Our 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 8 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.

All our Spectrum Built Turbochargers have been updated for 2024! The SR/58 has a 1mm larger Compressor Inducer, with updated aerodynamics and reduced blade count to further improve how this Turbocharger performs at low boost pressure. Both SR/59 and SR/61 Turbochargers have been updated for reduced Rotorgroup Intertia and better Response at low-mid boost levels

The SR/65 and new SR/67 Both have a new Turbine wheel, with a much larger 75mm Inducer for better Efficiency and Lower EMAP at high boost Levels. These are Perfect for those on E85 or Race Gas and an engine package ready for 700+WHP.

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, and results in a powerband that comes on hard around 4000 RPM and pulls past 8k with a good cylinder head. Our 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". 

For Anyone using a G-Series Turbochager, we suggest the Artec V-band Exhaust Manifold. This compact manifold is cast in 347 stainless, and features smaller 33mm ID runners to improve response and overall powerband in a single-scroll configuration.

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.
