ls1/ls6 vs. ls2

[UncleBenRep]

which engine of these three would be the best buy for upgrading??? i know the ls2 is the newer of the engines and has more power...but once you start adding aftermarket parts to these engines is the performance pretty much equal???? plus this engine would be going into a 98+ camaro so would there be issues with the ls2?. Also ive been searching and cant seem to find many aftermarket parts for these newer engines.... any good sites for performance parts??? the reason im wondering is that i finally have some money to start a project car and i was going to a nissan but my idea was way too expensive and so i decided on camaro as being a chevy fan.....and i know it would be easier to build up a older small block and stick it in a 80's camaro but i like the looks of the newer camaros....it just seems that there isnt a big selection of parts for the ls series engines. and i dont know how much money it would take to get a ls engine to push 450- 500 hp....nething info would help

Stock wise....
LS1 < LS2 < LS6

Modding...
LS1 < LS6 < LS2

The only reason the LS2 is better for modding is the cubes.


My old LS1 had roughly $3000 into it an put down 376 RWHP. That is near 425 flywheel horses.
There are a TON of aftermarket parts for the LSx motors.

does the ls2 have the Displacement On Demand Technology or not??? cuz if it does is there a way to eliminate that junk??? and waht about the electronic throttle body....if i was to put the ls2 into a camaro would i be able to just put on a traditional cable throttle body???? along those lines does installing a ls2 into a camaro require a lot of "tweaking"????

No Ls6 is the one with DoD.

Could anyone post up main differances between the ls1, ls2, and ls6, kinda like what makes the ls2 better than the ls1? I'm clueless on the LSx motors, and I don't think there has been a thread telling the differances on here yet.

[drvngstorm05]

are you asking about the differences between the different lsx motors? or are you asking what makes an lsx motor different from other sbc's... because we have had quite a few threads describing the differences between lsx and other sbc's... the main difference between the ls1 and ls2 is the displacement, the ls1 is a 5.7 (346 cube) and the ls2 is a 6.0 (360 cube or 365 someone correct me i just woke up)

[drvngstorm05]

oh yea and the ls6 is the same displacement as an ls1 but it has a better cam, heads and intake manifold

[Link85x]

What about the LS9?

[97cavalier]

hey mr.luos, what did you do with your old ls1?

[wrightz28]

No replacement for displacement

[UncleBenRep]

yes i know the main differences between them like the displacement and how the ls6 is a revised ls1....im talking about the best buy for modding....like can one handle more power/boost than others.....is one cheaper to upgrade then others....and once you start putting money into the engine...is there a big difference in performance between the three......so i pretty much just repeated my first post.....im looking for best bang for buck because the ls1 is lil older and less performance stock than the ls2 so its a lil cheaper to start out with....but are the prices for aftermarket parts the same???? is my question more clear i hope..

[Nate355RS]

Just wondering about the differance between the LSx motors. So an ls1 can be made into an ls2 with just different heads and cam?

[UncleBenRep]

are you actually asking a question...or are you just trying to be sarcastic and think im stupid....cuz if u are then ur failing miserably....ls2 is pretty much the ls1/ls6 block...but moved some sensors around added the DoD technology slightly bigger bore and ls6 style heads...bla bla bla and other stuff im sure too.......

ok, imma have to go research this a bit, but the short answer is no, there are some differences between the Gen I LSx engines, and Gen II LSx engines. im not going to throw out examples cuz i dont remember off the top of my head and dont want to give out false information.

Also to the best of my knowledge, none of the vettes or camaros yet have been given displacement on demand technology, at least none of the pre C6 vettes had it, which includes theLS1 and LS6. the LS2 and LS7 im not 100% sure about.

The LS6 was an LS1 with intake, heads, cam, and valve changes, as well as computer programing, and different exhaust.

The LS2 is basically to the LS1 what the LT1 was to the SBC. while i believe the major components like heads and intake and such are interchangeable there are some fundamental improovements that were made and im not perfeclty sure how that would impact parts interchageability. One thing you would have to take into account is that a set of cylender heads for an LS1 could be marketed as creating 10.5:1 compresion ratio, but on the LS2 it would be like an 11:1 or 12:1 compression ratio due to the larger displacement.

[89IROC&RS]

oh and in my personal opinion, buying an LSx engine just to take the electronics off and send it back to the stone age, defeats the whole purpose of buying that engine. you might as well go grow a mullet and buy a 426 hemi and put that in with twin 1250 dominators and drive down the road spitting raw fuel out your exhaust pipes.

people who cut up highly engineered powertrain setups, that make amazing power, and get great fuel economy are one of my pet peeves. Why take the aforementioned engine, and then handicap it so that it still makes good power, but gets worse fuel economy..... i just dont understand it.

soapbox moment over
