Performance & Application

Designed around the GEN2 billet compressor wheel, this GTX3576R configuration is purpose-built for high-output SR20DET applications running a top-mount turbo layout. The dual ball bearing center cartridge delivers sharp throttle response and reduced turbo lag compared to journal bearing designs, while the .63 A/R T3 turbine housing balances quick spool with the flow capacity needed to reach serious power levels. The 3″ GT VBAND conical exit with 81mm lip simplifies downpipe fabrication and improves exhaust flow efficiency. This setup is ideal for SR20DET builds targeting maximum power without sacrificing daily drivability or response.

Compatibility & Fitment

• Nissan SR20DET
• Nissan SR20DET GTX T3 Top Mount applications
