General LS swap thread.
Also, i have a question for some americans who might know more than me.
I've got a NA supra lying about that i got for free and a couple of LS parts as well.
I've always wanted to build my own engine, so i plan on building the LS anyway, but i was considering dropping it into the supra because...
>The NA engine sucks
>Apart from that the car has a near perfect weight distribution and a 0.95g skidpad rating
>I already have it laying about, might as well put it to use
But i've never done an engine swap before, so does anyone know if putting in the supra will throw out it's really good handling? Are there fixes for this? Does it change the center of gravity?
>>14749786
IIRC an aluminum LS is lighter than the stock engine, but a cheap LS will be a truck iron block. Not sure how much that weighs.
It should change the weight distribution for the better, as the original engine is a fucking boat anchor and the LS is aluminum.
2JZ was a fat as fuck so you'll probably be fine.
>>14749798
>>14749800
>>14749809
no
a fully dressed 2JZGE weighs about the same as a LS1
an LS1 with T56 is only 100 lbs lighter than a 2JZGTE with a 6 speed
stop buying into memes people
>>14749800
This is what i thought but i was wondering...
>Will it change the center of the gravity of the engine higher and throw something out, because the weight distribution is almost on 50/50 stock, so they designed it with a heavy engine in mind.
I did a bit of research and they seem to weigh near on the same, ls is a tiny bit lighter...but won't the center of gravity matter more?
>>14749832
but a LS should have a lower COG
Yea just looked it up, 51 front and 49 rear.
Losing the tiny bit of weight should make it a bit better but i don't know how it will change the geometry of the car going from a inline to a V.
I'm excited about the prospect of the LS swap though, this supra's handling is fantastic but it lacks power and i don't want to spend money swapping a non turbo to a turbo cause its not as easy as it seems.
Since i have shit laying about, might as well go for that delicious v8 sound and response.
Anyone know about superchargers for the LS?
>>14749880
>i don't want to spend money swapping a non turbo to a turbo cause its not as easy as it seems.
its easier and cheaper than a LS swap
>>14749816
>2 extra cylinders with no weight penalty
>m-m-m-maymays
>>14749884
Because 2JZs are just lying around?
>>14749891
he has a NA Supra
he already has a 2JZ
>>14749900
Boosting an NA 2JZ is a lot less effective and reliable than upping the boost on a 2JZ-GTE.
>>14749884
Nah mate, i have nearly everything laying about.
New 2jz-gte is gonna be like 10k, wheras i can get a tranny and the kit to mate the two for like 3-4k.
Plus, performance wise the LS makes power more reliably. I know people will get mad, but it's true. The GTE is not reliable unless you're fully doing forged internals and that's when the price skyrockets.
I can get more torque out of a v8 too for the occasional skid and the throttle response of a supercharger, while doing an easy 600-700 reliably without ever worrying something's gonna blow.
>>14749900
They are different engines.
There's the 2jz-gt and the 2jz-gte.
The GTE comes on the turbo version, if you try and turbo the NA one it is liable to explode. The GTE is slightly better but after a point you need expensive forged internals.
>>14749907
wat
people have made 1000whp on stock GTE internals
a LS cant do that and will need internals by 5 or 600 whp unless its something like an LS9
people have been doing NA-T for years with no problems too
>>14749927
You're right, but if you spend some time on supraforums and read what owners have experienced, you'll see it's hit or miss.
Some get lucky and some have them blow at 500. I'm not saying it's a bad engine, but i'm not loaded with cash and if it does blow, i'll have to rebuild with forged internals.
I have a NA supra which will need a engine swap to the GTE anyway, so considering i have the option of doing a LS without paying and others have successfully done it, i'm going to try and go that route. GTE engines cost a pretty penny nowadays.
I'm not making it for absurd power either, i'm making it as a fun improvement on a great handling car to give it a bit more power. I don't wanna lose the amazing response a NA car has either.
>>14749927
damn better tell all the guys at the track with LS's making over 800 on stock bottoms they better keep an eye on their unicorn engines. you're retarded.
>>14749816
Assuming this is fact, you can do a much cheaper iron block LS engine while keeping about the same weight as the 2JZ.
Advantages of iron block LS engines compared to aluminum ones:
>Cheaper
>Stronger (can handle more boost)
>Available mod's will work for either
I wouldn't worry about the swap throwing off their handling. You probably won't notice the difference unless you regularly track the car.
