Nissan 370Z / G37 build guide
VQ37VHR · 3.7 NA V6. What the stock hardware reliably supports, where it breaks first, and the fastest safe path to more.
The Nissan 370Z / G37 makes 332 hp stock at roughly 3,300 lb (9.9 lb/hp). Its stock internals are good for about 520 hp, the fuel system for around 390 hp, and its naturally aspirated setup tops out around 380 hp without forced induction. Below is the limit sheet carbuildcheck analyzes against, plus the platform's documented weak points.

03 Where it breaks first
The 370Z’s oil-temp derate on track is famous — an oil cooler is the first mod, before anything that adds power.
The clutch slave cylinder (CSC) is the known weak point — upgrade to an external unit with any clutch job.
04 The typical path
Intake → headers → tune → cams or forced induction. NA gains are honest but small; the big unlock is boost, and boost starts at the fuel system.
