- So today we are going to find out the bike carb Toyota MR2 aw11 4age mpg! In other words we are going to find out exactly how much the MPG worsens when you do a bike carb conversion on a car engine!
So how do we do it? We remember that road trip I took just 2 days ago? That was just the opprtunity needed to collect some valuable data on the MPG of the bike carb 4AGE.
When I started out that road trip I filled up my gas tank all the way to it's maximum capacity and recorded the number on my odometer. I then went on the road trip, and drove the mr2 until I depleted about half of the gas tank. I then went to a gas station again and filled up the gas tank all the way to the top again. I recorded the number on my odometer again and I recorded the number of liters of fuel I managed to fit into my gas tank.
This gave me the distance I traveled and the exact amount of fuel the engine consumed during that distance. This enabled me to calculate my fuel consumption in liters / 100 km, which I can easily turn into MPG.
And here's something even better. I actually drove this same route with my stock 4age rebuild 2 years ago and recorded the MPG back then as well so we can compare the bike carb mpg vs the stock 4age mpg. Hip hip.....

10,5l/100km is quite nice result, not that much really for pretty agressive driving. As for an 1.6l engine it's nice result for that gain of power.
Drowzee :)
I built only two engines in my short life, a 1330cc A series engine for my mini and an M10B18 for my E30. My mini got better MPG after building, I went from 9.4:1 go 11:1 CR and from 244° cam to 268° so still fairly reasonable. The M10 engine also did better, with higher CR too and 286° cam, as well as better tuned advance. Indeed, when driving you need less throttle for the same power and the higher CR, and tighter timing makes for better MPG, better noise and better power when needed ;)
Pozdrav iz Banja Luke, slucajno sam naletio na kanal, svaka cast za kola i za trud! Samo jako!
Pozdrav! Hvala na podršci!
Wow. That's not that bad. Love your videos.
You are crazy mate! You did this road trip so many times... To be honest I was expecting to be worst economy, however building a performance car is not about economy, it is about mesmerizing soundtrack and thrilling moments! Hahahahaah
Exactly! Amen to that.
Nice numbers! My moms automatic Golf does around 9l/100km when driving like a (grand)ma so its not that bad.
Another thing I do to keep the numbers right is to fill the tank at the same pump.
Most of them here are at an angle, so some of the pumps don't let you to fill the tank all the way due to some trapped air in the tank.
Once time i had 5,5l/100km and a pump later I had 8l/100km when mostly it is around 6,8l/100km.
Grandma driving isn't good neither for high revving engine nor for your sanity :p
Yeah definitely, I'm never doing that again.
Grandma driving is awesome. I have a supercharged coyote mustang, that rarely leaves the garage because it eats tires (4th set of tires in 17k miles), and I drive it like a grandma 90% of the time... that last 10% is why I own that car though... Every time it's like, "oooohkay, now I remember why I sold the ex wife's car and bought the blower with the money".
@@dre04mach grandma driving causes wear in cylinder liners as well as on piston skirts
Nice information know i even more want ITB's in my car
At the beginning of last July, I did another round trip from Vancouver Canada to Bay Area California with my Toyota Corolla (purchased brand new in May of 2006).
This is common North American model with 1.8 Liter 1ZZ-FE engine and not that common 5-speed manual transaxle and 164 036 km on the odometer.
I did 3 565.9 Kilometers (2 213.5 Miles). For the whole trip, I used 219.2 Liters or 57.9 Gallons of Regular Unleaded fuel. My total fuel consumption was 6.155 L/100 km or 38.2 MPG US.
It was very hot during my trip so I used the air conditioner most of the time. I'm going again to California at the end of September and I'm expecting even better fuel consumption, below 6 L/100 km (40 MPG U.S.).
Prior to my trip, I made 1566.8 kilometers since I did last oil and oil filter change. When I came home I replaced oil right away. That was 5 132.7 km (3190 Miles) altogether and engine consumed only 100 Milliliters of oil.
That's Toyota quality right there, the 1zzge is a great engine.
I had done a lot of performance upgrades on my '86 AW11; TRD headers and exhaust, K&N intake, ignition upgrades, and a few more things...with tons of suspension upgrades. I averaged 28 mpg in the city. Some performance upgrades improve mileage, many reduce mileage.
28mpg city is impressive!
@@d4a Tire pressure is a bigger factor in mpg than some realize...and weight of the car. I had stripped most of the unimportant stuff out of the car. No stock air conditioner. No power windows or locks. Had to have a potent stereo system though...tunes are mandatory! Sure wish my current car got 28mpg...but it is an Infiniti with all the fancy stuff in it, and a massive stereo system. Cheers man!
Grand Daddy D4A laying some knowledge on us over here in his lawn chair.
That's awesome. With my 2.0l Alfa 156 I get ~11l/100km with my normal driving and around 9 when driving a bit more consciously. Just like yours it really is quite hard not to drive hard lol
I love the 156. I almost traded my first car for it, but the dude wanted more money than I had. I was sad :)
Stock 156 ts?
My Blacktop will do around 40mpg with the air box on cruising 65-70mpg on the highway in a pretty stripped down 85 mr2. Open throttles and I'm on it in canyon it's getting around 15mpg. This is on 91 octane stock ecu
I don't even see 40mpg on my 2008 Auris!!! My standard/tired Mk1 is probably doing 17-18, lol.
Hey if you want power you def lose your MPG.
Stock 4AGE 16V Blue top have around 112 to 118 crank horsepower.
With your bike carb and cams, you gain more top end and now the engine is not restricted of air on the top end and pull more power thru the rev range.
An un restricted exhaust will net more horsepower but your ears will be deaf from all the exhaust noise.
Still impressive for an almost 26 year old engine to have that decent MPG.
