- Our 1982 Series 2 RX7 is an absolute beauty to look at but it doesn't run great. We've ditched the carby, installed a new fuel tank and are now wiring it up ready to go to the dyno to see how much power it will make.

Purple burglar alarm! An absolutely epic week of videos coming your way. Strap yourselves in and thanks for watching
Scottish people can't say it haha
Christmas has come early, well done lads
We call them 'lilac thief sirens' in Scotland.
19:20 That electrical TONGUE!
So should we start calling Dave the "Wire Wizard" you know just give him a half a tree branch and a pointy hat ? He could just stand at the front gate of Haltech and yell "You shall not be passed" with a lot of smoke and some flashing lights at every car that rolls out....!!!
I genuinely love seeing the “in the bin” cut, in every episode. Please never get rid of it 😂
I love how mcm touches a bit of everything. Track cars, drifing, drag racing, 90s nuggets, classics, a rotary and offroad 4wds. I think you should also do a diesel project. Definitely check out the diesel scene in Thailand.
I enjoy the variety as well, but diesels are where the line should be drawn lol
Needs more litre bikes
@@toncheky whats wrong with diesels?
@@mickeydee3595 They sound bad, smell bad, and not to mention the smoke. OM606 is the only cool one.
cummings swap 2sexy!!! lol
A big advantage of running premix is the much cleaner burn and less to none carbon build-up, because the 2-stroke oil was developed precisely for that. Great project guys!
I just wish dave could tell me stories to bed, man has a soothing voice.
11:22 "Fire is very difficult to undo." - Dave
Some profound wisdom there! 🤣👍
Dave is always chilled, seems nothing phases him.. just gets on with it.
He's 8 feet
@@nopers2223322 That’s it. Just 8 feet.
@@markm0000 8 feet AKA 40 toes
And he doesn't forget to smang the teat
His cosinus phases are always at the sweet spot
Dave is an absolute legend. I love his haltech series where he goes in depth into the wiring an area always skimmed over on car shows
Guys, you have no idea of how much I appreciate this bunch of videos at this time of the year... Got stucked 10.000kms away from home, been away for over 3 years and this just help to keep myself distracted. It's been a long journey with you guys, wish you the best and thanks for such cool merchandise haha
Rob Dahm sweating while watching this at the thought of being overtaken by the new best rotary channel on youtube.
Rob Dahm only sweating at the thought of owning this generation RX7 but running out of garage space
@@TheRedRaven_ Rob Dahm sweating MCM is using pac performance parts and their guy thinks he's not able to achieve his bs claims lol.. "of course 2000hp from a quad is possible, but with Rob I don't think it's possible" George Rehayem~builder and driver @ Pac performance
You cannot forget the Vargas brothers! They are the true rotary guys! Though the mighty 7 is super sick
This is not a Rotary channel
@@GreenTheScreen123 what do you mean, didn't you hear Marty say "Mightyrerotrarymomdmodmuds"?
Loving how many vids have been coming out lately guys thank you so much. Makes working nights a week before xmas tolerable!
Thanks for keeping the streets safe and free from Manspider and Bastard Man BFM. You're a legend.
I love Dave's attitude!
It's better if you install that coolant temperature sensor before the thermostat to get more accurate engine temperature readings before the thermostat opens.
Good tip, spotted the factory one only after pulled it all apart 🤦🏽♂️ #rotarynoob #learning
@@mightycarmods It'll be fine anyway, keep up the good work!
@@rx7ben name checks out lmao
Don't do what Ford did on my v10 and put it on the outlet of the radiator. Didn't know the thermostat had siezed shut until the pressure in the coolant system finally blew it open and shot 300+ degree coolant into the radiator, completely exploding it...
@@rx7ben Yep, name checks out, and he's not wrong. Oil temp is more important on a rotary anyway.
The thing I love about this car is not the engine, it's the pop up headlights. If I could buy a modern car with them I would.
Pop pop pop up and down headlights
Dont be stupid popups are cool but you can't compare a small aesthetic detail to that heavenly powerband you feel the engine doing nothing nothing nothing then all of a sudden WEEEEEEEEE
Go get u a test drive of an rx8 even c what I mean :)
Those early 80s Mazda steering wheels are killer too. The thin anodized black 4 spoke wheels would look at home in just about anything.
