Make sure you guys stick around for the back half of this video to really see us fry the tires off!! 🤘🇺🇲
Cleetus McFarland needs to have this when you're done with it
It's the earcracker
Absolutely love this 2 stroke exercise of genius. If you’d like to shift the transmission while you’re driving a dog box conversion would be pretty easy for that 5 speed,pretty much just a slick shift setup like you’d do a Muncie, A-833, Toploader or T-10 trans. Heck,if you shop around there are plenty of those RX7 or RX8 transmissions around from the road course guys that have those trans faceplated. If you want to shift it at wide open throttle after either of those mods just add a strain gauge on the shifter wired to a timer that kills the ignition for a few milliseconds and you’re in business. With those updates you can take of in any gear and up shift at wide open all the way to fifth. 👍
Yessir!w
I just found one of these with no engine for 500 bucks near me. It’s kinda tempting
The fact that the guy even made a beautiful hood that looks like it was made to be there is just... WOW Im at a loss for words. This guy is quite the fabricator. Hope he continues making things like this. He needs to make a youtube channel. NOW
yes looks good but maybe if he rigged some rubber motor mounts it might clear up the vibrations. that said his skills are good.
@@teknowil it was mentioned exactly why he can't do that yet. The clutches have to stay perfectly aligned..
@@samuelmurphy8692 And I think even the way he was talking about adding them in the video will be quite difficult. The amount of absorption wont be very much.. though probably still much better than it is now.
Lol that hood looks like its part of the back to the future delorean. Insert garbage there
the bonnet is real cool.
My recommendation, as a long time Mazda tech, is to always purchase a RX7 or RX8 with a sunroof. Once the engine loses compression you can always turn it into a planter box.
I didn't know RX-8's came with sunroofs....
At least all SA/FB RX-7’s have detachable roof panels.
@@tlove2108 mine has one. I wish it didn't... Gives you much less head room
@@tlove2108 I actually haven’t seen one without a sunroof until this day, only on a magazine once
Or make one of these
There’s a cylinder shim kit for that engine that adds about 20 hp
They should add it!
So much that could add power upsize carb ignition porting squish gap transfer timing etc
This has got to be one of the craziest Junkyard Digs videos I have ever seen.
A snowmobile RX-7.
A Cessna 510 in somebody’s front yard.
And
Drifts and burnouts with only 60 lb-ft of torque.
I love it!
That's what I love. Here in Germany, if you only think of starting this frankenstein in your driveway, there are already 3 police cars standing there and asking for some approval papers, registration and street legal TÜV stuff. But in the US? Yeah, lets rip this thing down the road and have fun :D Mooks face is priceless and kevin is getting the real tokyo drift vibes xD
Grüße aus Südhessen Xd
That stinks. The police here pull you over just to take a closer look.
Exactly 😂😂
It depends on where you live. In California, they pull you over, arrest you, duct tape your eyelids open and force you to watch 49 hours of Greta Thornburg speeches.
at least you guys have the autobahn, i went to jail for doing 100mph lol
You should make a gas cap flip option for the pull start. Just walk up, flip the little door open, and rip the cord.
Great idea!
Route it into the glove box. lol
Run it through the key ignition 😂
@@owendeliebs1894 imagine the sheer confusion of anyone trying to steel this car when they climb in and theres a pullstart where the key should be
That would be tye oddest shit
Austin seems like a cool guy!! What an out of the box perspective on a swap. Badass!
I can only imagine how Mighty Car Mods would feel about this since they got their RX7 back in shape lol Austin did a hel of job to make something so wild and unconventional work lol
The builder of this wonderful machine is a pretty cool guy! He would make a good team member of Junkyard Digs !!
That would be awesome
I appreciate the kind words !
@@ShakyBonesLLC I'm a rotard, and normally put off by non-rotary RX7 swaps- But I gotta say, you did one hell of a job smashing convention on this one. I don't think you could have picked a more perfect powerplant for such a thing. Well done, sir!
@@DocSprocket haha appreciate that very much!
Agreed
So, this thing is basically a CVT Automatic but with a choice of five different final drives due to the manual gearbox behind the CVT clutch? That setup actually kinda awesome, because you can change on the fly if you want a shorter total gearing for better acelleration or a longer one for more speed.
Bingo 🤘
The CVT is not a clutch. It has a centrifugal clutch.
@@totalyep lol
@@totalyep float the gears. Shouldn't be done while accelerating but should be able to cruise in 4th or 5th
@@totalyep "a banana is not a plant, it's a fruit"
The fact that this RX7 isnt LS swapped is a thumbs up in my book. The look on Mooks face is priceless. 😊😂❤
Instant smile maker. Both Mook and Phoenix just had these great foolish grins on their faces! I love it!
