Most likely retuning of the engine...a little more hp, but less torque.

I don't expect an all-new engine until after 2004.

I heard Lexus has plans for something in the S4 or M style. I don't know if it will be the L-Tuned super charged or the 2JZ-GTE turbo engine.

Do any of you really know anything about this?

All I know is that TRD has been working on a supercharger kit and having some trouble getting it to be reliable (but they are in the early stages of development).

I have no idea if Lexus will up the HP on their own.

The aftermarket should be "ripe" with all sorts of mods though.

i guess is up from 215 hp to 225 hp 2003.5 (same as the last gen SC300)
...may be lexus comes with ways to solving fitting a better exhaust system in a small engine space.. but still a may be ..cos the esmission regulation stricter every model year .. may be Lexus will change the engineat the same time when the Gs series redesign at 2003 ....and will come with a coupe version
because toyota dont want to spend too much energy to redesign a engine just for IS..
