Privacy Policy Disclaimer

For the user who wants to enjoy the extra power of a larger turbo to casually attack the circuit and drift, without losing drivability.
Increase Response
Ball Bearing type turbo used to maintain response at lower speeds.
High Power
Compressor wheel is the same size at GT28 series turbos and the exhaust wheel is equivalent of a GT2540. This has enabled high power without sacrificing response.
Wide Range of Use
Ideal for use with a wide range of tuning from stock engines to those which have had upgraded internals and cams.

RB20·25 Sports Turbo Kit
 
  • ER34·ECR33·HCR32(Skyline)/WGNC34(Stagea) GT-RS Sports Turbo kits have now be released extracting further power from the RB20/25DET engines. With low speed response and high speed power, the GT-RS is ideal for a wide range of uses on these engines.

  • New design compressor housing with ported shroud maximises compressor efficiency whilst preventing compressor surge.

  • Stock water lines, which are made of rubber hose, are replaced with flexible tubing with banjo connections to increase heat resistance properties.
