- In this video I build a custom intake manifold to run a throttle body and 1 injector per cylinder on this Johnson/Evinrude 250 V8 in preparation for it to go into my 510 Datsun Wagon.

I’m a marine mechanic. I have lost count of the many hours that I’ve thought about doing this exact project. Awesome.
How would he handle the water that gets thrown outt with the exhaust?
Ya problem is two strokes are extremely particular when it comes to fuel air mixtures, should have kept the individual throttle bodies, these motors have millions of dollars in R&D just to make them run right.
Same here,but then i have a passion for two stroke
What about a cooling system? and timing advance....
The young man is good keep up the good work
I love this channel, he may not do everything right or how other people think it should be but my guy is out here building crazy cars, building dreams, and creating content. Love it or hate it, it’s amazing to see.
He makes great content. Agreed 💯!! And you can usually bet your life the “CZcams comment section experts” that tell him how THEY would’ve done it… 100% have never done it. Lol. Either put your phone down and actually build something, or sit down, stfu and enjoy what he’s doing for us to enjoy!
@@brandonbman5921You are 100% right mate.
@@brandonbman5921yep id agree with what your saying after working on and building for myself and other people over 40 years ive found many paths to achive the same ending.so when i brcame the boss id keep my mouth shut until someone ran into a problem then i would grntly nudge them in the right direction.and i ended up with a good crew who would bust their asses for the shop
Yep putting it all out there man! His determination and persistence will lead to success
Log manifolds will give it that 1930s look but you had a perfectly good intake and throttle bodies with the the stock carburetors and airbox. You don't have to use them for fuel, just adapt a throttle position sensor or perhaps a ninth . You can add injector bosses to the "front half" to inject directly into the crankcase. Just drill and epoxy after you disassemble. This is better than before the reeds.
Exactly, he can try to run a supercharger through the manifolds later, but just stick with the reeds until it's running in the car.
Problem there...unless he gets a marine 2 stroke engine ECM an automotive ECM only wants to spray every other piston drop. I worked in a marine repair shop, the worst part of the business is ECMs. Horrible expensive, even ones for 4 stroke motors in I/O boats.
@@davidleskov5078 Im sure there has to be a solution out there and its probably related to the guys messing around with rotary engines as they have a similar issue in regards to not having a traditional 4 stroke cycle.
@@davidleskov5078 I just had another idea, since he probably isnt going to use the ECU for ignition timing you could just spoof the ECU into thinking you are running at double the RPM so its firing the injectors twice as often, another problem might be that you'd need a high quality injector that could open and close fast enough for a two stroke, since at 6000rpm the injector firing rate would be like 12000rpm on a four stroke engine.
@@baconpop4388 yes, put a second Hall sensor on the crank at 180* so the engine appears to be spinning at 2x, doubling your injection impulses.
Man, that manifold is crude, but considering working with less than ideal equipment, you are chewing your way through damn well. Great job and hats down.
Maybe instead of buying 25 project cars invest in the right tools to work on them?
Each time I flipped a project I bought something I needed.
Can you do more of a walk around vid of the engine, keen to see where a gearbox would mount up. This could be one of the coolest projects on youtube currently, great work
Hardest part of the job is having the right tool
I like how you have been going along, it really gripped my attention to see how you would cobble up an intake manifold for this engine, mainly because I have often thought about converting a 2 stroke outboard for a car.
While I would do it much differently, it is still intriguing to see others do it, and it gives me chances to see many ideas and look at the approach from many different angles.
I absolutely love the stuff you build don’t ever change you have a great personality and a really cool sense of humor bro
I just love watching you ! Love this build !
I had a 510 in the late 80's, dude I bought it from road races it, so it had like 2" flares on all 4 corners and he raised the rear diff 1 or 2 inches so it was super low with fat little tires, but the rear end barely squatted, tires were tucked up in the wells but they were pretty well straight up n down. It was a total beater, originally red but sun faded so bad it was flat orange. It was a 2 door coupe, woulda rather had a wagon all dam day though. Love the 510's and I love 2t's (two strokes). Can't wait to see how this turns out my man, thanks for doin it.
Love seeing young men take on the Garage rather then the Xbox. Looking forward to what you build out.
