dose anyone know if you can pass emissions if you do a switch to carb my car was originally a 4 cylinder car and this is my first time building a mustang so i don't know much about them
Does AZ do a visual inspection? You didn't mention the year of your car, but I'll assume it's 87-93. If so, you'd likely fail a visual, even if you could get it to pass the sniffer.
It will not pass, and you may be subject to fines and jail time. Removing the emissions from a car that was equipped with emissions equipment, no matter what the engine was is a Federal crime.
If the car is for race track only you can do whatever you want to it, with the exception of driving it on public roads. Make it a race track only car and you can put whatever carb and engine combination you want in it.
Some states will not title a car unless it will pass emissions inspection.
Most EFI to carb guys seem to be lacking some understanding of how EFI and electrical circuits work. Here's some help...
Here's a book that will get you started with how the Ford electronic engine control or "computer" works.
Ford Fuel Injection & Electronic Engine Control 1988-1993 by Charles Probst :ISBN 0-8376-0301-3.
It's about $25-$35 from Borders.com see http://www.amazon.com/ . Select boo...autoshop16.html]Automotive Online Instruction for a beginning course. The course is very good and best of all, it is FREE!!!
it is against federal law, and I highly advise against it.
However, if you're in a state that doesn't test emissions, then you should be fine.
I have a 66 mustang, and "technically" by law I'm not allowed to remove emissions components. However it is not subject to smog checks any longer, and no way in HELL am I ever going to put a smog pump back onto it.
However, going efi TO carb is drastic. Take the time to Learn efi. EFI is SO nice. I finally got my 66 running for the first time under dinasaur technology (aka carb'd) and it sucks. ALthough it's cheaper....It's going to take me a million years to tweak and tune that carb to where it even feels close to EFI.
I'm spitting distance away from pulling the trigger to go TO efi on my 66.
