injectors
 
Anyone kno a good upgrade injectors for a 95 2.5? Need replace them

flatline 02-21-2012 06:23 PM

the ford 4 hole style. there 19lbs injectors. check out 5.0 motor sports, I just bought from them for a 4.0. you can also use Neon injectors. forget out of what year.

DasfieldmarshelsYJ 02-21-2012 06:56 PM

Would the 4.0 injectors work on my 2.5?

flatline 02-21-2012 09:12 PM

I believe there the same injectors. from where I bought them they list as the same part #. you can save money by using ford injectors from junk yard. any ford yelow top from 90's 4.6 or 5.0 motors. but why replace old injectors with old injectors? just going to the ford style four hole, which is a bosch injector helps.

Thank ya flatline

How do the ford injectors work? More power? Fuel mileage?

flatline 02-21-2012 09:38 PM

stock jeep has one large hole to pass fuel. Ford has four small holes, so in theory it has a better spray. my experience with junk yard ford yellow top 19lbs injectors is it gave better throtle responce at low speed. New injectors gave that and now I can accelerate in 5th gear again at highway speeds.

Just got 8 from a mustang with 30000 on em

Pop them in, they provide better atomization of the gasoline, creating a better burn pattern inside of the cylinder. Since the computer has a preset mixture ratio at WOT that leans it out a bit, the 19lb injectors spray a bit more fuel in to keep the fuel mixture at a more perfect level, giving you a bit more power.

At best they add 1-2hp and improve throttle response. Couple it with some other mods and they really do sing well.

I got bouch 4 hole injectors off of eBay for 99 bucks shipped.waiting on them to get here so I can fire up my new 4.0

Would I need to use a richer gasoline?

denisbaldwin 02-29-2012 08:51 AM

Does anyone have a ford part number on those injectors?

DasfieldmarshelsYJ 02-29-2012 09:53 AM

When I get them ill look

What on earth does that mean???? :confused::confused::confused:

"Richer" or "Leaner" are terms used to describe the amount of a combustible substance there is in a given space. Your computer controls the precise mixture of air and fuel inside of your engine based upon temperature sensors as well as the O2 sensor. Running the ford 19lb injectors causes the engine to richen up just ever so slightly at WOT, creating a more perfect stoichiometric ratio. Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers, or basically the mixture of fuel to air inside of your engine. 14:1 is a perfect mixture setting of air:fuel inside of our engines, but when the computer senses the gas peddle being at the WOT position it changes that mixture to something more like 14.15:1 air:fuel to keep the engine from detonating from excessive fuel.

The 19lb injectors solve this WOT lean condition as well as creating a better atomization mixture inside of the cylinders.

I ment like higher octane

denisbaldwin 02-29-2012 03:27 PM

You guys sold me. I found a set of the 19lb injectors this morning (on eBay, set of 8 used for $30). Even if half of them are clogged/bad/etc, I still have a good set for my 4-banger. In addition, I bought new O-rings, Pintle Caps, Seals & Micro Basket Filters to freshen them up before installing. Ran me another $10.

DasfieldmarshelsYJ 02-29-2012 03:39 PM

Nice where ya get the o rings n all that

NAPA. I called up the local Napa place, told them the type of injectors that I had and they sold me a complete set of 8 rebuild kits.

No. The octane rating you use for your engine is based a lot upon what the engines compression ratio is. Stock compression engines can run 87 octane perfectly fine. Higher compression engines need higher octane gasses. Running a higher octane gasoline in your Jeep than 87 can actually cause issues such as power loss and decreased fuel efficiency since higher octane gasoline's tend to burn cooler in our stock compression engines. Sounds great, a cooler running engine, but your engine is designed to run its best on 87 octane at pre-set temperatures.

It is never based upon the fuel intake or exhaust system.

I would clean them regardless if you think they are good or not. I can tell ya an easy way to do it if you want :)

Ibuildembig 03-02-2012 12:56 PM

Mustang v8's have them, orange top 87-95 Ford

I do. Here's what I bought.

Bosch # 280150943, also ford part#0-280-150-717

That said, any of the 19 pound yellow top Bosch injectors should work. There are about a half dozen parts codes corresponding to those injectors and I've researched many different part numbers that work. From what I've read, as long as it's a Bosch and a yellow top and rated at 19 or 22 pounds, it should work.
