For one you want to bore it out to 2.8L. you're going to have to fit a monster single turbo, variable valve timing, forged crank, conrods, pistons, N1 block, new heads, new intake, exhaust, ECU, etc etc etc

By the time you get there it's really no longer an RB26 at all. The realistic max for an RB26DETT is 600 horsepower if you care at all about response. Even then on the street the engine will feel dead. If you want response on the street your max power is much closer to 450-500 at the crank. Conveniently if you do the math this is roughly equivalent to how much power per liter the VR38 can make with stock turbos and some light mods.

>>15755443
Taking the block to a machine shop is skill? Basic engine assembly is something lost upon the unwashed V8 peasantry? Not to mention pretty much all that, verbatim, you'd do to make serious power with an LS engine.

>>15755506
Rebuilding an engine isn't some dark art only practiced by reclusive masters of old or some shit, it's a well documented, detailed, rehashed and driven into bedrock procedure. Working out what combinations of parts will make your thousand horsepower WOULD take a bit of skill- But it's been done before and that's all documented and put up for all to see. It takes skill if you want to be a pedantic dictionary definition type, but let's not bullshit each other. Porting cylinder heads is a skill, fabricating a Watts' link (with proper geometry) into a car that never had one takes skill. Unless you're doing some real nasty off the wall combination with basically nothing off the shelf or an engine that doesn't get much love, engine building is pretty basic.

>>15755506
No, it really doesn't.

In the past where you had shitty 98RON, pathetic injectors and journal bearing turbos that ran red hot, yes.

With ID2000s being not just a thing, but a fucking cheap thing and modern ball bearing turbos making a whole hell of a lot less heat, combined with all the years of development, it is not hard at all to make a 1000 flywheel horsepower RB26 or 2JZ.


Spool do a rebuild kit keeping the factory crank and going up to an 86.5mm bore with 8.5:1 compression for $2,395. This includes ACL bearings, which means once you get the block brought out all you need to complete the longblock is a little bit of headwork with some new valves and springs and some decent quality head studs.

You now have the engine ready to take 1000hp, get yourself a decent quality balancer, a well designed exhaust manifold and borg warner EFR9180, a decent intake manifold + fuel rail, ID2000s with the rest of the fuel system to back it up and whatever ECU you like and you're at 1000hp.

It's not hard to make, mate. It's getting it to the ground and doing it in such a way that it's reliable and responsive - i'd personally spend the extra and do an RB30 with the 26 head conversion.

>>15752899
I would get an all-aluminium 3rd gen Hemi.

>>15755266
>new engineering is better than old engineering
Who would have thought?

A properly designed 2016 cast rotating assembly will be weaker than a similar 2016 forged assembly.

>>15755523
It's not the aluminium LS block that faisl. It's usually the rotating assembly on the weaker 5.7 and up units. The 4.8 and 5.3 bottom ends are stout as fuck - and everybody thinks they are, because they're an iron block. However, the 5.3 also comes in aluminium and t's just as stout.

Correlation =/= causation.

>>15755587
>missing the point

>>15755602
Explain the point then, because I'm still missing it.

>>15755599
It's not the rotating assembly, the aluminium blocks unless you get lucky with a particularly thick one have too much flex in them for 1000hp to be reliable, doesn't matter if it's 5.3L or 7L. The max you really want to go on one is around 800hp, otherwise go iron block with massive boost and roll around with 1500hp+.

Same reason you don't try to go more than 1500hp on a stock 2J block, go to billet.

>>15755618
What is it about iron that makes it better for ridiculously high output builds than aluminum? Aluminum is stronger per pound and lighter by strength, so why does it flex?

>>15755609
He stuck his foot in his mouth and had the kneejerk reaction of "cast parts must be weak and can't take power," presumably thinking the only way to make big power is with forged components. I skimped on the explanation on my end that all the baddest of the bad Pontiac 400s used the same damn crank and even until the 2000s or so there were drag racers fueling nitro funny cars making absurd power with those same cast cranks. But I digress, my point was cast parts don't bar you from big power.

