aww dang, i got excited for a bit, just read the other thread. I might as well just sell my car and get a IS350

 

that has always been the case for 250 owners (in the US anyway) and suspect it will always remain so.

 

I was reading on it earlier and yes it is cheaper to trade in for a 350 with warranty..

apparently somebody said it's really big in Africa because they don't have the 350 there

 

would this kit fit a 350?

 

Physically? Sure... just like the 350 supercharger kits fit the 250.

In neither case does it add enough power to be worth the sticker price of the kit/install/etc though compared to just getting a faster IS... this is more pronounced in the 250 since the price jump for >100hp to a 350 is smaller than the price jump for >100hp to an IS-F is... but generally speaking supercharging a 2IS seems to run "around" $1000 per hp not counting labor (unless you cobble together a used kit or something) with the top end being +50-70 hp... if you wanna push into that 70 range you're probably looking at needing to make an F-con or MAPECU3 work, which tacks some more costs on though... so 350->IS-F starts looking pretty reasonable in comparison give you add another 30+ hp and get a better transmission (and presumably some warranty)

 

i am new to this but are u saying a charger kit will not be worth the cash outlay as apposed 2 buying a is 350

 

Exactly that.

There's about a $4500 difference brand new between a 250 and 350. A supercharger setup will run you 2x that amount with labor, or more, and give you half the hp gain.
