Overview

The 034Motorsport K26/GT3071 Dual BB Turbocharger is a high-performance turbo designed for significant power output. It features a smaller turbine and compressor wheel compared to the GT30R, making it ideal for fast-reacting, small-displacement engines aiming for up to 500 crank HP. This turbo can achieve full boost by 3000 RPM on most 2.0-2.3L motors and efficiently handle over 40psi of boost.
Show original supplier description
The 034Motorsport K26/GT3071 Dual BB Turbocharger is engineered to be a superior replacement for the RS2, offering faster spool-up and substantially increased power output. Its design incorporates a smaller turbine and compressor wheel, making it an optimal choice for small displacement engines requiring a quick-reacting turbo capable of producing up to 500 crank horsepower. This turbocharger is capable of reaching full boost as early as 3000 RPM on most 2.0-2.3L engines and can efficiently manage boost pressures exceeding 40psi. This turbocharger is available with various turbine housing options, including those compatible with stock K24/26 applications and Garrett T3 and GT housings. Customers can specify their desired turbine housing in the comments field during checkout. Additionally, it is offered with a 3" or 4" inlet, requiring customer specification. The product is also available with different A/R ratios (.63 or .82) and inlet sizes (2.75" or 4" Bell-mouth), which must be selected by the user. Please note that this product is sold for racing use and for use on vehicles not registered for on-highway use. It is not legal for use on emissions-controlled highway or street vehicles. By purchasing, you acknowledge and agree to these terms.