I'm 55 haven't had but 2 boats . never knew Johnson Evinrude made v8s, or even inboards. I inherited my grandfathers 1969 Larson speed boat in 1999. id never been out on It but once. Ford inboard 289 HO. garage kept, interior was amazing. I made a discussion to sell it. I was gonna have to tarp it till I built a shelter. I offered it to two male family members they just had done the boat thing and didn't want it. it was cherry he didn't have a lake house so it pretty much stayed in a garage it's whole life. I went with him to a small local lake when I was 14 just to run it a little. keep it oiled up. I was surprised how fast it was. I sold it and the 1976 el Camino he pulled it with, a 33,000 original milage car/ truck😂 looks fun ,you kids teach me something new every day. Subscribed!
Im so intrigued to see this working. Love it!
I'm pumped because its a 2 stroke Vee! Cannot wait to hear it run!
I love how you keep saying you don’t know what your doing, but ya know what that’s how you learn and after a while you will kinda know what your doing 🤪
Just keep plugging along doing what you do 👍🏻
Wish you was closer to me, I have a 1970 model metal ban saw that was in a old machine shop that was still in the building that I bought! I just giving it away but it has to be picked up because I bet it weights 400 pounds or more! Think a friend of a friend going to bring a fork truck to load it! Awesome job young man!! Keep up the hard work you are doing and always keep that great attitude you have!!
Backyard engineering at its finest! Seeing this really brings back memories. It may not be pretty, but if it works, it works
So proud of my son Jim you are a genius. You have a god given talent and you show your showmanship in every video. I love you
Have you decided, or started thinking of how you will do the engine managment system? I haven't yet tuned a EFI 2 stroke myself, but know it can be a challenge. Plenums with 1 TB and no expansion chambers and 8 cylinders probably will make it easy to tune for a EFI 2 stroke🤞
When making a notch in a pipe, just sacrifice a little bit more pipe and allow the centering drill bit to act as the guide its intended to be :)
Also instead of capping the end opposite the throttle body, how about doing a U bend so it can help balance the two sides?
I second this
Hello! Just tuning in. I'd say, In our east/west coast climate. Your diagnosed/w symptoms of "SwampA$$. Suggest getting inside, cold refreshments and a/c. ! Tune again tomorrow..... 😆
I know this might be obvious but it also might not be have you considered the rotation of the engine to make sure it turned the right way for the transmission and rear. Just drill a hole in that plate you have connecting the two upper plenums so you can drop a socket on an extension through it. If you have an extension with a wobble end on it or a u-joint offset adapter that bolt won’t be a problem
This will be a very interesting project for sure,😉👍, don't beat yourself up too much, your still pretty young, just learn something from every mistake, and by the time you're 35yo, you'll be a automotive wizard, lol, awesome video, 👍, and thanks for sharing.
i almost cried watching him fabricate that intake manifold but hey hes gettin stuff done. i respect it.
Excellent job, using shop tools that most shops have and made it work.
Been doing this goofy hot rod stuff since I was about 10 , I'm 74 now and just can't quit , just wanna say I really like your style , keep at it ! I too have "recycled" one of those sign frames someone stuck in my yard , don't throw nuthin' away if it has even the slightest chance of being used....
Love your videos, i think around the 30-40 minute mark is perfect.
I have no idea what's gonna happen, but I'm rooting for ya!
A automotive engineer in the making keep up the good work
Your idea about the intake is something I immediately thought about when you started... The tuned-port injection intake from a mid-80's Chevy Camaro/Corvette.
Cool project!I look with pleasure. I dream of installing such a powerful and lightweight engine in a sports all-terrain vehicle)
I like in depth. and me personaly don't care how long a video is if it's interesting to me.I really like this video and would love to see this engine complete and running in a car.
Very enjoyable to watch.
Length is fine! I'm a old boat racer, enjoyed this as I'm working on a mercury 20 hp in a mini bike.
This is going to be awesome!!!! New subscriber from South Wales, UK 🏴
Since you deleted the reed valves, are you going to supercharge or turbo it ? I don't know know much about 2 strokes but I know it takes a genius to get them to breath on their own.
I'm not sure he's going to have much success..and if he does it's going to sound like pure ass lol
That engine won't run without the reeds. You must have some type of one way valve on 2 smoke intakes. On motors without reeds the piston skirt is the intake valve. Since outboard motors intake is on the opposite side of the crankcase there is no way I can see to make this work without separate reeds for every port. In other words, the way it was. On the down stroke the piston will push the air back out the intake instead of through the transfer port. I haven't watched the entire video, but he should really complete in depth study on 2 stroke theory and this engine. Thinking it all over again, reeds on each intake is a must for this engine. There is another way but you need to be a dynamic flow genius.
100% was considering this as well.
the only other system I know of is a rotary valve, complicated and not really possible on this build.