I think I saw every emotion Mook could possibly have while being in that car. Fear, Joy, and Excitement just to name a few.
Digs and mook have this chemistry that just radiates both chaos and like 70s/80s styled high school sweethearts romance. They both just always look like they have the absolute most fun together.
True story!
agreed
beauty of youtube,smile,look happy...
If we were all this lucky to have it would be heven
I'm watching this so late but absolutely the best part is Austin's reaction to "Do she spin em?" fucking awesome man he almost looked disrespected 🤣
The CVT likely contributes to the fast 0-60 time, as the light motor stays in its power band and doesn’t have to rev up during each shift, not to mention no acceleration lost in the shift points. And the car looks super lightweight!
The original light rotary motor put out 105 hp and the same amount of torque .This motor sourced from a sled put out 160 hp and most likely less torque , so not surprising to obtain such performance , cvt or not .
Name: Mazdoo. So crazy it is cool. Consider putting the end of the pull start outside the hood so it is easier to start. 🙂
Pull start under the hood is "anti-theft".
Nah, make a linkage so it comes out of the dash.
Mazdcat
If you could somehow rig up the clutch pedal to be a kickstart that would be cool.
Or put electric start on it
I love everyone’s response to “Do you want to drive it?” followed by a quick “YES”. Then the reaction to how you start it.
What an unbelievable concept. I believe this could truly be improved on a level that most people aren't even thinking of
I love it!! I've got a yard full of snowmobiles. My mind is running with ideas. That's totally tweakable.
Do it !!!!
This is one of the coolest things ive ever seen and the guy that built it seems pretty cool. Mook is awesome. She displayed like every emotion with this car.
My Formula Student team used a snowmobile engine with the CVT clutch. There is a lot to be gained in performance by optimising the weights and springs in the primary & secondary CVT spools respectively. If they're available for the CVT you have might be worth buying a weight & spring either side of whats in there and doing a bit of trial & error.
I second this! possibly lighter weights on the primary to bring the engagement rpm up higher for better take off. those engines really like the higher end.
What snowmobile engine did you use? I'm assuming formula SAE, correct?
@@connorbabcock8197 Yamaha Phazer 500 twin with smart car turbo. Was quite a heavy package and the car was not super competitive. Was higher power than most of the field but hard to drive well without practice as the power delivery is so different. Also heavier than the single cylinders.
The smile on Mook face on that first ride just priceless Kevin @Junkyard Digs
having helped rebuild and work on rotary engiens many times over the years thanks to friends who are into such things, they can be incredibly reliable given you treat it right and understand what your using.... honestly, the rx7's engines can be quite impressive, and, i have seen well treated ones go over 100k miles without a rebuild, (those also were given the oiler mod so proper oil for buring could be used rather then oil pan oil, thats designed not to burn and often leave deposits or fed with mixed fuel with 2 stroke oil already in it.. outside that... just understand what you own and how to treat it... for all the shade people throw... they can be alot of fun.
I've always been a fan of rotaries the way they run and drive is incomparable to any other car, most people who throw shade have never even sat in a rotary car and its sad to see people jump on the hate band wagon just because everyone else is, these engines don't deserve the hate they get and i hope someday that will change
Agreed, I hate when people claim rotaries "aren't reliable".... literally one of the most reliable and simple engines there are, people just don't know how to use or maintain them thinking they're a piston engine.
That's an absolutely hilarious build. Props to the kid who dreamt it up and props to you for keeping her alive. I can't wait to see what you've got in store for it.
Needs a turbo! Ski-Doo has done it with their 850 snowmobile. Come on Kevin, you and the guys have made a lot of cool stuff happen, let's see you turbo an engine! Call Cleetus McFarland if you need to! 😉😎
Or a 100 shot of giggle gas
Yes, and also, if you get a newer snowmobile two stroke engine, they have built in electronic reverse, so you can skip the gearbox for weight savings. You might however need to change the gearing with a chain drive, but it's still way lighter than the gearbox.
What it needs really is engine direct hookup to transmission
The Turbo 850 is best at home at high elevation. It was made for the mountains.
My thoughts exactly!
Long time watcher, first time caller... fellow Iowan from Decatur county. I've lived in Georgia since 2014, your videos remind me of home. I just have to mention I just absolutely love the relationship you and mook have! She's a hell of a woman! I wish my wife would get as excited about a car as I do. But mine always supports me and the stupid purchases I've made! She never makes feel guilty when it enevedly ends up being a horrible purchase 🤣🤣🤣
Living in Canada I thought I had seen everything you could do with a snow machine. I stand corrected. I'm jealous.
