This technical info shows the combination of EVO and GIRS12 injectors and the ratio of use between engine capacity / engine power, with the aim of helping to identify the size of GIRS12 injectors suitable to replace EVO injectors.

The name of the distributed calibrations indicate the type and size of the injectors used in the prototype calibration. The size of the EVO injectors is shown in different points on the rail, based on the body, whether in plastic, or metal, or by the colour of the nozzles. The size of the GIRS12 injectors can be recognised by the coloured caps of each injector.

L White > 77 > 85 > 114 > 143 >190 > 229

The second table suggests the use of the correct injector size, based on the engine power and the number of engine cylinders. However, at the end of the installation it is better check the vehicle on the road.
