GT-R Alpha Performance Big Bore Billet Throttle Bodies
At around 800HP, your stock throttle bodies become a restriction to the intake system. By enlarging the diameter of the throttle bodies from the stock 60mm (ID) to a massive 73.5mm (ID), we increased the cross sectional area by 50%. This provides much improved power gains – especially over the 1000HP mark. The highest horsepower producing R35 GTR Throttle Bodies now come in two configurations:Vibrant HD or Standard. We also include extensive installation instructions that make for an easy install.
At around 800HP, your stock throttle bodies become a restriction to the intake system. The negative effects of this bottleneck are exacerbated exponentially as power increases from there on. By enlarging the diameter of the throttle bodies from the stock 60mm (ID) to a massive 73.5mm (ID), we increased the cross sectional area by 50%. This provides much improved power gains – especially over the 1000HP mark.
Since we are a true performance automotive manufacturing company, we employ a team of highly qualified engineers – not some idea based on a whim. Our engineering team was given the task of designing the largest, best-performing throttle bodies on the market to feed our Alpha Performance R35 GT-R Carbon Fiber Intake Manifold and they delivered! Each CNC billet 6061-T6 aluminum housing was specifically designed to provide enough air flow to support up to 2000+HP without issue – implementing enlarged diameter 73.5mm ID bores along with low profile throttle body shafts to minimize restrictions even further.
Alpha Big Bore Throttle Bodies use your existing Nissan OEM drive-by-wire electronics. Simply swap out the internal components from your stock throttle bodies and you are ready to go. Learn more by reviewing our comprehensive installation instructions.
