TUNING THE NISSAN CA18DET (S13)
Another Nissan CA18DET S13 session at FC Tuning. The CA18DET in the S13 180SX is a classic turbocharged engine from Nissan’s early 1990s performance lineup. Despite its smaller displacement versus the later SR20DET, the CA18 remains popular for lightweight builds and track use.
FC Tuning carried out a full ECU remap on this S13 using our Nistune ECU solution. Fuel maps, ignition timing, and boost control were all carefully optimised on the rolling road to extract the maximum safe power from this CA18DET build.
The car left with improved power output and crisp throttle response — proof that professional mapping makes a significant difference even on a smaller-displacement turbo engine.
