If you have a vintage intake designed for Weber carbs, Borla Inductions can provide throttle bodies to match.
Borla Induction builds retro-style Weber intake manifolds and EFI throttle bodies for V8 engines that resemble a Hilborn mechanical fuel injection system . Now the company is offering the parts to convert most any Weber-based intake to EFI.
“If you have an intake manifold designed for Weber carbs, chances are it can be retrofitted it with throttle bodies and EFI,” says Borla’s Ed Taylor. “Currently we are working on several tri-power systems for future release.”
Many intakes from Borla feature vacuum plenum integrated into the base. Note the bleed holes in the intake ports that feed correct information to the MAP sensor and help idle-air control functions.
Borla Induction has also acquired Eight Stack, a company which manufactures EFI throttle bodies that very closely resemble Weber downdraft carburetors. As with its other retro-style EFI intake systems, there’s more to the design than just physical appearance. Many of the intakes have a built in vacuum plenum that connects to all eight cylinders, which helps with idle air control and provides a proper signal to the MAP sensor. So even if a single throttle blade was slightly out of alignment, it would not upset the fuel delivery program.
Small-block Ford systems are the most popular.
“You can even run an aftermarket ECU that’s designed for self-tuning,” adds Taylor, noting that some systems can be configured for a returnless fuel system. Properly set up, these systems start and run as good as any daily driver.
The most popular applications cover the 302 and 351 Windsor’s, as enthusiasts strive to duplicate the classic look of the Weber-equipped small-block Fords that powered the racing Cobras in the ’60s. Borla Induction even has a unique cross-ram version with 50mm throttles. Other applications for Borla Induction products include both FE and 460 big-block Fords, big-block Chevy, small-block Chevy, LS1/LS2 Chevy, LS3/L92 Chevy, and the 6.1-liter Dodge Hemi. The newest application provides retro EFI intakes for the 5.0-liter Coyote.
Numerous appearance options are available for the systems, such as different powder-coated colors, polishing, and different air-horn lengths.
Intake systems are available for LS and Coyote applications.
