 42/R - Power Delivery

The RB26DETT specific 42R turbocharger is the ideal choice for GTR's with typical bolt-on modifications and pump fuel. These responsive 42mm turbochargers fit with OEM manifolds, lines, and charge pipes while still being able to support 550BHP with plenty of torque available. Built around two Ceramic Ball Bearing CHRA's for extreme reliability in race conditions, careful design and sizing of the Compressor allows for extremely good response while avoiding compressor surge.  On the turbine side, our own 9 blade, 68 trim RS turbine wheels provide exceptional response and a broad powerband. Each set comes standard with 12-16PSI adjustable wastegate actuators and hand-ported wastegate port. This specification has been tested and validated with our Friends at U.P. Garage In Washington state, and are available for sale in the USA exclusively through them. Please email fairladymotors@hotmail.com, or message on facebook at www.facebook.com/upgarage.

45/R - Ultimate Street Twin Turbo

The 45/R Twin Turbo Combination is perfectly matched to the powerband of the RB26 with stock or mildly upgraded cylinder head. With twin billet Compressor capable of 37lb/min of airflow each, peak compressor operating efficiency is shifted to 4500-8000 RPM, and  with 84 Trim .48A/R turbine housings to help reduce expansion ratio while maintaining responsive boost characteristics. This turbine match ensures engine delta pressure remains even at high RPM, allowing for over 80% of peak torque from 4500RPM - 8500RPM with 2.6L displacement. These Turbochargers are capable of supporting 600BHP with the right 2.6-2.8L Engine package. Each set comes standard with 16PSI adjustable wastegate actuators and hand-ported wastegate port.

47/R - All-out Power

The 47R compressor supports an impressive 40lb/min of airflow each in an extremely light and compact package. This turbocharger utilizes a 47mm compressor with Two-piece billet Ported Shroud to ensure a broad flow range, capable of supporting significant boost at 4500RPM and up to 30PSI at 8500 RPM.

48/X - Max-Effort Bolt-On

For those looking to find the upper limits of aftermarket Cast Exhaust Manifolds and Turbine Outlets on the RB26, these point-milled, low-Inertia 48mm Compressors offer exceptionally high Efficiency and up to 45lb/min, WITHOUT a reduction in response. Being able to support such mass flow through a relatively small inducer diameter avoids potential Compressor Surge and response issues... common with other "large" RB26 twins

Best suited for 2.8L+ and / or High RPM and Volumetric Efficiency Cylinder Head packages. Each set comes standard with 16PSI adjustable wastegate actuators and hand-ported wastegate port.
