You start out with something and go a size up if it's lean and a size down if it's rich. The process is made much easier with an afr gauge. Here's a video on installing jets: ruclips.net/video/QwbZ6_46oC8/видео.html and here's a video on installing an afr gauge: ruclips.net/video/K-nWZcjfaos/видео.html
Can you fit bike carbs to a 1-l Ecoboost Ford Fiesta
No mate
What happens to the throttle position sensor if ur installing on a carby model car sorry ? Or can ya get bike carbies without sensors
If you'll be relying of vacuum advance for ignition timing you either just ignore the sensor or get bike carbs without one, plenty of those out there.
driving 4 answers legend thanx buddy
driving 4 answers if u could be little more specific I’d be forever grateful, I have an 81 4g52 carb model , what bike carb setup should I be looking for please
This video has inspired me to install bike carbs on my carby 1984, I found 2003 r6 (fuel injected listed on the ad) carbs which has confused me a little. Does it matter what year carbs or would I need to get older carbs ? Can you please help
You don't need older carbs, newer are actually often better because they also have a tps, which enables you to have 3d ignition maps. I think the 2003 r6 got fuel injection, so it doesn't have carbs at all, but fuel injected throttle bodies.
@@d4a I have a 1984 carb honda civic would it be pretty simple to do or would I have to heaps of mods ie 3d ignition maps etc etc . Thanks for your help I really appreciate it
@ so I will just need the carbs, a manifold with some silicon hoses or a custom, vac lines, some tapping and a tune?? Thanks again
@@hassanreshat7447 i would think it would be as simple as making the intake manifold, connecting the carbs and adjusting the air to fuel ratio
@ champion many thanks for your help
Did you make more power with the bike carb setup?
I did make more power, but that's because I raised compression, upgrades cams etc. Carbs themselves won't make power unless the stock EFI is very restrictive. They will however change the power band, throttle response and sound.
1:16 Where is this? Looks beautiful
Do you know of a source for manifolds in the US?
"Link is in the description." Yet, link is not in the description.
Please give us a 5min t-bar/tin-top conversion? I'm tired of my t-bar leaking on me.
Why not get the t top seals from twosrus or neil jones? It's a shame to convert the t tops into a tin top if you ask me.
@@d4a Oooh, I wasn't serious about the conversion. Neil Jones is a great source for MR2 bits, I learned recently my windscreen seal needs redoing and that is also where water is getting in. Great video on the carb conversion though, keep up the good work xD
does it work for a automatic 2.0 engine
Sure, why not.
You'd have more fun with the car doing a manual swap first.
I got a 2.0l 8v sohc mk4 golf. So would I just look for 2l bike carbs?
I might be wrong, but the way I understand this is to look for a bike engine about half the size. So for you something in 900cc to 1100cc range.
Bike carbs take in more air from what I have been told, about twice as much.
Anything bigger could be too much carb(s) depending on application of course.
@@LarryisControversial3000 thank you.
@@Winterstormadvisory welcome
which bike carbs can fit a 2000cc engine?
40mm ones should be fine. R1 or something like that.
aba carb swap time lol