>>14749927
An LS can do that. I'm running 780 whp on my stock bottom end LS3, and there's a guy in our club that made 1050ish whp on a stock bottom end. Just like the 2JZ-GTE, it's kinda dumb to stress the engine that much but it can do it.
>>14749972
I don't track it but i go for lots of hoons on twisty roads. Sofar, it's amazing handling, sticks to the road extremely well.
But yea, the meme that the 2jz is indestructible is simply not true. Tough yes, but it's not invincible.
Neither is a LS of course, but it's pretty damn reliable for what i want it to do.

fucking kill yourself anon
>>14751838
oh look
not a single LS
you faggots are pathetic
>>14751838
>blown after a couple of pulls
you do realize there are 1000hp JZ that are daily driven right?
>>14751843
basing a whole arguement over semantics makes you look like the retard. LS is used as a colloquial term for those not autistic enough to memorize lt/lm/lq/ls and fucking digits
>>14751881
its for faggots who are too stupid to remember ftfy
not LS you tard
>>14751890
okie dokie artichokie
>>14751890
It's an LS block you dingus. It's used in several engines and variants of said engines. Like 15 I think. LSx ones are just their performance oriented ones, but an LS9 and and LM7 both have the same block design.
>>14751890
What's it like being autistic?

>le arguing LS engine names meme
its such a shitty bait, it almost makes me want to stop baiting ls fangirls because i am scared they will think we are the same person
>>14751946
damage control engaged lol
>>14751956
how is it damage control dumbass
>>14751946
Go trade your gbp or some tendies.
>>14751962
actually being retarded and then claiming you're baiting is damage control at its hardest fampai
>>14751981
>falling for the tendies meme
enjoy ur sodium
>>14751984
except i am not the dumbass that claimed the 5.3 truck engine isnt an LS
work on your reading comprehension
>>14751994
but anon... I am you.
My 6.0L truck engine was 514lbs dressed with AC shit.
A turbo 2Jz is 594 lbs
>>14751850
>>blown after a couple of pulls
>blowing the spark out on junkyard plugs after 50 some 1000+ horsepower pulls is the same as sudden catastrophic failure
Bump, also curious about what OP's asking.
Anyone know if the center of gravity will be higher or lower?
>>14754573
lower. 2jz is a tall engine
>>14755604
thankyou, appreciate the answer
I have a question, what's the difference between the different types of LS?
What's the cheapest one that could make 500hp reliably and easily?
>>14756160
Read the first article he posted. 4.8 liter engines from trucks are cheap. Just add a little boost.
>>14751838
>>14749816
100 lbs is a lot
>>14756160
Biggest one you can afford with a cam kit, intake and headers will get you close.
>>14749786
How does it feel knowing ls engines will always be inferior to a mark iv bbc :^)
>>14756160
dont fall for the LS meme
a stroker 350 small block with aluminium heads is easily thew same weight, and carbs and distributors will ways be cheaper and easier to install
it will be cheaper aswell
>>14758805
pretty sure that's horse shit my man.
>>14758812
a 350 sbc with aluminium heads will easily weight close to 500lbs, just somke lbs more than an LS
>>14758805
>implying coils aren't vastly superior to cam driven distributors
>implying carbs aren't outdated trash
top kek anon
>>14758948
dumb bitch stick to cooking
>stock ls engines can make 1000 Hp on a stock block
>cherry picking iron block truck motors for this purpose
>>14759295
The cheap LS engines are iron block, it's hardly cherry picking.
>>14758948
Apparently they are. I've had replace many coil packs over the years. No distributors.
>>14749927
>unless its something like an LS9
fucktard. more like any truck block iron 4.8l or 5.3l LS v8
>600whp N/A v8
>not enough anyway
enjoy your bus
>>14749972
>You probably won't notice the difference unless you regularly track the car.
you can absolutely notice the difference with an S10 5.3l swap
handles much different compared to the same truck with a 4.3l v6. and its only like 100 ish lbs difference
>>14758805
LS1 here
>carb'd SBC
fails in comparison to modern EFI because of drivability and reliability
also fuel economy. my 300hp v8 gets 26 miles per gallon.
all amped up
dur LS
dur 2JZ
fuck yourselves the both of you
>>14759738
>he doesnt know u can't get efi on an old engine
>>14758948
i never implied they were, but they are cheaper and easier to install
have fun wiring every sensor or cables in your first engine swap my man
>>14753068
negative vibes maaan
