Twin Turbo 6.9 IDI Build 

its pegs long lost son, yer stunned!

Let this guy cook.

this man's a young two legged Peg with a 6.9 instead of a 7.3, send er to the ketchup and don't forget the beer!

When you ran that engine with the up pipes open, it reminded me of when I was a tank mechanic in the marine corps. The engine was a 1790 cubic inch V12 contiental twin turbo diesel. We would pull the engine, set it on the ground, run jumper electric and fuel to the tank, and run the engine on the ground. Standing right between the two turbos. pull the throttle wide open hahaha. It would rattle your guts. We were 20. We didnt need hearing protection either

That hackjob has no right to sound as cool as it does. That's amazing. I need to get mine built; I have an '83 engine too. ARP studs right away, and the inconel valves from a 7.3 should hold up to the ChinazonBay ball bearing GT35 quite well 😁

Zip ties n bias plies 2.0. Love it 👊🏼👌🏼

I like it. Im running 40 psi with a s366 on my build 7.3 idi. Its a blast. If you have any questions feel free to hit me up,

idk, that's the quickest IDI I've seen

Boy would you just look at this mouth breathers work I'm subscribed now don't won't to miss a thing

You idi guys are your own special breed. lol 15 yrs ago I bought a idi with cracked heads and a banks sidewinder. Bought a used set of heads. and a few days later. That Idi was actually rowdy like a tuned 6.0 psd kind rowdy. But those heads only lasted that one weekend. Lol I dunno much about those old motor's but most likely they need that high compression to help with cold morning starts. If you get that compression down by porting the bowls and delip it will allow you to pull some more timing and make some decent gains Would also need a fast starter maybe modify a 6.4 or 6.7 I wouldn't worry about to much boost. Boost isn't the problem its the high temps that kill diesels from over fueling. Boost is a measurement of restriction. But it also a multiplier of hp. get a good exhaust temp gauge. try to aim the stoic air fuel ratio around 20 to 1. Then should see a lil over 380-400 hp at around 15-20 psi. I wouldn't go anymore on a non-bed plated bottom end.

The power is all in your fuel pump internals and settings. Doesn’t matter how much airflow potential, you need fuel to build exhaust gas pressure to build boost to make that airflow potential from the turbos for the power you want. They’re large turbos so need a lot of exhaust gas pressure to build any meaningful boost

She’s wayyyy quicker than my buddys ol 6.9.. and that was a healthy one with shorter gearing. She’s woke up pretty good!

I have an IDIt for my overlander rig. Big turbo gtx3582 Intercooler New injection pump E lift pump New injectors 3” down pipe 4” exhaust Head studs V banded intake It’s definitely not “fast” but speed isn’t something I’m interested in for a 13000 lb rig. I have been extremely satisfied with the engine. It’s simple, tough, easy to work on with plenty of torque and the sound is wonderful. It’s a great engine for what I’m after. I’m glad to see all of the people interested in the platform. They are a ton of fun Great content

That's a pretty awesome turbo setup, I want to do something like that to mine. The factory turbo system is horrible. I will tell you this though, 15psi on an IDI will beat a stock 7.3 powerstroke, but only if you give it more fuel and more RPM. The factory pumps are super limiting. I have the R&D 90cc pump in mine as well as aftermarket valve springs, a big cam, and big injectors, and it makes a huge difference. Having full power up to 4200rpm is awesome.

I love the destroyed knuckles through half the video

All that matters is that it cheeches and makes turbo noises, miiiiint! 😁👌

I love my 7.3 IHI. Thing is solid😂 only at 200k and its never had anything more serious than a water pump leak. Been thinking about intercooling it and throwing some fuel and a bigger smoke whistle on it

We had an OG 6.9. gotta love the international diesel. this thing will run with nothing more than a couple of power wires running to the valve on the injector pump. No HEUI, no electronic bs, Just fill it full of your favorite lamp oil, & a way you go. Ours was an actual fire truck with a heavy duty alternator. You would have to step on the gas to start the alternator working, even after the engine was runnin. Gotta love the 6.9/7.3 IH IDI. (I think the only difference was a head bolt or somethin.)😮😊

Love it! Makes me ALMOST want to do a resurrection ofmy 1990 7.3 Idi its been up in blocks since 2014 lol lol maybe oneday this summer we will see

You get an A for effort, great way to a starter twin turbo project.

Cool project, I wonder if you would get more response from it by going to a pair of smaller turbos? Say like 2, 2.5L Chrysler units, would get all the same cool twin whistle but being smaller they would spool faster and make same boost pressure on there stock waste gates. Really enjoy the video, keep working on her, I’m intrigued

Still the fastest brick i've ever seen. It may not be stupid fast, but that sound combined with the get up and go just makes this awesome

OH RIGHT ON! 🇨🇦 She rips now! 12 psi is plenty. Turn that fuel up and the boost will go up too.

Okay, I was letting you go off, then you showed a t100 for an example for the heater crap, subbed from Texas!🤠

doing see many people doing stuff with these ideas. i wish there was more content like this keep it up!

