Tuning limitsenthusiast estimates, crank hp on the stated fuel; sources: Project JDM, Toyota Chaser JZX100 guide; method: the analyzer plans on the lower bound of each range
⚑Same story as its 2JZ sibling: the stock turbo is done near 400 hp; a bigger single is the proven path past it (Project JDM).
⚑Thirty-year-old cooling and ignition parts. Refresh both before adding boost to them.
04 The typical path
Stage 1 tune → intake → downpipe → intercooler → Stage 2 tune. Fueling before E85; the clutch on a manual, a gearbox calibration on a automatic before sticky tires.
