LS2 vs L98 vs L76, which is supreme??

[boofsta]

Out of these three motors being all 6 litre, which is best? Ive just joined the 6ltr club an wonder how my LS2 compares to other 6ltrs...

[Vulture]

It depends...

L98/L76 is the same engine except the L98 has the redundant DOD hardware removed.

Conventional wisdom seems to be that the L98/L76 is the superior engine owing to its better L92 heads.

Shouldn't you have worked this out before buying?

Im quite happy with my LS2 whether it be better or not, was just after a comparison of the three...

Seeing the Pontiac G8 has a 6 litre with DOD and maybe Holden will introduce DOD in the future does the L98 revert to being an L76 again?
What are Holden putting in the Pontiac G8 an L76 or an L98 with DOD and still calling it an L98.

standard the ls2 is 297/307kw and the others 260odd nuff said. there you have it! but for modifications etc the story appears very different.

as stated above there are heaps of threads on this with some good info...

didnt know there was an old thread,:confused: searched but couldnt find one hence why i posted this one. i looked at the old ones which made for a good read.

its not the power there tuned to make, the ls2 heads are the worst flowing out, if you line up a ss/ssv and a e series gts the ss makes approx the same amount stock at the wheels(same drivetrain,dyno/day), and there 270 compared to the 307, then as soon as the mods begins as sonny has tested and proven with same cam, bolt ons and tunned the ss l98 made more power and torque and people with the ls2 are wondering whats wrong with the hsv's donk, sonny also did both the cars and mods at the same time in a thread on here so try find it, so best upgrade for and ls2 is putting l98 heads on


LS3 heads on an LS2 :eyes:

Before anyone says anything... LS3 valvetrain is different to L76/L98/L92 :moon:

hmm never knew that, cheers

I am only a dumb engineer so you are going to have to explain how a 307kw motor puts out less kw than a 270kw? I understand that the L76/L98 responds well to mods though..

Only difference is the hollow intake valves which by the way the yanks are saying are no good for FI as they .

[CarlFST60L]

They all make about the same mate, you cant go wrong.

You will find most people that own the L98 will bag the LS2 because it makes them feel all warm and fuzzy inside :stick:

My LS2 made ~240kwrw stock as a rock, 260kwrw with unopened mod's (CAI, tune etc), and 300kwrw with a very small cam and ran 12.43 @ 1950kg @ 32C as driven from the factory (other than power mod's).

Yeah it absolutely shits me that my ls2 makes 318rwkw with a cam. Wish i had an l98. Suicide is my only option......... :soap:

Why the fark do people get so bent out of shape about whose engine makes more power. Its the same old 'my dick is bigger than yours' arguement rehashed. Get over it and move on.

What the? please explain...

[Funky_Munky]

From my research, in standard form, the LS2 is a superior engine to either the L76 or L98. Simply, the L76 / 98, are in the late model VZ SS (making 260 kw) and in the VE SS and VE SSV models (making 280 kw). The VZ and VE HSVs make 297 / 307 kw. I understand that a tune could affect those figures, but you have to assume that HSV have a reason for putting the LS2 in the HSV and the L76 / 98 into the SS range.

However, there seems to be some sort of consensus that the L98 heads do flow a lot better than the LS2 heads which is advantageous when modifying your car beyond just simple bolt ons. A lot of the sponsors are of this opinion and, again, you would have to assume that these guys know the business.

In either case, they are both great engines and I think it will only be a factor of 10 - 15 rwkw when you enter high rwkw territory.

[HYMEY]

The most common mod the yanks do to the LS2 is put L92 heads on and they always make a power gain. The cam choice is more critical with the L92 heads because of the big intake on the 6.0L. Once the Weiand and FAST manifolds are released they will become even more popular.

Some prefer the cathedral heads but those who have nutted out the correct cams to use with L92 heads have reaped the awards.

[ADO_SS]

ls2 seems to be the better engine un-opened. My brothers vz clubby with zorst and maf tune runs 12.5 on everyday street rubber(not et streets)
I have not yet seen that from an exhaust and tune only L98/L76. In sayin that, I have an L76 and could not be happier. You cant really go wrong with any of the 6L engines as far as im concerned:thumbsup:

:idea: The tune, the different exhausts on the 2 diff engines

C'mon, engineers are smarter than that! :stick: The answer is quite simple: the LS2s in the HSVs are a little overstated in their power outputs and the L98s in SSs etc are a little understated in the brochure power outputs compared with reality. One of the major magazines found very little difference between the Holdens and the HSVs at the rear wheels. I would be a bit disappointed but as others have said, L98, L76, LS2 or even the 'old' LS1 can still be made into very fast cars. Let's face it, if you mod then an 11 second car is relatively easy to get with any of these engines and that's nothing to sneeze at.

What nobody has mentioned yet is the issue of drivability. I put a crate L76 into my SS recently and both myself and even Powertorque have been stunned at how drivable it is even with 236/242 cam. An LS1 would almost certainly be more cranky to tune.

[wilsy0001]

i have a ve l98 with cai a zorst and a maf tune and got 259rwkw im verry happy with my l98 and putting a cam in soon

[Pepps]

L98 and L76s are in the VE range right?
What engine is in the MY9.5 VE SS? Is it the same as an 07 or 08 VE SS? I have no idea about these two engines coming from an LS1.

:goodjob: my L98 with a LARGE cam in it makes 303rwkw NA and runs 10.8..........an yes it does make me feel all warm and fuzzy as I exit the track and head home,............... stopping only to pick up my time slip :)

i was under the impression the new ve ss auto had L76 afm and manual has L98

[Pepps]

^^
I read the above also, that the auto has the L76 and the manual has the L98..wasnt sure whether to believe it or not?

[SVNLTR]

Call it whatever you guys want-

You guys know if you got afm or not-

same heads-same casting etc etc

one of the mods better do a sticky on these engines..........

[BlownLS7]

this is correct, L76 in auto with AFM ,L98 in M6

the MY 9.5's L98's have very small differences from the MY/8.0/7.0


as for the LS2 vs L98 who cares, both are capable of 300rwkw with near on same mods.

and 300 rwkw is more than most ever need .and anyone whos not happy with this sort of power needs a happy meal.



cheers paul

Would you mind posting up a time slip for your brothers run mate? That is good going for an unopened car on street rubber!! I'd love to know what sort of 60ft and MPH he got to reel off a time like that. The best unopened i've seen for a l98 would be a 11.8 from GMM, but that was on DR's. Hard to say what it'd do on street tyres.
You are right about the potential of these engines though! They all respond extremely well to mods, or even just tunes. I wouldn't spend too much time worrying about which is superior, just enjoy the power you have.

LS2 would have more power from factory due to bigger HSV headers and exhaust and a more aggressive tune wouldnt it?

Its true what was said above, current VE manuals are L98's and auto afm are L76's :)

[stu-k]

L76 is obviously the pick, cause now i know thats what i got :D