@@realsonnysullivan Rotary valves work great. They are typically mounted on the crankshaft as that is the easiest way to implement. However, you need one for each cylinder as each cyl is timed separately. So won't work here. I don't see how forced induction would work either. How would you start the engine? Power the blower or whatever externally? He needs to put the reeds and carbs, on individual 90 degree mounts, back on and install the engine carb side up. The cylinders don't care which way the face as their is no oil sump. You could design a manifold and use an automotive fuel/air mixer. But separate reeds for each cylinder is a must!!!
Sticking around for this. 👍👍
Intake volume needs to be at least 2x volume of engine to avoid airflow problems. A skinny pipe connecting everything together won't work. Will be impossible to balance airflow. Even 1 to 1 would be bad but workable. You need to use math for this. Throat width for each intake runner is diameter. Area is 0.25 x (3.14 "pi" x width squared) for example if runner width is 2.5 inches, 2.5x2.5 is width sq of 6.25. Then 6.25x3.14=19.63 is the width sq x Pi. Now multiply by 0.25, so 0.25x19.63=4.91 is the area of each runner. area of runner times 4 runners in this case will put you back at 19.63. To find diameter or width of pipe equal to the 4 runners, have to use formula width equals 2 times (radical Area/Pi) radical is the checkmark with long tail on the calculator. First area divided by Pi, 19.63/3.14=6.25 Now radical of 6.25, that's checkmark 6.25 on calculator with answer 2.5. multiply that by 2, so 2x2.5=5, to get the required width of 5 inches for each intake plenum to be 1 to 1 without restriction.
Area isn't double the width which is a good thing because pipes would be huge otherwise.
The other problem is that you can't run the exhaust through the motor on land. Without the water pumping through the motor and out the lower unit, the exhaust will cook the engine. You have to close the cooling system and use an electric water pump because the outboard pump is part of the lower unit. Heres an example of the exhaust pipes, two stroke tuned.:
czcams.com/video/IcO_2pLqYqw/video.html
The good news it will make A LOT MORE power with pipes. IF you are a good welder you can make them. I think there are pipe calculators online.
I like the more talking, show’s your personality.
Love all of this . 😊
Keep on keepin' on !!
I am so blessed to find a ute, workin on a 510, make this work hito, from gen x , you are why my dad killed all his enemys.
Long and in-depth is great!
I just finished, i enjoyed it though it could be slimmed down a bit
Òened the app and this was the first video that I saw. Your doing it man keep it up and good luck.
I seen another guy on youtube build a bike with a 6 cylinder engine like your 8. He might be somebody you could check out or maybe he could help out with any of your tech problems. Your project is a very cool regardless, cant wait to see it and hear it run.
The intake ports are so large because of that engine has twice as many intake strokes per revolution as a four-stroke engine.
I'll be honest, if you get this project together and running this is probably going to be one of the wildest builds of the year
There's a lot of advice from viewers. Just keep over thinking, thats how shit gets done. Your doing a great job, keep the videos coming cant wait to see the Datsun run...
I like where your going with this build , Heck yeah bra, rock on 👊👊👊
Dude! Ron's muffler shop on the north end of town,just past Stillwell. He can hook you up with pipe and he has a bender. Please use the local guys if you can.
Wow man this video really made the algorithm happy, hopefully it boosts your channel... always good to see more content.
Thanks! I am excited for this build and glad CZcams is too lol
awsome idea. i've wanted to do this myself. one recommendation, DONT sell anything! yet. i think in your last video you we're going to sell the (what looks like) the fuel pump/oil injector assembly. DONT, for now. but either way your on the right track for sure my friend. keep up the good work and awesome content
Your tool collection may be even crappier than mine which is s truly inspiring. I have that same grinder and die grinder. The maroon colored harbor frieghts are total tanks. Love my WEN brand dremmel so maybe i need that mini drill press
As some others have said, work safer and protect your eyes! You've only got 2. ESPECIALLY when using cut-off wheels. They have the well deserved knickname of death wheels. Worked for a guy many years ago that lost an eye when one came apart.
And keep your face out of it's path in case it does come apart.
I thought about using a marine engine too for a future build. I wanted to use the everything from a boat I had years ago.
Steering wheel, seats and other boat accessories too.
There are guys that run these engines on sand rails. They are the exhaust , intake, bell housing etc all figured out and have cad #s for all two custom parts.
