03 Where it breaks first
Ceramic exhaust wheels on stock turbos shatter when pushed — swap to steel-wheel units before raising boost hard.
High-rpm oiling is the RB’s weak spot: crank collar, upgraded pump and a baffled pan for sustained big power.
04 The typical path
Stage 1 tune → intake → downpipe → intercooler → Stage 2 tune. Fueling before E85, driveline before sticky tires.
