2.3l diesel info

[jeff115]

i found one for a good price. are they reliable? are the injection pumps easy to play with? will they stand up to a little extr power?

 

[jeff115]

bump does any body know about them? i cant find any info any where

 

[dangerranger83]

The injection pumps are electric pumps and cost an arm and a leg to replace. They are good for gas mileage though, does it have a turbo on it, some do and some dont.

 

[jeff115]

i think it does its the one with the mitsu and i think they are turbo but the perkins are na.
i wonder if you can use a resister like the 7.3's

 

[dangerranger83]

I will say that if you try to mess around with the pump just remember the pumps cost anywhere from $500-$800 bucks to replace.

Why to want to play with the pump, to make it smoke more? If thats the case, the ranger isnt worth doing it to.

I've only seen 2 diesel rangers in my life and I wish I owned one, even rarer are the 4wd ones.

 

[jeff115]

no not looking for smoke just alittle more power

 

[dangerranger83]

More fuel isnt going to give more power on these. If it doesnt have a turbo, then turbo it, add an inercooler, or or bigger turbo.

 

[jeff115]

have you had verry much experience with diesels? more fuel will provide more power. add some more air with the extra fuel you will gain even more power.

I don't know much about little diesels, But I know when I had a 87 Volvo/White with a 315 Cat in it, I turned the rail pressure up and all I got was worst fuel milage 3 to mpg, and black smoke from both stacks, and of course after idiling all night for the heat/air to work when I first reved the engine it would blow raw fuel out of the stacks and was really blackish grey, when I turned the rail back down my fuel milage cam back to 6 mpg, and it didnt blow black smoke anymore.

that was also a manual pump.

 

[jeff115]

ive owned a 94 dodge 12valve and with a little tweeking on the injection pump and nothing else stock turbo you can more than double the power.
i have a 98 vw bug with a 1.9l diesel i put bigger injectors in it and messed with the signal that goes to the pump with stock turbo i can eas into the throttle and the new clutch cant hold the power.
i have an 03 dodge cr with big injectors, big injection pump raised rail pressure and i can eas into it and it will start a big smokey burn out at 50mph

i know for a fact with no other tuning but added fuel a diesel will gain power, it can gain way more with added tuning and air but to say adding fuel to a diesel engine wont increase power is kinda funny

 

[Robert_1967]

Like I typed, I don't know much about the little diesels, Only little about the huge one's and the old manual fuel pumps on Cats where the easest to play with, On the Newer Engines, Cat/Detroit/Cummins, with all the computer items in them, you can use the hand held comp, and turn the pressure up, and the computer will also adjust the air pressure from the turbos too.

But on the old big trucks just turning the rail up didn't help much, unless you put a bigger turbo, on it, or shut the waste gate down a little to get the pressure up.

 

[jeff115]

i dont really have any experience with the big diesel engines but i am using a turbo off of a cummins n14 on my 5.9l truck

 

[Bryan22]

there is no arguing that more air+more fuel= more power. end of story. Only thing i'd worry about is since these trucks are so rare, finding parts might be a problem. I wouldn't push it too far without looking into things a bit more. melting a piston on an extinct engine could mean the end of the truck.

2.3 is a mitzu turbo diesel with an overhead cam and a timing belt, not sure why somebody said the pump was electric. distributor style injection pump. not a great motor but adequate for a light little truck, I wouldn't recomend modifying the fuel system or the turbo as these are pretty hard to find parts for. aluminum head too. this motor also came in the D50 dodge pickups(made by Mitzubishi) around 95hp

a 2.2 mazda N/A diesel was available, but it was actually built by perkins in Japan. It is a bullet proof little engine with a cast iron head, cam in block and lifter/pushrod/rocker design. also getting hard to find parts for.
only around 65hp

unless you know your diesel engines, and like working on them they should be left alone. a little knowledge can be dangerous

big diesels and littles diesels are no different. In a diesel you have to change fuel timming, fuel curve, and fuel delivery amount. This is a lot easier to do in newer diesels because the injection pumps are computer controlled.

In strickly mechanical style fuel injection pumps you need to change the metering valve or metering mechanisms actually in the pump or the injecotr. Timing can be changed in the same fashion or by turning the pump if its gear driven.

All that said I know nothing of the ranger diesels.
