Spectrum Motorsports turbocharger offerings for the R32, R33, and R34 Nissan Skyline GT-R are something we've been working on and testing in multiple iterations for the better part of 6 years, and we are pleased to offer this as our quintessential Product line. Dyno results and Customer feedback have been overwhelmingly positive, and this was one niche we knew was worth the continued effort and iteration. Whether it is a responsive OEM fitment bolt-on twin turbo kit, or a motorsports-grade single turbo system, we feel we can provide unmatched performance for your GT-R.

 Ultimate power, delivery, and horsepower output for Motorsport usage.

Beyond the horsepower range of the OEM turbine housings and manifold design, lies the requirement for a tubular manifold.  Utilizing our in-house built stainless manifold, featuring  merge collector(s), external wastegate, and V-band flange or Divided T4 Turbine flange. Your turbocharger of choice can be selected, to match your desired powerband, with our main 58 and 61mm offerings covering a range from 500-750bhp depending on engine specification .  

All of our Exhaust Manifolds are entirely stainless steel (including flanges), are back purged, and TIG welded by hand in our Facility in Vancouver. Our Careful consideration for runner length, collector design, orientation, Wastegate placement, and Turbine flow characteristics ensure optimal performance.

ALL our RB exhaust manifolds are equal length, delivering an enjoyable exhaust sound and even exhaust pulse delivery. Our Single-Scroll V-band Turbine variant utilizes a long-runner design to achieve this, while the Twin-Scroll design features the shortest-possible equal-length runner configuration, keeping Exhaust pulse Energy as high as possible into the divided Turbine Inlet.

Our Twin-scroll RB manifold utilizes a unique arrangement for both merge collectors, allowing for significantly shorter runner length and lower pre-turbine volume than other equal length manifolds. This results in the best match for mid-frame twin-scroll T4 turbines, with fantastic torque and "Area under the curve". 

New for 2022 is the Artec Investment Cast V-band manifold option for Reverse-Rotation Garrett G-series. This compact manifold is cast in 347 stainless, and features smaller 33mm ID runners to improve response and optimized Wastegate flow. 

We have compressor and turbine maps available for all our RB offerings, and can help with advanced compressor and turbine matching to any unique application.
