who 's running a carb set up insted of fuel injection?

[godstangit]

Im getting real tired of playing with the FPR, to adjust fuel, tired of scanning for codes,and making all these adjustments only to have the PCM re-adjust everything back, and Im not looking forward to buying a Tweezer, or a chip and dyno tune for 500.00,Im thinking old school,carb,and screw all sensors,and computer that drive us crazy when we mod our cars. Considering all the work I've done (see sig) the car has it's good running days, and other days (when it's hot as satans ass here in Florida) it runs like *****, Iam loosing it man! Who has ditched the fuel injection for a carb setup?

I have given switching to a carb ALOT of thought with my new engine.. It may "seem" cheaper, but to set up the carb up right, it will be pretty expensive, especially if you already have all the FI parts and are selling them and losing money.

I would search under fuelie vs carb, here and at the corral, you will have a wealth of knowledge on the subject after reading everything.

Just a few thoughts: You will need a new fuel pump of course, you will need to sump the fuel tank, and will need a new larger fuel line (since carbs flow high volume and low pressure). I believe the carb pumps run dead headed, so no return is needed. The stainless steel braided line and fittings are expensive..

Theres alot of little odds and ends needed to get the carb setup right. I would just stick witht he fuelie, and get the car tuned correctly by someone, or buy the tweecer. From the sounds of it, you dont like messing with stuff, so just get a tune and call it a day.

I say keep the fuel injection and invest in a tweecer (it'll cost just as much as switching over to carbed if not cheaper)

Just so you know... my dad has been working on his carbed dune buggy for the past month, swaping out jets and what not to get it to run right... Still not perfect. I think you'll be a lot happier keeping the EFI and getting it running right than converting over to a carbed setup.

the automotive industry abandoned carbs for a reason....

I say go with the carb, I agree with you man about all the trouble of FI, thats exactly why I went with a carb when I did my swap, dont want a computer controlling my car, and when something goes bad with FI, you have to go through a lot of trouble shooting, and with a carb, it can only be like three things wrong, and you can still use your stock fuel pump, just get a fuel pressure regulator, and it has a return line. If you do go carbed, you need to get a torker II intake, so it will clear your hood.

Tell that to the carbed guys making 1000+HP.

what about the Supra's making 1000+hp with a 6cylinder??
no way your touching that with a carbed 6....

That is comparing apples and oranges man, don't do it. Anyway to get back on topic, I would stick with fuel injection. With all the time and money spent on retro-fitting to a carb you could have a rock solid FI system.

I have talked to many people who have tried to use the 3 port regulator,and most say it does not work. it especially will not work if your making big power. Like i said the "correct" way to settup a carb, is to get a CARB fuel pump(holley blue), sump the gas tank, and run new lines. THink about how small the fuel lines are on FI cars, versus what a carbed settup needs. The lines need to be MUCH bigger, like i said, high volume, low pressure.

Thanks for all the opinions, YELLOW 95- You're right, the fuel pump and lines along with throttle linkage,vacuum lines,and more would have to be re-fitted,but question.... why would the gas tank have to be sumped? Also I do enjoy very much working on the car, in fact everything I've done to the car,I did myself,except the gears,it's just frustrating to make adjustments,or mods and them not making the motor respond,to the full potential cause of the PMS.It seems that we are having to actually pay twice for our cars to perform like we want them to, first we buy the HCI,MAF,etc,then we have to spend an additional (insert amount here) to get it to run right. Like I said it's just frustrating FI systems are great,and I know they are superior as far as efficiency, but I don't think you can beat a carb set up, as far as bolting on your go fast parts, making a few tweaks (a few) and enjoying your ride right away.

We have OBD-II cars which means you can't just slap a carb on and go. All the guys who have gone carb on this board have disappeared.

As far as i know the carb pump needs to draw fuel from the bottom of the tank. It will not be able to suck it up and out. There are some good sites on setting up a carb fuel system(ill try to find them), it ends up being more costly/time consuming then you might think.. I weighed the odd's many times, but decided to stick with the FI and hope for the best..

First off I did a FI to carb swap on my camaro and I was very happy.

You do not need to swap in a new pump, or sump the tank. You can run your factory fuel pump you will just need a good fuel pressure regulator like a Mallory 3903 3 port return style reg. They work great. I like having the freedom I do with my carb...no need to worry as much about what cam I run, its very very easy to tune. I could do a head/cam swap and have it turned pretty well in 15 minutes or less easily.

But fuel injection definetly has its pluses. You will get better milage (granted its actually tuned right), it will be faster, but like mentioned above its expensive.

Also on the fuel pump...I decided to replace my factory intank pump with a holley blue 110gph pump. I left my return line hooked up with my fuel pressure reg so it will always cycle gas...keeps the pump running quieter and keeps it from boiling from heat.

If it comes down to it I am gonna rip the FI off my 95 GT and swap to carb...I still can't get it running right after the engine swap.

I hope I covered everything....if you have more questions drop me a IM on AIM at :::gasp:::: camarosportcoupe

Hey I may be a chevy guy but this swap is pretty much exactly the same for both chevy and fords...and yea I drive a ford...when it runs
