I have a stock 05 Dodge 3500 4x4 diesel 6 speed manual long bed dullay and haul a large truck camper and 5 th wheel and was told a 64 mm turbo and this 5.9 is a HO motor 325 ho so what would you recommend an it’s 152K still has factory injectors water pump alternator fan and even still the intercooler that’s plastic and no problems so what would you recommend for turbo and going to put bigger sticks in it and no runner ?

those 8.1s are good motors, only thing i really hated compared to all my diesels is you definitely feel the difference in torque. i dont honestly think you will ever get a gas motor that compares to a diesel when towing and working them

Damn my TCM went out 2 years ago in my LMM and I got one from Ryan’s diesel in Wisconsin. I paid $660 bucks for it with a lifetime warranty. It only took about 2 days to get it in Louisiana where I live.

The amount of people selling their factory turbo as a "stealth" is alarming.

I don't know that diesel guys hate the 8100. It's the closest thing to a turbo diesel in gas form. What they hate is small block V8s that have to be wound up to do any work. With emissions regs where they are and turbo diesel complexity and reliability where it is, I guarantee there are a ton of diesel guys taking another look at gas.

Im building a lb7. Im planning on a compound turbo system. Im using a lbz block, balanced rotating assebly and thinking about the cast iron heads. Looking to get above the 700 to 1000 rear wheel horsepower range. Looking at yhe 14mm stroker injection pump with the supply pimp attached to it. Now the compound turbo kit. Looking towards the s480 with one step up over stock turbo but which one? This just a project ive always eanted to do. Any suggestions?

Does this void warranties?

Allison is making engines now? Cool!

Great advice!!! Where are you located? I really want to get my 2004 2500 gmc truck running right!

Until u get rid of the egr that destroys the engine u have gained nothing! Doesn't matter how much power u have if your truck it sitting with egr issues!

They already have 450 and now 500hp frim factory. Why mess with it and piss your warranty?! They need more vgt braking like cummins not more power

Bad ass giving me some more reason to look into a 20+

Love to see the str vs pdd aggressor 60/67

P026D is still on. Truck runs great. Bought scan tool and injectors seems to be pumping out close to readings. No misfires. I did notice the High Pressure fuel rail sensor 1 , number are red when I’m looking at my Autel Scanner. Idle around 4800 , not sure what’s the number supposed to be. 2018 Duramax

What kind of fuel upgrades do you need to run this turbo reliably to its max?

It can be mod for have ballbearing?

is this tune compatible with a full delete? no more DEF EGR DPF etc thanks. any time frame for the 22.5 refresh????

Why not 19? Come on man

I’ve got a question and I hope you may be able to help with this I have a 2008 GMC Sierra 2500 deleted and tuned with 177k miles and my engine light turned on and it said to change the fuel filter so I did and then about 500 miles later the same issue happened and it reduces engine power, I have a code reader and the code is “P0087 Fuel Rail/System Pressure - Too Low Bank 1” if you have any advice please help!

do one one the 5.9

Most of the videos I watch says to test the injectors. Okay sure, but then what? Can they be rebuilt? Or are we just replacing them anyways? I'm familiar with gas injectors, where they can be cleaned and re-used. Not sure if diesel is the same.

2g and 3g 4life😁🤣

Don't waist your money

I have an lly with your built trans with the 6 speed conversion and built trans tuning I’m just shy of 600 with some fueling and air upgrades and no adjustment To tuning. I was told 530 I pushed that with a weak CP3 and boost leak lol.

You can watch the gas gauge go down with an 8.1 towing heavy in hill country lol

It’s an Isuzu engine put into a two time bankrupt government motors junk product

I'm not sure why is horsepower the focus. Most people aren't operating in the rpm range where peak horsepower is calculated. I really like both of these engines. LB7 for heavy, consistent, long distance towing. 8.1L for weekend towing lighter stuff and daily driver. For those looking into performance mods for 8.1L, 8.8L heads are worth consideration along with a turbo or 2 (gap those rings accordingly). These even came in some Avalanch models.

So how much more or less DEF fluid will my Ford 2022 use after this mod?

Whatcha got for a LML? 2016😊...

How about a 2016 Transit EcoBoost with the 6-speed?

You guys have a link.Where can I order this turbo

Is these for sale in California as well?

Nick and Calibrated Power playing chess while most of the field is playing checkers.

"Keeping the fan at an optimal speed" Uh... what? They have been electric for 20 years now... "Allison transmission..." you mean GM? "GM and Chevy are known for being smooth driving trucks..." dude they are literally known for being the WORST riding truck out of ALL of them!!! Your an engineer or what? Speechwriting for the Dems??? Cuz you dont have a CLUE

I'm confused with the statement, "Expensive to operate diesel" ??? I own both a 04 1500 gas Silverado and a 05 2500 Duramax. Yearly cost to operate are nearly the same????

So to be clear, You have drifted from the 3 speed on the column.

Dream truck

STR for LLY-LMM? I'm in that weird Build or Buy era. 06 LBZ (vin 2) 142K miles. fully stock. I want more sustained power and less heat under load when pulling grades in 100F heat going from 900 to 3500 ft. I also travel up to Flagstaff, and sometime Colorado. so basically, everywhere in US elevation wise. I would like to get to +100 wheel, but I'm more looking for drivability vs a "xxxhp truck". I know tuning is a HUGE part for these dinosaurs, but the truck gets pretty cranky running 2800+ to hold speed on these grades. it will do it and never actually overheats (230-241 at top). but it's clear oil temps are driving coolant temps when sustained at that RPM at WOT for 7-8 minutes. oil temps would be from the squirters saving the pistons from EGT. (I'm told). The stack was disassembled and cleaned, upgraded to Kodiak clutch that dropped 15 ECT. could throw a rad at it. but I think its EGT mainly from trying to hold peak HP on stock turbo, combined with high ambient. that's why I am thinking turbo. it SHOULD let me climb up a gear and drop RPM from the extra power. thoughts?

Spoiler: they could have made this video in a office and there wouldn't be anything missed.

How about the 2002, lb7?

2002 lb7, is that the same fuel pressure relief valve? Is it in the same location? Thank you

Where can I I buy a 4 inch turbo back mbrp straight pipe for Lly Duramax?

I have a 2003 Suburban 2500, 8.1 4wd, 373 rear, I have 155k on it would not sell it for any price.

8.1 mpg as well.

When is the mach 2 or maybe even bigger coming?

Fun fact. The MAS doesn't actually measure mass flow. It measures velocity and temperature. The engine computer calculates the volume flow from the cross sectional area of the air intake (where the MAS is located) and air velocity . It then calculates the mass flow from the volume flow rate and the air density via the air temperature. Strictly speaking it's not technically accurate, as it doesn't take into account relative humidity which affects air density to a substantial degree nor does it take into account height above sea level which also affects air density substantially.

Was this all done with the stock exhaust manifold?

Great job. We really appreciate the work that went into this. Invaluable data for these turbos. Thanks!
