PRODUCT OVERVIEW

Transform your Nissan RB-powered project with the XS-POWER RB20DET / RB25DET T70 Extreme Top Mount Turbo Kit. This comprehensive forced-induction package combines a large-frame T70 turbocharger, top-mount 321 stainless steel turbo manifold, front-mount intercooler, intercooler piping, external wastegate, blow-off valve, V-band downpipe and the essential turbo oil lines and fittings needed for a serious RB20 or RB25 performance build.

Designed around popular Nissan S13 and S14 240SX RB20DET / RB25DET engine-swap applications, this kit provides the major components required to build a powerful top-mount turbo system without sourcing every major component separately.

At the center of the system is the XS-POWER T70 oil-cooled turbocharger featuring a T3 turbine inlet, 0.82 A/R turbine housing and V-band exhaust outlet. The turbo is designed for high-performance applications with a stated 500–600+ HP performance capability when used with the proper engine combination, fuel system, ECU calibration and supporting modifications.
