Installing an EBAY TURBO on our Gm 4200 Vortec! Budget American Barra? 

Mate I’m really impressed with this project so far, it’s great to see someone learning on a different motor something other than a LS or 2J which have been done to death.

I think the Atlas engine is an undiscovered gem!

The 4L60E as we all know has, P R N N Good luck!

I'm definitely stoked for this! As a BMW guy, I'm always stoked for I6 content (little tired of JZ stuff in general though).

it gonna look like those nissan patrol's from the middle east with huge turbo sticking out of the engine bay that's a rad project hope it success

Hey guys, don't forget about the 5-cyl vortec! Sounds awesome too and slightly smaller form factor 👍😎

06+ for the piston rod oil squirters

I previously had this on my trailblazer! Gave me no issues lasted me 450k plus km and now I want one to build and slap on a e46 to drift. Glad I came across this vid

This thing literally sounds like a bigger jz. So sick

This is sick. I am really excited to see how it runs on ecu masters.

Could be a pretty cool idea to try to swap it into the s14 to test this swap since its already a rolling shell and you know the chassis well. Then you could try to drift it and swap it in another car and do the k24 s14 ! Could be a fun idea in my opinion ! :) keep up with amazing content ! We love it!

Take a drink every time he says “basically”

I love this! Great idea to use it as a learning platform for tuning a new build from scratch. Really can't wait to see this rip.

The 2005 Colorado 3.7 is the exact same engine with a cylinder chopped off. Has a turbo kit readily available. Add another pipe to the manifold and you're done. I just found this info days ago

The 80’s montage music has returned!!!

The Atlas engine have a lot of potential, too bad they were so short lived.

I’m very interested in this, my Colorado has the 3.5 inline 5 which is basically your engine with a cylinder chopped off. Been wanting to tickle it with some boost for years now

😏 i have 06 trailblazer and i want see more never done some serious mods to a car but you got me thinking about it. Oh fyi right behind the the cap isn't that where you can put the drain

Trev (and anyone else). RFHs Tech tip for the day. WBO2 sensors need to go POST turbine and be atleast a foot before the exhaust pipe exit. They are pressure sensitive and the high exh manifold pressure will cause them to read wrong. they need to see near ambient pressure and if they are too close to exhaust pipe outlet they can also see some erroneous O2 from flow reversion of the ambient air going back in the exhaust. Also mount them at an angle so water doesnt condense on them and short out the heater.

Don’t be silly and throw that in a fox.... hurt everyone and put it in a Supra

I have an 03 Trailblazer LS with this 4.2l inline 6. Have had it about a year and it's really smooth an you can tell it's pretty strong, would love to see more done with these engines. Good vid, you got a new sub out of this. Awesome job, man...

This is actually helping me. I have a '06 and I've looking on how to do it. Thanks!!!

I’m excited about this! I have an 04 trailblazer that I have been wanting to do this on but was trying to figure out tuning without going stand-alone. I watch all your vids but I’m for sure gonna enjoy this series! Plus now that we have a stay at home order in fl I have a couple weeks to get it done!

I had my doubts but I now see the vision. Really interesting to see more about the engine performance. Great job Trevor

Great work.... I'm doing a 3turbo set with same engine... The Vvt is what I'm looking forward to....

I would like to see you try and get the 3bar map sensor to work because it would be something normal people could do. Thus it would be more repeatable

If you have a scan tool that can do a throttle body relearn on it you can get the rpm to about 6k but only while you’re doin the relearn. Helps to hear it rev higher.

Man I had an 05 trailblazer with the vortec 4200. I had a k&n intake and Gibson exhaust and lift kit. That 4200 just has always had such a sweet tone, the turbo makes it even better!

Like you said at least you could use it as a learning experience. If it works then that’s a bonus to people who want to possibly build one and put it in something.

I've got a hell of an eye on this. A relatively modern inline six with real potential? In *North America?* That's like opening your window in the morning and finding Scarlett Johansson dancing naked outside your window.

