2JZ WHO??? Building An Actual Supra With Vortec 4200 Power

[@wolfgangsgarage1693]

My vote is some tiny twins. Cheap budget and fast spool. Use internally wastegated ones to keep space.

[@umakemerandy3669]

Yup

[@JamesJames-r8t]

But weeeeeeee weeeeeeee 😢😢 no weeeeee weeeee needs weeeeee weeeee super charger go weee weee weee 😢😢

[@james10739]

Compound

[@Christdeliverme]

@@wolfgangsgarage1693 nah it won't sound very good at all

[@Low760]

No need now given the efficiency of modern ball bearing turbos

[@pob_car]

Super high compression, aggressive cams, maybe some spray if that tickles your fancy. Sounds super cool Also another guy said ITB’s so that too

[@pob_car]

Wow you already have the pistons. Definitely go for it!

[@cj09beira]

+1 for the spray that car deserves to look its best.

[@pob_car]

@@cj09beira spray meaning nitrous lol

[@bussingwithbain]

I am all about putting a turbo back on it. Already has the badging,and you have the skills!!

[@danielkoch6815]

I'm an inline 6 guy who tried to build a 300 HP 4.2 Jeep engine for my Javelin. It sounded NASTY, but ate itself soon after. I say build the NA version so I won't have to!

[@zandercraft1168]

Because of your videos, I'm planning to put a 4200 with an ar5 into my 82 celica supra. Never thought I'd see this video from you. Please continue!

[@reedjacksonmaccom]

I like how you described what you like about the Gen3. Nice compliments to the original builders.

[@ethanschocke333]

i believe it being a turbo supra you should make it a 2jz killer build. 5-600 horsepower on a haltech or link. just a fast streetcar you can genuinely enjoy daily.

[@michaelpaulson8281]

Got an old jaguar xj6 I'm putting a 4200 in... Sadly got two projects going but seeing you guys keeping the dreams alive makes me want to bump the jag to the front of the line

[@douglasmcdowall5006]

I knew that car as soon as I saw the thumbnail! I'm happy that you ended up with it and that it's getting revived. That car led me to the 4200 builds and eventually to your channel years ago.

[@jlsracing997]

Best looking Supra they made. Absolutely love them. A pro touring build or something with good horsepower and good handling for the twistys.

[@djasseater2262]

Mk 3 is a work of art, mk 4 is a bloated pig.

[@Numer1Polak]

The reason they are so heavy was because the mk3 was moving away from the sporty category and more into grand tourer. A Comfy two seater that can be sporty. Dollar exchange rates, economy, and tariffs. Forced them to make em higher "class" vehicles meant for more wealthy buyers, to keep margins higher. So they had thicker metal, double walls, sound deadening, plush automated seats and so on. Still one of my favorite toyota cars, they just look like a slick box and I love that.

[@bertvisser6423]

I remember those videos,hard to find info back then,very cool you ended up with that car

[@MinisterofDOOM]

MARK III HELL YES. This is unbelievably cool.

[@GodlikeGTZ]

My 88 Supra was an unexpected gift. Now I'm obsessed with it.

[@dennisbonge002]

Sacrilegious at its finest. I approve this build

[@lemmehaveone]

High-compression naturally aspirated would be really cool and unusual, especially with ITBs!

[@SNOFLOFilms]

I cannot believe you ended up with this car. That video was also my introduction to the 4200 and I’ve wanted to swap my mk3 ever since. Watched it too many times haha. Oh, and I vote for an unnecessarily strung out N/A motor. ALWAYS wanted to see one of these at its max without boost!

[@CC-mb8fi]

Centrifical supercharger running off of front of motor. Instant torque and boost for autocross. Ideally positioned for the intercooler. It looks like a turbo- sort of ish, and your throttle whacks off the lights would be insane. But, all your options would be sweet......

[@christophercasale7961]

Mk3s are known to be heavy cars. I think if you do an NA response build it would be more fun in something lighter. VGT turbo or Supercharger would be really cool

[@rockets4kids]

If you're planning to make 1000 HP then a couple hundred pounds doesn't mean all that much.

[@sigmaprojects]

@@rockets4kids he's referring to the thoughts of possibly doing a NA build.

[@802Garage]

Awesome! I also love box flares. I bet a lot of comments are going to say superturbo, but I vote go with the first option for now. Turbo and use what's on the car. Would love to see y'all drift this thing a little too!

[@codeycarter]

Definitely do an autocross/ hill climb build soon! Love the videos Calvin!!! Mad support

[@ronnythompson9115]

I did have an older chevy with a bad clutch. I could start it in 2nd gear. Get rolling then shift to 3rd and higher without a clutch. Only pain is you have to do that at every stop sign and light.

[@Dirtfloorfab]

Man I don't know how you guys handle so many projects

[@Calvin-Nelson]

Eh. One bite at a time.

[@Dirtfloorfab]

@Calvin-Nelson I get one "done" and I start tearing it down for more upgrades. I guess I need to learn how to be content

[@clsickspeed904]

Supercharged build sounds pretty awesome! Dont remember ever seeing an Atlas of any kind supercharged

[@Calvin-Nelson]

It's been done, but definitely pretty rare

[@zacharykelly7434]

Just the name Supracharger is worth it honestly

[@Beyondthebox11]

Love the car, I had one in high school. It was one of my favorite cars I’ve ever owned. I had the same color you have if you repaint it it will be super beautiful. That is an awesome color. I vote all motor set up.🎉

[@michaelblacktree]

What a cool project! If you go with a supercharger, a centrifugal might be a good choice, to help keep the gearbox alive.

[@Cheezeball99999]

I vote roots blower. Inline sixes are always turbocharged, and while I love the sounds thereof as much as anyone.. Roots blower! Why not? whheeEEEEEE!

[@crisisrogue8286]

supercharger!!! supercharged inline 6 sounds like a great idea! or N/A, bet they sound good revving high

[@kevrasx]

I like all of those ideas. It would be interesting to see an all out NA build 4200. But is that original turbo car the one to do that with? How would you arrange the headers on a straight 6? Six long tubes into 2 collectors? A 6-3-1, or 6-2-1 to try for more midrange torque? ITBs from motorcycle throttle bodies? This could get nasty.

[@Ironsights85]

mkiii supras are just heavy! and you have a hard top, which is the lighter version N/A or supercharged would be pretty cool! im running an ls swapped one with the factory r154 trans, which is just an older version of the ar5. 382 rwhp N/A, its plenty of fun! that lsd is reasonably strong, but i bet you anything it needs the clutches shimmed to actually work well

[@Freeloves_Whipps]

If you are worried about drivability I would do supercharger. The NA build would be sweet but will turn the car into a race track trailer queen. Love the builds✌️

[@joshbagby3784]

Man you're videos keep getting better and better I love it

[@az_3kgt714]

Guy was ready to unleash the kraken..even had the kerbal space program music playing in the background.

[@LoganC278]

Calvin im so excited with this build. After seeing the thumbnail I instantly thought of the video of this 4200 supra, funny that its the same one LOL. Excited to see how this ends up, has to be my favorite project.

[@shannonsisk]

I love the idea of a 14:1 NA build. Sounds awesome. Also looking forward to more NorthStar content. I find that very interesting 👍

[@hackjobhotrodshop5075]

Ironically I ran into an almost identical color mk3 4200 at cruise night this summer. Sometimes I think I have car project ADHD but I'm glad I can live vicariously through you on your number of projects!!

[@joshualeone4383]

Use a regular blocky type Gm map sensor for the boost gauge.

[@Christdeliverme]

Make your own sequential system using some of the E-Gates they operate quickly.

