on a jdm (rhd) supra the ceramic turbos wont last very long even at 400 hp ~17psi. jdm supras also have much smaller injectors, different ecu, cams with less lift & less duration and smaller headers, smaller AR, smaller downpipe and cats, the stock jdm fuel pump is not enough for even bpu... usdm and euro supras generally got bigger and better everything. a "bpu" jdm spec supra is not the same kind of a beast as a usdm or euro spec with the similar mods.
