Best 8 Cyl...BAR HONDA V8 engine (beats **** out of me its prodcution number is)
Geez who did the work for him? My brother's old AU XR8 pumped out around 350kw at the wheels with a basic vortech setup and had a ****load of torque. Nowhere near 30k was spent on that car. Fair enough your mates motor didn't make as many 'kw per litre', doesn't really mean ****, torque wins races, peak kw sells new cars;)Quote:

LS2 is the new v8's in the new range of HSV's etc, 6.0 litre ;)Quote:

It's a pity many Australian's fall into the same category who say "it's the best because it's Australian" but is actually 100% USA export quality.Quote:

In the end though it's all about money and LS engines are the most affordable.:)
this arguement is pointless because there will always be ppl out there who will always say the LS2 is the greatest engine ever built, and that is because they are narrow minded holden loving **%$#@, but thats another thread!
point is even if this thread said "the best V8 in a aussie car" i think the BOSS motor would sh*t all over the LS2, but thats just my opinion, to me the BA GT feels a hell of a lot gruntier, smoother, and sounds 1000 times better than any other 'aussie' car ive driven.
I agree somewhat with the two above posts. I don't think the LS1 and LS2 are the best V8 motors in the world, but they are still a good motor. I'd pick probably the bmw v8's or some other european motor like the Audi. The reason the LS1 has so much support is because it is an affordable motor that has the ability to produc insane amounts of power and it's the same with all old school v8s ie big block hemi's, gm and fords. Look at MRMAD for example, Brodix alloy tall block, capacity of 441ci, twin turbo, 2000hp. How many new V8 motors do you see being modified besides the LS1? Not many, if any;) As for Japanese ' hi tech':rolleyes: V8's, aftermarket support? Manufacturer support? Hmmm don't think either exist much in Australia..
LS2 is the 6.0L V8 from GM used in the Corvette.Quote:

Boss V8 is a good step in introducing newer technologies to large capacity V8s. But, did you notice that the redline of the Boss V8 is even lower than an LS1 pushrod V8? Even the Boss has only a 9.5:1 compression ratio compared to the Holden's 10.5:1. I'm not saying that the Boss is a bad engine. no way. It's making 500Nm out of 5.4L while LS1 is only making 470Nm out of a larger 5.7L. It is a good engine, but I'd prefer to see Ford trying to push the boundaries and take full advantage of DOHC like what Honda has done.Quote:

The power output of the Boss V8 is attainable using pushrods, while at the same time keeping the engine lighter, cheaper, less parasitic loss from the valvetrain and flatter to fit lower cars (LS1 does not need a bulge in the bonnet, but Boss V8 does).
OHV and OHC are both old designs (is does not make them worse). Some technologies are not worth the trouble, look at the many sacrifices you have to put up with having more complex engines. The LS engines have many positive features, that I have pointed out. So far many here have only put forward the arguement of displacement to power ratio.Quote:
Well, I know these engines can make big power
But really... they are sh!t...
Pushrods? Geez we are in the 21st century!
Not only that, but poor head design, piston/conrod design, crank and how it is bolted is all inferior to anything else in the world more or less.
And do not tell me you haven't seen a new holden on the side of the road with it's bonnet up. Because I certainly have on numerous occassions.
They are simply unreliable, unsophisticated, primitive engines.
A friend had a fully worked, built supercharged 5.7L ute, and it still made less kw per litre than my car... when it wasn't even working properly with a stock engine! Fair enough he was only running 6psi and had pulley's for 12+ but this is an engine with about 30K spent on it
As for bad head, conrod, crank and how its put together, tell me why how these engines can pull out massive hp along with excellent fuel economy (for the power)..........look at the bigger 6.0L engine being more effecient and environmentally friendly than the 5.7L.
The engine and tranny of top v8 holdens are actually very stout, holdens use a similar tranny to the vette and also the viper (both in the supercar class).
To answer another one of your questions yes I have seen plenty of holdens at the side of the road, however in their defence there are far more holdens out there that have huge hp and also running very high number of km's. In an equal ratio I have seen fan for jap and european cars on the side of the road, than I have holdens. I would put my trust in a holden when going out to the outback or over long distances than any toyota or nissans (this is coming from a current nissan x2 owner). My experiences with holdens have been possitive, im also guessing that many trust holdens reliability (since there are many people driving holdens).
Finally this kw per litre arguement is not a very good arguement, what is the point for it. Its power and/or fuel economy that im interested in. I do agree that smaller engines have their purposes in europe and also in japan, where they limit the capacities. However we are not europe or japan. Unlike europe america never guaged their economy on engine size but on the actual fuel consumed per # of miles, this in my view is a better indicator of effeciency.
Ok let put it this way how easy is it to get 700hp RELIABLY out of your engine and get the same fuel economy (prior to mods i.e. STOCK) when driving in a sedate manner, with only 30k in the kitty litter..................my guess is not very easy if not impossible.Quote:

Ive never said that LSx are the best engines, but they are befinately one of the best. Many here bag them for being pushrod or have the perception that they are low tech and cr@p, this I dont agree with. As for being narrow minded (hopefully it wasnt directed at me) because my current cars include 2 nissans, 1 ford and 1 holden. I love my nissan (especially my 300zxTT) but would not rate them as being more reliable than my trusty ford and holden. Dont get me wrong maintained properly nissans and jap cars run fine but when not maintained proplerly (or even maintained) I find holdens/ford to be more reliable.Quote:

With newer cars not the problem is not mechanical reliability its electrical/signal, this is one of the pitfalls of a complex engine. Just have a look at BMWs and MB's reliability especially when it comes to electical stuff..............not very good!!!!
Well said monaroCountry. Anyone who has driven a 500hp V8 will know how awesome it is. Bang for buck + reliable = V8;) Before everyone starts up with saying their not reliable, turbo a Honda, Nissan, Toyota, Anything and see how reliable it is for the cash you spend and th power it makes;) Just as a point of interest, I know people with all different kinds of cars ranging from na hondas to supercharged and turbo V8s and so far the cars that are the quickest for the least dollars, while still staying reliable with decent fuel comsumption, are the modded na v8s;) Mate of mine has an ss that does low 12s na, simple mods and has better fuel economy than my adventra (totally stock ls1) and probably even my civic lolQuote:
