FiTech Ultimate LS EFI 750 HP Fuel Injection Systems
LS motors have a great base for power, but what they really need is something wicked to wake them up. FiTech LS EFI 750 HP fuel injection systems have alarming power, exciting style, and will take you and your vehicle to the edge. FiTech fabricated many aluminum parts for these systems, including the low-profile 102mm billet throttle body, high-volume billet fuel rails, and an intake manifold with a 1,500 to 6,500 rpm powerband and 3mm construction.
Sequential spark and fuel control mate the 55 lbs./hr. injectors, plug-and-play wiring harness, and color touch screen self-learning ECU. This allows you to program two fan control outputs, most tach and speedometer output drivers, and target AFR and timing on-the-fly. A suction cup mounting bracket puts the controller at your fingertips and allows for impressive visual aids.
The optional transmission control feature is suitable for 4L60, 4L65, 4L70, or 4L80 GM transmissions. Awaken the beast and feed its needs with an ultra-performing FiTech LS EFI 750 HP fuel injection system with transmission controller.
Additional features:
* Programmable touch screen hand-held controller with data log features
* 3-bar MAP sensor automatically detects up to 30 psi boost
* AN fittings and fuel crossover
* 24X and 58X crank and cam-compatible and works with custom cams
* Black anodized aluminum parts for style and corrosion resistance
* High-flow, cable-operated throttle body
* Dual Bosch wideband with dual trim controlled
* Knock sensor control
* Stainless oxygen sensor bung
* Compatible with car and truck coils
* Designed for applications making at least 6 inches of vacuum at idle

50015 FiTech Go Fuel In-Tank Pump Modules
FiTech Go Fuel In-Tank Pump Modules
When it comes to converting to EFI, it's important for the fuel pump to be installed in a cool area and what better place than in the gas tank itself. The pump is cooled by the fuel, it's quieter plus there's no chance of fuel starvation. To help ease the installation of an in-tank pump, we offer a new Go Fuel In-Tank Module assembly.
This universal billet assembly can be used on tanks with a depth of 6 to 15 inches. The billet aluminum was designed with the supply and return ports in a parallel position to help route the fuel lines easily and evenly. The vent port is on the other side to ease routing the line near the fill tube. The two fuel ports are threaded to accept -6 AN O-ring boss fittings for a secure, leak-free connection.
The cut-to-fit bracket secures a 340 LPH pump capable of providing fuel to 600 horsepower engines. To ensure clean fuel is pulled into the pump, two size of sock/filters are provided, a standard 11 square-inch design as well as a large, 35 square-inch version. Go Fuel in-tank modules are a direct fit into fuel tanks offered by TANKS Inc.
54001 FiTech Go Fuel Pressure Regulators
FiTech Go Fuel Pressure Regulators
FiTech Go Fuel regulators allow you to set the fuel pressure precisely where your EFI system and engine require. The regulators are able to handle high-flow fuel pumps, can be adjusted from 30 to 70 psi, and can support up to 1,000 hp on gas engines. Crafted from billet aluminum, FiTech regulators feature -6 ORB ports, a vacuum/boost port, and they will accept a pressure gauge. They are offering two models, a compact unit with a single outlet and a larger, dual outlet version.
79100 FiTech Go-Spark Ignition Coils
FiTech Go-Spark Ignition Coils
FiTech Go-Spark ignition coils will help complete your LS EFI swap or even update your modern muscle car with a fresh jolt of energy. These LS coils were developed to deliver optimum output with a quality fit and reliability. They bolt in place of the originals—and accept the sealed, locking connector and plug wire terminal for a simple upgrade. If you're looking for a little more dazzle under your hood, choose a model with a built-in LED that flashes when the coil is firing. All coils are sold individually or in a set.
