Why are LS Engines popular?

Compact and light for their displacement, iron block versions can be found fucking everywhere for next to nothing, fuckloads of aftermarket support at just about any budget.

The lord bestowed the LS upon us and it was good.

>makes decent power stock
>can fit in almost everything

its popular because people who lack the talent to build an engine and know nothing about cars can have a decently quick car for more than it would cost to just build the original engine

its not even that good of an engine

To add to >>17729318, it's also a compact engine, given it's displacement. It can fit in a Miata engine bay with no issue, and it's a surprisingly common swap because it's light and powerful.

It's a robust, time-tested design that is reliable, versatile, and easily fixable/moddable/upgradeable. It makes a great pickup truck motor, and it can be a phenomenal sports car motor. And it is kind of a monolithic presence; it's been around for a long, long time and millions have been made. Literally every junkyard will have at least one or two if not more, and for every 2 in a junkyard, there are probably 3 out on the road.

>>17729381
>A junkyard LQ (The iron-block LS) can take more than 900hp on a stock bottom end
>Not even that good of an engine
Pick one and only one

>>17729464
meh a 2JZ can make 1000whp with less displacement

and of course you have to pull out a non LS engine to try and defend the LS

thats how shit it is (even those non LS arent that great)

>>17729313
good performance fits-all engine

>>17729381
>it's an "I'm a master mechanic who can build a V12 out of beer cans" thread
Post the last engine you built from scratch, faggot

Why does no one swap hemis?

>>17729497
They're more complicated, probably more expensive, and don't really offer the same incredible aftermarket that the LS has. If you're swapping a hemi into something you may well find yourself welding your own headers, which is fine if you know how and have the tools. A lot of people don't.

Ftfy.

An LSX will be cheaper to build, weigh less, and will make heaps more power reliable (and with a better powerband too). Any 3rd/4th gen SBC is objectily superior to the 2JZ, if only in weight.

>>17729497
More expensive, no aluminium blocks, and no swap kits available, which makes especially the ECU stuff very hard. In raw performance they usually outdo both the LS and Modular though (in competitions like Engine Masters for example), since they've got the best heads of the bunch.

Lets just hope the 4th gen Hemi goes out to 426 cubes (for the SRT8 models), has an aluminium block, and direct injection. That'd bring it well up to par with the LS and Mod.

>>17729539
this is so much wrong I cant help but laugh

LS engines are more expensive
weaker
makes less before losing reliability
slower (sorry no LS has come close to the fastest JZ cars)

LS is mediocre garbage for people who dont like cars and/or know nothing about them

>>17729591
That's what people seem to misinterpret about reliability in boosted engines. Every time I see someone posting "1000hp on stock bottom end" it triggers my autism because it's obvious that that person has never built an engine much less a 2JZ. They don't understand that the sentiment only comes from a few guys that have actually built ~1000hp engines on stock internals only made a handful of passes with them without blowing them up. Then you get the benchracers who believe that these cars are running at 1000hp all day because they never see the builders turn down the boost and teardown the motor when they get home.

>>17729902

It's a great engine. Reliable, powerful, fuel efficient. People here are poor and only own four cylinders and eco diesels and either
A: have never driven anything over 100hp and can't conceive what it's like,
B: tried to build their four cylinder up, made 125 hp, then tried to race and got slaughtered by an ls powered vehicle and are mad jealous, or
C: closed minded about anything not japanese.
Even the earliest (1997) ls1s made ~285hp at the wheels, they've only gone up from there.

There is so much truth to this. It is a real shame knowing that more then half of the bench racing keks would think otherwise. To assume that even 500hp does not take a fanatical owner and total disregard for reliability and driveability does a great disservice to the people who actually build or run these things.

>>17731085
You are actually a retarded fuck with zero knowledge or experience if you think a stock internals 2jz can't reliably handle 500hp
A stock internals 800hp build will last over 20k miles easily

>bbbut ebay ricers that fucked their build up and had it detonate at 7000rpm mean I'm right!
You're an idiot
Stop posting any time

>>17729902
It goes both ways
You cry about weeaboos touting 2jz as some god engine
But there are even more dumb shit American fanboys who literally think you can get a ls from a junkyard for less than $500, throw another $500 at it, and suddenly you're making four digits horsepower and it will run for 100k miles without issue... as if it were bone stock
Go bitch about that.. but nah you won't because you're one of those dumb shits

>>17731415
Yes, Both will be unreliable if you run them at full boost. A 3l putting out 800hp is going to be a lot more stressed than a 6 liter putting out 800hp, You don't need to be an engineer to figure that out. If you ran 2 psi on the streets on the LS it'd last a pretty long time and you'd still have usable power across the powerband unlike a 2jz with a huge turbo. Even if you blow the LS it's 500 for a new block vs $5000 for a new 2j block.

>>17729476
yeah, well an lq9 can do it in less bars and last longer than 4 dyno pulls.

the 2jz is about as dependable as any TVR ever made.

>>17732048
Why cant we come to the agreement that the ls is a good engine and the 2j also good.. instead of listening to u 2 insufferable nutswingers.. some peoples kids

>>17731777
>displacement dictates reliability
How does it feel to be this stupid
although I guess that's what you get when you learn about cars from /o/

You can put a bone stock f20c through more shit than a 4.2l audi
the f20c can make 700hp on stock internals reliably... the 4.2l audi can't even make its stock na power reliability

Your logic is retarded
So are you

>>17732139
>displacement dictates reliability

That's why all industrial engines that have to run 24/7 are 2l Honda's with the highest possible hp/l, right? Few engines are worse than the Audi 4.2 so that's not really saying much to be more reliable than it.

