Hey man im in the same position. I have a 92 sc400 and want to go FI but it just to expensive right now . I saw that there was a supercharger kit in development from Rushimports i thought that it fits the sc400 US model well so far i have my performance TC,mufflers,intake,tranny coller, LS big brake upgrade,and otto strut bar im thinking of ordering the cams and retainer springs and hopefully there will be a SC kit for our cars im hoping to get around 600-650hp out of the V8. well we will just have to wait and see good luck thought.
