View Full Version : L76 bolt-ons...how long til they are avail.??


BEWARE

Just curious if anyone would know how long after the 6.0L commo's come out will bolt ons be available.

Like headers, exhaust systems, CAI's, edits etc etc or is some LS1/2 stuff going to be compatible??

I'm going to be keen to get some performance mods done to mine quickly(like ones listed above)....and don't want to be waiting for months until shops get this stuff out!!!

Thanks
Michael

I would think that most bolt-ons that fit the LS1/LS2 would 'bolt straight on' to the L76. The edit/tune I'm not so sure about however I think a sponsor or two has indicated that they are L76 tune ready.

Cheers

I would've thought the the L76 PCM would be the same breed as the LS2. So I'd assume that if a tuner can tune an LS2 they can tune the L76.

For the VZ's the exhausts that fit an LS1 will fit too. Not sure about MAF pipes and such. I noticed that there is a resonator on the intake too!

It's a ready made market, so if existing bolt on stuff won't fit them, new lines will be in development. There is no correct answer for your question though, as different companies will take whatever the time is to develop and release products. You would have to ring many places to find their release times to get your answer....

Since both the L76 and LS2 engines are both Gen 4, from what I have read the main difference in terms of performance of the L76 and the LS2 is the different heads, so presumably you could bolt on the better breathing LS2 Heads to the L76 Block, Just a thought bubble, cheers Matthew

From what I have read the L76 heads are a further improvement/development on the LS2 heads, so I doubt you are gunna want to swap em.

LS2 heads will loose you power on a L76 which has LS7 style heads. Tuning a L76 is only a few weeks/month away and they use a differant PCM to the LS2. Holden have had to work hard to lower the power in the L76's (took 3 cam changes to get the power low enough) so swapping that out and putting in something decent, a tune and free flowing exhaust will see 300+ rwkw. From discussions with workshops the L76 is going to be a better engine to have than the LS2.

Only time will tell though.

LOL.. like i said, time will tell. I do see a few HSV owners being pissed off though.

Dont forget the LS2 and L76 we put in the cars here isnt 100% the same as the US. We use differant cams, tunes and gearing. The L76 heads have the same 12 degree valves as the LS7 and are the same size as the LS2. The intake manifolds are the same part numbers but looking at the heads side by side the L76 will flow much better. Its the cam that will hold it back in its "factory form". I dont proclaim to be an expert but when a workshop that ARE experts tell me the L76 is going to be better i believe them. They havent been wrong in the past.

Look what the L76 was designed for. Torque. How is that a bad thing?

Pure Bulls*** Stu. There is no such thing as the L76 in the States.They have the 6.2 which is 4.04" in the bore. What we effectively have is the 6.2 litre head on the LS2 short motor. The heads have non cathedral style ports and 2.160" intakes standard....no LS2 has this size. There is no simularity between the intakes apart from the 90tb on the front. Don't know where you are getting your stuff from but it is off with the pixxies. One thing for sure though....you started out ok when you said the L76 head was better than the LS6/2.

All standard exhaust etc that we have used over the years will bolt straight on. so same old same old. Reckon it will be some time before we have programming though. So to shortcut the development Iam bolting a set with cam onto a LS2 Maloo next month.

HSVDKB, there is no way known you went the wrong way with a LS2 HSV. Sorry mate, but you bought yourself a great car.

The fact that the L76 has potential is great, but it isn't the be all and end all. You have an exclusive car in the VZ HSV and there is plenty of potential, should you wish to modify.

Unfortunately (fortunately?), the car manufacturers always do bigger and better on the new model, or otherwise people wouldn't change over to new cars.

Remember the change from Holden 5.0/5.7 engine to the LS1 in the VT2. People were screaming at how it devalued their VT HSvs etc, but that is progress. (Mind you, I still reckon the stroked Holden engine is a pearler!)

As long as YOU are happy with your rig, then be happy.

Macca

ummm....the 6.2l will be std later year and the SC derivitive isn't far behind from what I hear in the 'Vette. What hsv will do is anyones guess but I would reckon they will need atleast the 6.2l (400hp) to try and get some sales away from the SS. 6l Club....? Not real exclusive is it?