[@MegamanEXEv2]

I am so glad you saved this car Calvin! Like you, this was one of the cars that introduced me to the 4200 and I have seen that same video of it taking off 100000000 times!

[@frestkd]

NA with ITBs .. would be cool. Didn't GM build a 500hp race version for the offroad trailblazer truggy...

[@Calvin-Nelson]

That had zero similarity with the production engine. Look up Falconer Inline 6

[@Tagiau]

It would sound awesome, but for autox I feel like it would lack the low end. Be great for a high horsepower na build though.

[@buddybrozy]

@@Calvin-Nelson 500hp na sounds like a good goal to me

[@nunyaf-nbizness]

I vote with the Itb's

[@therealboofighter]

I would like to vote for ITBs.

[@cobaltlukather9045]

the most powerful naturally aspirated inline six engine ever produced for road cars was the 2005 TVR T440 R, with its 4.0L six making a claimed 434hp to the crankshaft. i'd love to see the Atlas fly past those numbers before popping on a procharger or other forced induction setup.

[@brettus9115]

It looks like a series 5 Mazda RX-7... Just whack a slightly oversized turbo on it (or tune a rising boost curve) for that old school turbo lag jet takeoff feeling.

[@drake5557]

Supracharger track car would be absolutely mental. Or do a nitrous build!

[@therowdytimes7512]

N/a balanced rotating assembly with nice induction set up for a linear curve with decent rpm. You can ways build another or change up the set up. We all love forced induction, but there is not many people on you tube pushing the boundarys or n/a and showing it to the public.

[@joeinmi8671]

So glad you picked this car up. I remember when limeswap was building it. A guy put a 4200 in a 3rd gen fbody around the same time and it think limeswap and him were friends/influenced each other.

[@dr1ver267]

I’m interested to see what the 4200 can do NA in your hands, especially with 14:1 compression!

[@seanrose3951]

Yooooo this mk3 is iconic i used to watch bro bros ig videos and it is what made me fall in love with the 42000

[@jordanharkema1495]

Ah the memories of watching this car take shape between classes. Also, 4200 auto x build has always been an idea in my head as well, glad to hear someone is making it happen!

[@716monk]

Well this is going to be fantastically useful, I've been trying to figure out this exact swap with my mk3!

[@JohnnyJackson-fi1yy]

Like that N/A build! After watching you for couple of years, goin to build one for my 50 chevy pickup.

[@TriniRogue]

Thats so wild that you got the supra, im sure i have the video of it running saved in a playlist somewhere from ages ago, this is gonna be fun to watch.

[@brucenaylor2043]

I definitely like the supercharger idea 💡

[@seanrose3951]

So excited for you to finally do a manual trans build. Id keep it simple and enjoy it as a sick hotrod. The ar5 isn't known to hold lots of power. You will pop a few! Luckily they are still dirt cheap.

[@Calvin-Nelson]

The LS guys make 700+ with AR5s. I hope we don't have issues, but time will tell.

[@RoB_666_]

Wow! A super rare, US spec only, Vortec Supra, powered by the 4.2AZ....nice score! 🤣🤣

[@Calvin-Nelson]

You funny!

[@rhecxx6941]

I’ve watched that video of this Supra 100tines since middle school it made me want something with 4200 power I was so tempted to purchase this Supra especially for the price glad you scooped it up Calvin can’t wait to see the build

[@craigfiles7067]

I'm an Aussie Ford guy, but I love watching your channel as you go out of your way to promote an underdog of a Chevy as everyone want LS or LT but you stick mainly to the 4200 , keep up the good work and get a po box so followers can send you gifts

[@aaronnoyb]

You need a turbo manual car, with an external BOV, in your life at least once. GT3076R, with a 1.06 hot side. Yes, small for a 4200, but on song from below 2000rpm, but still get to 6500rpm without excessive drive pressure. I dropped from a 3582, to the 3076, on a manual 4.5 I6, so much more fun to drive, with only barely noticeable power loss above 5500rpm.

