hey guy im looking for a set of injectors for my build, and i want them to be at least 750cc, almost no company advertises an injector that big for a cavalier so from the guys who are already running with big injectors maybe u can give me a little help i have a few injectors that i came across and i wanted to know what u guys think of them and if they are even compatible, i have a 95 2.3 i will be using a H.O 086 head. Im aiming for 400+ hp

any feed back or help on this would be greatly appreciated






if it can't win a race it better win a show

I'm going to be running injectors for a cobalt...I already had my fuel rail modified to fit the stock lsj injectors so just picked up a larger injector for a lsj cobalt.

well im gonna need injectors that are even bigger and since its a quad 4 fuel rail, i dont know if they would even fit


if it can't win a race it better win a show

I got 89 lbs ones (935cc) how big do u need?

those would be low impedance injectors right, new or used, how much do u want for them, and what brand


if it can't win a race it better win a show

I bought them brand new (with a harness) for 200 off zzperformance. They are high impedance siemans. Mine aren't for sale as I am going to be running them with my turbo setup but I thought I would mention them to you.

lol oh ok, i will check that website, did u take a look at any of the links i posted, does any of those injectors seem like they are worth it,

Clicky!!!



Siemens Deka 80lb/hr high impedence injectors. Yes, they will work in our cars.




Currently #4 in Ecotec Forced Induction horsepower ratings. 505.8 WHP 414WTQ!!!
Currently 3rd quickest Ecotec on the .org - 10.949 @ 131.50 MPH!!!

This is what I picked up

89lb Injectors

i could be wrong but i was told that the 95 quad 4 uses low impedance injectors, i could be wrong like i said, but i also heard that using the wrong type of injector could mess up the ecu


if it can't win a race it better win a show

Sorry I haven't been around lately, I do still have the the 75lb Delphi's,I also now have a set of 95lb Delphi's,both sets are low impedance. You can run High Impedance injectors in a low impedance ECU but NOT the other way around,(you can but you will need to run a resistor box).

how much do u want for each set, im assuming they are a direct fit right?

Direct fit. $150 either set,shipped.

im really stuck between which too to decide, the 75s would put me right at the low end of my expectations, and i dont know if the 95s would be too big, but im definitely getting one of them, maybe someone can offer me some help on figuring out the math on this one, im aiming for 400whp in a built 2.3 h.o motor with 8.5-1 pistons

Brandon Fetter is running 1000cc's (96lb.) and making 460+ on a Dynodynamics (550+ Dynojet) using HPTuners. My personal UPinION 75lb. should be plenty for 400ish and easier to tune. Unless your going to be running e85 Ethanol...


I'd be willing to hold on to the 95lb'ers and swap you out later if it proves you need them...

yeah thats what i was thinking, and with u being willing to swap them if they are not enough for what im running makes the deal even sweeter, so i will go for the 75's, if u can just pm me ur paypal info so i can send payment, thanks
