The hyper miler champ kubota diesel and Insight are a match made in shed gnome heaven.
Running it on vegetable or used oil makes it an apocalypse vehicle 😅😅
@@carholic-sz3qvThat’s what I’m saying! Would love to see that, should help with the exhaust smell too!
Think he'll break the 80 mpg mark with it?
@@randr10not with the supercharger, but when he goes back to a turbo, yes.
@@carholic-sz3qv they are doing it well
some even got as far as plane fuel ( in china using ex curry oil leftovers)
This is hands down one of the best and super sincere car channels on RUclips. Greetings from Slovenia 🇸🇮
*"Let's put all this Crap on the car"* 😂😂😂 Hope you had a good Thanksgiving Jimbo.
The exhaust hose clamp is David Freiburger approved!
It's a cold rainy morning here I'm sitting in the garage watching the rain and drinking some coffee. Perfect robot cantina environment. Loving this build Jimbo I can't wait to see it on the road!
Running your lathe in reverse and with a tool held upside down is fine ONLY as long as your chuck is not a thread on chuck. Otherwise you run the risk of having the chuck move off the mounting face or worse, coming off putting a hole in your shop wall.
:)
I've gotta say Jimbo, I love your channel, but that exhaust flange was extra as hell hahaha. Hole saw to size, cut off wheel to make it square, round the corners with a belt sander if necessary. All that said, obviously your way was cooler.
Happy belated Thanksgiving Jimbo! I hope you packed your gut with turkey and all the great trimmings and you enjoyed time with family. I also wanted to let you know how thankful I am for your weekly videos, they always give me something to look forward to, I know that makes me sound lame, but I’m not able to work since a stroke caused by an AVM when I was in my early 20s and the emergency brain surgery to remove the AVM caused damage to that section of my brain and the scar tissue caused pretty severe seizures, but thank God I was able to undergo brain mapping and resection in early 2019 to get the seizures under control and thankfully after a few complications caused by clotting and 3 brain surgeries in less than 7 days, my life has been drastically changed for the better. I can now live alone without a constant fear of death from an out of control seizure. That’s a long story to say I have so much to be thankful for, but most of all, I’m thankful God saved my life and my soul. Again thank you Jimbo for your weekly videos. Once a week videos are great, anymore and it would work you to death and the videos maybe wouldn’t be as special to us who eagerly await the Sunday uploads. Stay safe buddy and God bless.

Starting out Sunday Funday with my favorite series, keep up the good work!
So excited to see this project coming along! We'll have to see how your turbo diesel Insight compares to my Lithium Hopped-up Hybrid in the spring!
Hope you all at Team RC had a great Thanksgiving, thank you all for making this great content! Can’t wait to see the Supercharged Diesel Insight roasting those front wheels!
I seriously doubt that even with all the stupidcharging in the world that 722cc Kubota isn't going to be "roasting" any front wheels. Unless the car catches on fire, that is. Jk, jk!😀
Fyi: the narrator mentioned a turbo was going to be used, not a supercharger :)
I really think with the power and mileage of that kubota, and with the lightweight aerodynamic body of that Insight, this is going to be the closest you've come to building a useable "car". I can't wait to see the speed tests. You could even take the time to 3D print a screw in adaptor for the filler neck with a finger to open the tamper flap.
I seen an episode of Motor Trends engine masters where they crimped header tubes with a hammer and dyno tested them after each time they hammered dents into the headers. It took an amazing amount of hammering on the header tubes to affect the horsepower output so you little dent in your downpipe should not matter at all.
The nostalgia of a 300 baud modem brings back memories. Kids of the early internet 🙂
Cheers Jimbo! 👍💪✌
Thanks Jimbo! Can't wait to see some supercharging tomfoolery in the near future!
The metric measurements greatly appreciated 👍
'real measurements' *poke poke* 😆😆
HAHAHAHAHAHAHAHAAA!!!
Quarter inch steel may as well be CARDBOARD!!!
[but then I am a 45 year experienced machinist, as almost making 60 years of age as a Wabbut]
Meh...
DIESEL IS AWESOME!!!
I CAN BREATHE IT EVERY SINGE DAY!!!
[already kinda do]
diesel powered Honda , and you DON'T like the SMELL . No problem , just use vegetable OIL ,OLD OR NEW . Smells good now
You need a plasma cutter, my friend. That was possibly the second most laborious method of making an exhaust flange that I've seen. No offense, you got there in the end, but a plasma cutter could have knocked that out in under a minute. You can design the 3D printed template as a guide for the cutter, I've done this and it works. I'd recommend the Bestarc BTC500, it's only about $250 and will make your life a lot easier.
