Injectors

[mattspyder]

What size injectors would be good for a 18g turbo with about 20psi boost.
i was told I atleast need 780cc

I run 11's with 660's
boosting 20psi on a garrett v-trim
Tuning with a afc neo
I see your using the safcII so i wouldnt go larger than 660's
They might not play nice with eachother.
If you plan on going with the link or stand alone might as well get 1000cc there not that much more and you will more than likely want them later anyways.

I Agree With Pitbull 660's Should Be Enough For 20psi On A 18g

 

[mattspyder]

reason I ask is the mechanic rebuilding my said I have to go with atleast 780s or i will run to lean and burn the cylinder.
I want to know the gods honest truth.
I currently have 650s (which the shop doing the rebuild says are 680cc. something about the numbers being the same?)

he tells me one thing then I hear another thing on here, well which one is it?
I have a safc II thats why Im worried about tuning??????


down the road I would like to get dsm link but thats not a for sure yet?

what do I do

 

[vaboys2ndgen]

do u have a logger along with the safc?

only experience i do have is i ran 450s on a 14b at 20psi.

People are running 650's on a 16g at over 25psi. You will be fine with those. Your mechanic is not that smart if he thinks otherwise. Or he wants more money from you.

 

[mattspyder]

yes I have a logger, if you dont know for sure if 650s will work 100% fine with a 18g then dont answer. I dont need more I think so... answer....

 

[vaboys2ndgen]

no need to be a dick, at least its an answer. btw 650s/660s are more than enough for only 20psi!

 

[JohnCIV_Talon]

Maybe if you would listen to what people are already telling you, you would have your answer. If your not gonna listen then dont ask. 3 people have agreed it will work. aN 18G IS barely bigger then a 16g, and people have tons of room to spare on those running 650's at 20psi.

650's will be fine for an 18g. If you go any bigger your going to struggle tuning them with the S-AFC.
