Injector Mods

[sparks57]

Pardon my ignorance, but I've been looking through the archive for about and hour now and have not quite found what I am looking for.



For all you guys that know about souping these bad boys up:



I have found that getting air in and out is number one. I have straight piped it and plan on chopping the pipe further. I got a higher micron air filter for better flow. I see a lot of people have "K&N" filters, what are these?



I have bought a different turbo housing.



The next basic thing is to mess with your timing.



What's next? Would it be to change out the injectors? I was told to find injectors for a higher horse-power truck. So if I go to the junkyard and rip some injectors off a 2nd gen truck... would that be OK?



I have taken the first steps, now I want to take this further... It seems like switching out the injectors is where most of you guys stop. I have a feeling anything beyond that step is starting to get too expensive.

I'm sure somebody is gonna post while I am writeing this, so please disregard any repeated info.



First of all don’t feel ignorant, you gotta learn some how. The best way is to ask (or figure it out yourself if nobody will tell you). Second, kudos to you for searching the archives. There is a lot of good info to be found with just a little digging. The K&N is a high flow gauze type filter that will directly replace your factory filter. Injectors and timing would be a good next step. The injectors will give you more power of course, but also reduces the stress on the pump. Some have tried injectors designed for a second gen and had good luck. However, I would stick with Power Wagons (Bosch 185’s) or Prince of Darkness (Lucas) injectors. These are the most popular, and work well. The PW’s are a bit “cleaner,” and the POD’s will give you the most power of the two. I didn’t see a pyrometer in you signature. That would be first.

Get a set of POD's and don't look back



2nd gen injectors will not work. Threads are different and they are meant to run at a much higher pressure than our injector pumps can supply.



A K&N is a type of oiled gauze cleanable/reusable/high flow air filter. aFe also makes filters of this type.



Cheers,

humm..... who could that be



Are you sure that it was the entire 2nd gen injector that was used and not just the nozzle? Perhaps the popoff pressure was re-calibrated?

[Old Smoky]

You know good and well who that might be .



I am no injector expert. I have heard of modified 370's in a first gen. I don't know what was done to them. I believe different nuts were used. Do I remember right hearing that stock POD's flow more than stock 370's? The 370's would have an advantage if they have more holes, and where honed. I need to start writing stuff down.

[BushWakr - RIP]

Smoky, you're doing good for an old guy ... ... . you still got a memory...

Assuming that both the Lucas and the 370's are stock (original unmodified non-messed with not extrude honed etc etc. ) the Lucas flow more fuel than the other.

Hence the nickname POD... . Prince Of Darkness



CB_'... . don't ever be afraid to ask a question... . one of the best comments I've seen on this entire board is "..... the only dumb question is the one you DON'T ask..... "



Also, I'd like to compliment you on taking the time to at least go thru some of the old posts/archives..... there's good stuff in there, in fact some of it should actually be dragged out and put back in here for some of us old farts... ... . Oh... . sorry Mike... .



BTW, who you callin a nozzle... .

Go with the PODS If you can afford them I am extremely happy with my set

 

[Wayno]

You might want to try a Big Honkin Air Filter with a Outerwears prefilter and a Old Smoky Big Honkin Air Filter Mount .

 

[DPKetchum]

Bully Dog also has a marine injector good for 40 to 42 h. p. at a great price.

 

[sparks57]

About how much do those POD's run? If I got them, would I just pull the old ones out and drop these in??? No hidden costs?



I saw those K&N filters in JC-Whitney... they're expensive, but I think I'll order one. Do you guys service them with the kit they sell?



Oh, and I did get a pyro... I'm gonna put it on this weekend.

 

[Case500D]

Hey CB,



Autozone carries the K&N air filters. Might be cheaper than JC WHitney and you won't have shipping charges. I got the cleaning kit when I got my filter, they are about $10. They work well. Injectors take 2. 5 to 3 hours to change, especially if it is your first time. You have to loosen and move the high pressure lines, remove the return line, loosen the nut holding the injector in, pull injector with slide hammer, clean the bore, put a new copper gasket on the injector, then reverse order. Not too bad of a job. PODs run about $400. Go to www.piersdiesel.com to check them out.

Holy sheep dip! That's pretty expensive! Are they really worth $400? How much are they going to give me in terms of HP?

 

[sparks57]

Ok, can someone please explain to me what all this is:



93. 5 W250 4X4/CC,Lucas POD's, DTT 89%TC/VB/transmission,3-1/2"exhaust,

16cm,28 psi/230HP,Diaphram@80%(lock collar still on,StarWheel@prestock

Timed@15*,K&NAir,IssproPyro/Tach/

TransTemp,AutometerBoost,Borgeson



I understand some of it... but what is "DTT", TC/VB/transmission", a "Diaphram", and a "Starwheel @ pre-stock". Also, what is KDP, and SB ConO?



I just want to know what all this stuff is.

There isn't much you can do on our trucks that is cheap. I am sorry to say. If you want to turn it up to what it should have been built at. It will cost so money.





DTT is the name of a trans rebuilder.



TC means torque converter.

VB means valve body in the trans.

transmission. probably means it was a complete trans he had installed.





The diaphram is the diaphram that the fuel pin is attachec. the 80% means it is at 80% of its stock max setting. I think. LOL



The star wheel is in the same place. it is also called the smoke screw. If you have to much smoke you turn it counter CCW. If you don't have any smoke turn it CW.

:-laf:-laf. . sheep dip... :-laf



Plan on $500 for most mods.



injectors, exhaust, boxes, etc.



transmission's and clutches are more plus $3-500 for installation.



Compare it to a gasser. 100hp on a small block whatever is usually $1-3,000 instead of $4-500. they get worse mileage. Ours usually gets better.



Makes you wonder why they sell HD trucks with gas engines

A KDP is the "Killer Dowel Pin". You can read all about it at the top of the "12 Valve Engine and Drivetrain" forum. The KDP can also affect 1st gens.



A SB ConO is an aftermarket clutch for manual trannies. It's sold by South Bend Clutch.



The starwheel and the smoke screw are not the same thing. The starwheel sets the spring preload and the smoke screw sets the initial position of the control cone. Check out BushWakr's and Jbolt's galleries in the readers' rigs for pictures of the injector pump.

It seems like most people stop BOMBing at the injectors. I think that the different turbo housing, the pump tweaks, and injectors will give me what I want. It seams that most people are satisfied with that. Besides, all the stuff that goes beyond the injectors are way too labor intensive. I will probably have to wait untill this summer to get the injectors though, I don't have the money. I still want to buy stacks and leveling springs, and build a new bumper... the list goes on.



One last question though: If I get the POD's... can I swap them out to a new (dodge) truck if I get one? That's and awefully expensive item just to leave it in the truck if I sell it.

Only if it's a 1st gen. The '94s and up have different injectors and injector pumps.