Thanks Macca, more than happy with the current rig, but if the guys are right I guess it maybe opens up a cost effective replacement vehicle when the time comes. Maybe a VE SS with a cam to unleash the L76 potential.

The intake info came from Holden part numbers. The valves on the L76 and the LS2 are also the same part numbers. I was under the impression the L76 was based on the truck engines but you would know more than me in that regard.

Sorry for the misinformation. Its what i was given by Holden (who don't know themselves at times) Ill check those part numbers again.

Basicly what your saying is the L76 IS a LS2 with better heads, a shit cam and a different PCM.

I can see this creating a huge debate. This is almost going to be as bad as the ford debate of which motor is better the 3 valve or the quad cam?
As for which one will be the better motor, the LS2 will always be sold as the premium engine and with 47kw more off the floor it will be that way for the majority of buyers. If the L76 has more potential then this will become the tuners choice.
BTW if the L76 heads are really that good it doesnt sound like there would be much effort in bolting these onto an LS2 block anyway.

I just checked the part numbers for the LS2 and L76 bare blocks and they are the same part number (12568950).

This fact will actually solve all the arguments, not matter if you have an LS2 or L76 Block, everything else can be swapped around to come up with the best package.

What would be interesting to explore on this thread would be working out what parts are the same and what is diiferent, so far from what I have read the block and inlet manifold are the same, so this raises a few points regarding block internals which should theoretically be interchangable:

Which has the better Crank, Pistons, Con-rods, Oil Pump etc, etc, etc?

Since the bare blocks are the same does this mean that DoD can be fitted to the LS2 when it also becomes available to the L76, or will the L76 block that Holden uses change for DoD. Cheers, Matthew

Interesting Q Matthew. I understand that the the DOD and/or VVT require some different oil galleries, and therefore when/if the Australian L76 gets them, the block may change to suit. I don't think the block casting will differ but may have some additional gallery machining. The story for us not getting VVT at this stage is that it requires additionl space at the rear of the heads which is not available in the current bodies.

someone said that between the ls2 and L76 that there was a different pcm, so, if what i have gathered so far, throw a (non restrictive) better cam in L76 and a tune and she will be a bigger animal because of the better heads than a Ls2 , just wondering what is the difference between the pcm?? does the ls2 have a faster scanning potential ie is it faster to make changes to timing and fuel curves etc? or is the L76 pcm better, maybe that could be a potential swap?

Sorry to disturb the mini debate here which I have come to love, but as the thread topic started out as, I am keen to find out what bolt on mods are available for the L76. I have just ordered an SV8 and I am wondering if the first step would be to adapt an LS2 intake to the L76. The L76 has a large intake noise reducer not unlike the EL series falcons had, and it also has a longer maf sensor than the LS2, which means the maf pipe will not be a straight swap between the two engines which both have 90mm throttle bodies. A bit of cutting and shutting of maf pipes will no doubt improve the L76's intake issues but I am just wondering if anyone has performed this mod yet?

No such thing as L76? That'll be news to Chevvy, who is selling them in the just-released 2007 Tahoe.

From this article:

http://www.gminsidenews.com/forums/showthread.php?t=20160

Gen IV small-block details

The Gen IV Vortec V-8 truck engines are built in a variety displacement and power combinations, including versions with aluminum cylinder blocks....

6.0L aluminum block (L76) with Displacement On Demand technology and variable valve timing, rated at 355 horsepower (264 kw)*
6.2L aluminum block (L92) with variable valve timing, capable of 380 to 400 horsepower (283 to 298 kw)*

Revised cylinder block

Aluminum-block Gen IV-design engines debuted as the LS2 in the 2005 Chevy Corvette and SSR, as well as the ’05 Pontiac GTO. The new Vortec truck engines share the basic design of these versions, but are engineered for the specialized needs of truck applications. Like the LS2, the new Vortec engines have a revised cylinder block design that features new, externally mounted knock sensors. They were moved from the valley area to enable Displacement On Demand technology and other advanced systems.

...aluminum blocks are virtually identical to their iron counterparts, including a deep skirt design that incorporates cross-bolted main bearing caps and a structural oil pan. All engines, except the 6.2L L92, use a proven iron crankshaft design and highly durable reciprocating components. The high-performance 6.2L L92 uses a forged steel crankshaft.

