Ok, I just read in another thread here that you can put in the yellow top 19lbs injectors from a 4.6L ford motor and get a little more out of your 2.5L. What are the pros and cons, lets hear it.

Jeffy,
I expect you to comment on this.  :D

Lets hear it

I found this place that sells 19lbs injectors that list them for Mustangs and 87-95 Jeeps.

Injectors by themselves will not get you much of anything... you need to know what flow rates the fule pump can support and many other things.

In my opinion all you will do is end up getting more power at a higher RPM if you start modding the engine. Since 4 bangers lack displacement the only thing you can do is spin them up to get more power. Think of it as an air pump... to get more power out you have to push more air and fuel through it = higher RPM.

edit - this is to tr to simplify things - don't want to write a book here. There are other considerations is all I am saying.

absolutely no point in upgrading the injectors, especially on a close to stock jeep. The thing runs rich already. I'm probably one of the few with a wideband o2 sensor on my jeep, not a narrowband. Under WOT it is between 10 and 12:1 afr. It should be around 13:1. Now if you have some form of forced induction then go for it. And the 4 cylinder jeep fuel pump is the same ones used on the 6 cylinder, so there is more left in the pump.

If these are 19lb, what are stock injectors?

Hmmm, I do have a 4.0TB bored to 50mm, I wonder if the Stang injectors run cleaner than my 200kmile injectors now.

What is the lbs of the stock injectors?

I just got a set of 5 off of Ebay coming. It's worth a shot.

I am thinking that after 200k+ miles that the stock injectors could be the reason for my motor running rich anyways if they are dripping instead of spraying.
For the $19 I paid for the Injectors Shipped, it worth a shot for bettter running better performing motor. :D

If it works, you can bet I will post it up.
If it doesn't work, I will stay in hiding. :lol:

Well here's my 2 cents.  I think the stock injectors are around 16lbs.  The fuel pressure at the injectors will still be regulated by the fuel pressure regulator and MAP.  The only thing that might be better is the spray pattern which would help combustion.  BTW: '95.5 and +'96 use a larger injector then the earlier YJ's.

So if that is true then it might just work because of the spray pattern. It cn't get any worse than whats in there now. It's worth a try.

I would like to tell you guys what I did and how I went to Ford injectors. I have a 92 with 200K on it. I have a 4.o TB and spacer with a bored out intake amnifold also a K&N intake. There was a post a whaile back asking about high porformance injectors. He went to the web site posted below ford injectors. So I called that place and asked him some questions about the injectors. He told me they are stock injectors for ford mustangs. I was not willing to pay 160.00 for them so I went to a junkyard and pulled 4 of them out of a ford crown vic. I put them in my jeep and the things runs great. I can hold 70 MPH on the freeway no problem even going up hill. So I would like to disagree with some of you that say it will not help. Just looking at the injectors them self the jeep injectors have 1 sprayer the ford have 4. I am able to run at lower RPM at higher speed then before. Maybe I just got lucky but for a free upgrade I am very happy.

See I would think the difference of the spray alone would make a difference like Jhcujo is saying.
I am gonna try it. All of us can do with a little more bottom end power. If it works as he says then there is proof in the pudding. Then we can say 2 people have tried it and it works.
We both have about the same mileage on our motors so I am hoping for the same result and if the pressure regulator will only give so much then the 19lbs injectors won't flood the engine it will just spray better, maybe a finer mist which we all know a finer mist makes for better throttle response and better combustion.

So what are all the injectors that will work?  I've been meaning to do this for some time now.  (more then a few years)  But never got around to do it.

From what I can tell, any yellow top Ford injector that is rated at 19lbs. I just Picked up Mustang ones to make sure I got the correct ones.
