JUNKYARD 5.3L L83 NITROUS TEST-THE REAL DIRECT INJECTION!

FULL NITROUS RESULTS! Junkyard 5.3L L83 (Direct Injection LT motor). How well does the new 5.3L compare to the previous (LS-based) 5.3L or even the larger 6.0L? Does the Direct injection and Variable Cam Timing (VVT) really add power? Do the new motors respond to performance modifications like headers and air intakes? How about a quick shot of nitrous?

[@RadDadisRad]

This L83 stuff is riveting. The thing out does a lot of other motors.

[@petejoseph8257]

L83 looking more boost able than previous aluminum 5.3s. Bigger 12mm head bolts vs. 11mm, piston oil squirters, bigger oil pump.

As for fixing fueling. In Australia we run staged injection when modifying GDI engines. Keep the OEM di, and stage in port injection. Just like toyota/Subaru do in the 86/BRZ. Also keeps the intake valves clean as well as the di injectors cool. Probably can't do it with holley efi🙄😅.

[@pauldejohn8710]

We are doing the same thing here with the EcoBoost engine's

[@BEANS-O-MATICtransmissions]

This is already being done and there are kits developed with a holley ecu and port injectors for our genV V8

[@RadDadisRad]

Ecoboosts don’t like to see added fuel tables, the fueling loop likes to pull fuel and force the port injectors to work more or it’ll just cut power. I’m working through this issue with a gen 1 ecoboost.

[@pauldejohn8710]

@@RadDadisRad have you had any luck with the DW injectors with xdi-60 pump

[@RyTrapp0]

Being able to run big power through only direct injection is the 'holy grail' though - you can get much more aggressive with the engine build & tuning since the window for detonation is SIGNIFICANTLY shorter because obviously you only add the fuel into the cylinder when you want rather than as soon as the intake valve opens

[@SP33D3M0N03]

I've been tuning on a 2014 l83 5.3 and I messed around with the cam timing, I've also found that fixing the injector timing table also helps, or seems to help according to data logs. Very cool to see you doing this! Excited to see all the results!

Hey richard in your very first clip on this video. When you did the na test looks like the nx system was leaking. You can see fuel coming out of the nozzle and when the throttle blade closes there is frost on it just like the 100 shot pull. Do you thing the nitrous was leaking and that's why it was such a high na numne.

that was just residual fuel from a previous nitrous hit-the na run didn't actually have the nozzle in place.

[@patlandymore7035]

I absolutely enjoy each video you post Richard. My thoughts on the LT testing follow along the path of another suggestion....but move the L83 to 100% port injection. Just remove the DI pump and leave the injectors as blocking plugs.The LT already has a 58X timing set so the Holley would easily work, other than VVT. Also interesting would be to compare power output with a DI/port injected mix, with pure port to see the difference. Would learn a lot about the differences in the head design between LS and LT engines that way.

[@dronedadfpv4541]

It would have been interesting to see the manifolds with the stock catted Y pipe vs the headers. I’d think the converters would be the main restriction there. It would be neat to see the stock air inlet vs a typical cai also. I’d love to see more ltx dyno testing!

[@HGHG-sd4ht]

Thanks Richard, as usual a very nice and informative presentation . I was thinking a closer comparison of LS base to LT base would have been comparing Gen IV LC9 to Gen V L83 since they are both 5.3 and both equipped with VVT. You could then have a fair idea on how much the Direct Injection + Higher Compression ratio + heads design + twisted valves would contribute to that power increase. Just an idea. Thanks again for the effort you go through. A fan from oversea :-)

[@goodmanboattransport3441]

Way back when I turbocharged my 1.6 Suzuki, the tbi wouldn't flow enough fuel, so I built a megasquirt and grafted on 4 port injectors that would handle the boost chores kicking in at 1psi all the way to 10 psi, I got around 150 hp out of the little motor, so if you added a e85 aux injection system you should be able to get all the fuel you need

Swap in the l86 intake manifold and throttle body. The stock heads could use a lot of opening on the exhaust runners to match a 1-7/8” header primary. Even the stock exhaust manifold ports are much larger than the exhaust outlet of the cylinder head.