G'day from Brisbane Australia mate. Great channel 👍
You can use aluminum foil and a piece of wire or zip tie to keep slag out of things like that when you are welding or just cram some in there, you can even reuse it. If you need to weld near a hole (where a bolt goes, etc) you can pack some in the hole nice and tight to keep from disturbing the hole much and it is pretty easy to get out later. I like the packs with the small sheets of foil, much easier and faster than tearing some off of a roll.
Keep doing what you're doing its great
The engine in the video I mentioned is a Evinrude 300xp
Weld the small tubes on to the long tube then if your tube is 2 1/2 OD you can use a 2 1/4" hole saw to cut the oles in the long tube after the small tubes are welded on.
Next investment should be a belt or disc sander for sure!
not bad kid! you showed up in my feed and the title sounded cool. glad I stop to check it out. you got a thumbs up and my subscription today because I'm interested to see if you can manage this. good luck bud looking forward to following along!
If you weld the tubes together first you can run the hole saw through the bottom and cut out the holes after it’s all welded together
I like the real life in real time videos. Speed up for repetitious tasks. If this was an LS build i would have sped through it all myself lol. Interesting stuff! Oh and please PPE😮
Just drill a hole in that exhaust bracket for a long extension to fit through and problem solved or just move the bracket like you said, they make fine sanding disc to polish that out which I know that you know that. Don't Shazam through the videos your doing fine. Some people try to become the star and get nothing done on a 45 minute video, yours are focused on the content so far. Don't like music videos though. Rather have natural noise of craft going on even though no one is talking. You're doing awesome.
You can always run the intake on top since you don't have to worry about an oiling system. Quite a few 2t scooters back in the day had the cylinder head facing the ground. The joy of two strokes, and if it was still carbs with the correct coil you can run them in reverse with no modifications. Old boat motors you would shut off the engine and restart it in reverse to make the boat go backwards.
New to the channel, but super interested in this project. But my man, edit bro. That was about 20-30min of good content in that vid.
When you leave ok-good stuff out, it means you’re only leaving the great stuff in.
new subscriber from Australia ,glad to be here ,hey mate that Datsun over here is really really exspensive right now ,the 4 door sedans are worth a hell of a lot and the station wagons well theyre damm near priceless ,having said that i love the idea of doing that boat motor swap ,just keep in mind the possibility of still being able to put that L16 back in again ,lookin forward to watchin your other videos
Any and all misalignment of flanges pipes and seams on both pipes and exhaust,cause reflection of waves during resonance. This affects torque
Check the belts on your drill press, use the lowest gear for the holesaw(sorry if you've already done this!)
I know I'm not in a position to tell you what to do because your the one building the cool stuff and I'm just watching but I think a cheap-o plasma cutter would do you wonders for cutting that steel. that's how I've made mine, just plasma cut the rough shape and go to work on the belt sander. That being said your doing some crazy shit here and keep it up!
Hi great vids man, yes you could go to 30-40 minute videos..specially on repeatious stuff.. IE make one or two inlet manifold pipes then cut the video and THEN theyare all done....luv the flux core welding
Some lads in Europe got this to work in a Volvo. It's floating around on CZcams.
The Rudezon. Evinrude 300hp + Volvo Amazon
czcams.com/video/RoiWpJLokEc/video.html
You should have bolted the flanges to a 2x4 or something while welding so nothing moved!
A 4x8 rectangle of steel would allow you to make a manifold with free flow, that includes all 8 intakes on a very uniform, open flow plenum, which you can then attach a single, rather large throttle body to.
I love the hour length and maybe a liitle movie magic but it works good for me
Maybe, you could tack weld the branch flows to the log and use a metal hole saw to cut the holes afterwards or just drill the biggest hole you can and use a carbide burr bit the rest of the way. I wouldn't have thought of that without seeing this though, hindsight, lol. I'm looking forward to seeing how this project turns out, it's definitely unique.
It's a great video...buttt..wheres the chicken from the previous video? Lmao ....keep up the good work bro!
A 5 or 6" cutoff wheel for lines & grind wheel to round corners on the right angle grinder would save you So much time.
Cheers
So a question. On the evinrude johnson the first 1/3 or so throttle is all timing adavance before throttles ever start opening. the throttle moves the timer base under the flywheel. They wont run for crap until you get throttle pick up and inital timing set its called sync and link. the next problem is the 300 v8 waas designed to run at 140 degrees temp. the part you removed under engine is called mid section and inside is a tuned exhaust pipe like exspansion chamber on dirt bike. The thing on first video with electronics and wires is the vro pump it pumps oil and gas then mixes before sending to carbs. these were a pain to tune when new on the boat. Me I would have made it run before doing all this. You know you can rebuild 3 sbc at the cost of one of these. If the ignition box aka poer pack or the stator or the timer base are bad its a lot of $$$ Been fixing this stuff long long long time. I back in the day often thought of these in a little 64 chevy 2 but Id never attempt it. good luck the fight has just begun.
