All the talk about the LS1 motor swap, now the next
gen of the "LS" series is out! The LS2 in the all new
Vette, GTO and Caddy. Anyone here thinking about
doing that swap? I know it's a little too early, but I
am sure some people are willing to do this!

Just wanted to post this link here for specs on the
"redesigned" LS1. I wish it was pictured in an F BODY
but of course, we may not see that until 2006 or so.

Here's another link with specs on the LS2:

Oh, and there will be an LS7 package available too! Imagine
like over 500hp from a factory GM car????? Is it 1968 again?

 

a lot of people will/might wanna do the ls2 swap but unless they have large pockets because I don't think you'll find one in a junkyard in less than a couple years

 

Oh you will find em but they will cost a fortune. I will be lucky to get the LS1 swap done before someone with fat pockets gets one in a third gen! Almost had the LS1 too!

 

Thought the GTO got a Detuned LS1 and the CTS got an LS6 (ala C5)???

 

Till 05

 

I know that they will cost a fortune for many reasons.
Main reason: It's new! But I know there's some thirdgeners
with deep pockets are willing to buy up this new and
improved LS1 motor. If I had waited longer and had
my own garage, I would have done this swap instead
of the traditional gen 1 or gen 2 SBC swap. But, If I
ever get rich some day, maybe I will buy an old 60's
Camaro and swap in a brand new LS2 with T-56.
Actually an LS1 or even a LS6 would be more logical
for me that's on a budget. But, if you want the latest
and greatest, you gotta get the new stuff that's out.
That's a dream now, maybe a reality someday. Just
like how my first project was ( a dream, now a reality!)

I can bet money that GM is cooking up a T-57! Or maybe
a T-7. It's becoming more common to see 5 and 6 speed
autos, so a 7 speed manual is not far ahead.

 

I thought that the GTO got a regular LS1 345hp/345ftlb. motor?

 

on http://www.sallee-chevrolet.com the
ls1 is $5,995.00.
ls2 is $6,375.00.

is this the engine your all talking about?

http://www.sallee-chevrolet.com/Chev...ckV8s/LS2.html

 

its 350hp/365ft pounds

 

GM didnt make the T-56.. did they? I thought that was a tremac or borgwarner 6 speed. (maybe I'm wrong.)

 

Mercedes are starting to use a 7-speed auto at the moment, but in their cars with over 400bhp they are using their 6-speed auto due to strength and durability issues.

I'd love to see a automatic transmission with 6 or more gears in a thirdgen - that would rock!

 

From Sallee:

In ’05, the new LS2 also becomes the standard engine for the Chevrolet SSR (390 hp / 291 kw and 405 lb.-ft. / 549 Nm of torque) and Pontiac GTO.

Just like i said before,

 

WOW, I guess it's not that much more for it. I would
just get the LS2 motor then.




But, for a person on a budget it's better to just wait
out until next year when more are on the roads and
get cracked up and sent to junkyards. For a total
drivetrain swap, it's better to buy everything all at
one time. The motor, computer, wiring, trans and
everything attached to them. Besides, it would be
cheaper to buy the complete drivetrain used. The
price of just the motor new would cost the same
for the complete LS2 package with trans. At least
that's what the LS1 motor/trans. goes for on Ebay.
Like between $5K-$8K for everything used.

 

Uh yeah...close enough.


On the subject about hp/torque, then what is
a detuned LS1? The older (98-02) LS1s got
between 315-325hp with 345ftlbs. from the
4thgens. So, what would a detuned LS1 be
in a GTO when they are rated at the normal
power for '04? (350hp/365ft lbs.)

 

Yes, Borg Warner made them. Which I believe
Tremec now makes them.

 

Whats the big deal about the ls2. Its just a 6.0 Truck block that has been cast in aluminum. I would rather have the truck block because you can bore those out with out the hassles of resleaving. And it only weighs about 100 lbs more.

 

It is more than that. The oiling is far superior. They elimintated all piston slap found in just about every Gen III motor. The list goes on. There were enough differences that GM had to make it the next generation (IV) of small blocks.

 

If the truck motor is the same as below, then
it is no big deal. I just wanted to point out about
the new LS2 design that's going in a sedan!


LS2 Details :

Compared to the Gen III-based LS1, the 2005 GTO’s LS2 V-8 incorporates several significant changes to help improve performance. The block is an all-new casting with cylinder bores measuring 4.00 inches (101.6 mm) in diameter. The cylinder heads and camshaft are revised, too, to deliver the airflow necessary to complement the engine’s larger displacement. Other changes include:
New aluminum block casting with revised oil galleries and provisions for external knock sensors – external sensors improve serviceability
Camshaft lift increased to take advantage of increased cylinder head flow
Camshaft sensor relocated from the rear of the block to the front of the block provides room for new oil galleries
Flat-top piston design with lower ring tension reduces friction
Piston floating wrist pins help quiet the engine
More efficient ignition coils require less energy to provide a comparable spark
Compression raised to 10.9:1
LS6 heads
Larger, 90-mm single-blade throttle body
Reduced-mass water pump design with improved sealing capability
Engine “redline” raised to 6500 rpm
Revised and more powerful engine controller incorporates all electronic throttle control functions

 

Its nice to see GM moving away from the standard set with the 5.7 (a 5.7 hemi...considering the 1968 hemi was a 7.2 liter engine, can i not help but feel disappointment?) and into something different.

