There is now official aftermarket support for supercharging of the 3rd Gen GS :

So can comeone translate that website I assume this supercharger is only for the GS430? I like the exhaust they have listed too..

Also, it looks like it's for the G350, not the GS300. Although, I cannot read Japanese characters.

There is a kit for both:

型式：GRS191　　年式：H17年9月～　エンジン形式：2GR-FSE = GS350


型式：UZS190　　年式：H17年9月～　エンジン形式：3UZ-FE = GS430

Correct me if I'm wrong but I'm pretty sure modding the engine will void your drive train related warranty issues. We don't have much history on this car to predict outcomes of modding it. So someone needs to take the plunge. Hopefully it's someone who has paid off their car and/or has lots of money in case they have to fix or replace an engine themselves. Too risky in my book.
Plus, I'm sorry guys but I think this car is too big to be a serious speed demon. Why spend the cash on it. You want a sport car? This isn't it. I love mine because it's a luxury/sport cruizer. When I want sport driving I get in the G-dogg or even the SC. It ain't fast but it handles like a monkey.

It's too early to tell but TOM'S works closely with Toyota to ensure reliability and compatibility of its after-market products.

So many haters, theres a reason why BMW and Mercedes and Audi make big saloons with massive V8s and V10s. There is a market for it. If you've never been in an M5 then you wouldn't understand the marvel of a big saloon that is as fast as a dedicated sports car.

I guess if you don't like the idea of a supercharged GS, then you wouldn't like the following cars either: M5, E55, E63, S55, S65, S6, RS6, and S8 (maybe RS8 if they decide to make it).

I feel like TOM's is the closest thing Toyota has to an AMG (probably more like Brabus). I seriously hope they take off and perhaps one day build engines for Lexus.

I don't think it's hate...it just that those cars you listed are manufactured by the car companies that have divisions that sponsor these cars...I mean they are covered under factory warranty and all that and have been enginered to be really great sport sedans or coupes...I mean lexus doesn't have a division like that and hopefully they do have one...but aftermarket isn't the same as buying the car outright that has the stuff to make it fast and handle well in it already....so I guess it is kind of a waste...I mean most ppl agree that BMW handles much better than a Lexus so if you want performance...get a BMW or whatever car that specialize in that....Lexus doesn't specialize in that market yet so no need to get offended...heh

Very nice upgrades!!!