>>17729313
the real question is, in all those years, why didn't anyone bother to give it dual overhead cams and 40 valves?

>>17731415
I literally bought an iron LS from a junkyard for $500. Swap kit for my car was $600 tho. Also no turbo. IMO everyone is being a sperg about turboing an LS. Biggest benefit to the LS isnt turbo potential, but just how much HP you can get in reliable stock form for the weight/money.

>>17732272

No such thing

>swapped it into muh chebby truck for $600
Good for you anon

>>17729313
americans like to overpowered everything

>>17732310
>overpowered
dude theres I4's half the size of a small block and they make more power. americans just don't give a fuck about efficiency - basically because they were never told there was any need for it - so they build massive engines instead.

>>17732358
There are NA 4 cylinders making 300+ HP?

>>17732379
inb4 some high strung modded 2L

>>17732285
lq4, lq9, lm7 are all cast iron blocks and LS based.

>>17732358
Have you ever seen a small block in person? They're tiny and weigh as much as a turbo4 engine. Show me a sub 3 liter naturally aspirated 4 cylinder making a streetable xxxxhp and usable torque.

https://www.youtube.com/watch?v=fnq7qja7As8&t=6s

>>17732285
lsx block is ls based and those are cast iron.

>>17732358
overpowered cause they have no idea of what balance is

>>17732253
Because it would be bigger in size given the same displacement.

It's pretty much the best characteristics of all engines mashed into one.

>>17729313
It's cheap and simple, much like the people who say it's good.

>>17731415
>you can get a ls from a junkyard for less than $500, throw another $500 at it, and suddenly you're making four digits horsepower and it will run for 100k miles without issue

Nobody has ever said this.

Tbqh the only bad thing about the LS series is that they don't sound very good. Something like the Ferrari v8 in the Granturismo sounds like sex but the LS sounds like a tractor or industrial appliance.

the LS1 is not a light engine by any stretch of the imagination. 500+ lbs fully dressed is heavy as shit and unless you are getting a C5 engine out of a vette its going to have X-box huge dimensions. its also not cheap because that C5 engine will run you 6k for one that isn't thrashed to shit with a gorillion miles on it. only the truck motors are plentiful and cheap-ish.

any import jap motor can be had for less and will come fully dressed, with less than 35k miles, AND a warranty.

>>17732139

Can any autist here explain why Chrysler/Dodge doesn't do a 426 hemi in the Charger/Challenger it seems like an obvious marketing win and surely the Hemi block is capable of 7+L. You could even make a 440ci cheaper version. Also does anybody know if Fords Hurricane V8 is capable of fitting in Mustang? I know the Hurricane is capable of 7L.

>>17735553

>>17735396

>>17729497
The hemi design is more complex, the ECU is a nightmare.

A lot of the swap applications deal with small engine bays, something that the LS is perfectly suited for. All aluminum, no overhead cams or centrally mounted spark plugs to add head thickness. If you look at the side profile of the heads, they are almost triangular. Tiny package.

It may not be the best V8 by specs, but its hard to argue with results. GM took the best parts of the old small block and just made it better in every way. That, and its dirty cheap power.

>>17729552

Considering there's 3 engines to choose (ls1-3) plus a variety of 4.8-6.2 liter lesser LS engines. 2 block generations, multitude of aftermarket brands, and ability to mix and match across generations. You can get fairly creative with your build.

>>17738092
2JZs are long and heavy as fuck, though. An iron block straight 6 will do much worse things to a car's weight distribution than an aluminum V8, so ironically the American engine is the better choice if you want to be able to turn.
Unless you can manage to put the JZ way back in the chassis, but many cars aren't built for that.

>>17729313
Good at what price point? They're popular because they give you the most bang for the buck. Are there better engines? Yes. Do they cost more? YES.

It's the antithesis of German engine design. It's trimming every bit of fat out of an engine, leaving only the essentials, and simply using displacement to rectify for the lack of power density. Reliable, light, cheap, moddable, easily fixable, torque, small, powerband. All you lose is worthless bragging rights like "muh HP/L" and "muh technology."

Speaking more to the overall size as a function of the center of weight. The cast iron block is heavier. but most importantly the package is taller and longer. More weight higher and farther forward.

>>17738600

>>17743058
no

>>17743058
They use iron block LS derivatives, not actual LS motors.
Most shit interchanges between them though.

>>17732497

Alright, seen it too many times in this thread.

Reliability is subjective when it comes to car guys. An LS can reliably be expected to eat it's rear main and oil pan seals and leak like a sieve, for instance. It doesn't make it a terrible motor, but it is a massive problem and an elephant in the room that faggots constantly ignore.

You may be able to buy an old LS for 500 bucks and build it to 450rwhp for 5000, but then you get the fun of literally replacing seals every other oil change lest you turn the bottom of your block into a tar pit.

Objectively, it is the most cost efficient in the short term, but a 340 block can push comparable power at relative prices. By far, the 350 isn't the "best small block" everyone touts it as.
