Possibly due to the fact that the s/w to tune the LS2 is in BETA testing stage, so no one can really alter ECU until the tuning s/w is released in about 5-6 months!

50lbs lighter would seem to be a massive drop in weight ?????
I'm no engine designer, but I dont see how they managed that when the 5.7 is already all aluminium.

The 6.0 block is an unkown quanitity, with its open deck almost wet liner design, which could prove weaker for big power builds over the 5.7 engine.

Time will tell if people start pushing the 6.0

It goes better because u now have a VXR, u had a 5.7 in a lower state of tune. Having driven the new 05 car with 5.7 and a mild tune i can say that the CV8 owners are very well catered for over the 6.0 car.

<RANT> VXR SIX, What point are you trying to make? It's blatently obvious that 6.0l has more power and torque than a 5.7 so you don't have to keep educating us 5.7 owners on that fact. Also with a few 'careful' mods I would expect my 5.7 to have at least as much power as yours for a LOT less money than you paid for yours. Not sure if your intending to wind us 5.7 owners up but thats the vibes i'm feeling. </RANT>

I agree with your sentiments booster, I am sure that with a few careful mods the power and the smoothness of a VXR 6.0 will be yours and your point is well made about the cost!

I can vouch for that - 400 + Lbs/Ft 416hp and a NASCAR sound track!

There are lots of ways of enjoying these great cars and trying to enjoy them more! Thats my perspective anyway. There is a set up I wish to achieve for my car and that is probably different to some others.

If I had just bought a 6.0L VXR I would be happy as a pig in ***t.

I was at a RR day on Saturday and there was a fantastic looking red 04 VXR and a rather smart blue/grey 05CV8. It is interesting and valuable (IMHO)to just share what different people with different set ups are experiencing - you might learn something!

Some are lucky and can afford the VXRs (Monaro owners that is remembering this started life as an HSV forum) with the benefits that brings (its not just the engine - diff, suspension etc.)and others who cannot have found ways via this forum and its helpful members of modifying the great base cars in line with their wants.

We are all lucky enough to have been able to buy into these fantastic cars.Lets remember that.

From where i am sitting, it doesnt seem any 5.7 owners are getting 'sulky'. It seems they are pointing out the error in your comments, and asking why bother making such unfactual remarks, most 5.7's on here offer more power, torque and responsiveness than a std 6.0. There is also more to how a car drives than headline figures alone.

Maybe as and when u have a dyno sheet showing how much or little power u have, u can then comment in a more informed manner.

This forum isnt about one-up-man-ship, it is about enthusiasts with a common passion, all of who appreciate the benefits and merits of each model, without trying to put down one or the other!

Without lowering myself to a base argument with a misinformed and inflamatory individual, i will just add to my comment. If u have all the power in the world but cant deliver it because of transmission or electronic issues then the headline figures are not representative of real world performance.

If u actually have a 6.0 car that is!!!!

Testosterone-City is it today, boys?

Look, many people would have spent £22K on a used 5.7 and then made it faster and how they want it, for another £8K. You then have a faster, cheaper car than a stock 6.0.

Others will prefer the latest and biggest. The improvements that go hand in hand with evolution.

It is all a matter of taste, choice and budget.

Get over it, it's life.
It's motoring.

My point is that this was a far happier forum until you started posting, why don't you go back to the gassing station period.

I'm not sulking just pissed off

Going back to the original post, in standard form it seems from what I have read & heard(I've only seen & heard a LS2 in a Chevy pickup) that the LS2 is smoother & more "refined" than a standard tune LS1.
However, I'm personally concerned to hear that the LS2 is so much lighter.
This reminds me of what happened to the Saab 4pot engine as used in the "classic" 900 & 9000, although unsophisticated this engine was incredibly robust, capable of huge mileage with excellent reliabilty & in 2.3T form capable of handling upto 300bhp with no problems.
It was basically as good as it was ever going get. But the GM/Saab engineers have got a job to do, so they went about lightening it.
Result, big loss in reliability for the more powerful models & little scope for any power modifications at all.
The LS1 has many similar attributes to the early Saab engines. Lets all pray that the LS2 will be just as reliable & tuneable as the LS1 which we know can handle upto 1000 bhp with ease!
IMO the LS1 is a true claasic of an engine & I really do hope that the LS2 will be as well. Time will tell!

LS2 is just a larger bore LS1 (or more precisley an LS6) as similar power / torque - just a bit smoother from what I here to. Same weight.

Afternoon. Interesting thread which reminds me where the whinging pom comes from, please no offence intended.

I recon it is nature people want to think they have a great car, 5.7 or 6.0 and be proud of it, of course there will be a little feeling of rivalry between them but there are ways to express this without being hostile.

Personally I know little about the cars and that's why I am here reading from some of you very informed individuals.

I have been in the states for a few weeks and I learnt a couple of things over there which people may or may not know.
The LS2 was designed to celebrate Chevy's 50th anniversary and the American Consumer and Guide for 2005 cars, the Pontiac GTO is rated as the best buy in it's class, I enjoyed reading the footnote in the article which stated: Made in Australia :-)

The LS2 has a weaker block, less coolant capacity in the block and a weaker water pump. This is just a start. The water jacket has a higher floor, hence less coolant capacity. The liners have thinner jackets and are siamesed together which will mean less flow around the cylinders. There is some flow around the top of the bore but this part of the block is weaker. The LS1 block is probably the strongest normal production block.

That said it's a decent motor but until people start tuning it nobody really knows what it's weaknesses will actually be or even if there are any that will pose problems. Personally I prefer the early 5.7 plus there is a lot more tuning stuff for this engine. To compromise a block for the sake of 300 cc doesn't make sense so it must be ok for normal use.

Boosted.
