i was looking at the engine compartment and there's definately sufficient room for both a large turbo (notice all that space just left of the engine when facing the car)... but a superchargers will have to piggyback the engine and that'll mean the black plastic engine cover will have to go.. and perhaps the insulation on the underside of the hood...
i must admit that the thought of adding any sort of forced induction sounds appealing but... although a supercharger should add at least 75 hp... at a decent level of boost... performance isn't going to improve by as much as some people hope... its not going to become an M3, S4 or C32 fighter... the main problem with adding a supercharger will be the auto tranny... the GS400 is 300hp/310lb/ft stock, so it should handle a supercharger.. but barely... (assuming the IS is the same spec. as the GS4's)...
in my humble opinion a supercharger/turbo on this car is a waste of money... not worth an extra 5-6K to take a second and a half (at most) off the 0-60 times... $500 NOS upgrade will do the same thing (if not more)... better to spend 2-3K on suspension upgrades, a set of slicks and race school/driving lessons...
95% of IS300 drivers (myself included) don't have the skills necessary to take the car to anywhere near the limits of its capabilities (even in stock form)... 0-60 is for punks! anyone can stomp on a throttle and aim straight...
hitting an apex perfectly... now that takes skill...
