Ok,

No one in the single turbo section seems to know the answer, so I'll throw this at you guys.

I'm looking at buying a set of 1600cc injectors from five o motorsports. The have two different ones. My question in what is the difference between the bosch green/blue top 1600cc and the cream top 1600cc injectors. Will I have to modify my secondary fuel rail regardless of which ones I use? I'll be controlling them with a Halteck E6K if that makes any difference.

Thanks for the help.

 

I got the green tops because they did not list the white tops. I cannot tell you what the difference is.

Both of them will require modification of the rail or injectors.

I modified my injectors like this: http://home.mn.rr.com/linnihan/1600c..._injectors.htm

 

Are the green tops the low impedance injectors? Did you have to add a resistor? I hear that you need to add a resistor to the injector when using a low impedance injector. Not exactly sure what the reasoning is behind that though.

 

With aftermarket EMS, no resistors are needed.

 

Thanks for the help guys. Now I have a new question. I'm looking at getting a pair of Greddy 720cc injectors for my primaries, but the price is a little steep ($140 per injector). Does anyone have a line on some 720cc made by someone else and a link to their site?

Thanks again for the help.
