How would you get sub 5 second 0-60?

(Ignoring the obvious and expensive methods of pumping more power to the wheels)
1) Find ways to reduce the weight of the car and/or driver
2) Use shorter gears in the rear end
3) Reduce air intake and exhaust restrictions
The 350 isn't that far away from being a sub 5-second car. If they'd drop in a manual transmission, that alone would probably do the trick.

knocked off the 0-60 time with a manual tranny, (if any)...Just look at the old supra turbo,
it has even more HP and is a bit lighter and in a 6 speed tranny form, it still can't break into the 4 second
range... I think lexus did a great job with this auto tranny (over all)..
Hefty, chunky, zofdig...
I think the biggest problem with the IS is its weight. The car with passenger(s) touches two tons.
Lose the weight by having sports wheels and tires, changing the leather seats to racing seats, gutting the interior of unnecessary weight, plastics, and sound absorbing materials, try to get an IS350 without a moonroof, carbon fiber hood and trunk, and the driver should lose a few pounds.
Then you can start on the engine and exhaust...

because it removes the rear cats and replaces the stock resonators with high flowing ones..
It should give you anywhere from 15-20hp... That along with a Joez intake pipe and an HKS drop in replacement filter which should give you another 3-6hp..Total being an increase of 18-26 hp.. For now, that's about all you can do to the IS350 , that i know of..

This car is not THAT heavy for a four door car, and if it was say 500lbs
lighter, in real world driving, it'd be that much easier to have your back end kick out and
lose control when you hit a bump in taking a hard corner..IE: Corvette..

The whole point of the IS350 is to blend performance and luxury. If an owner is willing to strip out most of the luxury in the quest for more performance, me thinks he bought the wrong car. There are any number of cars, e.g., WRX STI, EVO, that are quick, less expensive, and cheaper to modify.

The heavier cars have to use fatter tires and appropriate suspension tuning to make them handle well in the twisties.
Take a look at the Lotus Elise, Lotus Exige, and Ariel Atom. 3 of the lightest (very light), and best handling production cars on the planet. Lighter is always better (I can't think of any instances where that claim wouldn't hold true).
