These MSD Atomic EFI fuel injection systems are the perfect choice for anyone planning on converting from carburetor to fuel injection. They include a throttle body, power module (with wideband oxygen sensor), and handheld controller. The throttle body features an integral ECU built on the side, incorporating the TPS, MAP, IAT, and fuel pressure sensors, all in one location. Fuel delivery is provided by four precision 80 psi injectors featuring a stainless steel ball and seat metering method for maximum internal sealing. They also use internal fuel rails, providing a sleek appearance and removing fitting connections where leaks can develop. Atop the Atomic EFIs are annular booster rings that deliver superior atomization of the best fuel mixture, ensuring the best possible fuel delivery. Best of all, the MSD Atomic EFI fuel injection systems bolt directly to any standard square bore carbureted intake manifold and accept the same linkage as most carburetors. The 1.75 in. diameter throttle inlets ride in precision roller bearings for a smooth pedal transition. The Atomic EFIs' unique TPS is a self-calibrating, non-contact sensor, which means that you don't have to worry about configuring it during setup. The included power module is a remote mounted piece that handles all of the high-current loads. MSD's CAN-Bus technology allows for a single, clean connection between these units and the throttle body mounted ECU. Control all of the MSD Atomic EFI fuel injection systems' functions with the hand-held device. Initial setup takes about five minutes, and you'll answer six questions about your specific engine. After the initial setup is complete, the device can provide you with engine data to help you keep your engine working properly. They also feature a removable micro-SD card to record and store data so that you can see what's going on with your engine.

Multi-port EFI systems require a stable fuel supply to maintain the best performance throughout the engine's rpm range. MSD high-pressure, high-flow fuel pumps feature a roller vane pump mechanism, which is extremely resistant to clogging and jamming. The pumps mount in-line (out of the tank) with two supplied cushioned clamps for a quick and sturdy installation. The wire terminals feature brass studs for secure connections. These MSD pumps are ideal as "boosters" for nitrous oxide applications, or as stand-alone pumps for multi-port EFI systems on engines up to approximately 500 hp.

The GM LS Series engines are being built for a lot of different performance and racing applications. You can see good ol' hot rodder ingenuity taking place as racers are running carburetors and even using distributors on these engines! These MSD LSx trigger converters plug into the factory crank sensor of an LS engine. They then convert the factory trigger signal into a 12 V square wave signal to trigger an MSD ignition control such as a 6 or 7 Series ignition control. If you are incorporating a front mount distributor into your LS engine, this means that you won't need to run an external crank trigger.