>>15755634
Aluminum is stronger per pound, but you don't have as many pounds when it's being poured into the same damn casting as their iron counterparts.

>>15755634
Heat and vibrations, basically. It's actually flex at specific points in the RPM range due to aluminium blocks not being able to dampen vibrations/resonance as effectively that kills LS, AFAIK on things like BMW aluminium I6 it's pretty much all down to heat rather than flex.

Remember though, that this is all at massive power outputs. At 600hp an aluminium LS will last for decades and are lighter than RB30 or 2Js.

>>15755644
>even until the 2000s or so there were drag racers fueling nitro funny cars making absurd power with those same cast cranks

Not literally, the same architecture. Bore and various journal size is ancillary.

>>15755634
You silly fuck

>>15755575
The RB26 crank is a liability at 1000hp, you certainly won't get a previously used one to do that for long.

>>15755689
That same architecture gets cast differently in aluminium - which is why they have approximately same strength and flexibility.

Now, again, this means an iron 5.3 and an alloy 5.3 will be about the same - north of 1000hp if you open up the rings enough. However, an alloy 5.7 might break, because it's a different model. The 5.3 and 5.7 are commonly known as LS engines, but they're different blocks altogether.

>>15755656
Thanks for the explanation. I figured it was some esoteric property of metals like specific heat capacity I'd probably need a college course to understand.

>>15755703
I'm not saying i'd do it, i'm just saying you don't NEED an N1 block different crank and all this other shit to do it.

>>15755712
>However, an alloy 5.7 might break, because it's a different model

That's not a reason. How are they cast differently?

>>15755719
I think the point the anon was making was how do it with a reasonable degree of reliability, rather than just lashing up a one hit wonder.

>>15755679
While they may be Pontiac based engines, I'm still skeptical they're using that same cast crank for nitromethane applications.

>>15755740
from here he seems pretty informed while you just seem to be guessing

>>15755740
Boss Bird runs in a nostalgia class, only period parts are allowed and nobody had forged cranks for Pontiacs available. Mickey Thompson's shit HAPPENED during the seventies where the best damn shit came as handouts from factories and the best they had were the same cast crank.

>>15755732
V8 LS blocks come in 5 kind of sizes (bore)
>3.78''
>3.898''
>4.00''
>4.06''
>4.125''

All these blocks are cast differently, and stuffed with different internals. Only the 3.78'' blocks got really sturdy rotating assemblies (again, 1000+hp if you open up the rings), the others did not (although they're still very capable). Now, since 90% of the 3.78'' blocks are iron, everybody thinks ''Iron block LS'es are always 1000+hp'', that's wrong. An aluminium 3.78'' is just as strong as an iron one, and the iron 6.0's (4.00'' bore) can be quite weak by comparison (they'll fail before they see 900hp on the stock rotating assembly).

>>15755755
you still haven't explained how they are cast differently

>>15755761
>how they are cast differently
They need to have the same external dimensions, while having vastly different internal bore sizes.
You work out which is stronger, uleh.

>>15755773
Yeah I get that. Explain how they are cast differently.

>>15755778
IIRC, the lower bores have a different mold so they waste less making the bores

>>15755786
You said the Alu block is cast differently to the Iron.
Oh and the Iron 6.0s don't fail due to block integrity so you can't use this to say Alu blocks are stronger.

>>15755802
Nigger you serious, of course they're cast differently you're talking about entirely different temperatures and cooling size changes.

>>15755807
the molds are identical

>>15755755
Bore is effectively ancillary when answering a fundamental question like I did, wall thickness is a heat transfer issue more than a structural one, ergo it's unimportant. With as much eye and caliper I've put on them, I haven't seen any real difference outside of material and journal sizes. Your notion of a weak rotating assembly in the aluminum engines is talking out of your ass too since the LS1 and LQ9 crankshafts are exactly the goddamn same, save for the mounting flange on the ass being a little longer.
>>15755786
Lower bores of what? You're talking cylinder bores so there'll only be one bore- This for the iron or aluminum blocks? And still, how is a minor cost saving method in manufacturing some end all to one being stronger than the other? You REALLY don't sound like you know what you're talking about.

