Can you convert a carbureted engine to EFI?
A fuel injection conversion replaces a carburetor with a fuel injection system. There are fuel injection conversion kits that make the entire process very easy. Older cars have carburetors, but electronic fuel injection (EFI) offers greater fuel efficiency and improved performance.
Does EFI increase horsepower?
EFI systems are claimed to increase horsepower by more than 30%, while also improving fuel efficiency and controlling systems from timing to nitrous. The HP EFI kit from Holley is a complete and highly tunable engine fuel delivery system that optimizes engine performance.
Which EFI conversion kit is best?

Which is better carb or EFI?
Warren Johnson: Properly tuned, carburetors make more peak power than EFI in a Pro Stock engine. A carb’s pressure differential atomizes the gas a lot better than spraying fuel through an orifice. But EFI has a broader powerband and superior cylinder-to-cylinder fuel distribution.
Does EFI improve MPG?
With EZ-EFI, the exact same mileage loop brought home 18.5 mpg. So there you go-FAST’s EZ-EFI is a bolt-on that works, goes on easily, returns better fuel mileage, and in some cases might squeak out a few more horsepower. When it comes to electronic fuel injection, it just doesn’t get any easier.