I hope it is a Paxton Supercharger or similar. I know, most people don't like them. Meh, I don't care.😆😆😆
Love all your videos, they're part of my Sunday morning ritual. But am I loosing my mind? Didn't the exhaust flange fabrication go from round to square? 😕
Am not a mechanic or fabricator but I really enjoy these videos. 😊
BMW 12v in line pumps are about 45$ for an aftermarket brand one just in case you wanted something reliable and reasonably priced
uncle rob(ot cantina) and his fun projects coming for thanksgiving dinner! I know what I'm getting him for christmas (hand wipes)
For the electric fuel pump. To make it stop leaking, it is to wire up a 100 ohm variable resistor/rheostat. By doing so, you control the amount of flow by reducing pump power. I install an electric lift pump by factory update on a 08 Duramax to solve the vacuum lift pump on the high pressure pump (Low fuel rail pressure code). It leaked fuel at the weakest part of the fuel line which is in front of the charge air cooler intake to the crossover valley. Had to reduce the psi or it keeps leaking.
"despite doing everything wrong or half assed". ... I just died laughing in my living room!
@RobotCantina, you seem to be like me. Always wishing you had money and room for better tool options for fabrication.
I agree, they are just an odd looking car. A straight on view of just the front end isn’t that bad, but everything from the front fenders on back is just a head scratcher. Did the engineers all celebrate close one eye and freebase cocaine fridays when they designed that thing or what?
i am thankful for you, jimbo, aaaaand your very understanding and tolerant friends and family! diesel perfume at turkey day, ha! thanks again for the best vids on the innurtube
10:24 I used a simple fuel sending unit on my rat rod. It jumps all over the place. I did not put baffles in my tank. I guess we will have to see if you have the same problems.
Did ya' have a Merry Thanksgivin', Jimbo? Hope so. PS, love the progress on this project thus far. Can't wait to see what ya' do with it after it's built 'n' good to go.
Hey, I am fairly certain that there is no 3d printer filament that is adequately resistant to any fuels to be used in a gas tank. I expect it to fail completely and quickly and maybe even messy
Would skip the supercharger, outdated technology, turbo is always going to be better
Looks good, Jimbo.
Can't wait for 15psi on the supercharger and the rack screwed all the way out!
The wind tunnel was the death of car design
You could have just used the angle grinder to cut out the flange directly after marking the holes and the edges for a lot less work.
To get rid of that diesel smell from your hands try zep cherry bomb soap worked great for me.
I'd rather laugh at you than scream at you [HOP HOP HOP!] 🐰🐇
I too have massaged things with a hammer, keep up the good work jimbo Im still open to adoption
To whoever edits. Somehow your whole video package makes a page peel transition look good, despite being hugely outdated :"D
Well, you're not This Old Tony but if it works, it works.
what do you mean it's ugly? how else is a tennis shoe supposed to look? pfft
Happy belated Turkey Molesting Day :D
Good stuff, thanks for sharing your videos. 👍
Upsidedown and backward. Not as silly as it sounds
Heads up, I had a problem with my OM617 diesel swapped Dalota. My fuel return and pickup line were too close to each other in the tank. This allowed the pickup to collect some air. It wasn't a problem for short trips. But, after a 20 miles stretch at 65mph, my truck would surge and act like it was running out of fuel when idling at the redlight. I had the tank and fuel system in and out mutiple times chasing this gremlin. The fix was adding a 12" piece of hose to the fuel return so it ended up away from the suction.
Thanks!.... Its the little stuff like this that will drive a person crazy. I'll make some changes soon.
@@robotcantina8957 I'm not exactly sure why there were bubbles coming from the return. It was a 340k mile 1979 engine though.
@@robotcantina8957 I'd really like to recommend a car lift. It really made life so much easier. I got a new 9k capacity lift delivered for $1600 about 6 years ago. It took some shopping to find that deal. After a few uses, I wish I had bought the lift before ever buying a car.
We all hope you had a great Thanksgiving!
One for the numbers. Keep up the great work. I look forward to every Sunday for more of your content.
Weld a plate on the bottom of the drop lines, for empact
Need a turbo on that exhaust manifold!
That's what I'm sayin!!! Where's the turbo Jimbo?!?!? BUTTTT I can't wait to see the supercharged version first, maybe it will be better on such a small displacement diesel engine.
