With a solid foundation producing around 300 horsepower, many owners seek to enhance their vehicle’s performance. This article explores the top power modifications to elevate your R33 GT-R from 300 to 400 horsepower, focusing on the best intake systems, exhaust upgrades, and ECU tuning options.
Understanding the R33 GT-R
The R33 GT-R, produced from 1995 to 1998, features the RB26DETT engine, a 2.6-liter inline-six twin-turbo powerhouse. This engine is known for its robustness and tuning potential, making it a favorite among car enthusiasts. To achieve significant power increases, modifications must be carefully selected and implemented.
Best Intake Systems
Upgrading the intake system is one of the first steps in increasing horsepower. A high-performance intake allows for better airflow into the engine, enhancing combustion efficiency.
- HKS Super Power Flow Intake: Known for its excellent filtration and airflow, this intake system is a popular choice among R33 GT-R owners.