Sadly they will never happen again.pop up headlights are deadly to pedestrians.damn pedestrians
@@lockout6896 i though wind resistant
I owned a RX-7 so I am super into this as a series! Please keep it going, This is awesome. Mine was a 82 and I did not respect it at ALL when I first bought it. Latter I respect nothing more.A Simple incredible machine. I also owned a 1978 280Z and A 1976 260Z. So I understand the competition and rotaries are in a different class and the RX-7 as a whole are as well. Simply a incredible machine that I truly regret letting go.
As someone who owns and has owned RX-7s, they are much happier when you premix the fuel with 2 stroke oil. The factory system uses engine oil which can have contaminates in it, or it can just not work and quickly burn up your seals. Always premix, I'm sure anyone who knows rotarys would agree.
I agree with you for the most part. Though, I think the most ideal is to use one of those Richard Sohn adapters for the OMP that allows the OMP to feed off of a reservoir of two stroke oil. This way you're not using the contaminated oil that isn't designed to burn and it's getting more ideal amounts (not overmixing). That is quite a bit of fab work for the average person though.
It's tough when gas station 2 cycle oil clogs your pump and filter and ordering online is a pretty penny based on your fuel consumption
I've always bought marine tcw3 and never had a clogged fuel filter. Not sure what they are selling by you
I’d just do a son setup if I had another one.

Excellent work guys, congrats on being the best 4x4 rotory channel on TH-cam
But Rob Dahm's 4wd 4-rotor RX7??
I love everything about this. Respectful and sensible updates that will give this beautiful girl another 30 years of braap braap braap adventures. Well done Marty 👍😀
You've probably heard this a bunch of times, but the reason for all the Mitsubishi logos on parts is because they'll be from Mitsubishi Electric, so it's not directly parts from Mitsubishi Cars. Mitsubishi is a large Japanese conglomorate with offshoots in lots of different manufacturing segments. So this is more kind of like finding Bosch parts in your car.
It makes sense to add certainty through EFI but looking at that old distributor you have to admire the engineering that goes into making a non-electronic self-regulating self-adjusting ignition timing device without any kind of logic controller/processor.
You could say that it was a mechanical/analog controller instead of an electronic one.
You guys are inspiring me to bring my first gen rx7 back to life. All the stuff youre installing on it gives me hope that i can make mine run good again
Everybody that works on car electronics should have a dave
Dave & Haltech... Definitely a WINNING combination. Dude is the shiznit!!!👍👍
I’ve been rewatching Initial D, so seeing an RX7 is pretty sweet!
Hello fellow JR
Maybe this could be the RX7 that belongs to the Takahashi bros dad 😂
Do you feel similarly about a cappuccino?
@@jdmglobalwarehouse could well be! But just passing it white, add a bonnet scoop and a turbo for the White Comet!
@@Oblithian just watched that episode yesterday! Kei cars are fun, I wonder what engine swaps would be available for such a compact car.
My favourite cars off the show are obviously the 86 fully upgraded, and the RX7 FD as it’s just such a sexy machine!
Dave has this amazing calm vibe around him, his voice is so soothing. Imagine him reading to you from your book every night when youre going to sleep. Bam youre out like a light.
I should try doing some EBook narration?
Dave starting to sound like turbo yoda in chill mode I love it. The haltech crew is just the best.
Greatest Quote I heard this year is by Dave
" Fire is very difficult to undo" .
I love when a strong powerhouse motor is a nice tight small package.
First time I saw a rotary out of a car I was amazed
I love Dave - when he shows up, you know it is all about to happen. He needs his own nickname, like Yoda and Stig. He is definitely a guru when it comes to this stuff! E-Wizard?
I was just about to comment that Dave needs a nickname!
E-Wizard is perfect
Only 4 hours online and so many spam-bot-comments here...
Hopefully this car will live for so many more decades, especially after all this presentation of great hobby-work on it...
I love your work guys!
Yeah and we've nuked at least 50 of them...
