87 t1 injectors in a 3.0

[neontj]

will the old turbo 1 injectors fit in the 3.0? i read it on here http://www.thedodgegarage.com/ about half way down are they a direct fit and plug in and if so would it be worth doing on a 95 lebaron with a c.a.i. exhaust, ported intake, 180 tsat, and bumped timing with milled heads and diamanite cams? thanks for the help. im not worried about the gas mileage as it already sucks at about 22mpg highway.

if they're from an 87 they're not big enough(27pph). You need the later T1's from the 2.5, also the same as the 2.2 T2's(32pph).

why not aren't they bigger than whats in there now? but they all are a direct plug and fitment right?

ARE YOU FREAKING SERIOUS?????????

Ok, not to sound mean here. But you leave mo no choice but to do some schooling, since you haven't done enough research on the fuel system and it's controls of our beloved 3.0L equipped vehicles.

There were two types of fuel injectors used on the 3.0L motor. Low impedence and high impedence. The low impedence injectors were used on the early vehicles. And the latter ones got the high impedence. And since you seem to have a 1995 3.0L, you will have to use the high impedence injectors, or you chance burning up the injector controllers within the pcm by running too much amperage in the circuits. The turbo 2.2/2.5 injectors are low impedence. So, I can only recommend use of them on the older cars.

Now that I've said my peace on the difference of the injectors.... Lets talk about why we would use larger injectors. First of all, even with all the bolt-ons you're planning(or have installed), I cannot recommend anything but an adjustable fuel pressure regulator. You're stock 19# injectors have enough flow to last you to 200-220hp. And you won't be making more than that on a NA SOHC 12v motor with a stock pcm. The only way I'd ever suggest installing larger injectors on your car is if you are installing a form of forced induction. Whether it be supercharger, turbocharger, or nitrous; you will need the flow of much larger injectors ( or auxiliary injectors).


Now, for any and everyone who puts thier eyes on this post.............

Please suscribe to the chrysler3literv6 group over at yahoo groops. And SEARCH the archives!!!!!!!! Just about anything you can ask about these motors have been answered over there. And I don't see many of those individuals left in these forums.

Just wait until I become really upset. I'll start telling people to install crap on their cars for no reason at all. And they'll love me for it!!!!!!!!!!

thanks that is why i asked the question because i figured if it was a good and easy up grade then just about every one and there brother would've had them and someone would've asked this question. thanks for the info i didn't know that about the independence of the injectors being differnet. but could i if i really wanted to swap over to the older style pcm and the injectors would i work with my harness and my security module too. thanks and sorry for the noob questions.

It wasn't you that got me upset. It's the fact that you didn't state that you were going forced induction and someone had stated that 27# injectors would be too small.

And by "impedence", it's the resistance of the injector. If you take a low impedence injector, you'll most likely see 2-5 ohms of resistance. A high impedence injector will be between 10-16 ohms of resistance. Take, for example, a honda turbo upgrade. They will install DSM injectors, because they're larger. But they have to install resister blocks as well. So, they don't burn up the ecu's injector drivers. But, they (honda owners) have a way to alter the programming of the ecu to compensate for the larger injectors. Where as we do not.


I should have put a smily at the ending statement. I guess my humor is too dry for internet traffic.



But, in all honesty, I don't see any reason to install larger injectors on the car, if you don't plan on adding boost or nitrous. Just get an adjustable fuel pressure regulator, if you need just a little bit more fuel for the modifications you're running.

And just for the record. I was running exactly the before mentioned modifications on a completely stock fuel system without any issues. However, I gained an estimated 5hp when I installed my adjustable fuel regulator.

I only am throwing up about 5 gallons on your post. Wink threw up 6 gallons.
plus you can probably flow more then 220hp worth of fuel if you go really high base fuel pressure.

When is see someone making that power n/a then Ill agree they need more fuel. Chris's aquired "lozier" car makes that power but its got a racing motor built in austrailia. Its not just a few simple boltons.
