Default We want change...

We might not be able to change the world... BUT... We might be able to Rock GM's World a little bit. I don't know about you but I am mad that GM is not supporting the LS4 Group of vehicles.

So... I say we start a letter campagian and get them to start paying attention.

Look, Mr. GM, I feel put off by the lack of support you are showing the LS4 vehicles and while I have been a faithful GM buyer... I may have to go to a brand that better supports their vehicles like Ford, and Dodge. I bought an SS model because at one time that meant something. It meant GM was going to flood the market with product, and/or lend support to aftermarket companies to produce products for their SS models. The LS4 group is NOT being supported and it is a crying shame. Blah, blah, blah... better wording, grammer, etc.

But we need to wake them up to the fact that there are enough LS4 owners (with money), that they need to step up to the plate or risk losing their future business.

I will find the address to their Marketing, Executive Offices. One letter marked in bold letters "WE WANT SUPPORT", may not mean anything, but if they suddenly get 100s it will draw their attention. What do you say?

I agree and I'm for it, but don't know if it'll matter at all... seeing as how they didn't even advertise these new Monte SS's at ALL.... I never saw ONE commercial advertising the Monte SS....

the only way I even found out about it was browsing chevrolet.com's site.... nothing on TV, nothing in print, etc etc...

Is it really GM's fault though or is it the aftermarket companies?

It's all profit for them and they make products for cars that sell better. Do you think DS would have waited this long to come out with tranny support for the new Mustang?

Just wait and see. Since the First LS4 came out in 2005 in the GXP and they will still put the LS4 in the 08 Impala and GXP, you will start to see more aftermarket items for them, but it will take time. The biggest news is headers from Milzy Motor Sports, as I am still working with Mike since I am the only one willing to pony up with him to get this started, yet its going to be awhile on the build and before I can get out there to see him. Also, look for bigger things from Milzy Motor Sports as they will be going into the LS4 aftermarket soon.

SS_Black_Attack,

I'm not sure what you are wanting. There is a turbo kit that is just being released to market. Headers will come sooner or later (in fact you could probably get a set made now if you want to put a little money in). Fairly reasonable cams from LSx motors will work. Rockers have been installed. Intake manifold could use some work and hasn't been addressed at this point. Alot of the current LSx internal parts will work.

In fact, I'm guessing there are enough parts available to break the tranny several times. And of course, the parts are there to fix the tranny.

My point is, you may need to state what you need by support. I think you would have alot more success with your campaign.

Chip

There are several high-performance mods right now, but you will need to throw money at the mod itself followed by the tranny and other suspension stuff you will nuke. It's not GM's fault, and they are ending production of the FWD w-body, we have begged for parts before....sadly its not happening for us until someone like Jay throws money at an adaptable (read: starts as one-off custom) turbo|cam|etc....

It isn't up to GM to support the aftermarket, maybe they needed to do that in the past but certainly not anymore.

There are lots of parts available, you just have to decide what you are looking to do.

Am looking for support, like they support all the other LSx. When I go to GM Performance or Semac, I want to be able to see and buy a Crate Motor (Turn-Key) LS4 (Injected, Enderle hat, Supercharged, Carberator, highrise, etc.), cams, cranks, super high volume oil, etc. I want to see HD Transmissions, suspension systems, etc, like they have for all the other LSx.

And no you cannot use the crank or cam or most other parts from the LSx family. I believe it is on one of the Stickys on this site that talks about the LS4 being a VERY UNIQUE motor because it was based on the LS6, but they had to modify it to turn it sideways -- such as making the cam, crank, block shorter (12mm to 18mm??). So a LS6 cam is not slipping into an LS4. So everything is a little different in the LS4. Ok, you could possibly use the same lifters and springs... maybe.

I want GM to step up to the plate! They designed this thing and the SS trim level in the past meant it was going to be supported fully my GM and GM Performance Group. The thing is, they made it FWD! Who uses a FWD in auto racing. It is simply easier, cheaper, and effecient to maintain a RWD race. So by their own design we GET SCREWED!