My thoughts exactly. HP has to come from somewhere. :P
@@mrsabidji i always lol at those who ask if there is a way to gain horsepower while keeping his MPG.
There is no free lunch
@@linchester8464 Well, there are ways to get a little bit of power here and there without ruining fuel economy, but it's always a compromise and if you want the biggest numbers on the dyno, the mpg will definitely suffer. :)
Hey I'm new to watching your channel. I like the content. I'm wanting to do the same with my Carbureted Nissan GA15DS.
Welcome aboard :) sounds like a cool project, the GA15 and 16 are cool little engines, good luck!
I'm planning to do 1100cc motorbike carbs on my Lada 1600, at a later date,they cost around 150e in Serbia,and i hooope i will get below 12l/100km xD Anyways,that engine of yours,for how old it is, it's got REALLY good MPGs :D Keep it up,love the work! I've gotta meet you once in my lifetime :D
Thanks man, we'll meet for sure, we're neighbors after all. I'm actually curious about Ladas. Which bike are the carbs from?
L3ks4 Hey, I'm from Bulgaria and also have Bike carbs on my Lada. They work pretty well, but once you put a sports camshaft your fuel economy at lower rpm goes out the window....
Vasilian Sotirov Aaah okay! Thanks for the info, i don't really care much about fuel economy since it'll be a sunday cruise/showcar, but thanks for the info! What power have you got with those upgrades?
These are not the only upgrades in the engine. It's 1.8 with ported head, biggest possible valves, and higher compression ratio. The camshaft is 316 degrees. It's still on the stock exhaust headers, which restrict power, but I can say about 120 hp. You can message me in Facebook.
Someone help me! All I want to do is get a modern bike carb to replace an old carb that is impossible to get missing parts for. I was given a FREE = ( Honda CM250. It has twin cylinder running off one carb. Part 16100-KB4-672. All I want is a NEW carb that works and gets me from A to B. Is there a conversion algorithm like i saw for cars? Why can I not find any info on a simple carb to carb transition? Post a link or something. Thank you.
Love your videos, and all the info. I have a question for you. I have a 1990 4age small port I'm thinking of hanging a set of bike carbs on, my question to you is: was it as simple as buying the bike carb set up from danst (along with a nodiz) and turning the key. Our did you struggle with adjustments? I guess I have two questions: and in hind sight would you do the throttle bodies instead? Your thoughts are greatly appreciated, as you have put countless hours in perfecting this engine. Thanks
The reason why I made all my videos is precisely to answer questions like that. I have a video on absolutely everything I did in the process that was relevant. From unboxing danst parts, the fuel supply, balancing the carbs, ignition maps, jetting, carb cleaning, troubleshooting. I even made videos with quizzes in them to help you decide whether you should or shouldn't do a bike carb conversion, along with my thoughts on the matter. So really, it's all in there. It will take you two minutes browsing through my videos to find it all.
Ok, sorry didn't see them all, saw quite a bit but not the process of adjusting and balancing the carb set up. I will browse your video library and find the ones that cover my question. Thanks
man i realise now my gf's turbodiesel 1.9 ibiza has REALLY good mileage. It almost never goes upper than 5l/100km and can dip even lower if you grandma-drive it.
ouch I really thought it might have been better than that, I get about the 10L/100km in my 5.7L Calais now(Australia), owned an AE86 (before they cost a $bazzilion) years ago and it was somewhere around the 6L/100km
For a comparison a 2014 Fusion (see Mondeo) 1.6l ecoboost got 23.5mpg with a 6 speed atx. Driving it briskly most places.
Hmmm wonder why it's so bad that's a really nice modern engine. You're probably stuck in traffic often?
@@d4a those Ecoboost arent that Eco imo. The turbocharged nature = more fuel than NA
Well it's either stuck in traffic or moving out. No real in between. Now a 2.5l NA Fusion , returned 26.5 at it's worst same driving style, was faster, way more responsive and fun to throw around. If you have any Fusion/Mondeo put it in S it will get better gas mileage and be ready, otherwise they feel unnaturally slow due to drive by wire holding everything back. Smaller engine does not automatically mean better fuel economy. No nothing anti-car people should have nothing to do with making cars or engines. Their assumptions make things worse.
That last sentence tho! :)
Why would you want to be at 13:1
AFR at idle? Shouldn’t you shoot for stoich (14.8:1) at idle and low rpm cruising? That’s where an EFI car would be. Does this have something to do with carburetors?
In theory carbs can idle at 14 or so, but they usually run very poorly. They can cruise at 14 ish, but I liked the way richer afr performed.
@@d4a
That’s really interesting. I never knew that. Thank you for answering.
I didnt think you would get so good L/klm with those bike carb... 10.5L/100 klm is pretty good; What I want to know is What's the L/100klm in heavy trafic ?
Hmm I haven't calculated in heavy traffic, but it's pretty horrible probably. Around 12-13 liters likely as it idles at 1000rpm. But this isn't my daily driver so I always avoid heavy traffic :)
driving 4 answers Ok, Thanks for the answer ! 👍
TRASH! Start over. Honda swap!
Kidding. Glad you have been getting to drive a lot. :)
Lol. Yeah, it only took me almost 5 damn years. But it was worth it. This is also the first time I'm actually looking forward to winter, the mr2 will be resting without a mile long list of to do things and I'll get to enjoy working on my first bike :)
US gallon or imperial?
I don't know honestly. I just went for the first Google result for "convert liter/100km to mpg". I think it's us gallon probably.
@@d4a Ok so ~27 mpg Imperial.
Not that bad for a sporty car.
My toyota 2e engine can spend 6.5l/100km
Pretty impressive, I've only managed about 8.5l from my 2e, though I find it hard to drive economically lol
on a bike carb?
First Cheers mate :P
Yo!