Were you successful? I wanna do this same build swapped in my 85 trans am. Looking at the tremec t56 magnum F, made for F body's. I'm aware the l83 is not made to fit any standard trans without specialty work done. Was wondering if you have any tips or pointers on what is required to make it work. The magnum F is different in length than the standard t56 if I'm remembering correctly tho. Either way any info would be great, I've scoured forum after forum and it seems this particular setup is rare, not much I could gather about it.

[@cfltitan]

I LOVE the L83 in my 2014 Silverado. I have the airaid mit tube, modded airbox with an aem dryflow filter, muffler delete, tune and E85 and this thing rips! I smoke 14+ rams, tundras and even the older gen ecoboosts. The really cool thing about the flex fuel L83's is that even in the factory ECU they change from 355hp/383tq to 385/416 with just E85! They're fucking beasts on ole corn juice! Also for the headers I think what may be wrong is the smallish factory throttle body and intake. Swap that out with a L86 (6.2) intake manifold and throttle body or even better a ported TB or LT1 TB. They flow a LOT more air in and generally make some pretty good numbers even on a fairly stock L83.

VERY cool stuff. it's amazing how much more power can be created from the same displacement....... it would be REALLY COOL to see the same back to back with a cam only swap on both mills...... maybe first using two camshafts as close to the same spec as possible (lift, duration @.50 etc...)and then a cam that is designed for that little bit extra I'm sure you can get from the LT platform over the LS to see how much more itll go

Dual fueling. We do it at work. Let the direct injection do what it does and then add a fuel rail on each bank for port injection. Worked great for us.

You can also add more fuel by adding port fuel injection on top of the direct injection. You'd pretty much need a whole second fuel system to do it, though, but that hasn't stopped OEMs like Ford and Toyota from doing it.

[@michaelbenedict9549]

You need to change fuel injection timing, spark, and cam timing to see the gains from the headers. It’s a night and day difference. Also you need to do the l86 intake manifold/Tb swap as well. Huge gains with tuning. I wish it was like the fords where they’re DI and port injection. The port injection is where you’d make more power and the DI is for part throttle gas mileage and torque.

freakun Far Out Mr. Holdener! now i'm really starting to appreciate the simplistic yet powerful LS's. already did, but now really am. if i wanted a direct injected variable valve V8 street rodder/driver, i would also want the possibility of mild cam for cruise economy like a V-Tech or the new Hyundai CVVC. i'm just not a fan of mpgs under 18 on the freeway and under 12 in town. it's 2020 after all, and i know how to make high mpgs AND power both, but can't with an LS or LT(yet), but still would pick a 5.3 or 4.7 and pump it up to get the best i can get.

Something I can say with confidence is that the heads on LS engines flow better than L83 heads. That’s the reason why the long tube headers did not make much difference on this set up. I would love to see the gains of just the heads then add the LTH again.

[@richardholdener1727]

I don't think the 706 heads flow more than the L83

Stock LT1 fuel system tops out at about 550whp. Then you have to jump up to LT4 injectors and fuel pump and then that’s only really good to 750whp. And you can get about 850 with a good cam with the more aggressive lobe on the cam for the pump

[@rongravel4585]

The 5.3 and 6.2 have different cam lobes. The pumps are the same and the injectors. And yea 15% is a good round about. It’s usally like 18% in a auto and 12-13% on a manual so a good round about is 15% pretty much covers everything Every combo robs a lil more or less power.

[@mike91b58]

If you really pump the boost to L83 or any LT you might want to consider running port injection. The DI stuff gets stupid expensive towards 1000hp. The big boys are compounding high pressure pumps via a belt driven pump and the cost is stupid. Big injectors and big pumps can run 10k$ or more. You already have a Holley controller and all kinds of intake manifolds for the ls stuff so just buy a set of adapters for the ls intake manifolds. Send this thing to the moon. I have a 15 Silverado and have been running a turbo for two years now. DI cost is the biggest limiting factor in the LT engines. As always thank you for the videos.

The solution is a perhaps slightly more convoluted fuel system. Port and direct like other OEM's(TOYOTA) do to eliminate intake valve deposits, add extra fuel when needed and keep emissions at bay.

I've seen the cylinder heads and they are offset valves and just look like a race design. Would love to swap one into a car one day. With the right cam and tune this thing will burn it down!
