These Upgrades Completely Changed My S15 - SR20DET Build

In this episode of the 1999 Nissan Silvia S15 build, I tackle some essential maintenance and upgrades to keep the engine running cool and reliable. I install Yashio Factory lightweight pulleys, replace the OEM Nissan SR20DET thermostat, and swap out all the accessory belts using HKS Fine Tune V-Belts. I also walk through how to properly tension SR20DET belts, a step that’s often overlooked but critical for performance and longevity. To finish things off, I install pinch weld adapters, making future maintenance easier and safer. If you’re working on an SR20DET, building an S15 Silvia, or maintaining a JDM Nissan, this episode has practical tips that might help out.
