The 1998 Nissan Skyline 25GT occupies a unique space in the hierarchy of Japanese performance cars. While the GT-R often steals the headlines, this specific R34 coupe has been elevated far beyond its factory origins. Built by the well-known Jimmy Oakes, this machine has undergone a comprehensive transformation into a high-performance street weapon. It arrived in the United States in 2023 and immediately became a canvas for elite-level tuning. Every aspect of the vehicle, from the frame to the electronics, has been touched by high-end engineering. This Skyline is not just a driver’s car; it is a showcase of modern JDM tuning culture.
The Aesthetic Impact of Active Red and Altia Styling
This 1998 Nissan Skyline 25GT makes an immediate impression with its vibrant Active Red finish. During the extensive build process, the car was fitted with a rare Altia body kit. This kit includes a revised front bumper, rear bumper, and matching side skirts for a more aggressive profile. A GT-R-style carbon fiber rear wing with matching risers sits prominently on the trunk lid. To ensure the foundation was solid, the builder replaced various sheet metal components and repaired common strut tower rust. The result is a clean, cohesive look that honors the R34 silhouette while adding custom flair. It successfully bridges the gap between factory elegance and track-ready aggression.
Right-Hand Drive Cabin and Chassis Refinement
The right-hand-drive interior maintains its authentic 1990s feel with bolstered bucket seats in two-tone gray cloth. Interior upgrades are subtle but functional, including a Pioneer CD stereo and a Link Fury X ECU display. Power windows and automatic climate control ensure that the cabin remains a comfortable place for urban driving. Underneath, the car features a heavily revised chassis anchored by BC Racing coilovers at all four corners. It rolls on 18-inch Volk Racing TE37 wheels, arguably the most iconic wheel choice for any Japanese sports car. Stopping power is provided by Z32-specification brakes with four-piston calipers up front. These upgrades provide the handling and braking performance necessary to manage the increased engine output.
Custom 3.1L RB Engine Specs and Performance
The mechanical core of this 1998 Nissan Skyline 25GT is a monster 3.1-liter RB inline-six engine. This custom unit utilizes a bored RB30 bottom end paired with a high-flowing RB26 cylinder head. A Garrett turbocharger provides the boost, supported by a Fenix intercooler and an Artec exhaust manifold. Fuel delivery is handled by DeatschWerks injectors and a Radium fuel rail, all managed by a Link Fury X ECU. This setup produces a visceral soundtrack through a custom three-inch exhaust system and a Turbosmart wastegate. Power reaches the rear wheels through a “big box” five-speed manual transmission and an Exedy twin-disc clutch. An aluminum driveshaft and S14-specification axles ensure the drivetrain can handle the massive torque. This combination creates a linear and explosive power delivery that modern sports cars rarely replicate.
1998 Nissan Skyline 25GT Summary
This modified R34 stands as one of the most thoroughly documented and creatively built 25GT models available. It arrives with a clean Montana title and a Carfax report that is free of accidents. While the odometer shows 148k kilometers, the mechanical heart of the car is essentially fresh from its build. It is important to note that the vehicle has not undergone California emissions testing or CARB inspection. However, for the collector in an unrestricted region, it offers a turnkey experience of JDM perfection. Jimmy Oakes has created a machine that respects the history of the 1998 Nissan Skyline 25GT while pushing its limits. It is ready for its next owner to experience the thrill of a 3.1-liter RB turbo.