The block for the 6.2L engine features a crankcase “windows” – vents that help improve bay-to-bay breathing. This reduces pumping losses and supports the high horsepower output of the high-performance engine. A new, 58X ignition system and a more powerful, E38 ECM are integrated on all engines.

L76 is not detuned - it makes 355hp (264Kw) in the Tahoe. No doubt it could make more but is engineered for that much. The cam and plenum changes are probably more so it passes ADRs - US noise limits and pollution laws are different.

Surely as far as bolt on's go exhausts cats and extractors are straight from LS1 so this is sorted - correct me if I'm wrong (I'm sure I don't need to ask for that in this thread :errr: ).

Also it will be a matter of adapting an OTR to fit or possibly running one of the LS2 ones like the Orssm one Sonny at Marranos will have for sale soon. That takes care of the induction side for a bolt on.

Manifold and TB will surely not be a concern with the size of them OEM and then it's really down to waiting for someone to release edit software which shouldn't be too long :goodtime:

I'd love to bolt on a turbo :banana:

planetdavo: I post what info i have and try and be as accurate as i can. At times im wrong and dont have a problem when ppl like HQ correct it. Fact is there isnt a lot of info on the engines and I posted what ive found which was mostly right. That way everyone learns a bit more. Look at this thread, im sure everyone that reads it now knows more about both the L76 and the LS2 than they did. I know a few ppl on here have agenda's and like to have a shot at ppl, workshops and the dreamers but you just need to ignore them. HQ has always offered good advice and i didnt see his corrections as anything other than positive info.
It's all good then!
My point has always been that this member does not need to abuse people for errors, as he has done many times to many different people. There is a good way AND a bad way to explain corrections.
My last comments on this subject. Hope it's been enjoyable!

looks like chamber to me. i will cc one in the morning but would reckon they will go 70+cc against the ls6 65/66cc. Got to make room for those valves somewhere!

I think the L76 heads have 74cc chamber.

2007 product range

Tahoe is listed as a 5.3 ?


Chevrolet Avalanche
Chevrolet Suburban
GMC Yukon XL
list the new l76

http://media.gm.com/us/powertrain/en/product_services/2007/Spec%20Sheet/Gen%20IV/2007%20Final%20Gen%20IV%20Truck/2007_L76_Truck121505.xls

They are the larger trucks/SUVs which have the L76 as the base - Tahoe uses the iron version of the 5.3 LS4 with DoD as the base, with the other engines optional. As the blocks are all the same externally and dimensions-wise, there is no issue. Same as the old small block went from 265-400 cu.in.

No more mud slinging in here please. If users have issues between themselves - that is what the PM system is for.:whip:

Howquick (although unusually testy in this thread) has a point. If you are quoting from books/PN cd's etc might be a nice little disclaimer to say where the info is sourced from.

I know I do when it comes to HSV gear I get asked questions from.....alot of the model info etc is sourced from HSV books etc etc.

Very few people here post info with the intent of misleading others.....we are all trying to learn, as always someone will always know more!!!

It's when they correct people politely and people recognise their errors in the same manner that we all benefit.;)

Now play nice please!:thumbsup:

Your opinion is noted.:)

The PM system is there for communication between individuals for forum related matters.... regardless of what the context maybe.

Adults should be able to debate and resolve issues/disagreements without it being dragged into otherwise informative threads like this one.

If a member does the right thing and PM's you in an attempt to remove the debate from the public domain, that is a good thing. If you prefer to avoid that individual, simply ignore the PM and avoid further reponses in the thread in question.

I see both points of view here, everyone is trying to contribute, but the internet often is taken as gospel by lesser informed people, so Speed Shop owners have to continually dispel the same rumours and "facts" that people read from the net - every now and then they may get a little tired of it.......

Empathy is the key here........if you wish to continue this discussion feel free to PM me or email hrtstroker@ls1.com.au

What is the overall length of the new Maf ?

I am not sure of the exact measurement, however I would say the actual maf sensor itself would be around 120mm long. It's probably a bit longer than the old pre VZ cast alloy sensors and is about twice as long as the VZ plastic maf's. I'm sure that a suitable intake pipe will be easy to knock up in the shed :headbang:
