VE could be 5.3 with DOD

Holden has two choices for V-8s: the 400-horsepower, 6.0-liter LS2 currently in the Monaro and the high-performance Commodores built by its AMG-style in-house hot shop, Holden Special Vehicles, or the all-aluminum 303-horse, 5.3-liter L33 engine that sees duty in the new Impala SS and Pontiac Grand Prix GXP. Our sources in Australia are hinting that Holden will opt for the L33 engine for regular V-8 Commodores to ensure good fuel consumption and save the LS2 for the new Monaro and the HSV cars. Transmission choice will be either a six-speed manual or the smooth new six-speed auto that first appeared in the Cadillac STS-v

Seems unlikely to me. The L33 is an FWD engine (both the Impala and Grand Prix are FWD). If they got a smaller V8, Cadillac's 4.4 or 4.6 Northstar would be a more likely candidate methinks.

I'm not bagging you here Steffo, but it wouldn't be the first time Holdump put a FWD engine into a commode.

yeah the 3.8 V6 Buick motor was FWD wasnt it ?

chevypower · 31-08-2005, 11:49 AM

LOL motors are just motors, they are not FWD or RWD, neither LHD or RHD they are just motors, but yes the 3.8 and supercharged 3.8 were in FWD Buicks

It came from the Buick Regal (RWD) and Chevrolet Camaro V6/Pontiac Trans Am V6 (RWD). The FWD-application variant of the 3.8 (L67) never made it to Commodore... the engine we got was L something else.. L32 I think.. something like that.

Do your research a bit better than that Steffo. The L33 is also used in RWD and AWD platforms like the Silverado / GMC Sierra and is available in a range of outputs.

I thought that was the LM7... ?

WASP · 27-08-2005, 11:50 PM

With that Mooney character controling things anything is possible. To be honest, at the horror of most Holden fans I actually think the idea has some merit. Then again I am not that familar with the L33 engine.

See, I'm not sure if the L33 is a Gen IV or not. The LM7 as was in the Silverado/Sierra was a Gen III. It was basically a smaller LS1. LS1 heads and cams fit in the LM7, but it sported a smaller bore and stroke and some other minor differences... it also displaces 5.3litres.

The Vortec 5300 and 6000 in the trucks have a cast iron block and aluminium heads and 5300 is supposed to be E85 compatible (which is a better feature than DOD), but I think all Holden V8s should use Ls2, with E85 compatibility

Correct - the 5300 (LM7) and 6000 (LQ9) are the standard engines but the alloy 5300 (L33) is an option in SWB performance variants of the two I mentioned above.

I drove a Chev Trailblazer with genIV Votec 5.3 V8 last October in the states & the performance in acceleration & fuel consumption was not the greatest.
But one thing it would sit all day at 90mph.
Not sure if its the way to go for Australian performance Holdens.

Dave_au · 28-08-2005, 02:35 AM

Problem is our domestic magazine sources have been hinting at the ls2, not the 5.3. Additionally, the article makes reference to the new Monaro, therefore it isn't that acurate.

CSV_LS1 · 28-08-2005, 03:51 AM

I was told a long while back that holden will go for the 5.3. Wasn't too sure back then but now i'am a believer.

The Stylist · 28-08-2005, 09:14 AM

I think the 5.3L makes good marketing sense for the regular Holden's and especially since the price of fuel is going up and up. I'm not saying the 6L is a gas guzzler - as I don't know, but from a psychological point of view a smaller capacity number in the average public mind equals lower fuel consumption.

I guess what I'm saying is that for the un-educated (techno-wise) a smaller number sounds better.

Sorry if I haven't communicated my rather irrelevant left-field point of view to well - someone hid the coffee container this morning.

4Vman · 28-08-2005, 10:43 AM

Im hearing that HSV aren't too keen on letting Holden use the LS2 in the std V8 cars, so this makes sense.
Their feelings are that the performance difference between the SS and clubsport was too close with Gen 3.

Cobra · 28-08-2005, 01:15 PM

So what kind of power are we talking about with this motor? Is it an OHC or pushrod engine? If Holden used it in all their regular cars, would it be a possible replacement for the LS1 in an SS? HSV want to keep the Gen IV to themselves, but Holden would need an alterative that would offer them enough flexibility for many upgrades in years to come.

I would love if Ford kept 5.4L for the Ford range and has a 6 litre all alloy quad cam V8 for the FPV range.

Lukeyson · 28-08-2005, 03:18 PM

wonder if it does end up being the motor in the VE, whether they will do a factory turbo/supercharged model ?

I dont think that HSV is up to being compared with AMG. And for that matter neither FPV. Hmmmm AMG E55 or SLK500.

ssj_jaypee · 28-08-2005, 07:24 PM

Doesnt make any sense at all.
Why would Holden go backwards? 5.7 > 5.3
This would be a blow to its fanbase.
Plus the LS2 is getting some kind of efficiency technology which enables it to change from 4 to 8 cylinders on the go right?

Displacement on Demand, or DOD. It's mentioned in the thread title.

ssj_jaypee · 28-08-2005, 09:02 PM

The LS2 is more fuel efficient than the LS1 from what I've heard anyway.
VE commodores are gonna be heavy pigs with all that new technology, so why go with less power?
Still makes no sense.

Holden might not see it as a backward step, LS1 isn't emission compliant to the new rules, LS2 is a HSV motor.
Not eveyone is infatuated with capacity numbers...
With fuel prices soaring and the focus turning more and more towards fuel economy, emissions standards and safety id expect the car manufacturers to start looking it other ways to sell cars other than capacity and KW figures..

**Charliewool** · 28-08-2005, 09:28 PM

Ummmmm, WHICH "new" Monaro??..I thought end of the road for Monaro, crewman, one tonner etc?.........

29-08-2005, 09:17 AM

Engine capcity for road cars has to stop somewhere so I don't see it as a backwards step either. 6.0l is great for a HSV but on a Calais or Statesman/ Caprice? It wouldn't sit well with buyers.

Thats correct, looking back on history Ford went from 220KW in 1973 to 150KW in 1982 with the 351 cleveland after the ADR27a came in and fuel prices soared.
Then we went from 351 (5.8) to 302 (5.0) after the cleveland was dropped for the windsor.
Times are changing again, maybe were about to go through the next wave of battling fuel prices, ever tightening polution regulations and stringent safety standards.
5.0 or 5.3 or 5.4 is still a large capacity motor.

OzJavelin · 29-08-2005, 12:05 PM

As I responded to the same thread on the LS1 forum .. I'd be happy with a 5.3L V8. In fact I'd be happy with a 4.0L V8 is they (Holden or Ford) has a light enough car for it to be put in .. not the 1700-1800kg barges we have now.

Yeah and they would be great if they were actually high performance.
I wouldnt mind if Holden even came out with a 4 litre V8 if it had the technology to produce 400hp from it.

chevypower · 29-08-2005, 02:06 PM

whats the use in a 4 litre V8 producing 400HP? I think 6 litre V8s would be nice in the Statesman and Caprice, a lot of lwb luxury cars have 6 litre engines, Audi A8 W12, BMW 760Li, Merc S600L, I'm sure the Holden 6 litre when fed through a 6 speed auto will be able to be fairly good on the fuel. The fact is less cylinder displacement with the same output in the same car, does not equal better economy
