won't to change my standard blue injectors on my 4x4 saph for a set of dark greens i have them already would just like to know how to fit them? lol

 

undo the fuel rail and pull them out

 

u changing the chip and map sensor and checking fuel pressure also?

regarding ur Q undo the fuel rail from inlet manifoldand undo the fuel pipe at the regulator,fuel rail will pull of with the injectors and once off there are clips at the top of the injector that holds them to the rail!

 

yea i know forgot to say lol been long day stripping me engine

 

yeah changing map sensor and chip too, is fuel going to pis* out everywhere? lol do i have to disconnect the earths?

 

you will loose a little bit of fuel nothing too terrible thou! NO

 

dissconnect battery first and im sure ur be fine

 

thats ok as long as it aint pooring out everywhere in my garage! thanks for your help i'll let you know how it goes!

 

forget get me if im wrong but i understand that dark greens only produce power up to 330bhp and the 4x4 blue injectors do up to 400bhp and greys 0ver 400bhp or am i wrong

 

dark blues are same as yellows but light blues are over350 i think but greys are over 400

 

so what are 4x4 injectors light or dark blue

 

4x4's come with dark blues as standard

whereas 2wd's come with yellows as standard

i dont know about light blues but think there for 400 to 420 bhp

they come before greys
