PRL Motorsports 4847RS Turbo Upgrade | Honda Civic 1.5T, Acura Integra 1.5T, Honda Accord 1.5T
The PRL Motorsports 4847RS Turbo Upgrade is designed as a direct replacement for the factory turbocharger on Honda and Acura 1.5T platforms. This stock-location turbo upgrade installs without modification, maintaining OEM fitment while increasing airflow and overall performance capability. It is built for drivers looking to move beyond basic bolt-on upgrades without transitioning into a larger, more complex turbo system.
Performance and Turbo Design
This turbocharger focuses on delivering increased power across the rev range while retaining responsive spool characteristics similar to the OEM unit. By increasing both compressor and turbine sizing, the design improves airflow efficiency and helps carry power further into higher RPM where the factory turbocharger typically tapers.
A Si3N4 ceramic ball bearing CHRA is used to reduce friction and support consistent boost response. The combination of a larger wheel design and efficient bearing system results in improved midrange and top-end performance while maintaining predictable drivability for both daily and performance use.
