IFX-660 PLUS Performance Turbo | Hyundai i30N

Custom Engineered. Value Driven. The Ultimate "Goldilocks" Upgrade.

The IFX-660 PLUS is the latest evolution in our turbo range, designed in partnership with Hi-Spool Industries. While the IFX-700 remains our flagship "off-the-shelf" Garrett kit, the IFX-660 PLUS was engineered in-house to bridge the gap between street drivability and track-ready top-end power—all at a more accessible price point.

Custom Engineered "Goldilocks" Turbine

We didn't just pick a turbo off a shelf; we built one. The heart of the IFX-660 PLUS features a custom-spec turbine wheel designed to sit perfectly between the Garrett G25 and G30 sizes.

• The Problem: Small wheels (G25) offer great response but can choke at high RPM. Large wheels (G30) offer huge top-end power but often suffer from lag and poor street drivability.

• The Solution: Our custom 55mm/51mm turbine provides the "Goldilocks" zone—maximum flow for high-end tuning without sacrificing the snap and response you need for DCT transmissions and daily driving.

The Compressor: Proven G-Series Aero

While the turbine dictates the response, the compressor wheel is the source of the power. We have retained the Garrett G25-660 compressor profile (54mm inducer) because its aerodynamics are world-class.

• Point-Milled Efficiency: Unlike cheaper cast wheels, this forged, point-milled wheel profile ensures higher efficiency at high pressure ratios. This means more boost with less heat soak.

• Instant Boost: The lightweight wheel has low inertia, so it starts making boost the moment you touch the throttle, ensuring the i30N keeps its punchy character.

• VSR Balanced: Every IFX-660 PLUS core is VSR balanced to motorsport standards by Hi-Spool Industries, ensuring vibration-free operation at speeds exceeding 150,000 RPM.

The "Essentials-First" Approach

To provide the best possible value, we have focused this kit on the core performance components—the parts you can't buy at a parts store. By utilizing your existing factory E-Wastegate motor and reusable hardware, we are able to offer the same elite IFX fabrication at a significantly lower entry price. This makes the IFX-660 PLUS the ideal choice for owners who want a high-performance upgrade without paying for redundant parts they already own.

The IFX Shipping Standard

We don't trust cardboard with your investment. Every IFX-660 PLUS is shipped in a custom-engineered, branded wooden crate. Bolted to a structural base and secured with heavy-duty internal strapping, your turbo is guaranteed to arrive in showroom condition. Plus, it makes the Core Exchange process a breeze—just swap the turbos and use the same crate to ship your stock unit back to us safely.

If you’re looking for a high-performance turbo that punches well above its price tag, the IFX-660 PLUS is the perfect choice for your N.