[@michaelk617]

Procharger baby! N/A 4200's "come alive" between 3000rpm & 5000rpm. Love to see what a procharger could offer. Bet it would short track like a beast.

[@illuminatikiller1]

Love it!!! My favorite supra.......... supercharger 6-1 header side exit boomtube tack monster!

[@garymiller186]

Turbo is nice for making quick HP. But I can still remember Cotton Perry's 6 cyl. Nova. It sure sounded good! So I really would like to hear the 4200 with BIG cams!

[@GrandPitoVic]

AWESOME BROTHER!!!! I LOVE IT!!!!! ID like to see it go up against a supra!!!!

[@SupraConfused]

Very excited to see you ended up with this car! This exact car is the reason I also got into the 4200 platform and why I did this same swap lol

[@Calvin-Nelson]

I watched some of your vids last night when I was looking for the old vids of this. Cool build!

[@SupraConfused]

@ Haha thanks! Can’t wait to see where you guys go with the car!!

[@BlakeEM]

My first car was a 1986.5 mkIII Toyota Supra. I went through an engine, head gaskets, and a transmission. It's a decent handling car and it surprises me how cheap they still are. Mine had 17 inch 5zigen fn01r-c wheels. I think 17 inch look best on this car (not a fan of the 18s on this car). Mine was slammed on Bilsteins with 10.5 inch wide in back and 8.5 inch wide in front. I'm very excited for this build.

[@Yan1nc]

a 350whp+ N/A straight 6 Supra would be cool

[@Emilthehun]

It would be really cool to build all motor hp . Itbs , some cool headers , cams , high compression. Im loving it!!!! Lets do it!

[@TaylorMadejdm1975]

Noice! The Infiniti wheels actually look damn good! 🍺

[@DrewLSsix]

Back when the gen5 wasn't even a concept car i talked about the I6 being ideal as a base performance motor for a new F body. I got a lot of push back from people, but the most absurd was the idea that 4.2L is just somehow too big for an I6. The thought was that the 2JZ was a 3 liter, the RB26 a 2.6L, so thats obviously the correct size for an I6. Besides the fact that if GM wanted to, they could easily produce a 3L version of the Atlas, the only things they could come up with were some vague notions of bore stroke ratios, ideal combustion chamber width etc.

[@Dirtyz1234]

I like calling my turbo BMW E46 the gentleman's Skyline GTS-T to get the JDM fanboys a little heated 😂

[@Mis73rRand0m]

I have an XI, does that make it a GT-R?

[@NeverEnoughRally]

The rear diff is a Toyota 8", similar to what was in the trucks. You can swap gear sets meant for trucks into these with the right combination of side bearings.

[@Jared45513]

Oh yeah, love it man! And thats coming from a pretty big toyota/supra fan. I have an ebay knock off and an oem toyota ct26 dual inlet turbo, downpipe, and manifold I would give you if you decide to go that direction. They ran good, spooled fast on the 5sfe. Lag was minimal to none as long as you didnt dog it. There sitting on my shelf, we can email if your wantin them.

[@xozindustries7451]

Wow, I’m surprised how heavy that thing is, cool project. I vote roots or screw supercharger, it will be cool to have a auto cross / road course car

[@froopty1854]

I think this would be an excellent time attack car, really show the capability of the 4200 in circuit conditions, also a 4200 with individual throttle bodies would be absolutely wild to hear

[@petervanhorn6543]

I think NA or supercharged would be different, just discovered your channel and I am absolutely hooked on 4200s

[@sijonda]

Despite the paint, that thing looks really clean. For relevance I live in the rust belt.

[@Calvin-Nelson]

Yeah. It's got a few bad spots, but everything structural is good to go.

[@stevenreid-g2y]

Would like to see a well-sized turbo to make @500-600 awhp. Let's face it, we live in the era of the turbocharger and I'm all for it!