U can adjust your speed by moving the belt on the top
Since the intake intakes upward, you may experience some fuel/oil pooling in the intake runners when it sits shut off. It might be a good idea to add some type of threaded plugs in the runners now so u can drain it if it floods without taking off the whole intake or having to jam some hose down there and suck it out. You'll thank yourself later
We all know why we are here isnt it so?!?😊 WE WANT TO HEAR IT RUNNING FOR THE FIRST TIME SINCE REGAN ERA😅😊
Greetings from Germany 😉
Really curious really curious what you’re thinking for the cooling situation
That was my very first question when I saw the last video.
Tub of water
I've watched a couple other guys put a 2 stoke in a car. I love 2 strokes, light, powerful, no cam, etc. I'll give you a heads up, cooling could be a problem. Marine engines are designed to circulate fresh cold lake water. Put the thickest possible rad with the best electric fan in the car! Also I think you should go throttle body not multi port injection. Whatever ECM you use, they expect to inject fuel every second stroke of the piston. Your cylinders need fuel every time the piston drops. At least with TBI (MAP or MAF) and O2 sensors the ECM should spray what the motor needs. Personally I'd start with carbs..
I just wish he’d finish the coyote in the fairlane!
I bolted a 1x6 to my drill press to save my bits when they pop thru but any cheap or free OSB works too
Dude, just use a flat plate on the bottom... or two if the flanges are not level, weld up 5 sides to the box and 45s over each port.... run fuel and wires inside the box for injection.... bolt the top plate (6th side of the box) down for access. Put throttle body on whatever side makes sense... if you're boosting, build it strong enough to handle the pressure. Look at the inside of a c8 corvette intake to see a sort of close example.
Just drill a hole in that joiner plate so a socket extension drops though. Won't weaken it materially...
2 cycle needs a expansion chamber if you want big power
Why mount the engine with the head facing up? Install it with the manifold up and cylinders down. Functional the engine doesn’t care what end is up.
Look at a Ford SHO 3.4 V8, it uses silicon rubber tubing to connect each cylinder intake runner into a common plenum with a single throttle body.
You don't need to weld it all up together like that. You will need port fuel injection.
On the other hand, why not use the carbs?
In terms of ECU, look at Speeduino and build your own, it is super cheap. This is my plan for a V4 boat engine I was going to put in a racecar (but now thinking EV instead)
If you get this running, you never leav the mystery..
I remember watching a show about Cuba where hot rodders did this very thing. They didn't sell LS's in Cuba so the Cubans made do with boat motors.
Bro it's going to be so hard to get this motor running good I wish you well
I like the way you did time lapse of the repetitive stuff but slowed it down on explaining what you were doing, is the motor going to be mounted to where intake will be on driver side and exhaust on passenger side? Figured since its no mounts made for a vehicle and 2 stroke you could mount it anyway you wanted
I find this highly intriguing.
Great project you r doing, just one thing the plenum tubes diameter is not large enough. The end cylinders are going to be starved of air if it’s not boosted.
In the comments I read the reeds and the oil pump were deleted. You must have separate reeds on each intake port for it to run at all. You now also need to premix oil with the fuel. I strongly suggest you study and understand 2 stroke theory and this engine. Always remember this engine was designed for max HP and any changes if not well designed with 2 stroke theory in mind will likely reduce the HP or make it not run at all. Which is the case if you delete the reeds. I could help you with the basics. I highly recommend The Two Stroke Tuner's Handbook. Learn it's contents and you will be set!
The reeds will go back on , then he will mimic the mariner or lower end carb philosophy with 4 ford inline 6 one barrels feeding custom 4 carb inline set up ,pretty easy to get linkage and fuel supply going .chop the drives haft from the lower run it through a Berkeley jet pump style thrust bearing to a Datsun
Flywheel and Trans plate , not seeing bolting a trans with dowels all that ,let it rip steible box style ,may have to put the radiator s on the roof but it will be putting down 2.5 times original hp and the original Trans will live with 14 inch stock radials or 13s
Or he is planning for lots o boost and some sophisticated exhaust upgrades
Your HP logo is cool 👍I like the piston and rods. Are those H beam rods? 😂
I agree 4 cylinders sound like a lawnmower or hornets.
