Can someone please help me with something. DSM people that is. what do the different colors on top of the injectors mean(what is the rating for their color) my buddy has some "silver" tops, and he is claiming them to be 450cc. but i thought the blue ones were 450cc. he thought that the blue tops were 550cc. anyhelp DSM fans? thanks

 

Grey tops are 390's Part number will be b390l or close.

 

anyone else hear of silver tops? thanks

 

i have another question. when i put 450cc injectors into my car when i turbocharge it, do i need one of those resistor packs? or will my VAFC contrller have it?

 

what exactly is it, can i make it myself? i am in electronics classes in my school right now. he wouldnt care if i made it. what kind of circuit is it, how much resistance is needed? thanks

 

go to radio shack and buy 4 10ohm 10watt resistors and run them inline with the injesctors... its like 5 bucks.

 

i can get the resistors for like 10cents a piece

 

what do the resistors do? i know wat A resistor does, but why do i need to reduce current flow?
