I'm looking to make 400 on pump and 500 on C16. I was wondering what injectors most of you guys have had luck with? Which ones are the most streetable and reliable? And off course what size. I am gonna stick with the stock ECU for now..
thx

I saw these on Ebay.. are they any good?

I currently use pte 780ccinjectors with stock maf. I made 452whp with these i would think these are good for about 500 but thats it.

 

780s should be more than enough, remember on c16 or alky your duty cycles tend to go down...

 

880cc.

 

If your running the same boost...... If your running more boost with race gas you will still need a lot more fuel than on pump regardless of the octane.

not true with c16 or any high octane gas your duty cycle goes down and you use less fuel.

 

noooo
you duity cycle only foes down if you use meth or alcohol injection.

with high boost and c16 you use a lot of gas.
with stock fuel pressure you really need 1000cc injectors to stay under 80% duity cycle.

i had 780cc injectors when i was making 500whp in my fwd integra and they were maxed out so i upgraded to rc 1000.

if your running any kind of ems theres no reason to even buy unjectors smaller than 1000cc wether your making 600whp or 300whp. aem can idel them like stock and it will give you room to grow.

 

Wow.

Since you staying with the stock ecu, 780 should be good.

 

800cc sards

 

With C16 and an AFR of ~12:1, 750cc will be fine. If you're concerned, 850cc is definitely more than enough.

 

Thanks for All the Help.. I'm going with the 780's for now since I have the stock ECU and I have a meth kit just incase it is not enough .

Does there seem to be any preference with Brand of injectors?

 

For a 780cc PTE would most likely be the most popular choice and priced right as well. Or you could look at FIC injectors (fuel injector clinic) they have a 750cc like Ted B stated that should work for you as well.

 

Lots of them are the same generic injectors rebadged, there is a difference however in the performance depending on the style of injector, I'll let Ted B come back and explain that one for you. I am running 490whp on 780's safely according to Doug from TopSpeed, I believe the max duty cycle I have seen is somewhere in the low 80's...

p.s.- MRevolutionRed, keep your mouth shut when you don't know what your talking about, if somebody happened to listen to you and blew up there motor that wouldn't be very nice would it.

i m using 1000cc now, but for stock ECU i will go with 780cc ...

 

I prefer the Delphi ball and seat injectors sold by Precision and FIC.