 

yall guys are funny, there is a place around here where i can get a complete pan to intake with accesories and coilpacks for under 1k delivered, this is a low mile pull out of a wrecked vehicle which this has a 12 month warranty. then im gonna get the 499 front member for ls1 , bolt my th-350 to it and be done with my swap. complete out the door 2k tops. i might spend 4or 5 hundred and get the block re bearing and ringed so i dont have no probs and then pick a good cam and spring set, cam only ls1 in a thirdgen on a 100 shot with a th-350 should do pretty good

 

yall guys go ahead and spend your 5 or 6 k on a crate motor ls1, ill get a used one rebuilt and spend half the cash installed and we will see who comes out better, i think it is histerical that yall would even consider a crate gm motor when the salvage yards are full of f-body's and trucks with 5.7's and 6.0's for sale for cheap. there is just a smarter way to go about it and i dont think anybody wants to throw away 6k on a crate motor when you install it and run it you have the same thing........a used ls1

 

Have fun rebuilding an ls1. Especialy over boreing it oh wait you cant it needs to be resleaved. New is new not rebuilt

 

anyone selling a ls1 with the wiring and all accessories for 1k would have to be on crack.. buy all u can at that price

and a new engine is kinda hard to compare to a used one if i had the cash i wouldnt be messin around with a used block that could blow up 10 miles down the road but im gambling with a used setup..

 

Anyone see on "Rides" on the discovery channel last night?

Jay Leno got ahold of the LS7 and Twin Turbo'd it for his new project car.

 

whats the number to this place that sells complete ls1 for under a grand?

 

It can be overbored. The sleeves are thick enough to allow for up to two .005 or .010 overbores (or around there). Even the Iron block without sleeves is limited in the same mannor. CHP did a huge write up awhile back on increasing the cubes on the Gen III mill.

 

The iron block doesnt have sleaves. Also I dont even think they sell pistons for ls1's that are .010 over. .005 over is like a little more then a hone anyways.

 

I know the iron block doesn't have sleeves and I mentioned that. You can still only overbore it 3 times and then the block is junk. That is why you will see every new 6.0 shortblock start with a stock 4" bore. They need to allow the customers a few rebuilds during the life of the motor.

 

i already had fun going .10 over on my wifes blown ls1, why dont you do some research on something before spouting about something you have not a clue about

 

well i guess best automotive off of mcarty is on crack about 5 times a week

 

the last motor i saw bought out of there was a complete 6.0 longblock for 550. oilpan to intake, the accessories and coilpacks are not more then another 200-300 from them

 

if it blows up 10k down the road , thats not the motors fault , thats builder or installer error, i have a rebuilt ls1 on gas and boost in my wifes car that has got 25k on it and doing great, but you go ahead and spend 6k for a stock crate motor when you could get a 408 or 427 ls1 for almost the same price

 

its a rebuilt piece of crap, i paid about 600 bux for the longblock for this rebuild

 

car

 

sorry repost

 

i cant post for crap, oh well, here is a pic of her ls1 and my thirdgen im talking about converting.

 

nope the pistons i put in here car two years ago are imaginary

 

im not seeing a Best Auto off from mcarty. there are a few around houston and beaumont, Tx. do you have the numver of town it is located in?

 

i know which best xtremeirocz is talking about, i pass by it every day. about 2 years ago they had a complete 2001 LS1 with PCM, wiring harness, exhaust manifolds, starter & trans with drive shaft, it was sitting to the left of the front door as you walked in. they said it had about 20,000 miles on it, asking price was $2,500, if i had the cash to spare back then, my car would be LS1 powered now.

their phone number is 713-676-2137

 

yep and that was 2 years ago and without a shop discount which i can get, im telling yall guys there are cheaper options

 

ok, i called up best automotive and best core both on mccarty and found a few deals on stuff, a complete 5.7 oil pan to intake with accesories for 950$ and they say it has 40k on it, they also had a 6.0 with iron heads for a hundred more with the same accesories. they said they had a ton of the 5.3 ls1 's out of the trucks that made 285 and that truck intake would fit easy under a thirdgen hood. im almost thinking of that, those complete are around 650 to 750. anyway, if i pick any of these up , get a painless harness maybe have new rings and bearings put in i could definetely put the swap together for under 2k or around that. now if i could just sell this stroker motor!

 

are these ls1's, or are they iron blocks? did you ask them if they had any ls1 complete with trans and everything? i tried calling, but im never around during the day, just later at night

 

well the 5.3 and 5.7 are not iron , the only iron is 6.0's and they are all ls1 design, im sure they have them with tranny and everything if thats what you want, i didnt ask though. ill probbly cruise down there tommorrow or thurs. and see what they got.

 

sent you a pm

 

I believe the only aluminum LS based engines are ls1/6 and ls2.

4.8/5.3 & 6.0L(LQ) are all iron.

 

All truck LSx engines are iron. It'd be the only one i'd swap in my car too. Me no likely aluminum block.

 

yall guys are right i went down there and picked up a 5.3 complete with accessories today

 

the only thing i have agaisnt the aluminum blocks are that they are so fragile, but they are light as hell.

 

2nd Fastest LS1 in the country belongs to Harlan on LS1tech. he's gone 8.29 or so on a stock ls6 block and crank... weak?

 

they are fragile, go assemble a few and find out about their bolt threads, and where they like to put coolant that is down in a headbolt hole that you couldnt get out, their crack rods are crap, their cranks are descent. that guy doesnt have a stock ls1 crank and block its a sleeved stroker motor, the fastest stock bottom end ls1 is 9.60ish and was set out at baytown last month