Happy Thanksgiving jimbo. Also im on way way to 5k subs ❤
gasoline pump works fine in diesel fuel, fwiw. But you really don't need/want it, so it's all good that you deleted it. :)
You can cut the little funnel thingy out of the filler neck so the diesel nozzle fits in it.
The mechanical fuel pump should work fine, but if you do end up with issues, you could always replace it with a 'clicker' type electric fuel pump, they're really cheap (like, $5 cheap), and both reliable and super common (so if it does break, it's very easy to get a replacement at any auto parts store or online)
The local filling station uses the ultra large diesel nozzles on their pumps, These outdated nozzles make it impossible to directly fill the tank even if we gut the filler neck.
I've recently watched a video on superchargers and I doubt you'll be able to find a roots type that is efficient for small engines as they don't really like to make them for small engines. Basically when you're running a blower too big and slow there is a lot of air leaking or something. Greg's Airplanes and Automobiles made a video on this.
There's probably a centrifugal supercharger like a Procharger for your engine size, but I haven't looked that up.
The AMR 500 supercharger we plan on using was designed to be used on 660cc engines.
Always a joy, I hope Jimbo, family, and all the gnomes had a wonderful Thanksgiving.
Superchargers take power to make power. They work but you pay in increased fuel consumption. Turbos _can_ be a free ride: power when you want it, economy the rest of the time. Not invariably, of course. Consider a remote turbo installation. Hang the turbo completely out of the engine bay, park it somewhere in the tail. It adds a tiny bit of lag but not enough so you'd really notice - especially not when you're driving a diesel Insight. Too much other stuff is weird already; turbo in the spare tire compartment is just one more freckle on this particular spotted cow.
Fun thing about a remote turbo, the big delivery pipe running back up to the engine bay is sufficient intercooling for most applications.
We tried the turbo on this engine when it was in the Saturn and it worked good , but not great. You see, we used the smallest turbo that was available and it was still too big. The supercharger experiment is exactly that, its an experiment to see how it will work on the little diesel. Experiments like this may not make sense, but most of the audience wants to see unusual experiments.
That mechanical fuel pump. If they fail that often it is most likely due to the fuel pump being to close to the Cam that pushes the leaver.
You might need to space the mechanical fuel pump out to reduce the pumps stroke to not damage the diafram in the pump.
Britanic restorations did a great video on this when he had a large amound of pump failures on his 300tdi land rover engines.
thanks! that makes sense and perhaps I'll start off with two gaskets behind the pump.
I felt like i was forgetting something, now i know what it was!
If we all used this setup pretty sure we'll get fuel once a year.
You can't please everyone all the time, don't even try Jimbo. Awesome video.
I told my buddy who just started as a heavy duty diesle mechanic about this thing and you could smell his brain shorting out
LOL
You're not alone it does look weird.
You get a new microphone? Sounds crisp and great bass response to your voice.
Same microphone... Hmmm
optionally, after metal is center punched use angle grinder to cut a square and hole saw bit for the center (ACE hardware sells the bit for $18)
Just enjoy the video, Jim’s got it figured out.
happy holidays crazy car guy !
If I ever get any money, I'm going to buy this guy a lift or 2.
I would love to send him about 100 yard gnomes so they could make it back to the videos again
I haven’t read any of the comments, but just so you know for future projects those gasoline engine fuel pumps work perfectly fine for Diesel, at least in the Audi and Volkswagen World they are actually the same part numbers for certain models, gas or diesel, and I have done many diesel conversions to other manufactures and had zero issues using the original fuel pump. now second a cheap $12 fuel pressure regulator from Amazon or eBay works perfect to lower the pressure down to about seven psi for the diesel to run, but you do need a return to the tank. But almost any diesel needs a return back to the tank anyway.
Gasoline pumps may work for diesel but I do not believe the opposite is true. Diesel-only pumps (and other components) may rely on the lubricity of the fuel for proper continued operation.
From my experience, OEM electric lift pumps for diesels seem to survive fine with gasoline. But aftermarket ones “mostly” cannot tolerate gasoline if they were made for diesel. And of course, mechanical diesel fuel injection pumps won’t survive very long when used with gasoline because they rely on the viscosity of diesel fuel to function properly.
Love these builds.
For the flange, SuperFastMatt is a big fan of Send-Cut-Send service. Might be worth a look for other flanges.
Awesome video Jimbo 👍
Turbos are cool and so are super chargers. But do you know what's even cooler? TWINCHARGING.
Most excellent progress, Jimbo. Will we get a "Foodie" review of Thanksgiving dinner next week?
Don't fret on that pump. I had one fail, but the second one has hundreds of hours on it and is still working.
No turbo or stupid charger?