IDI's are my favorite diesel engines. Especially the 6.9l. N/A, they're slow but just bloody well run forever with regular oil changes.

The R&D cam wakes IDIs up. The stock cam just fights boost even turbo from the factory. It's the bottleneck. It even really helps NA engines.

Your stunned brother making ol PEG PROUD THO🤙

I have twin hx35's on my 7.3, that I build to custom spec. What I found that works for boost starting at 1500rpm on up, is a 50mm compresor wheels and 10cm turbine housing. Your turbos turbos have a tad bit bigger compresor wheels, that makes it slugges to about 2000rpm and is what I found with the 54mm wheels I started with. Another note is those turbos you got, would have a better spec turbin than I have but the 53mm compressor is going to have an even harder time to light off because its smaller. So if you can get a smaller compressor wheel around the 48-50mm size and a matching housing, you will be able to get those to light off better.

Cold start then mash the pedal.. 🤘rock n roll.

Now this is bad ass. Real hot rodding Nowdays hot rodding consists of the most expensive engine with the most expensive add ons. "Cheap speed"

Love your style buddy

This video made my day yesterday, good content. Excited for more

This thing actually responds a lot better than i expected, I thought it'd be a laggy turd. Might be better, or at least on par with the tp38(obs 7.3) turbo i had on my 7.3. That was doing 15ish psi, maybe a little slower to get there. Good video!

Loved the Great Escape reference.

Pretty good editing and quality of video for having under 1,000 subs props

Gotta love these kinds od vibes man!

You will get wherever you want though, you will get there

That tech is dope as frig lad, 😎🚬 Yea got a spot where an east coaster can find one 😆

If something, it sounds badass. Like mercedes twin turbo diesels.👍

subbed, this kids the next ZIpTiesAndBiasPlys for sure. that 896 going to 896k no doubt. (don't read to much into the liked comments they are quotes and reference's from another guys youtube that he moved over to patreon due to censorship lol)

Single turbo of that size would work great.

pro tip, add a ton of lights in your shop, 2x of what you think you need and paint the walls white, with cameras more light is better

You need a upgraded DB2 pump, injectors and a cam swap if you want to go deep with it. I used to participate on a diesel site and we ran all kind of scenarios. Look up Moose Pump, Baby Moose pump. Adding air and no fuel just makes the old girl run cleaner, and we don't want that. Colt or Bullet can make a cam for the IDI.

Glow plug Tip swap out for part number AC-12g / glow plugs .[[4.3l Oldsmobile 1984 diesel ]]]part i think but it works and no timing box needed just a 12 volt ford starter solenoid as the relay switch i did mine that way best thing i ever did no more dead glow plugs

This setup with one of those turbos Wastegated would improve both spool and boost, one diesels We rarely need the flow of twin turbos, We need the boost to force flow, having both in a compound setup would be ideal to make a lotta boost 60psi+

Definitely Peg vibes. Great video.

Neat! Realistically,these engines can take around 8 PSI long term, because they don't have upgraded head studs, beefier pistons, wrist pins, larger compression ring, intermediate ring, enlarged ring lands, and an upgraded oil cooler like the later turbocharged models, which also have a much lower CR of 18:1

They'll take more boost than everyone on the internet wants to say. Kind of like the 6.5 guys saying 15psi will split a crankshaft in half. My 6.5 has been running 25-30psi of boost for over a decade towing and tons of miles on it. No head studs or anything special. There's a company that does performance DB2 pumps for the 6.5, 6.9, and 7.3 and they're fairly affordable. You won't make crazy power but it'll bring it clear of the gutless turd category.

Shoooooot that's gotta be one of the better running 6.9 I've seen. Usually they scare ya trying to merge on the highway.. 14 psi isn't bad. Anything over 6 is adding power.

This man watches zip ties n bias plies I see… a fellow man of culture!

You don’t want to make a lot of boost with those turbos. Giant heat pumps after about 10 psi. Actually might be ok with only 4 cylinders feeding them. This is something I would build 😅 oh it looks like you have a waterbed for front suspension 😂

Love what you're doing. I have one serious question...what turbos are those? I ask because they look like GM 3/4/8 turbos. All of them are slightly different from each other. All of them suck. Their drive ratio is like 2.5:1 and they max out between 8 and 12 psi. At full throttle on a GM 6.5 diesel. An actual good turbo option would likely be a cummins HX35. Even stock it is WAY better

Im probably the only guy who wants an old 6.9 ford i love those trucks

This is great, like a younger version of zipties&biasplies.

I can’t wait to see it build 28psi and launch a cylinder head into orbit

Rowdy af

So you added more air but you need to add more fuel to make power?

You can take every thing from the 6.9 and bolt it to a 7.3 idi i did in my 1987 f250.

HELL YEAH BROTHER!!

Fuck if this thing were intercooled and had bigger turbos it would be nuts

Two legs, two turbos MINNNNT

sounds rad!

