I've done a few little improvments on my truck and want to do more. I have about eight months to dream up the perfect build on my engine and need help with it. When I start on the motor I'll have plenty of money and hopefully a decent amount of time. I leave for Iraq in the next few weeks and when I get back next summer I want a fast truck that will also be able to pull my battlebuddy's powerstroke backwards. Does anyone have any ideas?

Duramax.

Don't like the duramax. I like american engines and have experience working on the 6.5. I'm a 63B in the U.S. Army

if i were you i would look at block from someone like ronnie joe and a turbo from chicagotdp. to me that would be the ultimate combo, oh and really juiced up ip

does this ronnie joe have a website?

can a bigger turbo and marine injectors help?

yes but i dont remember what it is. pm him

ya but youll need a ic and can only run a max of 15 psi. some say going to bigger injectors dont really help unless running a hopped up ip

ronnie is a member?

ya his name is ronniejoe and i found his web site:http://www.schoolcraftpowertrain.com/

thanks alot dieselboy I really appreciate the help

no problem, good luck and keep us posted on what you decide

his engines sound impressive on his website and I've heard of most of the modifications and procedures he's doing to his engines but after I get this durable engine can it handle more boost? say 18psi or dare I say 20psi?

not sure about his engine but iirc chicago is running like 30psi

Who do you think builds the duramax?

the duramax engine is based on an Isuzu diesel

Look not so closely at the lower end of a BB Chevy or a 6.5 & then look at a lower end of a duramax & see if it looks like Isuszu or maybe GM had some influence on the design.

no isuzu designed the engine. go to google and type in duramax diesel isuzu and read some of the links it comes up with

gees is its anything like 6.5 then forget about it):h

Not that i have a good rumor source or anyhting but it appears that isuzu may have lent a hand on the heads & fuel program but then again Gm owns a good share of Isuzu since 1971 so who is really in bed with who?

I was always a big mustang fan when they had a 5.0 in them, but then the 4.6 mod motor came out and I was about to buy one until I found out from another tech at the ford dealership I worked at that most of the 4.6 was mazda. So I didn't buy the mustang I will always buy domestic vehicles. My new bride will not allow me to buy another mustang so I have this diesel truck and it's for the most part "outside of a few electronics" american. and I want to keep it that way. I'd actually thought about the duramax swap but I read the article about it being an isuzu engine and that shot that idea out of the water

Not that the duramax is a bad motor but I come from a military family and my grandfathers both got purple hearts from the war in the pacific and they would roll over in their graves if I bought a car made in japan

"DMAX was established as a diesel engine production company in September 1998 in Moraine Ohio,60 percent capitalized by Isuzu America and 40 percent by GM (now 40% by Isuzu and 60% by GM)."

I live & breath GM for a hobby & for a living but I'm here to tell you there is not a vehicle available new right now thats all made in the USA. I'm Not trying to pick on 6.5 cause I own one or two myself but if you push these things to hard they seem to turn into scrap iron awful easy. The max hard parts are made here & bosch did the injectors, My best guess is GM Had to kill the reputation for engines blowing up all over so they gave everyone the idea that the max was a total new deal but GM did & does the majority of this engine.

isuzu makes the duramax? i guess my next truck will be a Ford

I believe in the 6.2 and 6.5 motors. Being a mechanic in the Army I've seen a 6.2 run after being fully submerged in a pond and all we did was pull the injectors turn the engine over manually and spayed some wd40 in the combustion chambers put the injectors back in and it started up and still runs today. In another case one of my battle buddies hit an ied in Iraq that blew the oil pan off. He kept driving and made it to safety 5 miles away without the engine cutting off.

In relatively stock form they are fine. We also should figure out how much power it is going to take to put the hit on you're buddy's Powersmoke, if he's making anywhere near 400HP you have you're work cut out for you.

I like a good challenge and I know this is a big one. He is putting more money in his truck when he gets back too

all he has at this point is straight exhaust and a chip

What year of ford & what chip?

1999 f-250 4x4 ex cab I guess the chip to be around a stage 1 because anything else and the exhaust would need to be changed " I think"

Is Yours just a driver or do you tow with it?

it's just a driver. it's retired from towing trailers. every once in a while I have to pull people out of the mud with it but that's it

WE put a 250 HP marine pump turned up a bit with a 300HP Penninsular Turbo on a stock 6.5 2500HD & that thing runs like heck!!!!!!!!!! Don't think it'll pull very well below 2500 RPM but it is fast.

it still needs to be driven on road. On base there's alot of stop and go driving

I think I spelled that wrong but what the heck. It drives really well with those parts partially because there is little torque required with no trailer.

