Engine/Transmission (1994 - 1998) need injectors/ poor little stock turbo

[cluckmaster]

I've been reading up on old posts about injectors, but I've got a couple of questions. I rarely tow with my truck and its my daily driver. I've still got the stock turbo, and probably won't be in the financial situation to upgrade for at least the next four or five months. What is the biggest set of injectors I can run with my setup and not be too hot? I'm sick of not having any fueling mods. I want to eventually get big hp/torque when funds allow and hate to buy another set later. I currently cannot peg 1000 degrees w/ my #8 plate full forward at sea level, even w/ a 26' boat attached and my foot buried. I would like to be able to still drag race a Ford now and plow snow without cooking my engine but I want some freakin power!!!



I've spoken to DDP and New Era, and I guess the NE 435s and the DDP4s are too hot for stock turbo? Would it make a difference if I ran a water meth injection setup w/ the new injectors? Maybe some DDP3s and laser cuts?



Also, any I thought Buddha power made injectors, but I can't get on their website. Not sure what that's about. Any experience with these or the Mach injectors?



I definitely don't want to go with marine injectors, but any suggestions are welcome. Thanks. -Josh

I got custum edm'd injectors that are about 220 or 240 hp and then DV are done to I still have stock turbo on my truck my egts are only 675 700 driving pulling my 3000 lbs 16ft cargo trailier I get to 800 on a good hill if I maintain my speed at 60 65 that is post turbo that is with every thing you see in my sig. The timing is do to hazing at idle do to injectors and dv. My stock does good job with egts its the smoke clean up that is can't handle the greatest unless you take off with only moderate throttle.

 

[cluckmaster]

Forgot to mention that my timing is at 17. 5* and sensor is pre turbo.

You would need injectors 5x0. 022" or 5x0. 024" to make anywhere near a 200hp increase, 435's are 5x0. 018" and are rated at 140hp. I would believe your 5x0. 016" injectors are in the 110-120hp range.

There will be no injector that will help you for power if you don't have the transmission to lay it on the ground. Before I'd even consider any injector for your truck,having seen your modifications listed,the next purchase would be driveline related and worry about injectors later. Just my thoughts as without transmission upgrades your drag racing days are growing short... ... ... ... Andy



On Edit...

Hmmm...

A little bit of research here and you would find that to be a really bad statement,especially with many of us already knowing that the Marine 370's will support about anything most of us want to do. "Old Sickly" many moons ago laid down some very respectable numbers using just the 370's as did a few others. While I will agree that with todays technology there are are other choices out there,never discount what the 370 can and has done,it still remain as one of the best bangs for your bucks.

New era also edm's injectors that are the same as 370's but have the correct pattern. Make real good power and will still be drivable with stock turbo. I've seen the burnout and smile afterward of a very happy purchaser of these injectors.

Yes, I second the Transmission. You wont be doing anything if your transmission isn't taken care of. forget injectors for now. concentrate on getting the engine power to the ground. With an #8 plate you should be able to get reasonable horsepower from it. How much boost do you see under full throttle. Take a look at you fueling, I think something is not set right. 1000* egt's seems like your not getting fuel still. I have a 10 plate and can peg at 1400* if i want to, and thats with the plate in the stock position. But I don't know your exact setup so thats just my $0. 02

 

[tp0d]

I agree with NHays... I have a #10 (well, might be a #100 heh) plate in the stock position, afc full forward, stock 180s and turbo, and I can push 1350 easy while empty. You should have min of 28lbs of boost with that #8ff. I can get 38 but my w/g is blocked off. .



Something is not putting enough load on the engine, allowing it to freewheel (psst. . transmission)



Fuel is a good possibility also. . Have you changed the filter lately, and/or overflow valve? A suction leak will cause a good hp loss also.



Definetly take care of problems at hand before knowing the true potential of the engine. New inj's will just waste the fuel, which is way too damn expensive currently...



good luck

I'm pushing about 32 lbs of boost at WOT. I'm looking into a new overflow valve right now- probably going to order one from TST today and will switch out the filter at the same time. I've been getting poor mileage so I've been looking into this stuff. I really need to get a fuel pressure gauge I guess. New lift pump and lines about 1 1/2 years ago.



Believe me I know I need the transmission- just a huge cost- but I'm working on it. Trying to decide if it's cheaper to drive from DE to Goerend's and pay for the install or have it shipped here, install myself and ship mine out. I'm also debating in my head whether I need any billet shafts. I'm hoping I see a huge difference when it happens, and I am planning on waiting to put the injectors in until I get the transmission- but if I see a deal I'd like to get them now. Just wondering what I should look for. Thanks! -Josh

 

[cluckmaster]

Update- changed the filter today and the overflow valve should be here from TST early this week. checked the fuel mileage the other day and got 13. 5!!! Somethings definitely screwy here. Like I said, I changed the rubber suction and return line about 1 1/2 yrs ago and changed the lift pump at the same time. Hoping the filter and overflow valve do the trick- bring the mileage back up and get me some power as well.



How often do the hard lines to the tank itself go bad, and the hard part of the return line from the overflow valve to the rubber line? What do you guys replace them with?



Any other suggestions? Thanks. -Josh

Lots of people have had fuel heater problems. (air leaks) I had the big allen bolt loose that holds the heater up cause a airleak/power loss.

I believe my Gov arm stuck for like a month, Not giving me full fuel/power. It fixed itself. Truck took off like It had a stuck throttle

 

[pwerwagn]

Ive had problems with the pre-screen in the pre-heater plugging. Low end was there, but power was very linear. Boost was still up there as well, just didnt pull much past 2,000 rpm. Cleaned the pre-filter and it was game on again.

 

[cluckmaster]

My fuel heater had a leak about a year and 1/2 ago, so we just took the sucker out. Still gone. Also cleaned the screen at the same time. Just went out and changed my overflow valve about ten minutes ago, so I'm gonna check my mileage now I guess And see if I get any higher temps.

Can anyone tell me of the pros and cons of the Marine Injectors? Are the 370s the Marine Injectors? I'm getting mixed signals regarding the Marine vs the stock. Your help, please.

 

[pwerwagn]

The 370's are marine injectors. They have the wrong spray pattern. This will cause a haze at idle in some trucks. That is the main "con" of these injectors.

The pro is they are CHEAP!! Cheaper than stock replacement 215 injectors in most cases. And they make some pretty good power as well.



If you can live with the smoke at idle, they are the way to go.

370's are the basic name for marine injectors. Our 370's are not marine injectors. We edm the correct spray patteren in injectors for the trucks we just used the 370 name because that is what everyone knows to figure power and hole size. If vendors advertise 5x12 or 5x18, 75% of the diesel world have no idea what you are talking about. But just about everyone knows what a 370 is.

Thanks, Jeff and Chuck - that's what I needed to know; they're going in today.

For just about the same price, you can get the EDMed 370s from New Era Diesel. They have the correct spray pattern for our pistons so less wasted fuel, better economy and little better power. Also, keep your eyes out on classifieds for used DDPs or other EDMs. All should get better mileage than marines. -Josh
