What supporting modifications are typically needed with this turbo kit?

To safely and effectively utilize the HKS GTIII-RS turbo kit, you'll generally need upgraded fuel injectors, a higher-flow fuel pump, and an engine management system (ECU) that can be tuned. An upgraded exhaust system and intake are also highly recommended.

What is the benefit of a ball-bearing center housing?

Ball-bearing center housings reduce friction within the turbocharger compared to traditional journal bearings. This results in a faster spool-up time, meaning the turbo starts generating boost at lower engine RPMs, improving throttle response.

Can this turbo kit be shipped to California?

No, this HKS GTIII-RS turbo kit is not CARB approved and cannot be legally shipped to California due to emissions regulations.

Product Details

This is the HKS GTIII-RS STK Turbo Kit, specifically designed for the Nissan SR20DET engine found in S15 and S14 chassis. If you're looking to significantly upgrade the performance of your SR20DET, this turbo kit is a well-regarded option from a respected name in the performance tuning world. It's built to replace your factory turbocharger with a more capable unit, allowing your engine to breathe more freely and produce more power.

The GTIII-RS features a ball-bearing center housing for improved spool response compared to older journal bearing designs. The turbine housing has an A/R ratio of 0.6, which is a good balance for street performance, offering a quicker response than larger A/R housings while still supporting significant top-end power. This kit is designed to be a direct replacement for the stock turbo, simplifying the installation process, though it's important to note that supporting modifications like fuel system upgrades and engine management tuning will be necessary to take full advantage of its capabilities and ensure engine safety. HKS is known for its robust construction, and this turbo is built to withstand the demands of performance driving.

When installing a turbo kit of this caliber, it's crucial to ensure all supporting systems are up to the task. This includes proper exhaust manifold and downpipe connections, oil and coolant lines, and an ECU tune to match the increased airflow. Because this kit is not CARB approved, it cannot be legally shipped to California. Always consult with a professional tuner to dial in your engine's performance safely after installation.