Not that the duramax is a bad motor but I come from a military family and my grandfathers both got purple hearts from the war in the pacific and they would roll over in their graves if I bought a car made in japan


if it makes you feel better, when you buy a duramax, 100% of the profits are going back into the United States. The Duramax is built by "Duramax LTD", a US owned and operated company with US workers in Moraine Ohio. :) Isuzu and GM collaborated on the DESIGN. Once Isuzu gave their 2 cents as far as design, GM pretty much cut them loose and bought out the design and rights to it. Every single part on a GM truck is made in the US by US workers. Except the climate control module, and Bose amplifier, which are assembled in Mexico, and the Bosch injection pump which might be German, but probably assembled in the US. No offence, but to even get to STOCK duramax power levels you will have to dump a lot of money into a 6.5.

FWIW

Every single part on a GM truck is made in the US by US workers

To bad my 1995 was built in Canada, and My wife's 2005 was built in Canada

Im not bashing here, my Dad has 29 years in with GM, but im just stating the facts

However my 2004 was built in the USA at the Fort Wayne Plant

I don't like the duramax and never will. I've seen a few of them and I've seen where it says made in japan and pakistan and all those other places that are not The United States Of America on alot of parts under the hood and on the body which by the way is a little light weight for me. I like my good ole' 1995 2500 it's got over 178000 miles on it and has had the injectors and ip changed only once in it's lifetime. A guy in my company paid over 55,000 dollars for a truck with the duramax in it and has had the injectors replaced twice and the computer once already in less than 20,000 miles and the dealership still has the truck and can't figure out why it smokes and sputters. I like the 6.5 and that's all there is to it you're not going to change that. If you're not posting something that'll help me out with my problem then don't post.

well I gave you my oppinion. You said I was entitled to my own oppinion so whats the problem here? Now heres where I could make snide remarks about PMD's, but Im not going to do that.



18:1 pistons, splayed mains, hi pop injectors, heath/kennedy chip, optic bump, intercooler, bigger turbo. The root of the issue lays with the Indirect Injection design and Stanadyne rotary pump. There simply isnt the physical capability for large amounts of fuel delivery.

I didn't mean to offend anyone. I just really like my old beat up truck. It's reliable and carries all my tools "that I need to keep my buddies cars and trucks running with " mostly fords by the way. On another note how hard would it be to put a hi perf marine engine in my truck?

www.kennedydiesel.com has some good 6.5 stuff :)

there was a website I found a while back that had all the tweaked out marine 6.5's, contact info, prices etc... Ill see if I can find it. They're all mechanical/DB2 pumped engines I think?? No electronics to deal with, and easy to get more power out of. I dont remember the prices off hand, but I remember being surprised how reasonable the prices were for the power output. Maybe 3,500-4,000 dollars for the ~300hp / ~500 ft lbs of torque one???

ben

peninsular....

hey maybe you could be the first person to put dual pumps in a pickup:D

dual pumps?
How would that work?

someone did it on a tractor puller by making custom brackets.

his engines sound impressive on his website and I've heard of most of the modifications and procedures he's doing to his engines but after I get this durable engine can it handle more boost? say 18psi or dare I say 20psi?

The psi you want to generate is only 1/2 of the equation. Remember when you compress air, it heats up, when it heats up it's less dense. Less dense the air, the less oxygen there is to burn.

Instead, figure out the amount of HP you want to generate and visit this website. Dont forgot some of the variable are going to be different like the AFR isnt going to be 12, it will be something in the neighborhood of 14.6 (iirc) Also I'd use a VE (volumetric efficiency) of 75% or so.

Looking at compressor maps it looks like a T04E-50 would be perfect for a stock 6.5....but compressors will change as you change hp output, methods if AIT cooling (WMI will drop inlet temps to below 100*F, intercoolers will drop the inlet temps to 130*F and change) The best part of changing out turbo's to a conventional turbo is that you can take your vacuum pump and vacuum system and kick it across the shop floor, and you can install a MBC (manual boost controller) and up boost via that route. (OEM uses a vacuum operated WG solenoid as you know, where as most of the industry uses the boost generated by the compressor to modulate the boost)

You've been given some AWSOME advice as far as mods to the 6.5 are concerned. Might also want to look into 4.10:1 gears or a hair lower and a shift kit. This will help on accelleration, but be advised that the 4.10 gears on the 4l80e on OEM sized tires wont go over 83mph, but will get there quick!

You are lucky you are going up against a 7.3 instead of a 6.0. We've got a 6.0, as much as I hate to say it, it spanks my 6.5 all day long in their current trims. The 6.0 generats 325hp/570tq bone stock! The 7.3 however isnt as strong nor winds up as high in rpm as the 6.0. You still have quite the work cut out however going against a chipped 7.3....

Btw - I wouldn't mention a build up of any kind to your battlebuddy, that way when you do leave him 10+ trucklengths back you can claim its a bone stock 6.5! :P :D

thanks for the info. I appreciate it and will look into it. Like I said I've got 8 months to come up with the best plan. We're not racing though we're going to hook up bumper to bumper and pull