I like the fact that head light popper uppers was used as a description, thanks Marty for throwing that in !! :)
good to see another episode of MightyNoRodsRotorMotorMods
I love the song around 15:30 with the little piccolo snare drum rolls.
This episode is excellent. Thankyou. Good info, good tooling, techniques and the vibe is just so chilled. Love it.
"Fire is difficult to undo" 😆 lol
You guys sent nice stickers to RobDahm, you guys do love the rotary, go ahead and admit it
"When the piston reaches top dead... kidding" 🤣😂🤣😂
Love your content quality work as always thanks for keeping it fun and varied for so long guys! Cheers to another year full of adventures.
I love the little dis towards the wreckers that sold you that boat anchor of an engine.
Everyone loves the sight of a wizards sleeve
Beautiful seeing new technology keeping old history alive.
MCM killing it with these uploads... so good!
That pre intro with moog doing the goat scream made my night 😂😂😂
gotta love a visit from Dave, what a legend
Love this episode, good old wrenching on old cars, well edited, well explained, no merch-pushing and no smacktalk from Moog
Dave is the GOAT with wiring
Dave is my favourite cameo member of MCM. I'd absolutely love to go for a pint with him. So chill.
It gets pretty wild, there is never just 1...
Lads! I got my Ultimate Edition in the mail today.
I’ve been watching since the driveway days, and just wanted to drop a quick note to say thanks and happy crimas/safe holidays.
You’ve made a positive difference to my life over the last decade or so, so cheers for that you absolute legends.
All the best to you two and your fam closing out 2021.
Wizard sleeve sensational bit of kit. Every man needs a nice sleeve
Wizard sleeve sounds like something you'd find on bad dragon..
Thanks for the videos Marty and Moog, your vids always make my week more enjoyable. Much love from the States!
Loving this build. Such special little cars.
Its a good idea to get rid of the stock oil metering pump setup. It injects oil from the sump so you'll have to check oil level all the time. Also, synthetic oil is much better for rotaries given the high temps, but it apparently doesn't burn as clean as conventional oil, so no OMP is best way to go. That way you run 2 stroke oil in the fuel, which is designed to be burned and lubricate in that environment.
Mad episode! Super satisfying to watch.
BEST ROTARY CHANNEL ON THE TH-cam. PERIOD.
Mitsubishi made ignition systems for lots of companies. Did you know the LS motors had a Mitsubishi ignition on some? Mitsubishi was actually the only company that could manufacture an entire car from the material components. From raw metal plastic into a finished vehicle. What a shame they withered away
loved the intro! actually got an audible chuckle out of me!
Best Off-Roadtary-Channel in the world!
After watching rob dahm fabricating entire rotary engine housings and custom dowels, i don’t feel so lost anymore. This shit is a lost art form. It’s like learning a new language
Mcm
An absolute staple
Before fullboost
Before binky
There was moog and Marty
Aged like a fine wine
Never wavering
Just like “that 70’s show
You can always come back to these gents and just enjoy.
I must admit, I had stepped out for about 5 years, I reckon I came back around the lotus episodes, but what can I say, the guys haven’t changed a bit, nor have the cars I grew up with (I’m 35 now) just absolutely magic to see the guys still tinkering away on these absolute classics.
Don’t change for you,
Don’t change a thing
For me.
(Also, don’t get over excited and try Experimenting with asphyxiation whilst masturbating)
Keenly waiting on the new brz story un fold, keep up the good work.
Hell yeah sitting at home with nothing to watch and this pops up sooo good
Can’t get enough of in the bin!!!😆😆
good stuff fellas! ! ! One tip, don't use synthetic oils as it will bugger the apex seals.. ;)
Mighty no-rods is putting along nicely. Well done, boys.
Clicked before the notification had even a chance to ping me. YEAH! :D
give it 2 more episodes and they start with this is obviously the best rotary channel on the interballs
Epic! Can’t wait for the dyno
Loving the rota content, thanks boi's.
With oil Injection, pre mix 2 stroke oil is better, but when you have an IDA type set up, can just set factory oil injection to about 1/2 way premenant. Make rod out of wire that attaches to oil injection pump and at other end wrap around rad hose. Getto but works! Run my 13BBP like this for 8 years now.
You guys have the best intro bumper music!!