Make a twin charger like you did on the predator engine if I remember correctly. No throttle plate and collapsing tubes to thing about here 😃
Looking forward to see both the AMR300 and a turbo on this beast in the future 😉
As any right minded machinist would....make do with what you have at hand.
Cap'N Crunch score 10/10.Now where's my Cheetos?
Looking forward to seeing more of the Renault.
The weather here has been clod, rainy and snowy. we will get back to the Renault when the get a good patch of weather.
Put the turbo back!
There wasn't anything about your machining job that was half-assed, Jimbo! That was a whole-assed job if I've ever seen one! You have to stop selling yourself short, and take credit where it's due.
Any gasoline pump should work with diesel fine. Yes, diesel is slightly more viscous (thicker) but unless you're in the arctic it shouldn't be a problem.
The inverse is where problems come in. Many diesel pumps rely on the lubrication factor of diesel, and burn up when they pump gasoline. Best case scenario you lose a pump, but since gasoline is so much more flammable than diesel, it is a serious risk.
Anyway you should be fine with the OEM fuel pump.
Ja know It just occurred to me. You said new bushings wernt in the budget for the Renault. Have you ever thought about 3D printing them with tpu? I imagine it would be segnificantly cheaper.
100 Percent Jake, Watch JR Go, Hoovie's Garage and the Car Wizard are all in KS. Have you ever met up with them?
We called them the armadillo. So yeah, they do look goofy...
If the down pipe does not have any preload when hose clamped to the mount, it should be fine.
My Buell XB12's complete exhaust system was hard mounted to the engine, as in not connected to the frame, and never cracked.
I'm not upset, offended or anything like that, everyone has a different stroke. However I love that lil nugget, and wish I could afford one...
Happy thanksgiving! Consider an electric supercharger, turned on for acceleration only?
How I make flanges like that: Cut rectangle, cut big hole with hole saw, drill small holes, weld pipe. 10 times faster than your method.
Just a heads up my kubota diesel G1800 lawn mower uses a kubota version of the green pump you have and its a rock solid unit despite being 20yo.
First-gen Insight is my dream car and I was lucky to get one in great shape with relatively low miles.
It doesn't upset me that you think it looks weird; it does look weird, compared to lots of other cars. But that's mainly because most other car designs don't care nearly enough about efficiency, while they pulled out almost all the stops pursuing efficiency with this car.
It's form following function, and I'll take that every time even if it means the car stands out (despite the fact I don't like standing out).
Twin charge it!! Use both super charger and turbo. Make a valve that pipes the turbo into the supercharger when the boost is higher than the intake pressure. Using a leaking valve so it can build some pressure, the diverter can just shut off the inlet to the supercharger. So all air comes from the turbo. After it's spooled up. Maybe use a bypass to put the supercharger out of the system, diverter it's outlet to it's inlet. And the turbo pressure can be used to operate the valve. Give it 8-10psi from idle till the turbo spools up! Awesome, and happy thanks given
Happy Thanksgiving’s Jimbo ! Nother great episode
yay! a parts collaboration with 100%Jake I'm happy his car (parts at least) are still on RUclips
Yes, some heads exploded. But th most successful machinist are those who work with what they have. And not worry about what they don't have.
Have you considered rebuilding the original fuel pump assy, replacing the hi pressure pump with an in tank diesel lift pump?
I can't wait to see this one on the road!
Some Hot rod diesel guys when they go to big external pumps. Will use the factory fuel pump bucket and just make a siphon tube in place of the electric pump.
down the road you should do a sequential setup with the blower and turbo. the blower could use an A/C clutch to disengage when the turbo takes over. maybe a computer controlled bypass valve.
Wonder how well a 1105 turbo kubota would fit. Too bad the 1.6 vw was too wide. Probably would of fit the saturn.
Cool i wish i have such superior skills/capability to craft awesome stuff and things
Honestly I like watching these projects unfold better than the guys running 6 second quarter miles with their cars these days. It makes it boring to watch when they just go out and buy a $100k billet engine and slap it in there then go run some passes. It was way more interesting when they were in their own home shops slapping turbos on junkyard motors.
I do machine work, I see nothing wrong with your lathe setup.
So long as the cutting edge matches direction of spin and it's all firmly mounted, go nuts!
The little I cut 50 plasma cutters work great for cutting plates like this made some beefeyier tappet adjustment tools.
People getting mad at you for saying you think *you're* car looks weird. I love the Internet.
👍for wanting to use a factory Kubota lift pump. The one on Bota tractor is 25 years old and has never given me any trouble.