>>15755746
Do you believe every outstanding far fetched claim you hear simply because you don't know any better?
I'm more than happy to sit back and learn something new from someone who seem to be more informed than me, which is why I sparked up this conversation.
>>15755754
The "only period parts are allowed " thing may be true to some degree such as performance parts, but there are still modern safety and manufacturing processes applied to the nostalgia class. And I'm willing to bet in order to keep things competitive in terms of parity performance and sustained cost when competing with the more prevalent Chrysler based Hemis, there'd be concessions made for such components to be manufactured in methods that were available during the period anyway.

>>15755817
No they aren't. If you pour aluminium into an iron mold, it'll harden differently (and badly at that), and the end product is weaker.

>>15755827
>Your notion of a weak rotating assembly in the aluminum engines is talking out of your ass too since the LS1 and LQ9 crankshafts are exactly the goddamn same, save for the mounting flange on the ass being a little longer.
I am literally saying that the 3.898'' and 4.00'' bore blocks (like the LQ9 and LS1) are weaker than the 3.78'', and that aluminium engines are not weaker than iron ones.

>>15755838
>No they aren't. If you pour aluminium into an iron mold, it'll harden differently (and badly at that), and the end product is weaker.

It's an NHRA sanctioned class. With rules. Does that escape you somehow? Do you think F1 officials let the other drivers kick Senna in the balls before a race for the sake of "parity?" And say I'm talking completely out of my ass here- Pontiacs didn't have aftermarket cranks until the 90s and pretty much nobody outside of the factories had the tooling to make forged crankshafts and the few who did were already making them for Chevrolets. All of Mickey Thompson's Pontiac shit ran cast cranks because the factory made him- Free advertising. Is any of this sinking in? Or at least tell me the grounds on your staunch dismissal.

>>15755817
>the molds are identical
Yeah nah you're a fucktard with less than zero knowledge of metallurgy.

No, F1 officials simply mandate all cars are built to an equal standard. Which is the presumption I'm coming to with the Nostalgia class.
>And say I'm talking completely out of my ass here-

Grade 6 titanium is highly dimensionally stable and an even worse conductor of heat than zirconia. So it won't seize in the bore and the vast majority of the heat is rejected from the engine and escapes out the exhaust.
>beats the ever living shit out zirconia coating, exposing magnesium housings to combustion
The zirconia and DLC coatings both feature high hardness and high lubricity. As long as the eshaft doesn't flex allowing the rotor to contact the housing and the apex seal doesn't chatter, there shouldn't be any issues.

Nigger are you stupid? Money isn't an issue, so start with an aftermarket block. Aftermarket chevy small blocks support up to 662 ci these days. That's 9.8 liters. At that point, 1000 naturally breathing horses aren't even hard to get anymore. A hair over 100hp/L isn't even that stressful for an engine, nor does it require a really crazy camshaft you can't drive on the street, either. Better buy a good double plate clutch, though.

when i think of 1000hp ls1 i dont think of the super fancy aluminum block all tarted up to make dyno pulls all day, first thing i think of is some rattle can painted iron block motor pulled from a motorhome with two carburators and a blower slapped on top.

ls1 just makes me think of the standard generic 350 made out of better materials.

>>15753473
The engines don't seem to be the weak link on Veyrons.

Tyres and wheels are consumed at an incredible rate, and the cooling system seems to be fairly vulnerable (with ten radiators what do you expect, ten times as likely to get chipped by stones and whatnot).

The engine and gearbox seem fairly bulletproof, which is a big plus considering how (and by whom) they're driven...

so essentially where we are here, is that an LS1 cant do 1000hp without changing the parts that make it a GM LS1, and bringing in major parts from different motors (LQ9, LS3, LS7, gen 1 SBC, or aftermarket patterned after such) whereas the RB26 is well known to make it on the factory block, crank, and head.

