A properly implemented nitrous system will not ruin the life of a car - especially when I switch cars every 2-3 years; we're talking proper plugs, jets, activation switches/thresholds, etc. I wouldn't entertain the kit that was suggested by Holly without several key 'optional' components.
Yes, I intend on supercharging and yes, I spend stoopid amounts of money on cars and motorcycles but hey, if you're not going to push the limits of your car don't knock the others that do.

Amen brother!!!!!!!
I will end supercharging my IS350 too....
The reason why I started this thread was to see if any one started researching it.
Because of the compression on the car supercharging will be a problem also....
So researching now for nitrous will help out for supercharging later....
Please no more "why would you want to put nitrous on a luxury sedan for" posts.
I'm getting a little tired of reading those posts...
It is a really nice sedan, but quit acting like the car cost hundreds of thousands of dollars.....
Just my rant...
Also does anybody have more information on the fuel-injection system for the IS350?
I would like to find out a little more about it to see if this car really does run that lean..

My last car was sprayed. I designed the kit from the ground up. It was installed on a 1999 Mitsubishi Galant. See it by clicking here. Secondary Link
It IS possible to build a kit safely. Mine had RPM window and TPS based activation. It was a lot of fun because it really would blow the doors off of many cars. (Mostly because it would pull hard off of the line - Muscle cars don't have the low end power, their power typically lies in the top RPM ranges). I probably ran more than 8 orr 9, 10lb bottles through that engine, with NO problems at all..
Anyways, first, since our engines are approximately 12:1, it makes me nervous to juice the IS. As many people have pointed out, it would be a waste to blow the engine and find out the hard way.
Here in California, Nitrous isn't legal for street, atleast not any of the applications that would be appropriate for our cars. (I believe that NOS brand Nitrous kits are CARB certified on some of the american cars models).
Personally, I'd wait for a CARB legal Supercharger from TRD.

That would be nice if TRD came out with one....
ANy ideas on how to lower the compression?

I'm not as concerned with the ability to install the system, or even getting the correct tune. (Can be done on a dyno with a wideband O2 sensor).
I'm more concerned with the interactions with all the technology in the engine and engine control electronics. The variable timing could end up bending a valve during detonation. Detonation may occur if the ECU has the timing advanced too far.
Traditionally, when one floors (wide open throttle) a modern can, the ECU goes into a mode where it ignores it's fuel maps and uses a baseline map for power. One would assume that since this has been the way it has been done for years, the IS would be no different. However, it would be a very expensive mistake if the ECU tried to adjust the engine's timing or fuel in response to the O2 sensors reading too lean or too rich under nitrous spray.
