What is the biggest size injectors that the stock NA fuel rail can hold?

I'm trying to see if I'd need to upgrade the fuel rail if I put in 660cc injectors in my car.
Thanks

i dont belive you need to upgrade...... if i remeber correctly, boostlogic offered injectors that fit right into the NA rail and went all the way up to like 780cc or something like that...... they dont seem to offer them anymore, im running 525cc injectors in mine from boostlogic
1600cc injectors will physically fit just fine. But the id of the rail probably isn't enough to support them.
yup its like getting a huge turbo and having 1in downpipe and exhaust
So you all think that the stock rail can support 700'scc injectors?
I want to get 700's cc injectors now. If the stock rail supports them I'll keep it and not have to spend the extra money.

I have 780cc injectors in my stock rail/fuel system. You should have no issues. Injectors were purchased from PTE.

RC 1000cc injectors modded stock rail. Over 760 whp.....
precision

Sorry for the stupid question.. but what is PTE?

same question.. low or high?

whats PTE website?

thanks
Anything larger than 650cc from PTE is low impedance.
RC makes a 750cc high impedence injector. I think that is the largest high imp drop in injector for the GE rail on the market.
I got 680cc from PTE (lo imp) willing to trade....=)
