Ok.... Do you think it is possible to make an IS go 200 + MHP in the MILE? I have been looking to build a car to do 200 + MPH in the Texas Mile and thought as IS would be ridiculous wicked if it can go 200 MPH. I know there are a lot of super cars that do it but that's no fun. A friend said it would be crazy but possible. This is a hypothetical situation so have fun with it.
WHAT DO YOU THINK IT WOULD TAKE!
How much power would the car have to make?

Aerodynamics and Power are the two keys here. You are going to need at least 650hp and you also are going to have to do significant revisions to the body to add aerodynamics so it has enough downforce at that speed.
I believe stock the IS can do 170 mph and a lil more. The IS does have an 8 speed shifter so you won't run out of gearing
You got money and time, anything is possible!

I was thinking 2JZ swap going for at least 1000 whp. The biggest problem would be putting the power to the ground. I know it can be done with an endless amount of road but it has to be in 1 mile.
hmmm this ones a tough one 
i know of somebody already doing the 2JZ swap into a 2IS and supposedly everything is going smooth and hes a very well known/reputable tuner down here in miami so im dying to see that monster.
but who knows... we can always take a trip to the autobahn
or try out a heavily boosted 2IS

I'm pretty confident that anything under 1000 horsepower would have you failing. Over 1000 horsepower and we're looking at 'maybe' territory. The entire powertrain and driveline will need to be heavily reworked using parts that probably don't even exist (custom fab) or the easier way might be a heavily built 2JZ-GTE. Aerodynamics will need to be tackled including high speed stability but also reduction of drag. This wouldn't just be modding a car... it'd be creating a whole new car with an IS body.
Quite easily??
Even to an IS-F you are talking about needing mods that will cost way more than the IS-F itself and take a team of very skilled mechanics and engineers to pull it off safely and in any way even close to reliably.
The only way you're going to do it 'quite easily' is with a rocket booster strapped on the back.

Maybe one of the math guys can chime in but there is an easy formula to tell you how much power you need to go 200mph once u have a couple figures from the car you are trying to drive.
This should help
http://racingarticles.com/article_racing-21.html
There is an available software application called “Bonneville”?, (a top speed simulation program.) a mathematical formula is used on the computer to simulate a race vehicles top speed using the options that are entered in the formula. Including frontal area, drag coefficient, horsepower, gear ratios, and tire size.
This formula has proven several times what Most Open Road Racers know that as speed doubles, drag coefficient increases by the “SQUARE” (2X2=4). But what most of these enthusiasts don’t know, is that the Horsepower Requirement to double your speed, increases by the “CUBE”.
That means that if it requires100 horsepower to run 100+ mph in a Specific Vehicle”, it will take 800 hp (2X2X2=8) to push the “Same Car” to 200+ mph. Comparing the difference between Drag and the Horsepower requirement it is obvious that it will be easier, (and less expensive) to go faster with a “Swoopier Body” than it

What's the current top speed of the IS-F governed? And what would the top speed be without the speed governor? The difference would be that speed minus 200 mph.
But you are right, in the context of top speed in a distance of over a mile. That's certainly different than just top speed as I was discussing incorrectly.
