Everything you wanted to know about my bike carb 4age engine

[@cocoloco1994]

Nice build, im always been fascinated by 4age engine.16v or 20v, you know its a 4age when you hear its unique sound coming from the ITB's ,well in your case from carburetors with velocity stacks.

[@jhuntosgarage]

I'm not sold on the carbs yet. It will be interesting to see how they work out. Thanks for sharing.

[@Darumacandy]

D4A is pioneering the bike carb conversion, get ready for mazda to adopt it into their new crossovers

[@efx-mj8me]

After driving old carburated cars and eventually moving up to my 85 FI MR2 there's no way in hell I'm going back to that technology. Couldn't go through large puddles without killing the damn engine. Lol. But I still enjoy the channel.

Like someone else said. You trapped me! I immediately sub after the "funky 4AGE build". I love how you answer all the question. Your going to be big man! keep up the good work.

[@Ricerguy]

fun build! will stay tuned. i ditched my bike carbs (fj1100) for bike itbs (yamaha r6 2003/4) because the bike carbs were too pricey to maintain/refurbish, and the bike itbs were cheap as chips + i can tune on the fly instead of disassembling everytime. :)

[@d4a]

Ricerguy Hmmm. Sounds tempting. Something to think about in the future definitely.

[@Ricerguy]

could depend on the age of the carbs i had, a brand new remanufactured set was about 1200ish usd, or 80usd per diaphram/slide (mine started to get pinholes) and my emulsion tubes were worn, forgot the price of those. but i got lucky and found the r6 itbs for a steal and the avg price was 60 - 90 usd on ebay, they came with the injectors, harness, tps, map sensor, air temp sensor ( yamaha air temp sensor is the same as my toyota one ) and i'm running a microsquirt v3. do you have an instagram account? :d

[@jarrynsmith]

Thanks for you effort :) Regarding running no map sensor you are going to have a hard time without vacuum advance on your timing map. Like going up a hill at low throttle input and load under idle speed.

[@d4a]

Can you explain this more, especially the "under idle speed" part? Naturally aspirated engines of this size can't go up a hill at low throttle anyway lol the 4age doesn't have any torque at all :)

[@SkalabalaK6]

When you are in traffic and you want to move forward without using the accelerator then by having a vacuum signal mapped correctly it will add timing. And 4AGE has enough torque haha. Map signal works so much better with TPS

itìs a Suzuki samurai, the little 4x4 you see in my image. I could use the 16 version of my engine, which is a dohc design with forged pistons and better rods from factory.

i like how you've mix n matched factory parts to build a better engine, I've done the same with my sr18di Nissan. its easy to just buy this and that kit from eBay and away ya go, but the JDM cars are funny how subtle changes between models when mixed together can make a pretty peppy package. my engine turned out similar in that I was able to increase duration and lift, compression and wind up speed using g all factory parts. my only downside was my factory ecu being odb1 had a few issues calculating things so I had to invent some wiring ( could not find any info on my di version Sr) to get it running right ( Ish ) I really need an aftermarket ecu to properly dial in a tune but from the feelometer I'd say around a 30-40hp increase.

[@d4a]

Feelometer lol :) I like your approach. Where there is a will there is a way! I bet an aftermarket ECU will make that sr18di really shine.

[@brotang2953]

driving 4 answers a basic rundown is after 16 years and 530k she broke a ring or two and was burning more oil than gas. I found a donor n14 gti pulsar, pulled the flat top pistons ( mine were dished ). cams from non roller gti highport on my roller lowport head, shaved head, gti headers ( on the di with its smaller ports the factory gti 4-2-1 headers are as good as extractors, gti flywheel, and removed weird intake baffle / butterfly's in each port.

[@brotang2953]

driving 4 answers issues arised from removing the intake baffle thing. it was vacuum actuated and had a sensor to adjust mixture. with it just hanging it was telling ecu to supply idle mixture. now with it bridged its sends wot mixture all the time. so she's over fueling until wide open but that kinda suits my driving style anyway. I'd like to build my own system but I cannot find any literature in the di. even the Nissan workshop manuals exclude it.

Been watching for a while and this sum-up definitely helped bring it all together. I'm working on a 20v swap in my '85 now and I'm already swamped without trying to document everything and do all the video editing, etc. I'd like to share more but I feel like it takes twice as long when filming. Any workflow tips?

[@d4a]

Oh man I could talk about that for hours. I went through so many different stages of working/filming/editing you would not believe it. It's a really complex process and takes quite some time to improve. One big thing that helped me is to write a small bullet point script for every video. I used to just record and start talking without thinking what I want to say and what is actually relevant. I would then end up with a lot of useless footage that was a nightmare to edit. So maybe like this. Think about what is relevant, don't even film anything else. Visualize the video before you start recording it. Make reminders about what to focus on while filming. As soon as you have footage edit it. Don't let it pile up, it will confuse you later. So this is just where I am at right now, and I will probably figure out something better later on and my future self will yet again laugh at my present self. For some reason I imagined my future self with a monocle giggling in an irritant manner and saying "oh my dear naive boy".

