i have a 2003 ford focus.. i want to convert EFI to carbuator?

I have converted a 03 focuse to a circle track car for my Girl... I want to add a carb instead of dealing with this computer stuff. Can not get the car to have any power... so i fig. i would somehow get rid of the computer..

can anyone tell me what i need to do to do this... what i need for parts and how big of a job this is??

will this give us more power?? we took the car up to the track this week and old saturns sl2 and vw gulfs were lapping us?? any suggestions to help maybe keep it the way it is..

our car has a 2.0 spi sohc... with a high performance chip already installed. also has a automatic trans.

thanks norm

please send e-mails to

    If you have a high performance chip already installed, why are you wanting to "convert" it to a carbureted vehicle? You would need to swap to an older powerplant to achieve what you are asking. The only powertrain that comes to mind, would be the 1.6L OHC engine that was used in 1981 to 1983 model years Ford Escort/EXP cars. You would then need the transmission to go along with it, since the 4F27E transmission is controlled by the PCM as well. I believe they were called the ATX. This is unless you want to convert it to a manual transmission of course. After carrying this out, you realize you will NOT be able to legally operate this vehicle on the street, of course. Hope this helps.

    If it wont start...but the starter motor is turning the engine over freely then it is a fuel delivery problem or a ignition problem. But there are several components involved in both the fuel delivery system or the electrical system related to the spark plug ignition. If there is NO spark to the spark plugs you can confirm there is an ignition problem. If there is NO fuel being deliverd to the intake manifold then it will be fuel delivery problem. But pin-pointing the malfuction is the hard part. A starter motor is independant of the fuel delivery and spark ignition system and if it is freely turning the engine over for as long as you turn on the ignition key...but it still does not start after cranking and cranking over the engine...then the problem is NOT from the starter motor. You will have to investigate further

    You can technically take any engine be it efi or throttle body or anything and make it carburated. Its just an engine. The amount of work that goes into it varies but it can be done. Just showing this so that any one who sees this later on knows that the "best answer" is completely wrong. You can take an efi and swap the fuel system over and you dont have to change the engine or transmission.

    you can do this buy a new intake manifold with a capibility of 2 4 barels or 3 two barrels.. take the injectors out and plug the mounting holes.. all the sensors just leave them there.. and disconnect all plugs in the harness.. you need a new ignition device a wire to a switch from the battery to the coil.. and since you are going this far.. a modified exhause.. that is electronic exhause by pass ok. and the fuel line instead of it going to the injector manifold it goes right to the carburator.. ok
