im building up a stock ls. im looking to get around 250whp with my turbo set up, and one of the last things that i need are injectors, i was wondering what the best injectors i can use would be?

i've heard that stock injectors from a turbo eclipse or talon would work perfect, so im just wanting to double check and see if there is a better option. thanks

 

i though rc 550's were great and will work for that hp plus some

 

beat me to it. 550 rc's

 

what is the max hp for 550's? (just in case i want to upgrade)

 

i used them for 270whp, i went a bit larger for 325 although many do use them for that much or even more.. its good to go oversize and not tax your injectors with high fuel pressure and duty cycle. my car revs to 9k so higher revs also kill the duty cycle

best suggestion? get largest ones you think you will need to use.. i'm up to 630's and it still idles like stock and i will be upgrading again.. at least when you buy them new and the right brand you get some resale value..

 

quick fuzzy math on rc's site assuming all is well with the engine and tuner:
i got 350 crank with 550 +- so 300-315 ish

 

alright thanks guys. so 550's will do me well until money flow picks back up and i upgrade. cool

 

OR for about the same, 750's can be had. they are still saturated and leave lotsa room for growth. just food for thought.

 

i heard that if i use to big of injectors that when i go to upgrade and need to adjust fuel flow that the injectors are easily messed up, due to too low of flow.

is this true?

i would love to never have to upgrade my injectors but i dont want to waste money or increase the chance of messing up my motor.

 

well never upgrading injectors comes with never wanting more power he hee. as far as the first statement i have never heard that.

 

alright, well ill have to look into to it further to double check. cause with the turbo and the rest of my set up the only way i would be able to increase whp with out over boosting would be some motor work. so if i never had to change injectors it would be ideal. thanks for the input

 

i use r.c and precision both work well

 

i have rc 750's in my stock block stock head b16 and they are fine. i am only looking for 300whp but i figured i will want more later so i just went with the 750's

 

I use Injectors from an EVO 8 They are rated as 560cc but actually flow ~600cc, They are great injectors and can be found for a pretty good price.
