Performance vs. stock turbo

The stock B48 turbo has a physical ceiling near 300-330 HP. The R2P IMS-500, thanks to the Garrett G25-550, supports much higher flow without dangerously raising temperatures. This allows for 450 HP with a linear power curve, without the throttle lag typical of poorly sized hybrid turbos. Compatible with original lubrication and cooling lines.

FAQ

• Is ECU tuning required? Yes. To harness the turbo's capability and ensure engine safety, a Stage 3 calibration specific to this kit is recommended.
