oh yeah, i forgot to mention that the US spec Supra is waaaaay better than the Jspec supra
The Supra offered in Japan (and other areas where Jspecs are sold) has:
440cc Injectors (US Spec has 550cc i think)
Smaller Ceramic Turbines
Map Sensor instead of MAF
Different EGR gear
ECU
those are the differences... so the Supra here puts down over 45hp more stock