Just a suggestion, a form of vibration nuisance control that I learned from a friend that competed in car stereo competitions ( he had many, many trophies), RTV silicone each and every body panel brace and be VERY sure that you get in between the body panels and bracing. Use the plastic interior panel wedge tools as prying tools to open up any potential gaps to assist in getting the RTV where it needs to be and don't skimp on squish out, it is all the better.
Or use expanding foam
All that and a proper muffler would do it justice.
Probably wouldn’t hurt to swap out the solid engine bushings for something a little softer
Unfortunately the engine exhaust cannot be reconfigured. It is optimally designed for most power.
@@neilgelinas9926 an expansion chamber is not a muffler. You can have both.
7:08 this moment was absolute gold lmao what a perfect question to ask
7:10 is such a bro moment, “do she spin em?” “oh yeah” 😂😂
Men
Oh yeah.
BRAAAHAAABAAARAAAH
That car is pure automotive debauchery! It is wonderful! I love how it brings a confused smile to everyone who came in contact with it. Can't wait to see what happens with it!
Two things: "why the hell would you do that", and "I love it".
Put wings on it and it might fly??
😂 "I can't feel my legs"...
All the hard mounts. 😂
-and I love it!
4:35 that laugh gets funnier each time, so full of joy. Sounds like Rex tripping pistachio in the restaurant on master of disguise.
Red Green would be proud. Almost as good as the gullwing door Maverick. "If the women don't find you handsome, they should at least find you handy!"
I love the engineering that went into this. That takes some imagination to pull this off.
Keep Yer Stick On the Ice!
Red Green was the pinnacle of manhood growing up. What a character he was.
Being in Chicagoland and looking at Marketplace oddities myself, I saw this monstrosity and puzzled over the hood construction and swap concept. The novelty of the audio alone makes it Kevin-worthy for amusement. Thanks for sharing! Call her Ruth Buzzy?
I remember seeing it too (Joliet area)
too weird for my taste
Lol. Hi Dad
Cheers to you Mr. snowmobile RX7 builder! this is awesome
Crazy ride, the look at her face first time riding it😁
I've been a mechanic for over 20 years and that's one of the creative swaps I've seen! Fn hilarious! 😆 🤣
Just helping out here: For the motor mounts, I suggest looking for mounts that apply to a 1975 Volvo 242. It's just a hockey puck with studs on both sides and a steel plate on one side. I used one in my Mazda B2000 build when I dropped an OMC Cobra 2.3L (almost identical to the Pinto engine) under the hood because the original Ford Courier mounts in the parts catalog weren't the correct part. It's the same truck, just a different grille and came with the same basic 2.3L from factory. It came up with the vertical Mazda mounts, not the flat horizontal ones for the Courier. Two pieces of angle iron and the Volvo hockey puck got the passenger side mounted securely. Just for reference, the Anchor brand part number is 2427. I'm not affiliated with ANY corporation, mind you.
Alternatively, use the mounts for a 164... A little stiffer, but a lot softer than the solid mounts that were used in this application. They also have the studs centered, instead of offset, which is how the 1975 240 mounts (also used on later 240s on the driver's side with the overhead cam engines) are configured. The 164 mount is Volvo p/n 1206614, versus the 274110 Volvo p/n for the 1975 B20 mount.
i used to own the B2600 4wd version manual high and low gear years ago
At that point, why not fabricate it with a hockey puck
@@isaactrockman4417 Only if the hockey puck is cheaper. I checked on Rock Auto and they were about $4 each plus shipping.
@@JVHShack oh wow
The fact that it's pull start makes it RULE !! That is so cool. When he said it only took him a week and a half to build this I was surprised. To me, that's FAST. Man, that car gets 1000 smiles to the gallon.
Mook makes this upload ,those facial expressions are GOLD
Adapt a factory flywheel to the snow mobile clutch with better bearings so you can clutch and shift and mount the engine like you thought to the transmission would not be very hard at all
😆 The clutch moves... It gets narrower at high RPMs. You could NOT attach a flywheel to the clutch, and expect that to work. You'd have to lose the clutch all together, and attach the flywheel directly to the bare engine output shaft.
This may have even the greatest junk yard content ever . Great edit , great camera work . Definitely top ten ,diggin the digs .
Love STEVE!!!!!! One of the best car channels on youtube.
For the winter time, I guess you would take off the tires and put skies on.😆😂🤣
Mazda Rx800
Thats unfair timing
i like that mook puts up with your stuff. she just smiles and says yes dear, I'm fine.
Plus, the more you think about it, the more genius this idea is! With the high revs and high gearing of a rotary, a 2-cycle is the perfect swap!
This is 360% HILARIOUS!!!!! Made my day!!!
i'd love to see that thing with a proper transmission (no CVT), a reworked expansion chamber, and maybe a better muffler so you can put the stock hood on so it's a relative sleeper.
In honor of what it is run the chamber through the cabin lol.c
bolt it to another one and make a frankenstein inline 4 so the vibrations balance out.
Cvt is why it works. A sensible muffler is needed. But cvt are used for a reason. Big 3 us automakers could make it reliable but v8
He just have to replace the cvt by a chain or another straight belt the trany is allready there
Personally i'd ditch the CVT and direct drive using an adapter plate with clutch to the original 5spd box. Make some decent mounts so it doesn't rattle your bones and clean it up a bit. It's a great idea, however with some polishing touches could be a really cool car
An adapter plate connected to what exactly, how would it even hold fluid
I'd definitely buy something like this tbh
I would also get a aftermarket exhaust system with sound cancelling insulation for the engine compartment and interior. Having a car that sounds like a chainsaw is riding shotgun could get old really fast. .
Power band is so short lived that where the cvt comes in keeps engine in the power band if clutch ramps are right along with flywheel weights to shift properly
@@Mr.Safety. what fluid? There is no fluid between an engine and manual trans?
That is so cool! Nice home build guy!
Well hell yea, that pull rope start got me too, that boy who put that thing together exhibits some true southern engineering skills for a feller livin so far north,just had to like and subscribe kinda got pulled in ya know!
Just the idea of having a pull start engine makes me want to build one
Until you stall the engine in a busy tunnel
@@oi32dfCan't stall a CVT though!
I like that when the RX7 does a J-Turn or burnout the closed captioning says [Applause]
I think it's just saying what we all are thinking. Lol
CC is constantly telling the deaf that there's a party going on. Most beginnings of videos contain applause, even when nothing is happening.
7:09
the way he responds "oh yeah." in that tone and then just absolutely rips a donut into a burnout
the final drive clutch is on backwards I am amazed you never noticed !!! flip it and dyno again !!!
Pretty sweet ride! I would definitely have to slap some dynamat on the firewall and floor and redo the motor mounts for less vibration but definitely a unique vehicle.
Have you ever smiled for 35 minutes straight? Well I just did!! Even though this wasn't a will it run type of video this was amazing to see. Please keep up with the new and different content! I can't wait to see what's coming next.
This is a really creative idea with some excellent execution. That being said, as a fan of the rotary and especially the 1st gen RX7, this hurts me a bit.
Tbh you still get the general brappiness and it’s way faster
Same here, while the car looks pretty fun and took some creative design to execute, it once again hurts the RX-7s and reinforces the reputation that these cars in their stock form are "waiting to blow up" and that the car itself is "only for for swapping something better in" even if its an objectively worse engine, i love these cars and the rotaries but they are very misunderstood and while i love engine swaps i would prefer to see MORE rotary swaps instead of rotary replacements
It’s the one engine swap that makes more blue smoke and obnoxious noises than a rotary… I love it.
I’ve wanted to build a simple carbureted 2 stroke powered first gen rx7 since my teens, when I first saw this vid I almost creamed myself, the only problem is it uses a cvt. I really wanted to hear it rev up through the gears
@@motoredbikemadness2061if you take out the cvt and make it use a clutch it'll work
or you can directly connect it and rev match every time you shift
The fabrication quality of the engine mounts, hood, and exhaust system look really good. Who knows what other cool projects the builder has come up with. Might be a good car for rally cross, but a shame it isn't practical as a daily driver. My suggestion would be to cover any metal inside the cabin with dynamat, like what is used under carpets and behind panels of powerful car stereo installations to cut down on the excess vibration. if you want to keep the cost down maybe contact cement and carpet remnants could make riding in it more bearable. Your wife or girlfriend likes the car which is always a plus.
I like how this guy seemed upfront and honest about what he was selling...I would be comfortable doing business with him
Ski Doo had a snowmobile that was Silver and its name was "silver bullet". I think that would be a good name for this "Silver Bullet" . 👍
The Silver Bullet Ear Bleeder!
Silver Mullet?
This thing is so epic!!!!!
