injectors

[wht2002gt]

hey guys I have mods on the motors and im looking to get some injectors.

is it worth the money, what size, and what brand. Should I buy from jegs or

is there a cheaper place that you recomend

[Kiljosh]

In order to really tell you the size you should get or if you even need them, we're gonna need some more info.

What mods do you have done to your gt?

[wht2002gt]

I can't tell you everything right now but I will try.

accufab intake and plenum / cold-air induction / long tubeheaders / chamber mid (H-Pipe) / magnaflow mufflers and tail pipes / plasma ignition booster / underdrive pully set / i think thats it I can't remeber and this weekend tihnking about getting a predator programmer ( if you think its worth)
and depending on taxes p.i. heads

[all8280bcc]

if you get head go with a set of like 24lb but you wont REALLY need them but hey every bit counts and i highly suggest the tuner just got mine for xmas and i love it.

[wht2002gt]

When I get the tunner any suggestions on how to tune or is it explained in the manual

[Kiljosh]

Depending who you get it from, im pretty sure that theyll include a tune on the programmer for your car. I would go with one of them if you have never used a programmer before.

I don't think you'd need them unless you had either a power adder(nitrous, turbo, sc) or a set of aftermarket or port and polished heads with a different cam.

exactly.

unless you have a power adder or lots of naturally aspirated goodness, the stock injectors can keep up just fine.

the only time you need to upgrade injectors is when your duty cycles are close to or over 100% duty cycle. youre not even close with minor bolt ons, and even with VT stage 2 cams and heads, youll prolly be fine with a nice dynotune.

[wht2002gt]

so another words i should save the money i was going to use for the injectors and buy the p.i. heads from jegs. and do you know what size cam them have

[Thomas91169]

PI Heads have PI Cams if thats what youre referring to. cam specs are those from a 99-04 GT, exact duration and lift escapes me at this time.

without any peripherals to read whats going on, you really are limited to what you can "Tune" with a handheld. you need other devices to tell you what the car is doing, where its doing at, and then use that information to make changes.

If youre ballsy like i am, you can just start leaning out the fuel and adding timing till you get predetonation (usually heard by a pinging) and then you have found the "Edge" of the tune, and then add some more fuel and take a degree or two out of timing to keep it on the safe side. but you have to know exactly what youre feeling and listening for. Ive tuned my own DSM and many other buddies with DSMlink, i have learned to tune by "Feel" and use the information provided on my readout as a backup, most times during a 3rd gear run i can feel when timing is pulled due to knock, or where i can add timing, or when there is too much fuel (the exhaust tone goes from very smooth to choppy or defined). then again, ive been doing this for years, i can have my buddy start the run, close my eyes as hes running up through 3rd, feel the different sensations, and when i open the laptop i already know what the graph is probably going to look like and where i need to make changes for the next run.

hey if u have an 2002 u already have PI heads, if u r injector caps r a pinkish color then there 22lbs

[96gt226410]

As far as aftermarket injectors, I have only used Ford Racing 24 lbs. I've used 2 sets of them and they've always lasted until I got rid of my car and worked great.

Not sure on the power output but it will work you might need minor tuning to get the full power out of it

Hello, new to site. I posted an intro in the intro section.

As far as injectors, You really don't need them with just bolt ons. Just get a good tune. If you plan on going FI in the future injectors are a must. I would wait until then if you plan on it. They usually come in a s/c kit.
