To be honest, I don't believe it is.
The TOMs ecu, at risk of oversimplification, speaks japanese. All the other bunch of ECUs in your car do not. TOMs has many many years of experience programming toyota/lexus ECUs and yet even they tell you they can't do anything for you if you don't have a JDM car.

This regardless of the fact that by the time you're replacing internals like that it would end up being cheaper to just buy the faster version of the IS (350 in case of a 250 owner, F in the case of a 350 owner)
(and all of the above assumes that lowering the compression doesn't then just run you into another barrier like running out of fuel, ECU limitations, the thin cylinder walls, etc)

you should watch the is-f build from elite. Correct me if I'm wrong but the is-f engine has the same bore and stroke of the is350, so the exact pistons they have developed for the is-f should work well in the is350.
The jury is still out on how it will work though. In the pictures it seems as though they tried to keep the dish shape some, so who knows.

I don't know, just saying they could say it's very special when it's just a bit different and no one wants to duplicate it because it's pointless (for other engines) and no one knows what it looks like so no one knows if it's possible to just run a different type of piston etc, etc.
Tons of car manufactures will always claim they have the next best tech when sometimes it's nothing special.
In any case, I'll go down the road of turboing my car when time/money permits.
