As the title says why didn't GM put the LS2 in the GT version of the G8.

Probalby because the LS2 is being phased out.

Seems like it just got here.

I know, I totally wanted an LS2 as well! It seems like it would be easy to mod, with many available mods / companies out there for the 05-06 GTO and C6 Corvette already available.

:soapbox:

They do not use the LS2 in the land down under?

LS2 is being phased out within the next few years - and the G8 GT is going to be the mid-level model, so it shouldn't get that top end of an engine. The G8 GXP will be the top of the line model and will likely get the successor to the LS2.

See what HSV's next engine is for a clue ;)

Maybe it's so us GTO owners don't complain about the Grand Prix having an engine equal to ours. Who knows, maybe it will help our resale value by the LS2 being more rare.

I am sure it won't be hard to mod this new sucker either....

The engines are basically the same, being both based on the GenIV block.
Although the DOD slated for the L76 in the G8 might have been a reason why the old non DOD LS2 wasnt used either.

Rest well knowing the heads are much better than the LS2 heads out of the box.

Those are the same heads as on the L92 6.2L in Escalades, Denalis, etc. I'm presuming.

these heads are L92 if I am not mistaken so they flow like CRAZY about 330cfm bone stock,so some cam swaps+springs etc should make some crazy power on the L76

:yumyum: I can't wait.

thats what i like to hear :D

No, they used the LS2, but not as much as what we did here.

Yep, I see a 415 inch block, a cam, and some tuning making 522hp and 500 ft lbs of torque in this thing. That's using stock heads and cam. This 4 door will rock!

Okay, now I'm starting to feel better! I did hear that the heads are very good.

A CAI, Cam, and Computer tuning sounds very nice! :D

Lets hope so. Cam only cars will be making a ton of HP, if that's the case.

Just have to think about piston to valve clearance but I think it may be much less of a problem with this block than the Lsx

The LS2 is being replaced soon, and doesn't pass the more stringent emissions standards now in effect in Australia and Europe where the car is also being sold.

Think "LS3" for the GXP edition to follow......430 at the crank boys!

Still can't wait that long.

Anyone have any hard evidence on the LS3? Displacement, bore, stroke hp, tq, etc... or is it still drawing board?

The only things I can think of are probably an L92 with a bigger cam. Possibly the 3-valve heads on it.

I wouldn't bet on the 3-valve heads... the current thinking over at LS1tech is that the 3 valve design in question is probably going to be a truck head and its set up for increased torque and fuel efficiency... and thats only if it produce at all.

Of course I could be wrong and if they put together a 3 valve head that kicks it, I'll be first in line!

Yep... It's a goner.

No matter which V8 it gets, Pontiac :ftw:

Go to HSV web site and look at the GTS... has LS2, 415hp.

I dont know specific specs on the LS3, but it is a 16v and you can go pick one up right now at your local Chevy dealership in the new base model Corvettes.

this is looking promising with the L76

As soon as i hear of one coming out w/ the LS3, i'm getting that over the new camaro then heh heh. I love my aussie made car and i want to keep that momentum going. Just wish they would have brought the Falcon Typhoon turbo model down here.

If you truly do prefer the Falcon, well I can assure you that Ford will bring it to the states. Theres been a lot of LHD testing on the next gen Falcon.

But in my opinion Commodore > Falcon :)

The LS2 is now effectively phased out in favor of the LS3, the L92 block being the performance base to build the variants upon. It saves money to GM directly and to the aftermarket by having one standard to build upon (think about it, the 'vette, blue devil, camaro, and g8 will all have a derivative of the 'slade/denali block)

The GXP I'm betting will get a LS3, to share the "performance top dog" idea with the 'vette and the 'maro (which leads me to believe that the GXP will come out right around the camaro's debut)
The GT will end up using the truck engine L76 so it'll be a 87 octane runner(pays dividends when your out in BFE).

As long as it's a Gen4 block it don't matter performance wise, they are all more or less equal within 5%, and on the extreme end effectively equal.

What'll be of real interest is bypassing the Al blocks, and dumping in either the crate 454 LSX(not LSx), or a 500" stroker LSX variant; and completely obliterating small block torque convention. I'm either going real modest, exhaust, intake, tune; or going big with a 496" combo stump puller when other projects are done.

OKsweetrides, hoping for a 496" :D Be sure to take tons of pics!

Someone will end up making a monster cube highway roller outta these and it'll be a vile brawler for folks interested in a real brute. Think linebacker-in-a-tuxedo

Might have to hold out for the GXP......

I'll sell them, but even with an LS3 in it the chances of me actually choosing to buy one will be slim. They are going to be very very heavy even with the LS3.
If I did buy one my first mods would have to be:
1: Rip out airbags (side and front) and all associated hardware
2: Rip out half of the sound deadening
3: Take out all extraneous hardware (i.e. extra computer for TPM, Stabilitrak, etc)
4: Deactivate Stabilitrak
5: Pull front seats out for lighter weight less comfortable front buckets
6: Yank all extraneous plug outlets
7: Pull out all useless wires

And now I've got a car I'd like to drive that will be uncomfortable and generally not useful in its class.

Sorry for the thread hi jack especially as it is my first post.

Thats a horrible idea. To spend all that money on a brand new car and then just rip out everything just to make it lighter, I think money would be better invested elsewhere.

You are absolutely correct.
I completely agree.

Hell buy a mustang 8-10K cheaper and add a turbo and you are on your way to 500HP with 3-4K in your pocket.

Don't listen to the clueless noobs. If you want a light car, get a 2008 Corvette. You will not find a 400+ HP sedan from the factory that weighs under two tons.

If the G8 comes with the LS3, it will be equal with the 4000lb+ SRT8s and hopefully cost less and have a nicer interior. Plus the aftermarket will be better :)

I am sure it won't be hard to mod this new sucker either....

New engine is moding well :]

See VE 6.0litre stuff on http://russoperformance.com.au/index.php?option=com_content&task=view&id=36&Itemid=40 considering flywheel kW is rated at 270 factory standard and Russo are claiming 270rwkW is an easy target :]]]

Tbh, I am in love with the 6.0 in my VE SS V-Series :]]

rawr: Have you taken your 6.0 VE SS-V to the track yet? If so, what did you run the 1/4 mile in? Stock? Modded?

Do you have any mods on it?

(I cannot wait to get my hands on my G8)

Well I think #3 would take care of #4 for ya, so I just saved you a step!

But, like others have said, this isn't meant to be a light racecar, it's a powerful, sporty family sedan, meant to compete with the likes of the Dodge Charger, which actually outweighs it by a couple hundred pounds!
