Pwoahhhhhh Cant wait to get big baz on the tracks next to Kevin the K truck what a beast!
Just a name suggestion but does look a bit like a Kev 🤣
4@@Unclepooly
Let’s the builds begin @Unclepooly 😉 I smell a drag race with big baz with lots of cheesy fast and the furious liners lol
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. 🤙
@Ahhhhhhh1983 you been sniffing diff oil again mate? I didn't see any wonky stuff.😂😂😂
Thanks for the shoutout guys! We hope you love the system.
No worries! Pretty excited to put it through its paces!
@@macpreston 🙌🙌
It’s great seeing someone who is so good at what they do, Nick seems to know everything - really impressive
That got super complicated, real quick but totally captivating. Those Kaisen Lads are wizards. What a great episode Mac!
bringing in the whole crew for this one, nice.
Haha got a bit on ! Need some experts 😂
Definitely above my pay grade this one!
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❤
Thanks Jesse ! Haha happy Valentines my dude 😜
Hell yeah !! Bring on a lot more Mac
Best build ever
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
Haha that’ll be the best part thanks heaps for all the help boys! Couldn’t have done without has!
Keen to see the Prado do a jump 😜
@@macpreston anytime! Been a pleasure
Hell yeah fellas!! So good to see all the boys come together on this project!! Bring on the coil-over goodness, can’t wait. Love your work lads 🤙🏻
Thanks Geoff 😎
Has to be a future merch with the Cummins motor and twin war whistles on it. With the saying just let it eat 😂
Loved it! There's a good crew of guys on-board on this project🤘
Agreed definitely some knowledge getting thrown around its great!
It's great to see young guys really passionate about their skills with old school stuff
Keep it up team
Loving the forward planning and future proofing with parts choices.
Oh yeah looking goood!
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.
Absolutely pumped for this build!
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 😂
Yeww! Epic video. Boys are doing wonders
Well done simmo and the kaizen boys
So good. Loving the build, love the long episodes, can’t wait for the next one.
Thanks ! 🙌
Mad video guys, Patience pays divid ends
Man, the boys know their stuff. Very impressive
Macca you’re a bloody wizard
I’m level 10 outta 100 wizard nick is level 99 😂
Looking awesome, really coming together that is going to be one beast of a tourer if that’s you plan
Sickk onee! Love this!
What an episode Lads ... Top work 😍
Finallyyyyy been waiting on youtube home page for ur next episode
Nailed it ! 🤩
Cant wait to see the finished product. Leave it up to Mac to bring us some insane builds haha.
🤩
Haven’t been waiting for this at all 🤠
Absolutely loving this build!!! Love ya work boys 🤙❤️
Thanks so much!
Bloody loving the content boys and Love that pooly joined RUclips as well.
Oath he’s killin it to so stoked!
Solid effort lads 👌 mint ep
That poor 8 speed😂 loving this build fellas. Keep up the epic content
This is so sick can’t wait to see it on the road!!
Same !
This is awesome mate!!
You guys are sick! Building cool shit and being able to watch this as Australia content makes me a happy boy!
Thanks so much 🙌
Gday, these episodes never fail to impress, going to be interesting to see how that transmission holds up, cheers
I know right 😅 we shall see
Frothin these episodes! 🤘
Amazing vid lads! Can't wait to see it flexed up on a forklift or sooting up the flex track ❤
Gonna be wild !
Twin turbo for the win 🤘🤘🤘
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
Sounds like a wicked project! @@andrewk7731
Haha ill do my best for you than!
never thought i’d see a nz plug, too much brother mac🤟🏽
Gotta support the brothers over the ditch 💪🏼
Best episode boys 😍😍
This is insane! Loving the progress ur getting stuck in
Thanks !
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.
Great info to hear thanks mate! And every bit counts mate welcome to the channel! Do you run twin pumps or just a single 14mm?
@@macpreston single 10mm pump with 150% over injectors. Airdog 150 lift pump.
This build is mental, well done as usual boys
Thanks mate !
