Stock GTO VZ Power output

[PC12]

I have been told that the LS2 motor HSV used in the VZ GTO was a stock motor with nothing done to it. Power output 297 KLW. So the LS3 used in the SSV utes are shown as 270KLW for the manual and 260KLW for the auto.

Are the SSV LS3 motors derated then over the GTO LS2 because of the way they can drop to a 4.

LS3 is not fitted to any VE SSV's.
They use an L76 AFM motor in auto versions, and an L98 in manual versions.
Slightly different motors, slightly different outputs.

[surfwagon]

The LS3 is fitted to HSV VE's late series I and series 2's rated @317kw with 325kw in the new E2 GTS.
The LS2 in the early HSV VE was rated at 307kw.

[PC12]

Whats the difference then between the LS2 6LT and the L76 AFM 6LT. They are both 6lt Chevs aren.t they.

I was told a K&N fliter adds a few Kilowatts for Jam. Any truth.

There would be gains from filters but i dont think it would be very substantial..

ive heard the l98 is the best of the 6l bunch as it has the best flowing heads. even better than the ls2 which is why it was quickly replaced by the ls3 in hsv's

The heads part might be true but the reason for the changeover to the LS3 is that the LS2 went out of production and stock of the engine was starting to dry up. "Planned obsolescence" I think is the term.

No doubt that was planned for by Holden/HSV though.

[surfwagon]

L98 and LS3 heads are almost the same with the LS3 heads having lighter vavles (of the same size) and mild performance springs and camshaft .
The LS2 uses similar heads to the LS1 again with lighter valves and mild performace springs and camshaft.
What the LS2 has over the others is a higher compression ratio.
If you fit L98/LS3 heads & intake to a LS2 you loose some compression but gain extra air flow.
Changing to a performace cam on an L98 will gain more than doing the same on a LS2 because of the heads.

PC12....Hope you're enjoying your GTO.
I'll give you another bit of "trivia" on your GTO's power ouput.
HSV's stated power output for the LS2 engine in your GTO is 297 KW, measured on the SAE scale, and if you look at the HSV brochure relative to your car, you will see that figure quoted, but after it, in brackets, you will see the figure of 305KW (DIN), which is the figure used by many other manufacturers, including FPV.
From VE onwards, HSV actually used the DIN figure when quoting their power output, ie 307KW (DIN) for the 6 litre VE GTS.
HSV toted a 10KW power increase from VZ to VE, but in actual fact it was only 2KW (DIN), because the VZs output was 305KW DIN, and the VEs was 307.
I think the main reason why HSV changed to the DIN measurement was because that was the method used by FPV, & changing to this method enabled them to quote a higher power output than FPV.
Cheers, Pickles.

Hi Pickles,

I just love driving this car. I didn,t intend to drive it much, only the weekends but i find myself wanting to take it out after work for a cruise. She will sit in the shed for 5 weeks soon as a work trip is coming up.

You would have a copy of the sales brochure for them that I could get a photo copy off.

Cheers

What Pickles said is exactly correct, it is on the HSV website when you look at their older models.
Check it out in the specs sheet.

Yes, the VZ GTO is indeed a mighty car. We've just got back from Adelaide, 1800+ K round trip, & averaged 10.26L/100K, or 27.83MPG if you're an old guy like me...and that's at 100/110 KPH with the air on.....not bad for a 6 Litre engine I thought.
I don't have a P/Copier, but have tried to p/copy before, but it doesn't come out too well. Another member has shown HSV website details which you could down load. However, what you need is an ORIGINAL HSV Catalogue for either 2005 or 2006, whichever your car is. They're basically similar, except that the 2006 version does not include the Coupe 4. I'd get a copy of both if I were you.....they regularly appear on Ebay, or maybe a forum member reading this may be able to sell you one.
You may be also interested to know that the new book "Monaro Magic" is to be released within the next month or so, so being a GTO owner, I'd keep an eye out for it. Our car is actually the VZ GTO used in this publication!!
Cheers, Pickles.

Pickles,
Checked out the links that Surfwagon put up. Interesting reading. Would like to know more about the adjustable suspension.

I can go and dissapoint my mate who has the new SSV ute that they are not the same motor.

Highway fuel economy is pretty good for a big car. I did Newcastle to brisbane and had it down to 9.5 at 100KPH. 110KPH averaged 10.4. Around town she is averaging 12.6 at the moment. Thirsty compared to my daily drive Daihatsu. 6 to 7 Lt per Hundred. But then again it does the 1/4 mile in 1 minute.:)

HSV's adjustable suspension (level ride) is crap it was the first thing I removed from my Senator and fitted Poly Airbags and decent shocks instead.
The springs are supposed to carry the weight of the vehicle whilst the shocks control how fast the springs move up and down.
But in the ride level system the extra weight of the vehicle is borne on the shock mount.
When I first got my Senator it had this bad rattle over bumps which turned out to be the shock pounding into the body mount because the rubber was gone.
When I replaced the air shock with high performance units and fitted poly air bags the car actually sat 10-15mm lower telling me that the car had been riding on the shocks and not the springs for quite a while.
The car handles so much better now and when i carry load I just pump up the bags either with a bike pump or at the servo.

surfwagon has said it for me!!. The "adjustable" (Ohlins) suspension quoted on that HSV page is indeed rubbish. They couldn't get rid of them....they offered them at a 50% discount on the last of the GTOs.....just something else to go wrong I thought.
Cheers, Pickles.

[PC12]

What was adjustable on them and How would I know if mine had this crap set up.

Posted a pick of mine in the Coupe gallery after building up the posts. Just a great looking car.

You'd know because you'd have a couple of large cylinders at the rear of your engine bay-----I think they were a metallic gold in colour & had HSV/OHLINS written on them.

Sorry for my misinterpretation, I thought you were talking the rear level ride suspension.
As Pickles said the Ohlins adjustable suspension was offered as an extra on the GTO.
It was fitted as standard to the GTS I believe.
And indeed you would know if you had it because there would be those 2 gold coloured cannisters attached to the strut brace and a switch in the cabin with normal, sport and race adjustablity.
The adjustabilty is when set on each setting it automatically adjusts the rebound and bounce settings of your shocks and also allows more oil in the system for better cooling.

I had a look., nothing there. Must have the standard suspension.
