Nord engine

A great example of an Alfa Romeo Nord Twin-Spark with ITBs, injection and distributor-less ignition.​

The Nord engine is an aluminum four-cylinder with a double camshaft. 8 valves. Developed in 1954 and in production until 1997. This engine is used in almost all classic models of Alfa Romeo. The best known are the Alfa Romeo Giulietta, the GTV, Alfetta, Spider, 75 Turbo and even in the 155 and 164. The later models of this engine already had the L-jetronic system with a 60-2 triggering on the crankshaft and electric injectors. The older models with carburetor are therefore very easy to convert to injection using the EFIgnition system and some donor parts from the newer engine.

But the newer versions also benefit considerably by applying better electronics, replacing the district air weigher with a MAP sensor and applying distributor-free ignition. We have seen the Alfa Romeo Nord engine in Turbo variant deliver well above 300 hp without further reinforcements on the circuit. Without breaking!

Twin spark

Some "tuners" do not control the 2nd spark plug. It doesn't matter, they argue. The real reason is that their used equipment cannot steer the 2nd coil or lack the knowledge to connect it correctly. The engineers at Alfa Romeo had not just placed a second spark plug in the combustion space. The flame front spreads much faster in the combustion chamber, so that the ignition must be set approximately 10 degrees later in order to get the peak pressure at the right moment. The piston is counteracted less in its rising (compression) stroke. The efficiency of the motor increases as a result. The EFIgnition can control up to 12 ignition coils, so the Twin-Spark engine is no problem at all.

VVT

The later versions had Variable Valve Timing. The system was called "variatore di fase" by Alfa Romeo. This gives the engine a wider power band (high torque over a wider speed range by hydraulically turning the camshaft. An electric valve in an oil channel ensures switching on. The VVT is excellent to control with the EFIgnition.

Necessities

• ECU + Wiring harness
• 60-2 pulley and crankshaft position sensor from Alfa Romeo
• Throttle position sensor
• Coolant temperature sensor
• MAP sensor
• Air temperature sensor
• Broadband lambda sensor
• EV14 injectors for the best results
• 1x DIS coil + cable set for the normal engines, 2x DIS coil + cable sets for the Twin-Spark engines
• Stepper motor
• Boost-control solonoid for the turbo engines
• Installation package

The V6 Busso engine

The 60 degree V6 engine is available in various variants. The simplest is the 2.0 liter with 12 valves. This occurs for example in the classic GTV and 75. The most powerful is the 3.2 liter 24V. In between there are also interesting variants such as the 2.0 24V Turbo of the 916 GTV. It is a beautifully built "even fire" engine. The later models had a 60-2 trigger wheel on the crankshaft as standard. So even the very early models are very easy to convert to injection. We have worked on these engines in the Alfa Romeo GTV (both the classic model and the 916), the SZ, a 155 racer's and many more models, among others. It is a beautiful engine to look at. And they run fantastic on an EFIgnition system.

De Alfa Romeo 155 is er nooit geweest in V6 uitvoering. De EFIgnition systemen maken de motorswap eenvoudiger en de motor draait beter en krachtiger dan op het originele motormanagement systeem.

Necessities

• ECU + Wiring harness
• 60-2 pulley and crankshaft position sensor from Alfa Romeo
• Throttle position sensor
• Coolant temperature sensor
• MAP sensor
• Air temperature sensor
• Broadband lambda sensor
• EV14 injectors for the best results
• 1x 6C DIS ignition coil + cable set or 6 pin ignition coils. If the ignition coils from Alfa Romeo are used, 2x3 channel ignition drivers are required
• Stepper motor
• Boost-control solonoid for the turbo engines
• Installation package

The Boxer engines

Even the 1.4 boxer from the Alfa Romeo Alfasud and 33 is equipped with an EFIgnition. A wonderful engine that makes touring easy. Kicks it easily above 150 hp which is a lot for such a small engine.

Deze Alfa Romeo 33 beschikt over meer dan 150 pk uit een 1.4 motortje.

Necessities

• ECU + Wiring harness
• 60-2 pulley and crankshaft position sensor from Alfa Romeo or a 36-1 universal triggerwheel with universal sensor.
• Throttle position sensor
• Coolant temperature sensor
• MAP sensor
• Air temperature sensor
• Broadband lambda sensor
• EV14 injectors for the best results
• 1x DIS ignition coil + cable set
• Stepper motor
• Installation package

The Twin Spark engines:

The newer Twin Spark engines are found in the Alfa Romeo 155, 145, 146. They are well-balanced engines that can be incredibly powerful when blown. Controlling the Twin Spark system is no problem at all, just like the on-off camshaft adjustment (VVT). We also supported conversion projects where these engines were equipped with a turbo. Among others, Novitec has made kits for these engines. Only its electronics were dramatic. With the EFIgnition this kit really comes into its own. For the later models where the revolution counter and the water temperature run over the CAN bus: No problem. The EFIgnition has a CANbus chip and provides the dashboard with the necessary information.