DONT RUSH, you have great mates 👍🏼
Oh baby that sounds beautiful
Time for a zinger box , great work boys can't wait for the next one to drop
Thanks Joel !
In the UK our 18T box truck has that engine, running well past 1million k's. Seeing you guys strap compound turbos to it is hilarious :)
😂
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
Thanks so much !
Haha agreed a sand blaster would be amazing!
What adapter did you use to mate the 8hp to the 6.7? Couldn’t find any of the shelf
Well done guys 😎
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 RUclips, 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!
Thats wicked to see! Im all about it! Especially when we own the mistakes rather than leading people astray! Keap up the good work!
Can't wait for episode 6, 6 turbos
Haha 🤣🤣 he is onto us
Okay, now this was educational. That young lad helping you need to be on more often.
Agreed hes a wizard!
Keep them kaizen fab boys around. That was sick.
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.
Yep well, the guy building seems to have some faith so we are all interested! Watch this space !
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.
Pwwoar TJ and MAC this is perfecto!!
🙌
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.
😂 I know right , we r gonna need more turbos 😆😆
So far past my knowledge level - but I loved it - great video!
Thanks mate !
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 🤙🏻
True ! Thanks for the tip
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
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 😂
😂 yeah it’s great to have access to such good stuff !
Haha to busy drinking and fishing up there 😂I did alot of work up there great place!
Love the show mate
Thanks Russel !
Great Ep!
Thanks 🙌
Yep that's fully sick.
Them young lads cracking me up the entire episode
Boys are quick witted haha
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
Thanks mate! I may end up biting the bullet and going something expensive but for the moment well test out the patrol case!
this thing is gonna be insane
What an awesome episode,
I didnt even know you vould compound them? Makes sense to do this now.
Thanks ! Yeah pretty wild 😝
Yep! Its mega common in the states in the rams!
Killa episode
Good job boys !
Thanks mate !
That was decent lads. Well done!
Thank you !
Wow never thought that would be running any time soon
Onto suspension now!
Does anyone know what's best master cylinder and slavesetup for an nv4500 in a 79 Chevy c20 with rattrap clutch at present
12 valve Cummins swap
Who made the adaptor for the gearbox at the bellhousing I didn't know anyone made them
You found a very smart, young mechanic there.
That's fckn awesome, can't wait to see it party offroad
Gonna be wild 😅
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
Moneys on 3 months haha and cheers mate I’ll keap pluggin without rushing!
U should do a tub exit exhaust Macca
I agree!
@@macpreston black smoke just pouring out the side of it 🤤🤤🤤
Watching this over Valentine’s Day dinner with the Mrs 😂
Good work fellas!
Haha he knows the way to a lady’s heart 😂
Thanks for throwing so much money at this can't wait to see it on a track or towtruck 😆
Haha thanks mate good that someone apreciates the massive hole in my wallet building this thing lol!
8speed is going to munch that torque, don’t worry chief🫡
Cheers mate at least there’s one person with some faith besides me 😂
Cool love it
👀👀Definitely need more intercooler👍👍. Thousand horsepower totally doable as long as you keep the power higher in RPM
This kind of wizardry would put a horn on a jelly fish, ripper job boys
Who did you use to import the engine?
call it big Frank the hole thing is a Frankenstein looks like an absolute unit
Tj and Mac toooo theee mooon once this thing hits boost
Not sure I wanna be in it when Macca is driving 😂
Hahaha your not wrong 🤣
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 ❤
Go home ya parmi natzi hahaha Keen as to get all the old rigs together!
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
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
haha fingers crossed!
I’ve got faith in the 8spd, I reckon it’ll do pretty well
well done looking good
Thanks !
Mad.....I like the longer episode, it's like a 2 for 1 deal
Thanks !
I’ve been wanting to do this with an LML duramax….
Looking Great there boys! Hopefully thats a Dana 60 up front !
Sure is and 14 bolt rear!
Lets look for an Alison 😂
😅
Nice lads. Will the body be satin clear coated to keep the patenia
That's the same axle truss and diff cover that I'm running on my 74 k5 blazer rock crawler.
Mint!!
