SBC EFI-IR Kits
We engineer the components for our EFI-IR kits for each specific application, sourcing product from the finest manufacturers so you don’t have to worry about compatibility issues. Our kits include a HILBORN EFI-IR manifold, engine management suite and fuel system, along with a remote thermostat housing and synchrometer.
HILBORN EFI-IR Manifolds
HILBORN EFI-IR manifolds are not conversions, but are engineered at the foundry level to accept the EFI components. Our racing experience has taught us that one size doesn’t fit all, so we design each manifold around your specific application by picking the correct butterfly, fuel rail and injector nozzle size. Multiple butterfly sizes give us the flexibility to tailor the manifold to meet your horsepower requirements or drivability needs. All manifolds are finished in a protective clear anodize giving them the distinctive nostalgia grey color. Many other finishes are also available so be sure to check out our finish options page. As a True IR design, it does not have a plenum that is all the rage today. To read more about plenums and IR manifolds, visit our conversation titled “what is a true individual runner manifold?” on our FAQ page. Ram tubes made for your designated height top off the injection system you have always wanted.

The heart of any EFI system is the engine management system. Today, the most requested feature is self-learning. Although this feature will help eliminate some of the manual tuning that was a requirement with older systems, it is not a perfect technology, so we only supply ECU’s that have lap-top access in order to fix troublesome spots that the self-learn alone cannot fix. We have learned that high horse power and race only applications will require more hands on tuning to extract their maximum potential.
As part of the kit we provide an IR specific base calibration, along with comprehensive technical support to answer any questions you might have. As this technology advances, we will continue to offer the latest in aftermarket features, integrating them into your system.

The HILBORN Advantage
HILBORN Injector manifolds are a true individual runner (IR) manifold, providing the best all-around power output and drivability of any other induction system. To learn more about true IR manifolds, click here for our FAQ page.
A true IR does not suffer from the disruptive cylinder to cylinder reversion pulses associated with a common plenum intake or IR manifolds with a plenum chamber. These pulses promote fuel separation from the air carrier, the slowing of air movement in the manifold, and the inability to realize engine potential due to poor cylinder fill and burn characteristics in the combustion chamber. However, the IR design of the HILBORN manifold isolates these pulses, allowing the engine to make more bottom end torque, have increased throttle response and, most importantly, to accelerate faster. Most applications will also see a significant increase in top end power. Elimination of these reversion pulses is also responsible for our excellent low speed drivability, even with aggressive camshafts.
Enhanced engine performance and drivability all in one package? Yes, with a Hilborn EFI system on your car, you can experience a total transformation of your engine. It is possible to have the best of both worlds with a HILBORN. Contact us to find out more.

: Our fuel injectors are manufactured strictly for use with high performance engines for racing and off-highway use only, and are therefore subject to the unusual stresses normally associated with this type of use. Since the operation of these engines is far in excess of the safe limits that are usually set for engines, breakage and failures are common, and are an accepted risk in racing. Also, the history of racing has always been one of trial and error by the users of this type of equipment. Therefore, because of the many unknown factors involved in experimentation, and because of the safe limits being exceeded by virtually every part in the engine, we do not offer a warranty of any kind on our equipment. It is purchased and used by the buyer at his own risk and with this understanding. If any of our parts become defective after purchase, the buyer assumes all cost of service or repair.
: Fuel Injection Engineering (FIE) is providing all information herein to familiarize potential customers with its’ products and services. Because racing is inherently dangerous, no representation of your safety is implied. To the extent permitted by law, this warranty is exclusive and in lieu of all other warranties or representations, whether expressed or implied, including any implied warranty of merchantability or fitness for a particular purpose.

All HILBORN manifolds come standard with a clear anodize coating which provides the timeless nostalgia grey finish.
But customizing your HILBORN Injection to make it everything you’ve dreamed of is easy with our custom finish options. See below for a description of these options. Be sure to visit our finish options page to view colors and examples.
Polishing/Ceramic Clear Coating
Few finishes beat the glow of a highly polished manifold, making this is our number one finish option. Polishing can be mixed and matched with other finishes to provide a one of a kind manifold not soon forgotten.
Love the polished look, but not the constant upkeep required? Pair your polished manifold with our clear ceramic coating that eliminates the ongoing maintenance. Our clear ceramic is a high temperature, non- yellowing, scratch and impact resistant coating that eliminates the constant upkeep needed with bare aluminum. Once the manifold is polished, it receives a high temperature steam bath to remove any polishing residue before the ceramic finish is applied. Our ceramic clear will keep your manifold looking like new for years to come.
Our ceramic coating is a high temperature, scratch and impact resistant coating, typically used on headers, that will protect your manifold from the bumps and bruises experienced by any application that is driven, raced or worked on frequently. Available in select colors and as a matte finish only, they are perfect for those looking for the best overall protection or to fit the more high tech looking engine bay that is trending today.
For the most comprehensive color and texture options, powder coating is the best choice. With literally hundreds of colors available we’re sure you will find the perfect color for your special ride. Check out our powder coat color chart to see the numbers offerings!
Chromed ram tubes are the crowning touch to your HILBORN fuel injector and is the perfect maintenance free option that fits with any manifold finish.
Unfortunately we are unable to chrome the manifold itself.
