A little different twist ... has anyone went to EFI and regretted it?

If Carburetors are so good why don't new cars come with them. I hate dealing with them, cold starts, altitude changes and getting them just right. I have to say I'm not very good at getting them perfectly adjusted. While Carters are good, I've had problem with new ones out of the box. When I was building that other brand, I use Quick fuel carbs and have a friend dial them in on his dyno, I never did think it was perfect even after that. This coming from a guy who doesn't care about how pure his car is, open the hood to change oil and plugs every 100,000 miles. If it's not broke, fix it anyway!!
 
The new vehicles were built with fuel injection to meet emission standards, not for power or reliability. The latter became true through extensive development.
Sorry Kern, but I have to disagree with you on this.

Yes, fuel injection does help meet emission standards. Less raw, unburned fuel is going through the cylinders, so it is more efficient. This means you can make the same power with less fuel. I don't know about you, but I like that, especially with today's gas prices. And the computer control can adjust EFI better so it consistently does this (as the barometric pressure changes, for example). My father-in-law drag races with a carb on his car. But guess what, he changes his carb every time he races based on weather. Why does he do that? To give it an ideal tune.
So in most cases, especially for street cars, an EFI system will be tuned better than a carb and provide better power and efficiency.

The arguments against EFI could be the same as arguments against using electronic ignition. "Get rid of the electronic mystery shitbox because they will eventually fail and leave you stranded!" Yes, they do fail. But they are much more reliable than points, and provide a hotter spark. Points fail too, and need more constant maintenance. So why would you not want to use electronic ignition?

The point is, both EFI and electronic ignition have proven themselves to be better technology than carbs and points. That doesn't mean carbs and points should never be used. If a person knows them well and wants to continue using them, that's great.

I disagree with saying either carbs or EFI are bad. Like anything, there are pros and cons to each. Learn and understand the pros and cons, and decide what you want for your application.
 
I think for the amount of miles many old cars are driven, it's just not worth the effort and expense. There doesn't seem to be any easy DIY swap to EFI for our old Chrysler junk like there is for a Chevy.

Sorry but none of that makes any sense.

The amount of miles you drive your car is irrelevant to what kind of fuel mixer is on the engine. Most, if not all street driven cars would absolutely benefit from EFI for all the reasons stated in previous posts.

Second, most retrofit throttle body EFI systems are universal. The main differences are the power rating the injectors can support and whether you have a 4150 or 4500 intake. The throttle body does not care what make the engine is, it’s job is to mix fuel and air.

One question here, How old are you? I am guessing you are younger?
WE who did not grow up with a cell phone stuck to our ear or had a lap top in first grade, just don't care to have to deal with all of the BS that comes with computerized cars
I am on a Mustang website ( my current and last project) and I get brain overload reading about dialing in and trying to diagnose their FI cars....
NO thanks.... New jets and lube up the linkage on my carb cars..
The ONLY good thing about FI is what my Machine shop guy told me he believes the FI blocks he see's with NO ridge are because of the lack of the pump of raw gas Carb cars need to start up, creating more cylinder wear...

For me, and many others here, it actually makes perfect sense to leave things as they are.

I will be 52 in May so certainly old enough to have grown up around carbureted cars and remember what they were like.

I got my Coronet in 2018 and until 2020, every single Mopar I’ve owned in the last 25-30 or so years has been carbureted. I’ve spent plenty of time bent over a fender adjusting carbs, timing etc. I’m just not stuck in the past and embrace newer technology if it makes sense.

Again, where does this anti computer mindset come from? Retrofit TB EFI is a friggin’ digital carburetor, what’s the big deal?

Why would you WANT to wash your cylinders down with gas every time you start your car? Why would you WANT to change the tune up whenever the weather changes? Why would you WANT to waste unburned fuel?

I’ll say it again, mechanical carbs are fine and I’m all for them just don’t bash an updated version of them without actual logic and/or reason.

To the O.P. - you couldn’t have thought this wouldn’t turn into a carb. vs. EFI pissing contest, right?

Here’s my direct answer to your original question; if you’re someone that does not mind embracing newer tech. and are willing to out the time and effort into the conversion to make it work despite the advertising and whatever you read on the forums then go for it. If you’re in the other group that thinks you’ll bolt it on and it will be magic then don’t bother.

It's a mind set, next time it snows how many will walk past that old trusty snow shovel to get to that snowblower. To each their own.

Why so proud to proclaim your complacency? EFI is not the end of the world, it’s actually an OK thing.

While this has little to do with our discussion, I’d just like to point out that 87 year old Don Garlits is going 200 in his electric Swamp Rat. Think about that. I have a hard time embracing EVs myself but if he in particular is willing to at least try and make them interesting then I won’t just dismiss it out hand.

It’s the same with EFI. I researched it, asked questions and learned about it beyond the knee-jerk reactions on the forums. Eventually I tried it. Did it work out perfectly at first? No, not even remotely. But the deeper I got into it the better I understood it and the more I liked it.

I bet if everyone put the same effort it to it as I did then there would be less and less carbureted cars anymore.

It’s just a better mousetrap. Have fun whichever way you like but I’ll never stop learning or trying new things.

I'm sure that EFI is an ok thing, but.....

1. If you're driving your classic vehicle a vehicle just a few hundred miles per year, why bother?
2. If you own a high dollar original car, the addition of EFI will drive the value of that car down.

Now, if you have an original slant 6/318 car that you've turned into a Superbird clone and plan on driving it thousands of miles a year, then I agree that EFI is worth considering. But you won't find anyone putting on EFI on a quarter million dollar freshly restored matching numbers 440-6 Superbird.

So 15 years younger than me... HUUUUUGE difference in the digital world.

Stuck in the past?... No, just don't care to have what YOU like shoved down my throat....

Not anti computer, using one right now?? YOUR the one making the big deal out of it.....

Ok fair enough regarding an original restoration. I mean, of course that wiuld be the case but as far as I can tell, that wasn’t what this thread was about.

Again, the amount you drive your car is irrelevant to what air/fuel mixing device you choose. If you have some romanticized notion of having to pump twice and waiting until the choke opens then fine, that’s great. But don’t condemn the alternative without backing up your argument with logical reasoning.
 
Why would you WANT to wash your cylinders down with gas every time you start your car? Why would you WANT to change the tune up whenever the weather changes? Why would you WANT to waste unburned fuel?
Definitely a negative with a carb...Who said I wanted to do this?? A trade off, just like MOST things in life

I guess some of us are just not as bright as you....

What difference does it make how old you are? Frankly, I hate the fact that my kids would rather sit inside on their laptops and surf the web than do anything else. My wife and I have to force them outside sometimes, it sucks.

Stuck in the past?... No, just don't care to have what YOU like shoved down my throat....

No one is shoving anything down anyone’s throat. This is a discussion where opposing views have their own place. I don’t care what you do with your car. The thread was about whether anyone had installed and EFI system and regretted it. I answered how I saw fit.

Not anti computer, using one right now?? YOUR the one making the big deal out of it.....

The only thing I make a big deal about of is illogical or emotional reasoning. Sorry if it comes across some other way but just like you, I have an opinion and chose to state it. Should I not do that?
