TUNING THE NISSAN CA18DET (S13)

The Nissan CA18DET is a 1.8-litre turbocharged inline-four that powered the S13 180SX and Silvia from the late 1980s. While smaller than its SR20DET successor, the CA18DET is a rev-happy and tuneable engine that responds well to remapping and bolt-on upgrades.

FC Tuning mapped this S13 CA18DET using our Nistune ECU solution, carefully optimising fuel delivery, ignition timing, and boost pressure to get the best possible performance from this classic Nissan turbocharged engine.

The CA18DET S13 left the session with noticeably improved power and throttle response — a well-mapped classic that remains exciting to drive.