[@JamesJames-r8t]

But he could make that na 😢😢 Why you Want to make such little power when you use force induction😢😢😢😢😢😢😢😢😢😢😢 bruh at least 800 or more with forced induction 😢😢😢

[@seanrose3951]

Right, your english sucks worse then your comprehension of vehicles.

[@DANOBILL]

I think it’s about time someone does a Baja style engine build. Maybe bore it out and/ or build it to rev high. That or the supercharger would be cool. We want to see something with an unobstructed exhaust!

[@jayburrough4308]

For sure turbo for this car

[@tylerdiaz906]

N/A build with ITB’s!!!

[@paulhoogeveen7353]

Barra powered Mustang!!!

[@kyletice811]

I vote custom m122 supercharger setup. All the torque. Instantly snd some nice whine.

[@ethanschocke333]

its actually ironic the ar5 is a common JZ swap trans. its basically an R154 supra trans but for murica.

[@Greaseland]

Welcome to the world of going around turns.

[@4BillC]

MK3's are very under appreciated and personally I'd rather have the MK3 because of that. MK4 draws too much attention. I supercharger would be sick, but NA hp is usually better. This coming from a guy that is pushing 25psi (really small turbo) just to make 300whp with a little 1.8. End goal is 400ish I just need to put the bigger turbo on and finish the exhaust. The car only weighs 3280lbs with me in it and is a daily so I don't want to go crazy. I wish I could make that power NA! But I get 20mpg on pump E85 so I can't complain really...

[@tlovsoe4211]

I think na sounds best. however it would be cool to do a fast spooling turbo car using a swirl throttle.

[@joesf1026]

Supracharger ftw

[@randoawesomemix9501]

Yes! 3rd is my favorite generation of Supra.

[@s7v7nfiv5]

Now thats what am talking about Love those supras theres plenty of parts available in the market and even 1 of them recently made it in the word final.

[@Audi30V]

Turbocharging would be fitting for the car, but 300+ NA hp would be great for autocross and would be excellent content since it’s a different avenue from your usual 4200 builds. That gets my vote.

[@Rocksolidbullys]

Let's show them 2jz boys that gm can make a wicked inline 6 engine just as well..! The camaro and Supra are going to skyrocket your channel!!! I am very excited to see what you can do with these.🔥👌

[@dannyjr7997]

NA POWER would be great! Should hit around 280hp with higher compression and intake easily. These 4200 breath so good.

[@Calvin-Nelson]

Yeah. They make 291 at the crank from GM, so 300+ wheel should be easy

[@estebanmatias92]

Supracharger or NA, both sound great.

[@GIGABACHI]

Go N/A but keep it pump gas friendly . . . If at all possible. Good luck, I'll be watching. 😎👍

[@BuildaMan]

I am all for making this an autocross car or something along the lines of having to turn and i am also for the idea of doing a balls to the walls NA build just to see what it can do in that respect and to hear how it would sound.

[@2dogsmowing]

The mid to late 80s Honda Accord is resembles the supra alot. 🤔

[@PiDsPagePrototypes]

Clutched Supercharger that feeds Intercooler until Turbocharger has spooled up, so it's never off boost. But keep the boost limited and let it rev, making it fun on twisty mountain roads rather than a drag car.

[@hopingforthebest1.9]

I would be curious to see how much power you could squeeze out of it all motor Maybe with some kind of ITB setup as well?

[@McDoubleNopick1es]

Someone in a reply said compund and i agree, a small one for low end spool that feeds into a big boy for the top end.

[@OriginalTypeQ]

I think if you are building an auto-cross car, build the engine option you can get running reliably in the least time. Then focus on improving your driving skills and fine tuning the suspension.

[@leveluplife8585]

Torqueamp style supercharger would be a cool build and relatively simple compared to turbos

[@fuse8052]

I love the idea of the mega high compression NA engine. I like the supercharger idea more , but I also do autocross. NA cars I feel are more at home there
