I think the golden rule is injector colour is NOT always the way of telling
the power capability or flow rate.


For instance.....

On my car, I have did have a set of 750 cc Jap injectors which were the EXACT
colour of the 400 Light blue bosch injector plus they are high impedance !
They looked absolutely identical too.

As a comparison...

Bosch 400's (light blue) rated at 380-400 ish BHP.
Mine are around 470-500 BHP


(I ended up spraying them an unusual colour as people assumed only 400 bhp - PINK )


Having said all that, just fitted a set of Rochester 1000cc's now
