Carb-to-EFI Conversion 101

Over the past 3+ decades, EFI became a standard on all modern cars. It increases the vehicle's fuel efficiency, power, and eco-friendliness. Does that mean classic cars will forever remain subpar to modern standards? Absolutely not!

It is possible to do a switch from Carb to EFI on virtually every vintage car type. All it takes is finding a reliable EFI conversion service in Orange County to make your oldtimer into a powerhouse. But, what does this upgrade entail? Is it worth your time and money? That's what we're here to find out.

How to Complete a Carb-to-EFI System Conversion?

In general, we can break down Carb-to-EFI conversion process into several stages:

1. Buying an EFI Conversion Kit. There are a lot of kits available on the market and not all fit every car. Therefore, consult your mechanic to ensure you're making the right choice.

2. Remove the Carburetor. The easiest part of the process. It only takes a few minutes to remove the fuel lines and unscrew the carburetor.

3. Install Injectors. This is where things can get complicated. The intake manifold must be fitted with injectors, which often takes some welding.

4. Fit the Throttle Body. The Throttle Body usually comes with an idle air controller (IAC) already installed. If that's not the case, this part of the job becomes even more convoluted.

5. Install Sensors. This is pretty easy to do, as you only need to screw the sensors into the engine. However, sensors may not be included in the basic kit. So, be sure to check before buying.

6. Reconnect Fuel Lines. Pretty straightforward. Simply connect hoses to the fuel tank and secure them in place.

7. Connect and configure the ECM. Configuring the ECM is what most professionals consider the hardest part of the process. The Electronic Control Module (ECM) is the brain of the EFI. It monitors and controls the entire system. Therefore, fine-tuning it is an absolute must for it to provide optimal results.

Should you attempt to DIY a Carb-to-EFI conversion?

There are many guides out there that make it seem like Carb-to-EFI conversion is a walk in the park. It may be so - for a skilled mechanic. But, for an untrained enthusiast? It can turn really ugly, really fast.

EFI conversion is a major upgrade. It changes how the most essential part of your car works. Think about it this way. If the engine is the heart of the car, EFI is the veins that bring lifeblood into it.

Now, ask yourself this: Would you let anyone but a trained surgeon do open heart surgery on you? Of course, the answer is "no". Therefore, it is best not to practice mechanics skills on the most important part of a vehicle.

Unless you know exactly what you're doing, leave it to the pros. Otherwise, you can expect complications and suboptimal performance. And that is exactly the opposite of what you want from EFI.

Is Carb-to-EFI conversion worth it?

Carb-to-EFI conversion is one of the best ways to bring your classic ride into the modern era. It can make it more economical and reliable, whether you're taking daily trips to Dana Point Harbor, or driving a thousand miles to a car show. At the same time, it will give it some extra "oomph" both speed and power-wise.

There are reports of EFI boosting fuel efficiency by up to 25%. Not too shabby, especially considering the current fuel prices. And, while EFI does not increase horsepower per se, you'll definitely see a jump in performance. All in all, it is definitely an upgrade that provides amazing returns on your investment.
