Performance versus the original turbo

The B48's stock turbo has a physical ceiling close to 300-330 HP. The R2P IMS-500, thanks to the Garrett G25-550, supports much higher flows without dangerously raising the temperature. This allows 450 HP to be reached with a linear power curve, without the loss of response characteristic of poorly sized hybrid turbos. Compatible with the original lubrication and cooling lines.

Frequently asked questions

• Is it necessary to remap the ECU? Yes. To take advantage of the turbo's capacity and guarantee engine safety, a Stage 3 calibration specific to this kit is recommended.
