S3 E42. We build an exhaust and fuel system for the Kubota diesel powered Honda insight. 

The hyper miler champ kubota diesel and Insight are a match made in shed gnome heaven.

This is hands down one of the best and super sincere car channels on RU-vid. Greetings from Slovenia 🇸🇮

*"Let's put all this Crap on the car"* 😂😂😂 Hope you had a good Thanksgiving Jimbo.

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. :)

The nostalgia of a 300 baud modem brings back memories. Kids of the early internet 🙂 Cheers Jimbo! 👍💪✌

The exhaust hose clamp is David Freiburger approved!

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!

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. -JJ

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!

One of the few channels that I look forward to every weekly upload. Hope the turkey was excellent!

Thanks Jimbo! Can't wait to see some supercharging tomfoolery in the near future!

"despite doing everything wrong or half assed". ... I just died laughing in my living room!

This is the best part of Sundays, hands down.

This tradition watching your vids is more fun than Thanksgiving 😅 🤣

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.

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.

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.

Am not a mechanic or fabricator but I really enjoy these videos. 😊

Hey Jimbo, you make it all look so easy, and my knuckles aren't even skint up!

Looks good, Jimbo. Can't wait for 15psi on the supercharger and the rack screwed all the way out!

Big respect for the heavy use of the word 'flange'

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.

One for the numbers. Keep up the great work. I look forward to every Sunday for more of your content.

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).

Always a joy, I hope Jimbo, family, and all the gnomes had a wonderful Thanksgiving.

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

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

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.

The metric measurements greatly appreciated 👍

Jimbo, I love that to you exhaust and fuel are the little things to make the car reliable and safe.

Fabricating things with the tools you have.........always a great skill to share. Mr. Average doesn't have a full fledged machine shop, so every bit of know-how helps.

To whoever edits. Somehow your whole video package makes a page peel transition look good, despite being hugely outdated :"D

Hey jimbo! Just want to say the best part of my Saturday is operating up RU-vid in the morning is seeing your video at the top of my feed and a nice morning coffee! Another great video keep it up!

yay! a parts collaboration with 100%Jake I'm happy his car (parts at least) are still on RU-vid

uncle rob(ot cantina) and his fun projects coming for thanksgiving dinner! I know what I'm getting him for christmas (hand wipes)

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.

I too have massaged things with a hammer, keep up the good work jimbo Im still open to adoption

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!

Love these builds.

Good stuff, thanks for sharing your videos. 👍

Just opening RU-vid on boring Sunday - Jimbo posted a video 2 minutes ago. Saved my day!

👍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.

BMW 12v in line pumps are about 45$ for an aftermarket brand one just in case you wanted something reliable and reasonably priced

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.

Thank you for the good job you do with the cars and with the videos. You make them informative and entertaining at the same time.

As always a great video. As to being able to fuel the car, we have both car diesel and truck diesel pumps here. The car pumps have the same size filler as the gas pumps so no funnel required.

Nice job Jimbo! I like that with each build, seeing the increased refinement, making the car more practical and less of a rolling lab experiment. Thanks for deciding to use the belly pan, so with all the body panels in place, I expect to see gas mileage to easily get into the 70+ mpg range with the car's light weight and 0.25 drag-coefficient.

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.

Essentially did the same thing to my diesel fuel tank, just left the stock head on for my fuel level sensor removed the original pick up tube and return installed a drawstraw and just a port to dump the return fuel in.

You can't please everyone all the time, don't even try Jimbo. Awesome video.

Your videos are always a great way to get the sunday going :)

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)

Glad to see the Insight moving along. I hope you packed your show shovels before the move. Thankfully, the snow doesn't last as long in Kansas so you may be able to take the Insight out in a week or two. Keep warm.

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.

Looking forward to seeing more of the Renault.

I told my buddy who just started as a heavy duty diesle mechanic about this thing and you could smell his brain shorting out

The wind tunnel was the death of car design

If the part you made works, don't worry about how you made it. Carry on

I felt like i was forgetting something, now i know what it was!

Thank you for the videos Mr Cantina, we appreciate the effort you put into them

The little I cut 50 plasma cutters work great for cutting plates like this made some beefeyier tappet adjustment tools.

ah my Sunday YT delight! Thank you sir!

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.

Awesome video Jimbo 👍

Frying a turkey and watching the video 📹 👌. Ready

Well, you're not This Old Tony but if it works, it works.

Seems fitting that I got a Honda ad that features the Insight for a few seconds 😂

I think Jimbo needs a few more machine tools .... plasma cutter etc great fun to watch nevertheless 👍

The dial up tone is bittersweet, keep it going! It confuses the younger generation!

Happy Thanksgiving friend. 👍

Awesome thanks Jim your videos are great.

Greasy hands make the food taste even better 😂

Good Episode! Thank you Jimbo. 😁

to prevent diesel leaks, use permatex. If still leaks, combine it with a few turns of thread. That's the only way we solve diesel leaks on threaded joints where I work.

Good job brother also I love your music on the video

Somehow making this flange on a lathe didn't looked easier at all. 😊 Jimbo really likes playing with the lathe 😊

For the flange, SuperFastMatt is a big fan of Send-Cut-Send service. Might be worth a look for other flanges.

Great progress! You are deserving a good meal!

Thanks for the heads up and the R3 y R4 y R5 wireless Bluetooth y contento con el esquedulo. Here's my comment for the algorithm

Happy Thanksgiving’s Jimbo ! Nother great episode

We all hope you had a great Thanksgiving!

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.

Happy Turkey day ! Thanks for the vids

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)

Man, I'm late today. Coffee and Cantina time for some fun content!

Interesting as heck as usual. Want to see how this comes all together, keep up the good work!

Short and sweet video!

To get rid of that diesel smell from your hands try zep cherry bomb soap worked great for me.

I think you should space the hood up a bit, so air coming through the grill can leave out the top, instead of under the floor.

Weld a plate on the bottom of the drop lines, for empact

happy holidays crazy car guy !

What! I love the smell of diesel!

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? 😕

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.

Great video as usual. Great wrk guys

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.

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

An oxy torch works really well for cutting 1/4" steel plate
