Community-documented crank-hp planning figures, conservative by design. How these are used in the score →
03 Where it breaks first
The stock turbo is maxed here, and the Theta wants oil and knock monitoring as boost climbs.
A budget RWD turbo chassis: bushings, cooling refresh and honest maintenance before power.
04 The typical path
Stage 1 tune → intake → downpipe → intercooler → Stage 2 tune. Fueling before E85, driveline before sticky tires.
