There is more to it though than just the name and how it looks, which is what these guys are saying...

I gotta agree with these guys - definitely not related to the Impala. Just because it looks similar doesn't make it the same car - that's like calling an old turn of the century Sebring a Camaro because it looks similar. Not at all the same car, and just as the Camaro owner would take offense, so should an SS owner if somebody called his car an Impala.

Ok, before this thread gets totally derailed with all the talk of heavily modifying a 3.5, can we please keep this an LS4 Performance-specific thread please??? Not trying to steal your thunder or push you out Whoaweezy, but try and keep your specific stuff to its related thread(s), start a new thread specific to your build for others to follow, or section of the forum. This IS the section for the 5.3L LS4 bro...

And now to get back onto the topic of LS4 performance: a few days after Christmas, someone on the LS4Nation page on Facebook had made a rather shocking discovery regarding an LS4 powered car - an '05 Pontiac Grand Prix GXP that was for sale on Craigslist in the Battle Creek area of Michigan.

Now for the last year or so, a lot of the LS4 guys have been wondering about doing a supercharger on the LS4, with no real answers or possible outcomes. Not the right kind of system, no real room to fit, etc., etc... Now what this one person discovered about this particular GP GXP, was exactly that... This car had a supercharger on it!!! It is an actual GM unit, but it was custom made for the LS4 application using 2 main components from 2 different GM superchargers, along with a custom snout for the throttle body and a new drive pulley to be used in the rear for the LS4. But it has been done, and I wanted to share this with you guys.

Now be forewarned, this is NOT a readily available unit for these cars, it was custom made, and it is more than likely going to cost as much as - if not MORE than a turbo kit for the LS4... But for those of you who are interested in the details, follow this thread, or the thread I am going to make specifically for this topic. This post in this thread will be for the general thoughts on it. More specific thiughts, comments and whatnot should be posted in the specific thread for it...

So ladies and gentlemen, a present to you, a little taste of what a supercharged LS4 is... Anyone care to guess what the 2 main parts to the supercharger itself are, or where they came from???

Was that directed at me bro??? If so, no need to be a douche about it. I am not trying to be one to or towards you, or your idea or what you want to do for your build... I honestly think that what you are trying to do for your drive train is a great idea. Being a pioneer for something major for that motor is great, and I think you will get a good following for it if it all works out. And just so you know, I am actually following your thread and progress to see how it all comes out.

However, you are dealing with the 3.5L V6. It is nowhere near the same set-up, internals or anything to the LS4. I see what you are doing, and trying to base your ideas off how the turbo kit on the LS4 would apply to the 3.5L, but asking specific details about your internals and stuff should be done in the main 8th Gen Engine Performance section, or start your own thread for it. Asking about which internals and stuff you will need for your 3.5 in the section for the 5.3L LS4 guys is derailing the thread for the rest of those interested in the specifics for the LS4.

And further more, I personally don't know anything about the 3.5L, as it is not my current platform of engine. If I DID know, then I would reply directly to your thread about your build, and tell you the answers in which you seek.

Again, I am NOT trying to be an asshole about the whole thing, just merely asking you to please keep your specific questions regarding your motor out of the LS4 thread. I have NO problem with you, or that you are trying to get ideas from how the LS4 turbo system is run and piped for you to help get your build off the ground. Like I said earlier, it is awesome that you are pioneering something new for your platform. But I personally don't know the 3.5L like I do the 5.3L. So therefore, all the speak of the 3.5L is basically Greek to me.