Hell yea, just got in there and got it done!

for me the ideal project for this engine is an f-body camaro especially for the guys who has the v6 and want to upgrade to something cool. Of course if and only if it works. keep em coming

Totally cool, something different from the normal stuff that we see all the time...

You can weld the cast steel exhaust manifold. Pull turbo in tight and drop it to get stock look of hood with no bumps or cut outs . Sleeper style. Turbo drain goes into the oil pan outer wall where head drainback oil passes the crank to enter the pan at bottom. It has an inner wall windage "wall" Aluminum oil pans can be tig welded to put in a bung with threads

The explanation sounded exactly like what you did to the mustang sick seeing you do stuff kinda outside the box and crazy. Just don’t give up on it like the LS Sab

I’ve been wanting to experiment with my engine the same 4.2L vortec in my 07’ trailblazer LT 2wd -but I’ve been encouraged by everybody I kno to LS Swap and trans (4L80…) and if I’m willing to do all of tht just sell my LT and get a TbSS

Lowered Turbo 4200 Trailblazer, man that would be cool. I've always kinda liked how the Trailblazers look, especially lowered.

YES!!! This series is going to help me with the build in the future thankssss!

I daily drive one of these but a 02 SLT model. I’m the second owner got it clean as hell. I want to do this bad 👍🏻

Budget Mad Dad Exo-Truck Huge amount of cage-ness. Safety seating for family. Helmets too. Budget Family Trophy Truck with different wheel loadouts. A set for rock/hill climbing in the off-road tracks and in the mountain trails. Driving where you had driven that SUV. Another set for the sand-dunes, and another set for Snow/Ice tires. Try to find the 4x4 transaxle/transmission, and the axles/hubs. See if you can fit something like OEM Chevy/GMC brakes that are sportier, maybe used/good Corvette brake calipers/rotors/pads for it. Maybe the Trailblazer SS brakes? Maybe the Trailblazer SS's 4x4 drivetrain?

I have a 05 envoy been wanting to do this for the pass year can’t wait for the finish

506K Subs. That is an awesome milestone. Keep up the good work. You guys are such a great team.

Im stoked your doing this. I'm planning on swapping an ameraberra into my 72 c-10.

I enjoyed watching the episode where the guys on Roadkill garage built this engine and threw it on the dyno. Stoked to see you giving this a go!

That engine sounds rad actually

when you return the oil to the valve cover or oil cap you should run an extra quart of oil.. my buddy starved his small block doing that because it wasnt getting back to the pan fast enough on pulls.

Keep it on that frame and make it an Exoskeleton kinda truck.

Why would they use alpha-n? That is designed specifically for use in independent throttle body applications. It should be tuned on speed density and you should be able to access that and switch it over if it isn't using HP tuners.

i want to see a fully striped fox body drift car with this engine in it! excited to see where this goes.

I think this is sick. at first i wasnt sure but its really interesting to see and engine outside of the standard stuff thats on youtube.

this what i drive and i never thought i’d hear one with a turbo

I have an ‘05 Envoy and have always wanted to see someone do something with the motor. Put the pedal down and they sound nasty! Keep up the great work!

That engine would be perfect canidate to put into an ole square body. Since they used to come with them and there would be plenty of room.

I love how your videos are different and outside the box. Can't wait to see it make power

Those manifolds are notorious for cracking

Keep it going! Looking forward to seeing what it makes before it blows up.

I have an 04 xl with 247,000 ish miles and still going strong

So Whts the verdict… how did tht 4200 fair? Dyno? 1/4 mile? Top speed? Long term review? Part 2? Any Follow up’s?

My first car was a gmc envoy and my dream was to turbo it I’m so happy to see this 😂😂😂😂

Why am I so excited about this build lol. I like seeing vehicles nobody turbos to see what happens thats why!

Where did you find this turbo? I have a 2002 GMC Envoy 4.2L and im trying to make mine a sleeper

I have an 03’ Isuzu Ascender with a 5.3L V8 and I’ve always wanted to see a turbo build on it.

I’m taking notes. I have an 08 envoy with that engine. 👍🏼👍🏼

It’s gonna be sweet another build I been waiting on

Thing sounds awesome, just like those sandhill climbers in the middle east. Heavier than a regular 2JZ but still it's lot alike. This engine could be a undiscoverd great platform like the Barra. Supercool to see you just jump into the rabbithole and go venture. Awesome content.

Do you have a link for that turbo kit or can you recommend any? But great video

Dude, you going where thousands of Atlas lovers have wanted to go. It's a great platform to exploit and see what it's true potential is. There are basically zero aftermarket mods for the 4.2. and people are craving them! Vids like this could spark some manufacturers to get into the game and see that this platform is worth producing parts for.

I needed this. with all thats going on in the world, this is by far amazing and cool.

Turn the project truck to a 4 passenger death kart. That be amazingly fun and super cool to see.

I would love to see that 4200 in a old square body, or maybe a nova 2

Now THIS is the video I need for a rough day. :D Freedom 500 tonight everyone? Hell yeah brother!

Trevor's making me want to turbo my 04 trailblazer now lol can't want to see how it turns out

I think the term about using cheap parts to see if it works before buying good components is for R & D purposes only ;-) lol

Killing it with the time-lapse tunes!

Sloppy mechanics tuned an atlas swapped studebaker on their channel. It'd be cool to see how far you can lean on one of these in factory form with a good tune.

Im def excited to see what this thing is capable of. Maybe you can find the few weaknesses and how to solve them.

I think this thing sounds pretty decent I'd be curious to see what this can make before it shoots a rod out.

the one thing that kept me from buying a 4.2 Envoy was the lack of aftermarket support and the death of the engine. Found a 5.3 XL instead sadly

My 2004 cracked the exhaust manifold twice, you are probably loosing a lot of boost out of there right? Cool idea, I always wanted to turbo mine, it was 2 WD with a locker diff, pretty quick for a SUV like that

love the channel man, have a chat with Fasterproms im sure he was talking about GMs have something in the tune to change the rev curve (throttle response) because GM set it up for daily driving im sure you can change it to rev quicker(start of pfi speeds video with the corvette and Fasterproms)

What kept the Atlas engines from aftermarket support was over engineered timing chains in the front and rear of the engine.

i dont know why, but the idea of it going in the crown vic with the manual swap sounds cool

I saw that motor trend did something with one of these but the pay off episode is behind the paywall, I'm genuinely looking forward to what comes of this. Always had a soft spot for an I6

This is the type of content that will drawer people in. If it's a cheaper, more readily availble platform and you can make some power with it, win win. Plus, if people don't want to sub to MotorTrend just to get their take on this, you will get that traffic as well.

Great engineering bro

I've been dying to see someone do this after I saw that motor trend teaser. Might be a cool swap for my S10. Guess I'll find out after this series 🍻

Half a mill subs👏👏👏🎂

I love this new build, hope this engine proves to be worthy! When I had one it got worse gas mileage than my hd 6.0 and had less power than my 4 banger lol

People need to know that you need to combine parts from the older 02-05 and the newer parts from the 06 4.2l and you can make more power.

Helllll yeahhhh brooother!!! All the boost

No videos other than the install?

That thing sounds incredible holy hell

I'm looking forward to more content on this!!

One thing I learned when I had my 4.2 was the stock coils won’t handle a lot of boost. You’ll have to switch to Ls coils. I also know a guy on here that turboed his 4.2 I can send to you

This feels more like what you build than the Audi.

What about just flipping the exhaust manifold over? Let it swoop forward instead and slap a v band on.

This will be interesting to see where the Ameribarra ends up. 👍

At first I didn't care until I heard it run, damn Trev this will be a super cool powerplant for something. Throw this in the 240!!

Hey I have a 2002 Chevy trailblazer 4.2 L6 vortec same exact motor like the GMC Envoy trying to get a little more power without major upgrades.

16:27 oil cap magically appears XD