Yeah I agree there is a good amount of aftermarket that's finally starting to trickle out from 3rd party sources. But I also agree with the OP in that it would be nice to see some authentic GM aftermarket. For example, it would have been nice to see "stage" treatment like they gave th cobalt. This way someone could "mod" their car while staying under warranty.

No offense to cobalt drivers, as their cars are decent, but why does the domestic "rice" solution get special treatment? Well I know why...because cobalts are much more popular...more of a rhetorical question. You'd just think that american "muscle" would get such attention. Nevertheless...maybe you if you actually advertised monte's.....eh....nevermind. Stupid GM.

Why I'm even considering another GM (G8) is beyond me. At least they're doing something right by bringing over some stick RWD love. I'm just pissed that they're one generation too late. An '06 monte with RWD and stick (or even auto) is my dream car.

Wow, you guys are funny...lol

I bet even if there was something available from GM, it would be too expensive and you would just go aftermarket anyways.

I had thought the obvious reason would be, well....obvious, guess not.

GM already limits torque and power in the drivetrain (likely for durability reasons), why would they offer accessories that increase that power? They would lose more in warranty work then gained in profit from the sales if the drivetrain is not robust to take the power that an unrestricted engine would produce, besides the LS4 cars are not meant to be the boy-racer-specials. Most people who own one are like me, wanted a middle-of-the-road cost, decently powered car that can be driven in the snow. The younger crowd that prizes speed above refinement (and who does not as of yet bring in the big paychecks) are more likely to buy cheaper cars and upgrade them depending on how much tip money they get from delivering pizza that week.

I bet you're wrong! I bet, if GM produced it, I would buy it from them rather than an aftermarket company -- unless is was a well-known, well respected company like Edelbrock, Holley, TRW, etc.

Jack Roush rebuilt my Mustang's Motor & trans, and it took me almost a year to pay him off. Wayne Motors did the suspension & rearend. I promise you... the price tag - wasn't cheap.

Well, the OP did not specifically mention power adders....he said support...which could mean a lot of things.

What you say about cobalts vs montes makes sense...I was just ranting. The fact of the matter is....if they built an SS the way it SHOULD have been built, it'd be capable of safely adding additional power.

I'm actually very impressed with the performance of my car. All stock I ran high 13's and this was with a 2.0 60ft time and a cocked air box tube. Surely I can do better that, but my car surprised a lot of people that day, and keep in mind that this is a daily driver!
Now.. my only complaint is that the trans is not aggressive enough and the 2nd to 3rd shift is a joke. Also, I wish GM would have given us some kind of a performance
button for the trans like the older GTP's had. This is what Tapshit mode should have been used for since it does practically nothing!
It pisses me off that the 5.3 truck motors are rated at 315hp what gives? I think the drive train is plenty of strong and should be good for 400hp.
Now.. If you guy's want support then buy a Mustang, I test drove a GT and I wasn't all that impressed. With 3.55's 3rd to 4th felt like a real dog and traction wasn't all that good either. The interior wasn't all that exciting but I did like the insterment cluster, but the GXP's is much more exciting! RWD is where it's at and always will be.
At least GM gave us a V8! Don't we have one of the highest HP rated FWD's?

Go back and read the stickies. The design is based on an LS2 not the LS6. The crank is the only part that is shorter. It is shorter on the nose and the flexplate mount. These could be machined on a stroker crankshaft since we are only talking a few millimeters. The cam is the same length, so any other "reasonable" LSx cam will fit including the one from the LS6. The most important thing is to keep the lift at the valve under .590". The accessory drive is the most unique part of the LS4, but would only be a potential problem if you are trying to use a supercharger. The only things to be addressed is headers and intake manifold. And believe the headers will be addressed before too much longer. Also, as mentioned in the sticky, our oil pump flows 31% more oil than an LS2 pump.

GM has a "cookbook" out that shows what to do to beef up the trans. As mentioned before, there are W-bodys with this same style trans (different case, same style internals) running quite a bit of horsepower (10's and 9's in the quarter).

And I guess in a way, they are fixing the FWD problem. 2008, 2009, and 2010 will bring out the Zeta cars (G8, Camaro, and RWD Impala).