That intro though, what a tongue twist! 😂
I loved my 13B FB. How could I know it would be the best car I ever had.
Love the “IN THE BIN” clip.
Honda prelude gen 3 2.0 twin carb in white black .... best car i ever owned and great sound aswell
I've never been much of an mazda fan but this car just looks so cool to me
thatll never get old. IN THE BIN
Can't wait for the Christmas special. Guys loving the content ive been a big fan for a very long time now. Keep up the good work Marty & Moog. Merry Christmas and a happy new year
Im super pumped to see the most inefficient and noisy 85 horsepower ever made.
Eh they made 87 to the wheels brand new and its super easy to pull more power out of them.
you say noisy like it's a bad thing, when it comes to rotarys, it's not
@@mightycarmods haha true, but man have I heard some epicly bad exhaust mods on RX7s and 8s, specifically non turbo models sound terrible. Basically a civic that spins out to 9000 rpm. I love my noisy cars, but every car ive ever owned sounds like ass. 370 nismo, porche cayman S, focus RS. Had one exception. WRX Sti.
That little cranberries zombie cover ... so good 👍
Loving this video guys. Is it possible to do a cost break down on such a conversion? I'm sure I'm not the only one who'd like that.
Keep the great video's coming guys.
I love the Rx7 SO MUCH! Keep the content coming boys!!!
You had to say it. You just had to say "You can't kill these engines." Watching this now for the first time but I see the title of the next video lol
If you are having trouble finding a CAS, you can do a trigger wheel setup with a hall effect sensor. Full Function Engineering makes one (look for the FC one) or you could build it yourself. Another option if you want to avoid premixing at the pump in case you loan it out could be to use an output from the Haltech to a separate premix reservoir pump. Rotary Aviation used to make an adapter to use the stock pump to do this, but they only make them for the newer rotaries now.
ECU controlled solenoid to control the oiler and then map it up to work alongside the TPS
You could set it to give more power just like Ferrari did with their F1 engine 🙂
@@stevejones9788 I never knew Ferrari had a rotary engine 😜
Love this project guys. Keep them coming!
Great video, watching from Syd
Nice..exactly what I would like to do to mine! Thanks for the entertainment.
man can't wait for the next video on this car. im a mazda fan and i love the ideas of making old cars get new tech.
They just uploaded it
You can buy kits online to add a separate 2 stroke reservoir to inject oil into the engine in place of the factory oil metering pump which uses dirty crankcase oil! Much easier than premixing as well.
From experience they don't work as well as the factory OMP as they rely on gravity feed to create head pressure. There is zero problem with injecting sump oil in a rotary if the oil is changed regularly as it should be. I have witnessed tear downs of engines running on straight LPG and OMP and the engines are perfectly clean inside. Unburnt fuel is what clogs up engines with carbon not unburnt oil.
@@gregpieris4478 interesting insight thank you. The kits I've seen include a pump of sorts to help with the injection process. I'm not saying there's anything wrong with injecting crankcase oil but I don't like the idea of constantly topping up my oil and checking the level while worrying about running it low.
@@PhantomShane914 the factory oil metering pump is in fact the pump, the kits you have seen just extend the keyway for the factory pump. But the feed for the pump in the factory front cover gets constant flow under pressure from the engine oil pump. With the adapters, it relies solely on gravity feed, and i was not satisfied that it actually delivered sufficient flow under all conditions compared to factory setup
Nice. I really hoped to hear it run. Next time, on mighty no rods!!!
i love how the new distributer looks like a piston but had a spinning trirangle in it
a wizard's sleeve has two meanings over here!
19:20 ... THAT ELECTRICAL TONGUE WIZARDRY IS NEXT FUCKING LVL M8!!!!
good on ya KENT
Yeah, wow... that is weird!
Got lost on the word "rotary" 🤣
Great job,love to see new stuff on every episode.Love you guys
Have a bunch of the crank angle sensors laying around from my t2 rc7. Didn't realize they were that rare!
Thanks for the videos legends!
Ugh. I thought we were gonna hear it running but alas, cliffhanger . Looking good and love the content 👌
Ahhh the RX7, we all wanted one back in the day but no one I knew could afford them.
