WHICH IS THE BEST (LOW BUCK) JUNKYARD TURBO COMBO (5.3L vs 6.0L) WHICH ONE IS BEST FOR BOOST? 

Richard i feel like i have to start paying you tuition. Great videos dude.

I’d go with the 6.0 simply because I have one and it was free. Just gotta wait for my wife’s 2008 conversion van to rust off of it. LOL.

It’s not a 5.3 vs 6.0 question (I think) for most people. It’s a 4L60 vs 4L80 question. It’s almost easier to pick up a 6.0, boost it, and not worry about blowing up the trans.

Set up a patreon account so we can pay to see you throw a rod on a 4.8, 5.3 and 6.0 would be curious to see how much boost each could take before it blows. And see which comes out on top HP wise!

Ruby's 5.3 finally gave up the ghost but only because of the heads. Swap out the head studs and I'd put money she wouldn't have needed Leroy's old 427. If you're confused, you obviously don't Do it for Dale. Hell yeah Brother!

With 600+hp most ppl will put it the ditch.

Well, you're familiar with my thoughts. I have 6.0's because I'm paying the same price for them, but otherwise, if it spins, it wins. For power levels that will make the average person poop on the street, it really doesn't matter. Get a complete one that spins and roll. I do agree equal or greater power with less boost is always better. I would rather see a guy doing burnouts with the 5.3 he can get today than saving up for a 6.0 tomorrow, then wind up punting the whole thing on marketplace and never doing a burnout.

My plan is still the 6.0 with boost. I believe the higher power number is going to give me a better end number with less boost. Hopefully it will be a little more reliable because of it. I want the ability to turn it all the way and not have to worry about having it come apart on me.

As much as I like the 6.0, I definitely agree with you that the 5.3, in the daily driven application, would really be the best. Great video thank you for creating it!

I love the argument with yourself. That was awesome!

Thank you ! you start to change my mind because I was stick on 6.0 ! I like all of your test!

I look forward to your videos Richard! So very detailed and informative, keep up the great work Sir

I've never found a channel so informative with real world testing. You got a sub and a like and I'll share your channel to everyone I know

This is by far the best testing and trying different combinations I’ve seen.This is for guys that really understand how to make power and torque from an Ls.and great for beginners.I have watch them all!!5.3 street turbo set ups are my favorites 700 hp on 13 psi is crazy !!!keep the tests coming!!!!!!

Enjoyed the opening skit. Love watching your stuff. Very informative content.

Thanks for the education brother. I really enjoyed the show.

THIS CHANNEL IS JUST FOR ME PERFECT.

Absolutely love the videos and amount of information you share. One question I have(and I don't think you've really covered it) is engine management. I'm building a TT 5.3/4L80E daily and I'm looking heavily at using the Holley Terminator X Max setup. Do you have any thoughts on it?

Thanks for the comparison! like someone said earlier the 6.0 graphs are missing, still great info!!

I have learned so much from this guy by just watching 3 videos. So glad I found this guys channel before hoping into a project

The best caricature of the internet ever. Good job man, and very entertaining, and I've learned a lot. I owe you some beers.

Love your videos man your truly amazing and all your knowledge helps millions for sure... 5.3 cam springs and Rods stock ring gap how much boost before bad news

One of my favorite youtubers learned alot from you greetings from dubai 👋

Man... i have watched you vids for a few mnths now, and it just hit me that i have never soaked up so much info on the topics! Good stuff boss!!!! Just liked,sub'd and...hit the bell!🔔

Very informative. Im building a drag car and been kicking around the idea of LS turbo. This has helped a lot. If you have any build specs for a 6.0 that makes 1200+hp it would be greatly appreciated thank you

I have a modified Mitsubishi Starion and I’m leaning towards the 6.0 because I’m going to hold on to the car for a longer time, and is lower and lighter from what I’ve been told. As I go towards boost and I think making more power at less boost will lead to me not having to worry about breaking stuff right off the bat and therefore losing money replacing stuff because I’m trying to roll with the higher boost levels.

I say let's do it.. ive learned so much from this channel so glad you do this ... keep up great work.

Love this guys videos man good stuff 👍🏽

To replacement for displacement, but I'd be happy with a 4.8 or 5.3, I'm looking for power and mileage, a stock 4.8 with 10 psi, maybe a cam, would be fine, the little engine that CAN!

Looks like the graphs where missing from the second half of the video right when you were talking about the 6.0. But once again great video! Appreciate the theory in action that you explain. Keep up the great work. I look forward to the daily videos. One thing I am curious about, mind you I haven't spent any time researching this on my own, is the effects of larger max out put single turbos vs drivability. Ie running s480 or s485 vs smaller turbos will drivability suffer? Will power only come in after 4000 Rpm or can that all be adjusted using proper boost controller and tune? Pretty open ended but it is something I have been curious about. Thank you.

Lmao ! I am hooked on this videos thanks Richard your videos are really informative keep them going! Stay safe

Love the channel, very informative

I have a GEN 46 L 823 heads and plan on running it with low boost for engine longevity but a higher horsepower rating. Your videos have been so informational to me and have really directed me on where to go with what I want on a budget

Like o-ringing on steroids. This is the current system used in Top Fuel. One piece SS hoops that press into machined grooves in the heads approximately .065" deep with receiver groove in the block that the copper gasket gets swedged into. Cylinder pressure has to make it thru four 90* turns to.

Thank you Richard

Dag man....new to your channel, but a ton of awesome info here, great work. Thanks for sharing your thoughts and work....

As someone who actually owns a turbo LS in a street truck, you need a lot of chassis/tire for 600hp. I have a 5.3 and 7875 and have considered the 6.0 but I think the extra power down low will just make my non-existent traction worse. I run my setup at 10psi most days because it's easy on my high mileage 5.3 and the truck is still insanely fast.

I've seen you say in multiple videos.... "well if I rerun the big bang I'd do...." with all the info you've gathered I think it's time to do it again. I'd love to watch some more 4.8l stuff too.

Really appreciate the videos. Informative and catchy. Lol. Thanks brotha

i rewatch these videos weekly thank you Richard i learn so much from these. God bless

Honestly, if I were looking at a budget build, there is more to consider then just the engine. If you run a turbo 4.8 you will get tons of power but less low end torque so you don't have to run a $3000 transmission and your modified stock suspension might survive. I think the biggest mistake people make is trying to go fast in a heavy car, a 3500 pound car will get it's butt handed to it by a 2500 pound car. A light car saves money everywhere.

I can tell you from a heavy truck point of view it’s hard to beat the 6.0 and 6.2. I was a 5.3 guy for years and years and one day my timing gear broke which took out the motor. I got a 6l at a really good deal and wow what a difference. It was so much nicer to drive out of boost. I was on leave in arkansas when it happened and I had towed my toy behind the tahoe. On the way back home with the 6l I didn’t spoil the turbo near as much just because the 6l had so much more torque to pull hills I didn’t need the boost like the 5.3 did. If all you are doing is racing then MAYBE it doesn’t mater as much. But for daily driving in a heavy 6000lb truck the 6 and 6.2 is WAY better. It has a 6.2 now and a much bigger turbo cause the single tc78 was a tad small on the hot side for the 6.2.

Awesome video. I'm looking to do a swap fairly soon and this definitely helped me out!

Another great video, I have a 98mm for my 6.0 and again I’m a novice on these LS engine but I’m learning as I go 🤘🏽 thanks for the video Uncle Richard 💪🏽

For all out power the old saying always rings true. There's no replacement for displacement

I'd chose the 6.0, I like more power with less boost. Better for a daily application

Someday, a max effort LSA shortblock (steel crank, beefy rods, and hypereutectic pistons) would be very interesting. Thank you for your efforts......Mad Respect

I really like your new platform. Keep it up, and you will hit 100k subs real quick. I am really stuck between a prc headed iron ls1 build with a summit stage 2 or 3 cam, 8607 or the next largest or just a VS denmah kit. I want a fun truck, but really don't need a bagillion hp. 1000 for VS kit is cheaper than the prc heads, but still will require more fab and cost.

Richard here in Australia we dont have 4.8 or 5.3s so I used a 6.0 as they're readily available but i wanted a physicaly small turbo so used a 7875. We need to be wary of high backpressure now so in this case smaller cubes would probably be a better choice

If cost is not the issue I would go for the 6.0. My friend held numerous NHRA world records and his motto was ( There is no replacement for cubic displacement ) His records were with N/A BBC’s.

hell yeah richard you the man

Great stuff as usual

Very informative video! I think I prefer a 6.0

I have a 6.0 in a gbody with a gt45 wrapping up the build now. I’ll be happy with 600hp Thanks for sharing. 👍

Love this content. Numbers don’t lie!

Thank you. Good video gear info

It would be neat to see a test with a 4.8 vs a 6.0, with a 7875 turbo or similar. And see where the turbo caps out for each motor. If that makes sense. I know the bigger motor will cap out sooner all else the same

If you go down the road of cam,springs etc on 5.3 to get NA power up to 6.0 you probably wouldn't have much more dollars in it to start with 6.0L but have a better foundation for future upgrades as no one is ever happy with what hp they have for long, right ?

Keep em coming lad !!! Don’t sell out like others have when their Chanel gets sponsorship

You deserve more love brotha 💯 hope your channel continues to grow and never stop!

I agree with choosing the 5.3 for most applications. But if you’re going max effort, just having the bigger bore on the 6L opens up options for head selections not available to the 5.3.

All things being equal relatively speaking, the 6.0 will always flow more air and thus will always have higher peak potential.

I always think no replacement for displacement. I agree with you Richard. Now what if I put a better rod in the rotating assembly only ? Then how much boost could she take and what would break next? That would be another story!😎👍

I want to thank u. I just subscribe to your Channel. After watching 3 videos and everyone of them with dyno test . Leaving out any questions . I'm an old motor head. Because of my son. Getting me back into it. Now It's all about the LS . We are building a 5.3 & 6.0 . Thank u for making this easy . With less trial and error like the old school ways

The Richard vs. Richard argument was hilarious. For My money, the engine I choose would be based on the big picture of the build, the vehicle's mass AND it's intended use.. In a true street car that's heavy, the area under the curve is where it's at. For a light weight drag car with tons of turbo and converter, I think it matters less. And ultimately, the bigger engine is gonna make more power everywhere.

Thanks!, great info. Many variables to consider depending on your goals. I went with a 5.3L ~10psi im happy, wasn't going for record breaking power levels. Just a reliable fun car.

MIND BLOWN

Awesome vids thanks for information

Hey Richard- you forgot to put up the dyno charts in the 2nd half of the video. You're killing us smalls! You have the data, but this time you left us hanging... :)

i want to see the eaton v6 supercharger make some boost on that V8 ! that looks like something i'm willing to do on my 5.3 !

Awesome videos!! 🔥🔥🔥

I'm definitely going for the extra cubes every time,

6.0 is the end all be all for me ! Because that’s what I got !

would really love to see you push a gen4 5.3 or 6.0 with the vs racing 94mm and methanol or twin 7875s to it's limits

I was really looking forward to this video when I saw the title. I would’ve liked to seen the Dyno numbers side-by-side ...

There are 6.0’s all over the yards here in Maryland! Not as plentiful as 5.3’s, but they’re definitely available. Every once in a while you’ll find a gen 4 motor, but people normally snatch them up as soon as the truck gets to the yard. I’m ALL GOOD with the Gen iii baby! They’re rock solid motors

I like the 6.0 that is what I am putting in the GS. Sounds better and more power at less boost

Great video very informative Would like to see lsx 427 vs.454 vs 468 n/a and turbo. Love the videos

Thanks for shearing your wisdom your awesome bro

57 seconds in and I gave it a like!

I think the problem is there’s a lot of builds that aren’t built correctly and the engines are catastrophically failing and people are hypothesizing that the cylinder walls distorted and running with that narrative.

If you got the money then obviously a 6.0 is the way to go. But for the average guy that just wants to make his car faster and more reliable ANY good LS based engine is great.

You are having a lot of fun with this aren’t you 🤘

Richard I love your videos. Brother you are such a great help. If I don't have a wiring harness what do you suggest. Thanks

Would love to see a big bang test on an aluminum 5.3 like an lm4 or l33.

For me it’s about goals, I am into cars for ice cream and burnouts. My gen4 4.8 76/65 does everything I want it to do and no one wants a 4.8.

I’m glad I found your show, as my dad and my brother are both having issues with both of their trucks. One is a 2011 5.3, the other is a 2002 6.0. Have you considered doing something with mopar’s 383 vs 360?

EXCELLENT VIDEO!!!!!!!!!

The 6.0 also with having the 4.00" bore, you are open to utilize rectangle port heads (LS3/L92/LY6). Bigger valves are nice to have that option on the table.

Oh my goodness I was actually laughing quite good at "one of the bros told us." This took the words right out of my mouth. "bro your engine is rusty"

I bought a Gen IV 6.0. Rec port 823 heads which I ported and polished. VVT cam which adds a little down low and up top but sized for a good combo of torque and HP (218/230). We will see how it runs.

Can you do a video like this on a 5.7 vortec? Very helpful and looking forward to watching more of your videos!

I think when talking head gaskets deck thickness is more important than cylinder walls

Can you do a forced induction comparison? Same engine at the same boost levels. Turbo, centrifugal, screw and positive displacement. I think a lot of people would be interested to see the overall power levels and what the actual curves looked like.

I think the three biggest things are 1.) daily means daily driven which means daily repair so parts available and cost 2.) gas mileage 3.)can it blow the tires off at any point if I’m just cruising to work if all three of these are checked then run with it I currently am doing sbe 5.3l with a Garrett turbo off my 02 7.3l diesel in my 94 ext. cab step side

Great video!! I have a 08 5.3, torqstorm, all stock block, upgraded aeromotive 340 fuel pump and 80lb injectors. At times I'd have to bled my fuel rail to start my truck. Idk what's causing this.

I'd be hard pressed to replace my 6.0 with a 5.3 regardless. Now, if I had a vehicle with a 5.3, I would not spend a ton of cash going to 6.0 if I planned to boost it. Just my thoughts.

Split screen scene had me thinking I was watching a multimillion dollar budgeted, Hollywood cast, Grammy nominated movie.

I'm currently running a Gen 3, 5.3 in a '68 C10 with a 700r4. I used a few durability parts like a new oil pump, LS2 timing chain and bushed the rocker arms with new one piece pushrods. Go fast parts, BTR Stage 3 cam, Fitech Ultimate LS Induction w/ 95mm throttle body and long tubes. The long block is stock down to the 706 heads and it's quite lively in that truck running very low 12's. I got the motor for $500 and sold the harness, water pump and misc. parts for $300. The motor had 41,000 miles on it, there are plenty of them around for that price. I've only seen 1 6.0L for sale in 3 years around here out of a wreck with 131,000 mi. and the yard wanted $1500 for it. The choice is simple and if you want to pressurize it who's going to know the difference between 1200 and 1500 hp on the street and could you really put it down on the track with a street vehicle ? The engine in my little truck most likely makes just shy of 440hp and on full tilt can be a handful. I might turbo it in the future, keep it mild at or just under 2 atmospheres and enjoy the sound and occasional kick in the butt into the 11's but for the extra cost of the 6.0L I don't think it's worth it besides, I bought a Gen 4 5.7 rotating assembly for penny's from a local machine shop, I just might have to get the boring bar out.

I chose an na 6.0, I rebuilt it and put forged steel rods in it. I was only shooting for 500hp but something that can be beat on day in and out and it will love.
