So I've been looking up injectors for my car and I've found some Precision injectors on phearable. I'll be looking at pushing probably 14.7lbs of boost(one bar) and would it be stupid for me to get some 680cc low impedance injectors over some 525cc saturated injectors? My tuner set if I got some low impedance ones with a resistor box he'd be able to set up launch control, but are those injectors just too big or would I not have a problem with them?

Btw I'm running a D15b, Skunk2 intake mani, ramhorn exhaust mani, mild porting done, and internals if that helps.

 

Bump...

 

You left out one of the more information bits. What size turbo? PSI is irrelevent for the most part. How much HP are you looking to get?

I would suggest going for something where you do not need a resistor pack. However, the 525's would not be enough, unless you have a smaller turbo putting out the 14.7psi.

Do you have an upgraded fuel pump? If not, you better look at getting one. Walbro 255 lph would be a nice addition to you set-up.

I don't understand why your tuner is saying he can set-up launch control with the low impedence. Can he not set that up with saturated injectors? That doesn't make any sense. (to me at least)

 

I don't know the specs on my turbo but I do know it's a t3 turbo, and I do have a high flow fuel pump. I'm not really to sure on how much horsepower I want to have, it's my project car so probably the most I can push out.

 

Saturday bump....
