I have a small question regarding the LS2 and LS3, I heared a guy saying that the LS2 is a week engine, and this is the reason why the LS3 was made.. I feel that it is not correct, I found an LS2 C6 in showroom condition with 9k miles on it, manual 6spd for 38k$
and I'm not sure if it is a good choice after what he told me..
in other words, if you had the choice to choose between LS2 vette and LS3 vette, which is better to get?? from the reliability point of view?? only!
It all depends on your budget. When I was looking I chose the ls3. I wanted the newest engine and the 6-speed manual was new and of course it met my budget. From everything that I have heard and read the ls3 is superior (since I live in the midwest I have only been able to put 250 miles on mine since Nov.). The ls2 is a very good engine with very minimal problems that I have heard of or seen. If it is in your budget I personally would choose the ls3, but as you and I know you will not be able to pick up an 08 with an ls3 for $38,000 unless someone has really driven it. Just my thoughts. Good luck!
According to the 1/4 mile list, the LS2 isn't the weakest If it were me and I were in the market, an LS7 would fit the bill. If not, the next best thing is the LS3...it makes great power with just cai, headers, tune.
The LS3 is a definite improvement, but the LS2 is a strong motor in it's own right. Hell, it was improvement over the LS1 and that was a great motor back in the day.
That said, I got my '08 Vette coupe brand new with 2LT, Z51, and comp gray wheels for $43.4k. If you're going to pay $38k for a used one, you might as well cough up a few grand more and get one brand new. JMHO.
Is the LS3 not pretty much just a plain old LS2 with different heads? If so (which I think it is) just buy it and swap the heads out at a later time for around $1200.00..... also, what year did they add the 100,000 powertrain warranty, 06 or 07, dont remember, but either way if you are looking for reliabilty, you will get it with either motor.

That guy is wrong and your feelings are true, it is not correct.
The LS2 is a great and extremely reliable/dependable motor and has accomplished a lot of great things over it's short 3+ model year lifespan but the LS3 just takes it all that much further and is the hot motor of the future IMO.
Bottom line, can't go wrong with either one.

Well in stock trim that's not entirely true either, not yet at least.
Though on a dyno it is dominant.

No, it's a 6.2L versus 6.0L and there are other minor differences between the two motors as well.
The LS2 a "weak" engine....I don't think so. The LS2 is an excellent engine. If 1/4 mile times are any indication, the last time I checked the bone stock category the LS3 engine still hadn't shown its over-whelming superiority over the LS2, in fact far from it.
The LS3 is purportedly a slightly 'better' engine but the primary reason it's in the Corvette is because of cost-cutting measures by GM. Both the LS2 and the LS3 are excellent power plants.
I bought my 07 (LS2) new back in May after deciding not to wait for the 08's (LS3) to come out, and lately have been feeling a little "LS3 Envy" with all the dyno #'s and bolt-on results posted up on here.....All of that just went out the window after installing my LG headers this past weekend......I love the car all over again; The sound, the power, Awesome!.....No more "LS3 Envy"
Bottom line, get the best deal you can.....You're not making a mistake either way

The LS-2 is an excellent, proven motor. In 2007, you got the 100,000 mile warranty. That said, it's all about your budget. I have a 2007. I will not spend the money at this point and trade up to a 2008 because I can install LS-3 heads, intake, and mild cam (like nightdriver did) for a lot less money. If you can't fit a 2008 in your budget, you would not regret buying an LS-2 vette.

The LS2 has plenty of room to grow with you over time if you want some extra hp. All you need are a few bolt-ons anyway and your reaching LS3 stock power levels. Heads/cams are proven reliable mods so even after upgrading you can feel confident the motor will remain rock solid.

This is like saying that the LS1 was weak??!!?!? A dumb statement from a dumb person. Those LS1's and LS2's seem to be doing just fine. My blown LS2 seems to be pretty stong making 548rwhp with just the A&A blower kit and a catback. No other supporting mods, so I suppose mine is pretty much not weak.
The LS3 is the evolution of the LS2/LS7 development so we probably wouldn't have an LS3 without the LS2 to build on.
Don't forget the lowly, 400hp LS2 C6 stomped the 500 hp Ford GT500 in various head to head road tests those first few years...so if that's a weak motor it's one I can live with.
