Japan Electrical Control Systems formed 1973 as a joint venture of Nissan and Bosch.

1 Feed Type
2 Colors
3 Part Numbers
4 CA-Series
5 SR-Series
6 RB-series
7 Dropping Resistor

Feed Type

SR: side-feed injectors (most)
SR: top-feed injectors (some)
RB25: side-feed injectors
CA: top-feed injectors, low impedance (requires dropping resistor)
RB20: top-feed injectors, low impedance

Top-feed means the petrol comes into the top of the injectors, and is sprayed out the bottom. In a side-feed design, fuel enter the side of the injectors and is still sprayed out the bottom. Top-feed allows a simple fuel rail which snaps over the injectors, while side-feed requires a more complex gallery-type fuel rail.

There is no real advantage to side-feed or top-feed, except in manufacturing methods and packaging considerations. Performance-wise, it is more important how much fuel a particular injector flows. To switch from one type to another means changing the entire fuel rail.

Colors

Wheel HP listed is appropiate power level of the injector set for a conservative tune (not saturating the injectors).
