Well. I've got a decent idea at what my L33 should make since it too will have 10psi pushed into it. It's a stock L33 with 799 heads, it's now got an LS6 intake with 80lb injectors and a drive by cable throttle body. I'm adding a sloppy stage 1 turbo cam as well, and rocker arm trunnion upgrade too. I'm going to be running an intank 450lph in tank fuel pump. The biggest difference I see is I believe my turbo is a little bit smaller than that one and my engine is going into a 2000 zr2 S10 4x4 pick up truck which weighs in at a little over 4000lbs curb weight. I actually chose the L33 because I wanted a v8 swap because the 4.3L never was enough power. Since my truck is a 4x4 it has torsion bars instead of coil springs and I didnt want to swap a heavy all iron 350 into it and since I already have a 70k mile 02 WS6 TransAm I love the LS series of engines and how much power they can make with out being a finicky and twitchy built up engine like the older SBC builds I've done (not real fun in traffic). When I found out that I could do the aluminum block 5.3L that weighs basically the same as the iron block and heads v6 that came in it, i knew that would be the best way to deal with making the power i want and not have alot of added weight on the front end. It should make for an interesting ride. My turbo will be remote mounted in the bed though because I am keeping my A/C. I want to have plenty of power but I still want the nice parts we've pretty much all gotten used to having in a daily driver. The L33 alone is probably plenty of power for most people but I've been driving 400+rwhp cars that I've built since I was 17 years old. My first car and build was an 89 formula firebird with a tpi305 and 700r4. I built a fully race prepped stroker 383 for it and shortly after I killed 3rd gear in the 3500rpm stalled th350 transmission I decided to convert the car to a 6 speed manual and got a low mileage T56 from an lt1 powered camaro (like a 96 or 97 model) it was actually an easy swap but long tube headers that fit it were very hard to find and modify to get them to fit. 20 years later and I still have that car, the zr2 s10 was my second vehicle which was terribly slow though slightly modified (wasted money) to me but it would go anywhere I pointed it, and then I got a low mileage box stock 02 WS6 TransAm 6speed in 2012. I've modded it as much as I'm going to for now and I need a truck to use and I've never found a truck that I like as much as my zr2 s10 so as usual I take a stock vehicle and build it into what i want it to be. Like I said, it should be an interesting vehicle when I'm done with it. Thanks for the info on this build and all the other information and videos yall make here on sloppy mechanics.
What is the redline on that engine. I’m swap my ls6 to preserve it and I got an ecs supercharger that I will be matting to an l33 Any suggestion on what would be a must do upgrade to the motor
If you took this same build and added pistons and rods, what would be the safe power level on just pump? or is 700whp from a 5.3 just not safe with pump, no mater how built the motor is?
If you went with a fully forged rotating assembly you could always stroke it for extra displacement and add lower compression dished pistons (the L33 is the vortec 5300 H.O.) it has flat top hypereutectic pistons which puts it a 9.9:1 compression ratio with the stock 799 heads which are the same castings as the 243s on an LS6 minus the sodium filled valves. If you lower the compression you can run higher boost on pump gas. If you run it completely stock I've heard of people running up to 14psi with 93 octane. For my build I'm leaving the engine alone other than the required sensors, 80lb injectors, DBC TB, and 3 bar MAP, etc. I doubt I'll even bother changing the cam (which can cost me a great deal of power by itself). But everything I've heard and read I'll be perfectly fine running 12psi on 93octane and my low boost daily driver tune will likely be 8psi (I'll just have to see how it feels). My build is going into a 2000 chevy ZR2 4x4 s10 (4000lbs of over built truck with a 190hp 4.3L was never enough). But the zr2 option offered a better 8.5" 10 bolt rear, 4 wheel disk brakes, factory 3.73 gears and a great posi in the rear, plus the 31" tires are nice too. It should make a hell of a good ride. I chose the L33 because my truck is a 4x4 s10 so it has a torsion bar front suspension (2wd has coils) and the L33 aluminum block, heads, and my LS6 swapped composite intake keep it basically the same weight as the iron block and heads 4.3L v6 it's replacing. Also the zr2 depending on the year came with anywhere from a 2200-2400 rpm stall from the factory (the torque rom the 5.3L will easily cause it to flash a good bit higher). I could technically reuse the stall and transmission as is but they are high mileage and with most all ZR2 s10/blazers when running 60mph even on flat ground the converter would constantly lock and unlock because it didnt make enough power to maintain lockup in overdrive just cruising 60mph. I've seen alot of these builds and the L33 is a very strong aluminum block engine. You can make alot of power with a SBE but if you want to do a forged bottom end then get pistons with lower compression and make sure your ring gap is safe and you can add even more boost to it. Run a good tune and enjoy scaring the hell out of yourself and anyone else who rides along. Be safe and have fun.
+John Doe well sir, you have asked a complicated question because the GT45 turbo is a series of turbos, and they are all different sizes, depending on your setup, torque converter, transmission type, and size of turbo, your results will vary
I believe the question that you're asking is "the gt45 that's used in the vsracing denmah kit, strapped to a 5.3.. any way it will be laggy?" and thay still all depends on your setup. research and Google go hand In hand. watch the sloppy seconds video and you will see that these guys LOVE bland blanket questions.
I have no idea on studs but you don't need them for this much power, I don't know clutch brand but my friend who built it says it was bright green and he called it the grave digger clutch lol
Getting far into them, this was a while ago so I can’t remember exactly but 700~ is the limit through an auto and 80’s they’ll go a little farther on a stickshift because you see less loss
My very good friend/tuner made 954whp on his stock bottom end ls6 on e85 with a Ysi blower at 17-18psi. He has belt slip issues and is supposed to be at 21-22. He's on the vette forum under Milan. It all depends on your tuning. Tuning is everything.
+Sloppy Mechanics i love the sound its not like most of the import cars around where i live and i was planing on turboing a v6 mustang i have for drifting and figured id ask
I like this combo. I'm collecting the same parts for my project. How did the 80lb injectors and fuel pump hold up this time? Close to max on the 80's? Thanks
+Clyde bigsby yep it's all about keeping the piston happy they are very brittle cast pieces so easy to shatter, it's also easy to get out of control with the cyl temp and the ring will butt and break the piston, or it will wedge on the way down and the rod will yank right out causing all sorts of grief hah
i have never used anything more than a stock piston rod stock motor personally so i dont see the value at this point and at certain hp levels its not needed
Awesome! I'm planning on a sloppy Vette build with an aluminum block and I was concerned with the aluminum being able to handle my power goals. There's so much paranoia about the aluminum blocks. But for a Vette the iron hinders the handling and weight so I don't really want to go that way.
How's the turbo spool up like , builds any boost below 3000rpms ? I know it's pretty low just want to know because that's where you spend most of the time on the street .
a 80mm turbo will be too laggy for street use,but will shine in a half mile course, better off with something like a 62mm or just go supercharge..that are happy a 3000rpm
+ShepherdsWrench best bang for the buck in nearly every facet of the build decision of going with turbo and overall power, reliability cost etc, an LS1 has weaker rods, less sleeve, less space between cyls etc etc
my l33 came with 862 heads does this change my internals I've been told I may have thinner connecting rods , if so does this hinder me from shooting for 600hp
The L33 is a gen 3 engine but I've never seen a real L33 come with 862 heads. Everything ive ever seen, or read about the L33 is that they all came factory with 799 heads. I have seen a stock L33 with a 243 on one side and a 799 on the other side but that was very rare. The L33 (aka vortec 5300 H.O.) didnt come with 862s. Unless someone swapped them just to increase the compression ratio more. With the 799/243s (same castings) it put the flat top pistons at a compression ratio of 9.9:1. I'd personally find a set of 799s to put back on it. Maybe someone just swapped the heads alone but I'd take the engine down some and check for any other swapped parts. Best to know what you have before you start trying to build it up.
Weird. I just watched a friend run his 5.3 with twin Precision 6262s put down 744 at 14 psi... I know dynos are all a little different, but I've seen some other videos of yours that seemed like the numbers were low... oh well, it's really just for tracking improvements/tuning. The track shows the real numbers...
+Russell Telker i would agree that majority of dyno videos are putting out unrealistic numbers, the cars are not going as fast as the hp number they put down by a longshot most of the time. im fine knowing mine might be "conservative" but at least you wont make 800hp here and trap 114mph
+Sloppy Mechanics absolutely. I've got a fairly local place here that was bragging about an Evo that made 1000 wheel... couldn't run better than mid-10s...
All things equal, is the 5.3 actually a better motor for this application than the LS1? Or is there not a big enough difference to warrant the premium you'd pay for it?
correct the L33 designation means flat top pistons 799 heads good rods and pistons etc there is an alum 5.3 that is a non l33 with the skinny rods and not 799 heads i forget the designation
Also you have the best dyno vids on TH-cam. Love the comments and info you give. No music or other bs.
agreed
that tubing is beautiful

