900-HP Monster: Nissan 180SX with Skyline GT-R’s RB26

Epic Results: Nissan’s S-Chassis and Godzilla Unleashed

The SR20 engine from Nissan has become a widely sought-after option for individuals looking to swap out their current engine, particularly among those who own older models of the Nissan Z car. Despite this trend, one owner of a 180SX has decided to go against the norm and replace their stock SR20 motor with an RB26 engine sourced from a Skyline GT-R.

Chris Kostakis, the proud owner of the 180SX project, frequently brings his beloved Nissan two-door to track events. He specifically opted for the impressive RB engine due to its substantial horsepower and consistent performance, a perfect fit for the demands of the track. Nevertheless, in order to accommodate the additional weight of the new engine, he took the necessary steps to enhance the suspension system with top-of-the-line Bilstein coilovers. Additionally, he equipped the 180SX with a set of robust 295 tires for optimal grip on the track.

One Modification TRANSFORMED This Car

This particular RB26 engine used in this project is anything but ordinary, as it has been heavily modified with a Spool Imports RB29 stroker kit and custom cylinder heads from Rams Head Service. Along with these enhancements, the build also boasts a powerful BorgWarner EFR 9280 turbocharger, a top-of-the-line Holinger RD6 sequential gearbox, and an advanced Motec M150 engine management system. To ensure maximum performance and reliability, a dry sump system from Peterson Fluid Systems was also installed.

In order to handle the increased horsepower, the original RB26 engine block has been substituted with a more robust N1 RB26 block, along with CP-Carrillo rods and pistons. This improved setup enables the build to reach a maximum output of 1,500 horsepower. However, for drag racing purposes, Chris reduces the power to a safer 900 hp, and when on the track, it is further lowered to around 550-600 hp.

To assist with optimizing the vehicle’s performance, Ben of Benchmark Solutions intervened by reprogramming the Engine Control Unit (ECU), eliminating some of the midrange torque in order to improve drivability.

Furthermore, the vehicle boasts a top-notch Bosch ABS system that has been thoughtfully altered to allow for a smoother ride compared to its original settings. Additionally, Chris skillfully disables the stability control feature, opting instead to utilize the available resources, such as the enhanced braking system. This consists of AP Racing Pro 5000 Rs in the front and Endless four-piston brakes in the rear. Despite these upgrades, the original brake booster and master cylinder have been maintained to preserve its practicality for everyday street use.

The interior of the Japanese sports vehicle closely resembles its factory design, yet it has been modified for optimal track performance with a roll cage and racing seats.

The Nissan 180SX is far from being finished, as its owner has grand plans to enhance its aerodynamics with additional parts. These modifications are crucial for improving lap times during time attack competitions. This further proves the impressive adaptability of Nissan’s S-chassis model, making it a highly sought-after choice among car enthusiasts. The 180SX boasts great versatility, whether it be for an affordable drift car or a meticulously designed drag/track vehicle. Thanks to the remarkable aftermarket support for this model, the possibilities for customization are endless. You can take your build in any direction you desire.
