Running D16a6 manifold and injectors on D16Z6
Goin with a t25 @ 6-7psi
Some say I HAVE to have 450's others say stock will do.
Anyone clarify this for me?
I'd like to use the stock injectors for now if its possible

 

Your fine running 6-7 psi on the stock injectors. If you decide to boost anymore I would get larger injectors though. This question and answer is in the FAQ you know...

 

beerbong, you have the ugliest avator makes me wanna slap you for still having it. get a mask for that pretty face.

 

Farva's Number One!!! Farva's Number One!!!

 

I think this will depend on what you are using for fuel management.

THREAD JAK Dr.Boost yer sig is finally making me feel bad for that kid....

 

^^^^^ that is the answer, VAFC you NEED 450cc otherwise you will max out your injectors duty cycle.

FMU you dont need to replace injectors but a fuel pump is a good idea.

 

Uh, you don't need 450cc injectors to use a V-AFC. The size of your injector depends on fuel management alone. If you're scaling MAP signal, you need a larger injector, yes, but not 450cc, definative. As I corrected you in a previous post, 370cc, even 340cc injectors will work for "high boost" applications, depending on what you consider high boost. 340cc will support 8psi.

Also what comes into play is cubic feet per minute that your turbo is producing.

Fuel management is not definative...

 

like what maybe gsr injectors?
those are 3 something. Im not certain though
