Out of the box the LS2 is better. Fatter and flatter power band. For mods the LS6 is better in the CTS-V as there's more out there on the shelf right now. However I'm sure most pieces are interchangeable as far as heads, cams, CAI kits, etc. Not sure on the headers though if the ports differ.

The LS6 is better because it's in my car. The LS2 has cooties.

Seriously though, did you know that July is National Blueberry Month?

ls6 all the way.

Here's Why:

1 There's a reason it was in the special edition corvettes (known as the z06).
2 More Efficient HP than ls2 (5.7 liter making 400 hp vs. 6.0 liter)
3 Cooler to say "i've got a z06 motor"
4 Every new vette, SSR, goat, Trailblazer SS, yada yada yada has them.
5 CTS-V was designed with the z06 motor in mind, not the ls2
6 More aftermarket goodies currently available
7 The Strut tower brace says LS6, not LS2
8 Its the Z06 Motor
9 Its the Z06 Motor
10 Its the Z06 Motor
11 Its the Z06 Motor
12 Its the Z06 Motor
13 Its the Z06 Motor
14 Its the Z06 Motor
15 Its the one that's in MY car Therefore, better

Hope this shed some light,

Ben

hello people, im new here..... i got my v 30 days ago..... and loving every minute . Ill be posting my impressions, but so far i have to say cadillac has hit a grand slam. I jammed the brakes from around 93 mph and i thought to my self " BMW" never felt this good. I know ive been driving them for 20 years. This baby is a real sweet, she corners beautifully. I her ran around some of my favorite secret wiggles and wow, she's on rails. From the launch she violent, quite a dramatic thing, the hop @5500 to for taste i love it, reminds me of first ave days......joe 207

The LS6 is a better speed engine. The LS2 is a better base engine to have in a car as it doesnt need revving to pull but the LS6 is better. There has been many tests of the old zo6 vs the new base corvette and the old zo6 pulls better. LS6 for the win

Default LS2 vs. LS6

Since I have both-LS6 in my V and LS2 in my C6--I think I can give an intelligent opinion (at least I hope so). So much as it hurts me, since I like my C6 but LOVE my V, the LS2 is a mcuh better engine. Smoother, better power band. etc.

Of course, let's wait until the V gets the LS7.

Certainly not wanting to rain on everyones parade shouldn't you really look at the characteristics of the engine in determining which is "better"?

The LS2 is in a way more an LS6 than anything at all. Given the fact that it shares identical LS6 heads and a 2001 Z06 cam. The revlimit is likewise 6,600 and the compression has been raised to 10.9:1. The LS2 incorporates a 90mm throttle body and has an entirely new (not so great) PCM.

I certainly enjoy driving LS6 cars and also LS2 cars. They are just a little different. Where the LS6 really comes to life up top the LS2 just continues to pull from just about anywhere in the rev range.

Sure their will be fewer LS6's on the road but does that really make an engine better?

As I stated above, the PCM is completey different in the LS2 cars and incorporates many more fail safe features that are zapping performance in less than ideal conditions. Torque Management on both automatic and 6-speed cars is also a concern. Removal of such devices has created some beasts without any bolt-on's what so ever.

Just my opinion.

You have covered evrything....LS2 nudges out with a slight advantage in my book.

How does an older motor have more design into it? You think they just start out fresh with every motor they make

So many of you who have LS6 motors sound like Viper owners trying to defend your car against a cheaper and better performing C6ZO6. It's rarer, it looks better, blah blah.

What you just said has nothing to do with whether one motor is a better motor than the other. The LS2 motor is a better motor, especially when it comes to potential. Many of you will really start to realize it when tuning software and more mods come out for it. There's no replacement for displacement.

This is a good topic.

My .02

I'd prefer the LS6 over the LS2 at least for the time being.

There are more mods/ parts available for the LS6 simply because it has been exposed to the market longer than the LS2. Picking one engine over the other based on which car they are in is an unfair way to base a comparison off of. And saying the LS2 is smoother than the LS6 when comparing them in 2 totally different cars is unfair as well.

If anyone read the latest Corvette Quarterly it compared a Z51 (LS2) Vette vs the 04 Z06 (LS6) on a race track. The 04 Z06 inched out the 05 in performance. The LS6 car put up about a second quicker lap times than the LS2. They are both very good engines, and each have their own characteristics and really in each case racing those cars, the little difference there is in perforamance, the better driver would always win. I would consider the LS2 to not be fully dialed in yet. I'm sure they may some new parts on it, so its a damn good engine already, and I do think there is more potential in the LS2. We'll have to see how good it reacts to modifications when more are available, but for now, I think its too early to compare apples to oranges.

same as its always been, more displacement usally means more gains and potential and it all depends what you wanna do, stock for stock id still take the ls6 but thats my own opinion.

your beating a dead horse though really.
