No, those are saying that the con rods can WITHSTAND up to 800-1200 Hp. Besides, you are looking at about $500 for the rods but about $1k+ for the labor (unless your like me, and rip apart the engine). They wont increase Hp, maybe like 10 if they are lightweight.
If you want throttle response, take parts that are heavy and rotate, move, whatever, and buy lighter weight parts. Cam gears, drive shafts, Flywheel, stuff like that. Unless you can do it yourself, add about another 50-70% onto the price of the part for installation.
What else... ah yeah, spark plugs. The best way i know to increase Hp AND Mpgs from plugs are these
http://www.pulstarplug.com
and
http://www.directhits.com
They are both made by the same company and use the same principles. And no, they cannot be used in conjunction with each other(you will have that question after you read about each of them). They actually don't cost much more than normal plugs, so i consider it a good investment

i fully support making a ls430 faster...or anything faster for that matter 
I figure "spend the least amount of time in the other lane passing as possible"...so when I pull out to pass...i wanna MOOOOVE and when I need to merge onto an interstate I wanna be up to speed as soon as possible
I had the TRD Supercharger on my 96 4Runner and loved it...along with a single turbo in my Supra (11's in the 1/4 ~125mph, only 20-22psi, 504 rwhp) so i'm no stranger to fast
I cant justify $12k for the Tom's SC, but you bet your azz if it was around $5k like most SC kits, I'd have one on my LS430 right now.
The only thing else I'd ever want from Lexus is full time all-wheel-drive with the bigger engines...they offer AWD with the smaller engine IS/GS, but not with the bigger ones...I know they can do it My newer 4Runner is full time awd and has the 4.7L V8...c'mon lexus...stick that awd in a gs430 or IS-F...there is nothing like having all your power to the pavement, with no wheel spin and the same acceleration in dry and wet weather...awesome

No , i don't have them in my car. I am planning on getting them when i need to replace the plugs in like 5k miles. I put them on my friends 2006 GTO and another friends 2005 VW GLI. We didn't dyno test them or anything but they said they could feel a slight difference. I'm not sure about their MPG claims, as they haven't tripped a tank of gas yet to compare. But take everything on a retail website with a grain of salt.
Another thing i forgot to mention is this item i have seen called a "turbonator" http://www.turbonator.com
It simulates the effects of a turbo by swirling the air after the filter. This would benefit the LS a lot more because of the dual air intakes. According to their claims, this would add like 40 hp and around 20-30% mpg increase for $80.
Note: I have not seen these in real life. I have not done sufficient research on these to recommend/explain how they work well. I DO think they add Hp and MPG but as to how much is anyone's guess until some third party results come up. Get them if you want, try them out, if they don't do anything, use that 120 day money back guarantee they advertise

The turbonator has been shown to be an intake restriction. Swirling air down an intake isnt going to do anything but swirl air down an intake. They are lumped in with the electric superchargers.
I've seen nothing on that at all; and I have a huge doubt that Nissan could cram that kind of setup into a car in the same price range as the other two. In fact it sounds like a load of crap. Sources?

There are more, but not enough information. Actually, there was a discussion about the new Q on this site, look it up
I wasn't saying that the Turbonators worked at all. i would actually never put them on my car, they seem like a waste of money. I was just saying that there is an option for him to try

[/rant] and sorry if I sound harsh, but I just hate seeing message forums that have the intent of providing useful, accurate information spammed by people lacking the basic knowledge to filter out the snakeoil bull$#it marketing for some of these products.

for like the third time, the turbonators don't seem like a good idea, i was just throwing it out there...
And what about the pulse plugs, those actually seem legitimate because I've red reviews on 3rd party websites which state they actually work

Im glad I finally stumbled on this thread.
And glad someone else feels the same way.
I dont know how some people can think that doing forced induction on a car makes it ricey in any way. Have you guys seen turbo B-M-trouble-U's or even high end ones for that matter. No reason not to have some extra kick in the pants while rollin in luxury.

You'll have some dealers that will argue no matter what you do, but thats why sema fights for our rights to modify our cars.

I think that LS430 is not underpowered in any way. It is way too fast for its suspension setup anyway. It is NO FUN having a fast car with such soft suspension. And i had a few 13 second cars when i was younger.
So if adding more power is what you are up for, dont forget too make the suspension stiffer to enjoy the car. trust me i had a Lincoln with over 300 HP, was a fun car up unitl about 70 mph.
I would say the cheapest and easiest way to encrease power would be to delete or replace cats with aftermarket units, install an x-pipe and run true dual exhaust. with high flow mufflers. Dynomax has a muffler that is a very high flow unit but is very quiet, its called Hemi Turbo. Or you can go with all the other loud fart cans if you dont mind the noise.
Also I would say that the Lexus motor is very well balanced and makes good power for such a small V8. MB 4.3 liter V8 made 275hp, and BMW 4.4 made 282 HP. None of them as reliable as the Lexus motor.
A mild. reliable twin turbo setup would rock a-- though, I must say.

Thats all were after, or a nice quiet supercharger setup like the TOM's

Well put. But i would not touch an LS 430, GS maybe, but LS not.
Also I would play with an S55 MB if i had one, it already has a 500 HP motor with a blower so its easier to play with since it was born to run.