Your vids continue to amaze me as well as educate me. Keep up the great work!!!
FANTASTIC video Matt, and what a cool setup in that car!
Coolest turbo ever
amazing,
I wish I lived closer.
3:02 everyone stands back LOLLL
You can see that first coupler off the turbo sliding off
+Dave424123 yes sir! it was, we spotted it too and tightened it up
you can crank it for a while and you will get oil pressure, might take a while
but you will get it
Where do I see more details about this build? Any issues with heat while idling?
it loves the boost!
The reading at the end shows power vs speed (MPH)...At what RPM did it make peak power ? Any cam specs ?
This guy needs more subs!!
Is there any way you would share that tune.
I have a c5z06 stock but for a vs7875 I'm building. Would be perfect to start with
Thanks
What is the redline on that engine.
I’m swap my ls6 to preserve it and I got an ecs supercharger that I will be matting to an l33
Any suggestion on what would be a must do upgrade to the motor
wow that looks fun
Is it just me or does the sound of power get more intoxicating each time they crank up the boost?
Did u gap the rings?
so over 800hp at the crank?
that's stupid power levels, another good project from you guys
If you took this same build and added pistons and rods, what would be the safe power level on just pump?
or is 700whp from a 5.3 just not safe with pump, no mater how built the motor is?

what studs did you use along with what clutch does this c5 have?

safe power limit for ls1 stock internals on e85 with blower
+TheTurbooneg basically the ls1 and the ls6 have skinny rods and weak sleeves and around 650ish to the tire they become unreliable, in my opinion.
