Wink1100- My car is older one a 1992 SC400 but just about completely restored in and out. It now has 107,000 miles on it. Wow, mods ok just a few to mention:
Dragon Torque Converter
Rear exhaust change out piping and straight thru mufflers
High flow cat
Intake: injen snorkel, custom highflow inlet airflow, Rod Millen air filter, air inserts...
Electrical cables, wires, batt, etc....
ECU piggy back (apexi)
Walbro fuel pump
Electric fan/
Supra LSD torsen
Nos and plugs
Fat rears/Eibachs springs/tomiko shocks
Currently installing S&S headers and EGR block
Y section exhaust upgrade
Supra big brakes/rotors
Leather inside/re-painted same color
instrument cluster, etc...
the list goes on and on, those are the basic's for performance and looks...
I would consider Kelford cams if I can get this tranny upgrade under control...
The most important or most effective upgrades were with the torque converter and exhaust upgrades... Look into the Eaton superchargers, made in Australia but proven to perform well with the sc400 engine.. That would be my first choice in supercharging with the boost you want. I believe that Eaton comes with all the hardware needed to install for the most part. You may need larger fuel injectors, fuel pump, etc.... You can't just slap a supercharger on and say go baby go...A little more to it...not much more...