[@notanotherrcchannel]

Hey man! Big thumbs up to you & your channel. Been a proud subscriber to your channel for a while now 😉 Still a question: by now, you probably have the car on the road - how does it drive? Also, does your engine consume/burn any oil after you’ve overhauled it? Cheers from Belgium 🇧🇪

[@d4a]

Hey there, thank you for your continued support. Car is not yet on the road as it's winter here, lots of snow and I won't drive it before spring. So we will know everything in Spring. I do expect quite a bit more carb tuning once I start driving. I don't expect to know whether it burns oil as I change oil far sooner than recommended. I will keep changing it often until I get the carbs completely dialed in as they are running rich for safety now, and the overly rich mixture dilutes the oil sooner than normal. Feel free to ask if you have any other questions.

[@chrisvam]

[@d4a]

As far as I know the 4age 16v twin cam head fits on the 4ac block. It's the same block. But the internals of your block are different to the 4age internals. They are not designed for the same rpms and will not last long at high rpms were the 4age head makes most power. Also the indents for the valves in your pistons won't be right. I think it's a lot easier to get a whole 4age engine and just swap it into your corolla. The 4age engine is still relatively plentiful. You can find it on junkyards, engine importers or breakers I guess.

[@alycestapleton]

Hopefully you don’t get a lean mixture because a lot of people have had issues with carbs on 4age engine and causing it to run lean at higher RPM’s .because you just can’t run the carbs as they are not enough fuel for the 4age engine I’ve seen holes in pistons and damage to ring lands and liner or sleeve

[@d4a]

You're right, the carbs as they are will usually make a funny air fuel mixture. This of course makes sense since they were originally intended to supply fuel to a 600cc motorcycle, which weighs less then a third of my mr2. But that's where jetting and my AEM wideband gauge come in place. I will have constant real time air fuel mixture monitoring to avoid leaning out and will jet the carbs accordingly at different throttle positions.

[@alycestapleton]

driving 4 answers cheers for the reply mate hopefully you’ll sort out any fuel related issues . many people tell me about their 4age engine with carbs conversion it’s something different /fun to drive ,but has a couple of issues most people just leave it with the fuel injection but I’ve seen them both go head to head on the race track and it’s very even maybe only if it’s was a turbo 4age with fuel injection. I’ve got 3 4age engines one being a 20v in my ae82 had originally a small port 16v ,and now I’m planning to put that 16v in a ford laser KE fwd

[@omargill5297]

Only question I have is can I have it? Seriously though nice build

[@rjc862003]

Uh did you do a shim under bucket conversion when you did the cams ?, higher lift duration cams on the 4age require the shim under bucket kit to prevent the edge of the cam from catching` on the valve bucket and destroying the entire engine if you plan on revving this thing to beyond 7k you absolutely gotta have it

[@d4a]

The 4age in its stock form revs to 7.600 rpm without a shim under bucket setup. I didn't do a conversion because I have a mild cam. A shim under bucket conversion is needed only on some seriously aggressive cams. Thanks for watching :)

[@majorpain7248]

Does anyone know how difficult it is to do the head gasket on this engine for a first timer

[@d4a]

If it is your first ever job on a car, like you never even changed the oil before then I would not recommend it. But that's not to say that you can't do it. I would suggest you start with the factory service manual a.k.a. the BGB (big green book) where there are detailed instructions on how to replace the head gasket and everything else. A plus is that this is an old school engine so it's far less complicated than modern marvels of engineering. At a minimum you will need to remove the head and get it to a machine shop to have it straightened again. You will need a few other gaskets replaced as well, mostly for coolant. Replacing the head gasket might also be a good opportunity to upgrade the engine a bit, maybe put it in some sporty cams, since you will be removing them anyway. I would also suggest replacing the water pump and the thermostat, since they are inexpensive items.

[@johns3655]

Daniel Maldonado learn to do maintenance first, then once you know the components of the engine, and can get to the gasket, the only problem will be having the right tools. 4 cyls are easy

[@majorpain7248]

John S ikw how to rip it from head to toe but I just don’t want to fuck up on the timing and torque spec on the head cylinder

I'm lost as to how this is different from a ITB stand point? ITB vs. Bike carb? Looks the same to me well i guess other than the fact itb typically right? Typically uses fuel injection, port injection or w\e and bike carb is a carb lol.

[@d4a]

You said it. ITB is fuel injection and a carb is a carb. Supplies fuel by relying on the venturi effect, whereas the itbs rely on fuel injectors. The word itb is kinds misleading though. It stands for individual throttle bodies and explains nothing about fuel delivery. Bike carbs are also ITBs because they do have an individual throttle body for each cylinder. So it would be more appropriate to say a fuel injected engine with itbs or an engine with bike carbs. But since we all know what is what, just saying itbs is just as good.

[@Limeayy]

Haha, thanks. yea i said it

[@casestyer1166]
