Really enjoying this build. Not sure if you guys watch your vids after you post them. It you have some wonky stuff going on with your focus on the cameras. Makes it really hard to watch and couldn’t finish the video. Hope this helps for the future. 🤙
How bloody amazing is that thing that scans your chassis!!! That’s a great job to have that thing running. Definitely wasn’t boring!!! Loved every minute of it. Happy Valentine’s Day you bloody legend’s❤
Hell yeah! Been awesome working with you lads on the project so far 👌🏻, keen to see this baby on the dyno and then out on the road disappointing some High HP Petrols
American here! I use to run these 6.7 Cummins trucks for work. I asked my buddy who is the mechanic if you can run the 6.7 at a thousand horsepower with stock rods, he said “for a little bit”. Sounds good to me 😂
I saw a Garage 76 T-Shirt. They're now in Queanbeyan and banned me from further work and servicing, simply, because I complained about bad services - replaced an air filter when not necessary, replaced cabin filters when not necessary, post-OEM upper control arms not greased, screwed up a tyre rotation with TPMS fitted, left the drivers window down on pickup in a main street and the tug unlocked. Didn't empty and clean the catch can, nor drain the secondary fuel filter as requested. Despite being a 'Master Tuner', I got a vanilla downloaded tune despite my towing requirements. I had to pay another dealer for a custom tune - $1200 as Garage 76 wouldn't rectify their obvious error. There you go, lesson learnt, shop around.
Man, when I was in High School, I wanted to Diesel Swap a C20 so bad. Living vicariously through you man. Cheers from America mate. Following this build.
Gday buddy I'm in Australia I'm getting a lil old but got a 12 valve p pump manual in my shed here in New South wales that's begging to get in the 86 square body that's sitting outside Mine won't b as elaborate but still b nice engine and box out of 96 2nd gen 2wd ram it's not the 700 hp I want it's that nice big block torque At low rpm I may head for an Allison 6speed when I get sick of shifting and clutches Still promises to be fun light And not 2 complicated Cheers
The bottom end will generally stay alive if you keep the torque under 1800-1900 lbs. Depending on how tight (quickly the turbos spool) it might be hard to keep the truck from making that torque low in the RPM range. Example, If that engine makes peak torque at 2,200 RPM, the rods would be in trouble. The turbo sizing will really dictate when the truck will make peak power more so than the fuel. You can manipulate the fuel tables a bit to try and make power later in the RPM's but it might be out of the efficiency range of the compounds, thus making it possibly very smokey, laggy, and or runs hot. The lift pump @ 290gph is more than enough flow to make 1000hp. The injector sizing and fuel pump will be your limiting factor. A single turbo will make 1000hp and a lower torque number to keep the engine alive but you will miss out on drive ability. 1000hp is cool, but 6500-750hp engine you don't worry about is way more fun to drive and have mess around with. More useable too. Plus with how light that truck will be, 650-750hp will still feel like more than enough power. In summary, keep the compounds and go for a lower HP rating.
So many people have bent/broke con rods on 6.7s after doing compounds and injectors that, even with a custom tune that reduces torque at low RPMs, he's rolling the dice. A compound S363/S480 with mild injectors and a 10mm is 750whp all day with plenty of low-RPM power to turn a burnout into a windowed block. It might survive at high RPM but when it upshifts and sucks the RPMs down to 1200 while the turbos are pushing 60+ psi... say goodbye. He should stay with stock injectors/CP3 and swap out the s480 for a S475 (~600whp) _or_ put in a set of Wagler street fighters and never worry about it again.
NV271 should be available as a bolt on for your transmission and is designed for a GVWR of 17,500lbs. 2:72 low range and used in sled pulling in the states. I believe they are all left hand drop but you need a bigger front axle anyway. There is also a kit to convert to a divorced case if it comes out of an f-truck which can help with packaging. The 273 is the same case but in electric shift
The tech used in this build is next level. Soo awesome, wish we could have done this back in the day. I mean its probably still not available in Darwin NT we are still years away 😂
I make right around 1000 hp with a big single turbo on a stock bottom end 5.9l. It's been reliable so far. I know quiet a few guys that have been making 1000 hp with stock bottom end 6.7l's as well. The general rule is to keep the torque numbers lower at lower rpm. The high torque numbers at low rpm are what kills the rods. So needless to say, tuning is a huge part of it. How heavy your foot will be is also a big part. Great video, just found the channel today. Hope this helps a little.
Ahhhhhh Mac, 38 minutes 35 seconds in, I have to say I'm the exception to the rule here, as having a fun hobby offroad channel on RU-vid, I don't edit out the mistakes. I want everyone to take away something from my channel, from how cringey I was offroad at the start. to learning where i miscalculate and stuff up on the bigger tracks. But anyway, loving the video and build, and frothing for more buddy!
I was also looking at the 8 speed for my 800hp compound 12 valve cummins swap (I have an 8 speed behind a LS and love it) but when I did the numbers, the math don't math. Even the best of the best built 8 speed box from a well known 8 speed builder in the states wasn't sure if it would hold up to compound 5.9 cummins torque numbers. 6.7 can make more torque than the 5.9. I have gone the well known and tested direction, 47re with goodies. The 8 speed might be good for 1000hp but it wont like the 2200-2500 lbft torque.
You really should build a 6mm stainless guard to fit between that 8hp and the truck body, saw some videos of gear boxes exploding and I can tell you that if they make BIG holes on the floor, imagine what they can do to you… stay on the safe side!! Awesome build mate 🤙🏻
Haha yes i did see that, but i also saw what they were trying to do! Safe to say i wont be holding a hydro handbrake on and redline shifting gears that whole situation made no sence haha
Love ya work lads. The Kaizenfab boys know their stuff. Did have a heart attack when you were wire wheeling the chassis though. You need to get a fair dinkum awesome sandblaster dude to come up and do the chassis for you 🤔🤔😜 Can’t wait for the next installment
This is an awesome build guys! But don't let this distract you from the fact that Hector is going to be running 3 Honda Civics with spoon engines. And on top of that he just came into Harry's and he ordered 3 T66 turbos, with NOS, and a Motec system exhaust.
yes boys, Dream build running any cummins with compounds. This will be a 10 second 1/4 mile truck surley. Match with a 8 speed ZF box. What a gangster combo boys
this is always a bit hard to explain but when you have an offset t-case output and a centred diff there isn't two angles there, as in there's not an up and down angle plus a side to side angle as far as the driveshaft is concerned it's just one angle. picture the car being tilted until the driveshaft angle is up and down like a "normal" one. but moot point anyway the cruiser t-case won't be strong enough and neither will the nissan one. as i said on the last video you run an np205 so you aren't blowing up transfer cases.
Ya should talk to al at the skid factory bout the rod question And if he don't know rich from deboss garage will know exactly Also ask al bout fire ringing / oringing for holding the head down tight
I think youd want the 1.32 housing on the 480, I've got a very similar setup on a mechanical 12 valve. But with the 1.15 rear, drive pressure will be mad on your 6.7
Hahaha nah XXXX sucks. Love this episode guys, these guys know their stuff and really enjoyed watching it all. Can’t wait to see that 8 speed get annihilated 😂🎉 Big project, huge amount of work, keep killing it! Let me know when you want some pretty pictures ❤
nice work. Nice amount of redundancy built into the truck too, with easy to find parts. As much as it pains me to say it, don't rush into this episode. 8 speed will last 3 months from the first dyno session cheers Jim
