I swapped an '86 F150 from EFI to a carb. Holy shit what a mess, it ran better in nice weather but as soon as shit got extreme, it turned into a pain in the ass. Anyways here's a small list of things you (probably) will have to do

manual fuel pickup
mechanical eccentric with mechanical fuel pump (will probably require a new timing cover with fuel pump provisions)
new distributor gear
in line fuel pressure regulator
new cables for everything

be prepared for the thing to run like dire ass when its done, enjoy your 3 hours of fine tuning and finding microscopic air leaks around the carb

usually there is a kit. there is for my car if i wanted to.

but its expensive, and an engine swap is cheaper

>>15463591
I mean thats what cars are about
if you have a problem get out
EFI is 10x worse

>>15463603
i want to swap in a silver top or black top 4age , carb it, and turbo it.

>>15463591
why would you bother with a mechanical pump at all? its more work

>>15463608
I don't think you understand how much more work keeping a carburetor tuned efficiently is
>>15463624
mechanical fuel pump was one less thing to go wrong since the electric systems in old fords are nightmares, and i didnt feel like splicing in a pressure regulator since the fuel pressure with an electric pump was like 50-60PSI at the engine

plus with a mechanical fuel pump, fuel flow is dependent on RPM so you're never really starved unless you're trying to make retarded high numbers.

>>15463648
um you know you can just use a electric pump meant for an carbed car right?

>>15463227
>EFI to CARB swap how?
By putting a gun to your head and pulling the trigger so you don't pollute the world with your idiocy.

>>15463658
no need for the unwarranted condescending tone. I think I made myself perfectly clear why I used a mechanical pump in the post above

you have to drop the fuel tank to swap the pickup out, made more sense just to pull the electric fuel pump and slap a mechanical pump on the front. saves you more headache down the road when the el cheapo 9 psi electric pump takes a shit

>>15463227
Swapping to carbs? What kind of retarded boomer shit is this?

eh not all old cars had good efi

some had throttle body injection. not better than a carb

it would depend on the carb you chose, and where you put it, before of after the turbo

if you put the carb after the turbo it will be much harder to tune.

dude i saw a GTS Corolla over in pick n pull the other day, was a shame to see it go like that, motor was still in there.
I also hear that people are using motorcycle carbs for d series n stuff? something like a CR carb? My Honda bike runs those currently. If you go that route;

This book is highly recommended from others that work on older motors that have forced induction and carbs. https://www.amazon.com/Turbochargers-HP49-Books-Spark-Ignition-Applications/dp/0895861356

its pretty cheap too, consider it as reference material if you want to actually go through the project.

Serious question.

What are the benefits to carb conversion? Why do you pl do it?

For a racing engine project, is carb better?

>>15467438
i can't imagine that there is a performance edge that a carb would give you, its probably like 10-20hp on the peak power? Except that the price point is much cheaper(thousands vs hundreds), and really it does not require electronics.

I think pro-stock cars are currently only running carb setups. Everything else has moved over to EFI. Carbs certainly are cool tho, the airflow sound it makes is nice.

you can get the same thing from an ITB swap.
ITB has all the benefits of the carb, none of the drawbacks.

pic related, carbs

>>15467690
ITB = individual throttle bodies?

What is the difference?

um one throttle body per cylinder
most cars have just one

I better read up on it.
Any good books to recommend about throttle bodies / carbs? Racing fuel delivery?

and carbs again.
i do not want to get into the specifics of it, but the benefit of individual runners with no plenum is better running when you have a big cam. it sort of tames the cam a it. side affect is improved response and cool noises.

It really depends on budget and what you're looking for.

Carbs are usually cheaper/easier to build, but EFI offers many advantages in tuning and power efficiency.

carbs have style too.
efi is usually ugly

>>15467715
Im thinking about an inline 4 with ITB.

can you get them custom built?
Im looking into older carbed engines, is it relatively simple to make the ITB conversion?

>>15467729
99% of the time you just order the weber intake manifold, and buy the throttle bodies separately.
then you run a megasquirt or whatever

Find an older manifold or make your own; pic related is a fabricated manifold:

Same engine with a sourced carb intake; adapted to use a Ford carburetor instead of a dual Solex setup (Intake is from a Peugeot 604)

>>15467764
>>15467808
interesting.

Do carbs have any benefits over ITB's?

>>15467830
No, but it had the same mechanical fuel injection system; Bosh k-Jetronic garbage. Certain parts are nearly impossible to find these days; those that are available are crazy expensive, so I had two choices: EFI or carb. I chose carb because it was easier than trying to create and tune an EFI setup.

>>15467856
Mostly it's just the lack of sensors. If you're running ITBs, you still have to adapt the sensors it requires for proper tuning and, while it's about half as many as ITBs, it doesn't offer close to the degree of adjustability that ITBs have. ITBs are an awkward hybrid of carb and EFI that lacks the benefits of either setup.

While carbs may be fading remnants of boomer tech, they're remarkably easy to learn. I don't claim to be an expert, but I was able to adapt my own Peugeot intake setup with no outside help and I'm 27.

>>15467891

Im 26, finished Uni few months ago. I honestly cant wait to start working and investing into my passion for cars.

I have a lot to learn but once I start at least I'll be doing something.

Carbs might be a good start for me, I plan to buy an old carbed car anyways. I just want to make it better with some racing intake/carb/fuel delivery, among other things.

It would serve as my ''learning curve'' vehicle.

honestly i posted pics of webers because they are truly the most simple of carbs you will find on a car.

they are still being made in several factories for some strange reason too.

>>15467983
Yes, but parts are not readily available for it in the US. I like to actually drive my cars, so I prefer my cars to be as simple as possible.

Thanks for this link, I will look into it, especially the carb in question.

Why do you want to down grade? EFI is superior to carbarated.

Carbs are less ideal for turbo. Get mfi for tunability at wot only. Enjoy your toy car.

Carbs are literally steampunk for gearheads
All steampunk faggots like obosolete, underperforming, unmaintable shit

>>15472575
>being this much of a numale

>>15472575
First of all, "obosolete" isn't a word.

Carbs are still used in many industrial applications where electronics are a hindrance. Anything that will sit for prolonged periods is better off with a carb; that's why nearly all small engines have them.

Under-performing is debatable; here's a great article about setting up a 5.3 motor with both carb and EFI:

http://www.superchevy.com/how-to/engines-drivetrain/sucp-1104-ls1-carburetor-vs-computer-performance-test/

tl;dr the EFI setup is significantly more expensive, more difficult to tune, and saw a net gain of 20 horsepower. If you spend the same amount on a carb setup as an EFI, you can buy more and negate the difference; if not come out ahead.

Carbs are also extremely easy to maintain once you get used to them and can be rebuilt for next to no cost.