Dope af!!! I love it!!!
good lord the pure joy in Kevin's laughter is infectious xD
😂 that thing is amazing. Nice score
Saw this thing on Facebook a while back and was just astounded as to how this got put together. For someone to come up with this is just insane!
Props to Austin ...Hell of a game there !!!... i mean you have a bad day at work ? Take this for a ride and you are ok....sweet
I don't see too many of these vintage RX7's around my area, so when something like this is sitting in a parking lot come summer time I like to take pics. So hopefully you don't hack it up too much. Would it be possible to fix the expansion chamber so it's not doing such a sever 90-degree turn? I haven't had too many snowmobiles myself so I'm not familiar with all the engines. If this thing has reeds in it and not some weird power-valve setup like in the Rotax engines you might be able to get some more go out of it by putting some performance reeds in it. Also get yourself some Dyna-Mat or something similar by any maker and do up the inside panels of the car. It'll help big time with soaking up your vibration problem. If it works for subwoofers it should help with this. :)
Keep advancing the build. It’s a great start to something even more awesome.
This is by far my favorite of your videos!
So glad you bought this, subbed!
Absolutely epic! It needs a pull start extension to a handle in the dashboard! Maybe throw the snowmobile single headlight into the front grill! Keep doing what you do!
I've never laughed so hard as when you took it for the initial cruise, that car is something else! Love it!
To cut down vibration you might wanna line the interior with butyl rubber sound dampener. It helps cut harmonic vibration. Might help to do the engine compartment as well. Idk how much it will help but it’s worth a shot.
Man i would love to see more content with this thing! It’s definitely interesting lol
So funny to see the RX7 but then hear this Snowmobile sound to it 😂😂Reminds me on my Trabant but this RX is waaay louder,faster and cooler 😄👌🏽
I would call it The Bone Shaker
You need to make a video of taking that to a Mazda dealer. Possibly asking them why it's so loud or hard starting just to see their reactions.
This is a god tier idea
thats really cool have lots of fun
That thing really is crazy. Some quality of life refinements to reduce the vibrations would be good (from interior panels, etc) and exhaust noise etc and it'd be a lot more fun!
Of all the ridiculous things you guys have ever bought this is probably the most awesome! You definitely need to race it somewhere.
Might be fun to fix the hard mounts on the engine so the NVH scores somewhere below 50 on a scale of 1 to 10.
Absolutely hilarious! 🤣 Am more than a little disappointed that you guys didn't try to do *something* with the snow around the parking lot. I mean, come on, a snowmobile powered RX7 on snow tires? But am sure it'll snow in Ames again soon, if it hasn't already since this was recorded, and things will be set right. 😉
I LOVE that body so much, and seeing you drift it around 🥰🥰🥰 damn… wonder how much a swap like that costs..? 🧐
Favorite line: "Somebody needs.. . We're gone fix that"
lol
This was one of the best videos! If you don't get over a million views on this I will be shocked! Only things I would definitely change is it's almost a necessity that you got to have some rubber motor mounts. And I would probably try to rework the exhaust that way it's a little more free-flowing. And then if it's carbureted definitely a jet kit in the future. If it's EFI definitely a tune. Either way this was such a bad ass video, absolutely made my day too!
Auston did an amazing job building it! I love it. Yea maybe try to rubber mount the powertrain, and put a headliner in it...... You referred to it as the "Thing" a few times.... what a fitting name!
Putting tracks in the back and some skis on the front wheels would be hilarious
awsome video kevin thats something you dont see everyday a car with a snowmobile engine in it i seen one in a gator but not a car thumbs up and shared
"Does it spin em?" Scoffs "oh yea!" Proceeds to whip that shit 🤣🤣 that was gold 👌
Oh man this thing is awesome. I’ve always had a fantasy about putting a Polaris XLT engine in a Geo Metro with expansion chambers sticking out of the hood.
This thing is dope……. I’d totally sport this ride around every where!!!!
Paint it!
Give it interior upholstry, it'll be quieter in there! LOL
That is one of the coolest builds I have ever seen.
This opens up a whole genre for builds . Imagine what could be done , a hybrid possibly, electric /snowmobile powered .
Mook was trying so hard to not smile, but she couldn’t stop it. Lol!!!
Im here because junk yard digs is next after every cars and cameras video .
Cool car mobile
LOVE IT!!!!!!!! That's exactly the kind of thing I'd build, I am really jealous, I can't wait to see what you do with it. The expressions on Mook's face were priceless, she looked like she might mess her pants in a couple spots, hilarious!!!
I liked the Fairmont in your commercial for Squatch, I used to have 2 of them, very reliable cars.
