Hi, If you still in to the Supercharger for ur RX300, I got one on mine,
I will tell you this its fun how everyone thinks is a slow car, but now I got 500+ WHP and its fun to drive it,
I got the super charger from TRC 2 years ago, its not easy to install since its designed for solora,
I will tell you this its going to cost you alot,
I got the supercharger kit for $4000 since I got a bigger one, had to change my hood since it would not close anymore,
after that need to buy a exhaust system for it prety much a custom made since u will need a 2.5 or 3" $1500 and after all that u have to upgrade your pump,
since RX300 pump is in the tank it takes a few sec before respond and you have to find some aftermarket and build it ur self I used a Mitsubishi GSX pump since I have that car too, I will tell u this u will probably be one of the few ppl having a car like it but I will need a lot of customization and time,
If u think of taking it to a shop to do it, first not that many companys will do it, but even if they do they will charge u over 10K to install something that mill max give u around 100 more HP