>>15756758
But not on the factory pistons and rods, so you're opening it up anyways.

If you throw enough boost at an LS1 with an aftermarket block, but stock crank and heads, it'd still make 1000hp, just like the RB (granted, no factory block). However, had OP specified the (objectively otherwise inferior) 5.3 instead of the LS1, it'd be differene - it can make well over 1000hp on a stock shortblock (except for some gapped rings).

>>15756660
Are you stupid?
If money aint an issue then increase compression, huge bore, short stroke, and decrease displacement to 1L. 1000hp/L would mean a rebuild every few hours, but money isn't a problem.

"if money isn't a problem" is the fucking dumbest hypothetical situation to ask about. OP you're a true moron.

>LS1

LS1 owner here


you wouldn't be making 1000hp with a stock LS1, but you could make like 600hp

Not sure why you would want to pigeon hole yourself into the dated and small bore LS1 at this point. The price isn't really that much cheaper. If you really want to go LS1 you'll be pushing the limit with a 1k hp nitrous, turbo, or supercharged setup. At that level you'll want a complete aftermarket forged rotating assembly, at least CNC ported heads stock cylinder heads and probably aftermarket and o-ring the block. The main issue with the LS1 block is the cylinder head clamping force with huge nitrous or boost loads. To build a really safe 1k hp LS1 you'll want to get an ERL Superdeck. It's essentially a custom machined spacer for the top of the block that will let you run longer stroke and bigger cubes without the piston coming out of the bottom of the cylinder bore. As an added benefit the Superdeck increases cylinder head clamping force and generally increases the stability of the rotating assembly. There are drag race engines out there using the Superdeck on stock LS1 blocks pushing 2k hp with nitrous and twin turbos.

But the better option is to get either the aftermarket LSX block designed for boost applications or at least go with a 4.000" and larger LSx like the LS3 block. With those engines you can run much better cylinder heads and not be choked by the small bore.

They're pretty light though - billet aluminium, with just one cam. Most of the cars using stuff like this are weighed down to about 3000lbs. Some can be under 2300 though.

>>15757367
You need forced induction to get real power out of them without spending $30k. $15k will get you 4-500 whp though

i have no desire for that much power. how can you even open it up? seems like a waste of potential. 400 hp is fine for me. anything more is just totally hard to use to its limits.

i can say that if you like to do this kind of stuff, you are not like me at all.

my car is 3500lbs and 250hp. its plenty for me? i mean its not as fast as some of the other cars i have owned, but its enough to get pretty hairy in the twisties.

The old one had 315 from a 4.4 V8, the new one has 410 from a hybrid I4 setup.

>my car is 3500lbs and 250hp. its plenty for me?
For most regular people it would be fun indeed. The hairyness probably comes from the slightly bloated weight.

>it never made me feel i needed 400hp to have fun
Makes sense. I consider 70hp to be plenty on a motorcycle, for example.

If I had to pick a 1000hp car, it'd be some kind of ludicrous drag machine. A turbo LS Kadett, or maybe a Hemi Topolino.

For everyday road use, I could pick either of those cars with properly setup roadracing suspension, and I'd have my hands full at 400hp.

It just depends on what I'd be using it for.

The creator himself, Sonny Leonard has been quoted saying

>If it was weight per cubic inch, this wouldn’t be the way to go.

The billet Sonny Leonard mountain engines are typically around 700 lbs ready to race or about 200-225 lbs more than a LSx or aluminum SBC with a turbo setup ready to race. And still heavier and much larger than a smaller, billet BBC based engine in the 4xx-5xx cubic inch range that would run in a power adder class.

The Leonard engines just aren't going to be competitive in most of the popular drag racing circles right now because many of them have lower minimum weights than turbo, screw, or nitrous cars, but if they can even get to them they're going to be outclassed.
