i come from the mustang world where the injectors are colour coded...ie..orange 19lbs, blue 24lbs and green 42 lbs...are they colour coded on the mini as well???
mine are white topped, would that be stock or who knows??
cheers

 

Sorry no, the injectors are each the same colour, along with being able to be placed with whatever cylinder you want. I've replaced mine and each injector was exactly the same as the others. No difference.

 

JCW is blue/black.....
Not sure what you have....does not sound like OEM.

 

The stock R53 injectors are a kinda sand/tan color and black. But some of the rebuilt injectors will be the same color. If I was betting you more than likely just have stock injectors, unless the car came with a ton of other mods.

And yes the JCW 380 cc injectors are blue and black, here is a pic