Impressive, you should put out more IDI videos. Subscribed

Holy fuck bro them welds seen better days, if you want some weld tips lmk

If we get this guy piston as much as zipties then we’ll be golden

Needs more fueling. My single ats093 with just a 90cc injection pump hits about 16-18psi on a steep grade (removed the wastegate vacuum hose).

You can't "turn up" the factory pump enough to make dual turbos do much of anything on the IDI's. If you want real power you need to either buy or rebuild your pump and enlarge the internals in the pump. There are places that you can get that stuff. I think the factory pump flows something around 80-90 CC or something like that, been a while since I messed with these a lot, however you can get more than double that out of those pumps. I put a 110cc on my 7.3 Turbo IDI before I sold it. If you are going to put two turbos on a diesel like that and want to get more power you should put them in a compound arrangement. That increases the total boost assuming you have the fuel spin them. I got myself into this trouble with my Turbo IDI which I bought with a bad turbo. I bought a turbo that I was told was a direct replacement only bigger. The asshole I bought it from saw a NOOB a mile away and cheated me good. The turbo was bigger, a LOT bigger and even with the 110cc pump it would produce about 5psi of boost if you were going up a hill with your foot denting the firewall. Those engines can be made to put out decent power 350hp 600torque but it's not cheap. You will spend more getting that amount of power out of an IDI than you would if you bought a 5.9 and the parts to get it to the same power. Personally I liked the IDI's but they aren't powerhouses without a fair bit of cash and I believe they have a lower ceiling than the 5.9 unless you retrofit a P-pump to it. Now if you want to spend 10-15k on a pump and retrofit the heads to accept the Cummins injectors along with the powerstroke rods and pistons you could probably push the 7.3 into 4 digits or at least close. Don't know how long it would live there but it's going to cost you 20-25k on the conservative side. Personally I would upgrade the pump to a 120-130cc pump, head studs, decent turbo, and intercooler, and let it live at the 275hp or so you will have there.

Badass

E for effort!! But yea you need to add fuel. I’ll be night and day

By chance does your dad have a horse mask and a wooden leg???

15:20 For science, of course

Yer stunned Willard

dont lie, you know you laid those god awful welds on those turbo exhaust pipes 🤣

It’s Pegs long lost son!

A like purely for the great escape reference

nice

Great video

Fine. I’ll follow

I hate the idea of pushing a 6.9l IDI more than 15psi max just for longevity. No boost is definitely the better deal for that, as they're overbuilt from the factory. I like that Hypermax, Banks, ATS and now a new IDI support company offers bolt on turbo kits, I would only build my own completely remote mounted turbo kit on this and my 300I6 Bullnose rigs.

its still old fuel? untuned? maye she still gots MOAR!! the rpms, dont let em DRAWP! more beefy clutch launch in gear TOO! im an 83, good year keep er GOEN!! FUEL: MORE SKWERT AIR: MORE KOOLED EXHAUST: MORE O2BANDED HEADS MORE TITER INJECTION MORE H20 EYE-D-EYE CAPN

How did they make it so gutless?Even a 1.5 euro diesel has more guts

sounds so fucking good

I’ll say that gets with it for a idi!!!!

Pretty hard to judge usable power in the snow right?

Idk a 7.3 with bigger hpop,injectors,turbo on a hot tune makes a ton of power....it's not a lp5 Duramax but it's also a lot simpler to work on

Two words. Quad turbos

13:00 am I the only one who notices the header glowing😂egts never heard of them

I had a 86, could not pull itself out of a puddle..... I do miss that old truck thought, could seat 6 people very comfortably..... will hit play now and find out what happened.....

Damn! Do you have a wooden leg?

Almost looks like some southern berta landscape there bud. Cool build! Sub'd for more shenanigans!

Could have had more power and no hole in the hood, but... "Like the way it sounds, so i'm happy. " Boy, let me tell you something, you about bright as 2nd generation dodge ram headlights.

Canadian Humor ? Eh ? Trucks Mint & Righteous.

What’s a idi how about more shots of the vehicle?

Miiint 👌

I daily a 3rd gen cummins, I gotta say... I FEEL ATTACKED AND I DONT HAVE THAT MANY TOOFS! Also, 33psi makes ma clutch all slippy

Ive owned several 7.3 IDIs one was even a factory turbo truck from 94 and they are reliable but they are well past their prime every hose is always rotted the fucking tank valve is always fucked and sucking air and the parts just arent available anymore so you have to use "universal " parts i have moved on all the way past the 7.3 poweratrokes i had 2 of them nothing but trouble every time i replaced something it would fuck off some other way so i finally gave up my life long commitment to ford and bought a gas GM after having no troubles at all from them i bought 2 duramaxes and now i actually get miles per gallon instead of gallons per mile and still make 500hp backed by an allison trans im a diesel mechanic and always swore id never have anything GM but ford has just gone to hell in a hand basket

As old peg says, pump it with your half good leg lol.

Man that sounds good lol

needs more duramax or cummins but sounds good so thats 80% of the way there
