Mohammad Al-Lawati’s 2023 Nissan GT-R Nismo: A 2,200 HP Street Build

1,972.8 WHP with Only 7,000 km!

Mohammad Al-Lawati’s 2023 Nissan GT-R Nismo is a complete 2,200 hp street-performance build developed by Subzero Motorsport in Dubai, UAE.

Powered by a fully built VR38DETT engine, twin Precision Next Gen 6875 turbochargers, a reinforced GR6 transmission and a high-flow flex-fuel system, the vehicle produced 1,972.8 WHP and 1,388.6 lb-ft of torque on the Subzero Motorsport Mainline hub dyno.

The measured wheel-horsepower figure represents an estimated output of approximately 2,200 hp at the engine.

Despite its extreme performance, the GT-R continues to operate through the factory Nissan ECU and retains the functions expected from a premium street car, including air conditioning, cruise control, factory electronics and progressive flex-fuel power control.

The completed vehicle can operate at approximately 1,100 hp at the engine on 98 RON petrol and reach approximately 2,200 hp at the engine on E85 ethanol.

Every stage of the build, from machining and engine assembly to calibration and dyno validation, was completed in-house at Subzero Motorsport in Dubai.

The Story Behind the Build

This 2023 Nissan GT-R Nismo belongs to Mohammad Al-Lawati, a university student in the United Kingdom whose dream car had always been the Nissan GT-R R35.

The vehicle was gifted to him by his father, Mr. Mohsin, giving the project personal significance from the beginning.

Although the Nismo represents the highest factory specification of the Nissan GT-R, the goal was to create something considerably more exclusive: a 2,200 hp GT-R capable of delivering extreme acceleration without losing the identity, functionality or refinement of the original vehicle.

The objective was not simply to produce a high dyno figure. The completed car had to remain street-drivable, serviceable and capable of operating safely on more than one fuel type.

Project Objectives

The build was developed around several clear requirements:

  • Produce approximately 2,200 hp at the engine on ethanol

  • Operate safely on locally available 98 RON petrol

  • Retain the factory Nissan ECU

  • Maintain air conditioning and cruise control

  • Preserve the factory electronics

  • Provide progressive flex-fuel power control

  • Retain controlled street-driving characteristics

  • Avoid permanent chassis modifications

  • Avoid cutting the factory Nismo front bumper

  • Maintain clean and serviceable component installation

  • Integrate additional engine-monitoring and protection strategies

The result is a Nissan GT-R capable of hypercar-level acceleration while continuing to provide the functionality expected from a modern street vehicle.

Main Project Challenges

Building a Nissan GT-R at this power level was not new for Subzero Motorsport. This project represented the company’s 15th GT-R build exceeding 2,000 hp within approximately 18 months.

Many of these 2,000+ hp Nissan GT-R projects have been documented through the official Subzero Motorsport Instagram account.

The primary challenge was completing the entire project within the agreed 8–10 week timeline despite international supply-chain delays.

Another major challenge involved fitting the Bullet Performance beadlock wheel package while retaining the large factory Nismo braking system.

The car uses 18 × 10-inch front and 18 × 12-inch rear Bullet Performance beadlock wheels. Custom wheel machining and additional fitment work were required to achieve the necessary brake clearance while maintaining correct wheel positioning and structural integrity.

The turbo system, fuel system, engine-bay components and crankcase-ventilation system also had to be packaged without cutting the chassis or permanently modifying the factory Nismo front bumper.

VR38DETT Engine Build

The original VR38DETT engine was comprehensively upgraded to withstand the cylinder pressure, torque and sustained operating loads associated with a 2,200 hp Nissan GT-R.

The engine package combines forged and billet internal components with extensive in-house cylinder-head and engine-block machining.

Engine Components

CNC Machining and Engine Preparation

The VR38 engine block and cylinder heads underwent extensive machining and preparation at the Subzero Motorsport machine shop.

These processes were performed to achieve the required airflow, bearing alignment, sealing, component clearances and structural support for high-boost operation.

Cylinder-Head Machining stage 3

  • 5-Axis CNC Intake and Exhaust Porting

  • CNC Combustion-Chamber Machining

  • CNC Fire O-Ring Groove Machining

  • Bronze Intake and Exhaust Valve-Guide Installation

  • Intake and Exhaust Valve-Guide Honing

  • Intake and Exhaust Valve-Seat Installation

  • Intake and Exhaust Valve-Seat Cutting

  • Intake and Exhaust Valve-Shim Clearance Setting

  • Cylinder-Head Decking and CNC Facing


Engine-Block Machining

  • Main-Bearing Line Boring

  • Engine-Block Decking and CNC Facing

  • Water-Jacket Reinforcement

  • Girdle-Support Machining

  • Main-Stud Thread Machining

  • Rotating-Assembly Dynamic Balancing

The engine block and cylinder heads underwent final inspection and quality-control procedures before assembly.

SZM 2,200 HP Turbo System

The turbo system is based around twin Precision Next Gen 6875 turbochargers installed in the factory turbo location.

Turbo-System Components

Turbochargers: Twin Precision Next Gen 6875
Turbo Location: Factory location
Exhaust Manifolds: SZM Turbo Manifold Kit
Wastegates: TiAL 44 mm
Blow-Off Valves: TiAL Q50
Intercooler: Boost Logic Ultimate Race Intercooler
Intercooler Piping: SZM Intercooler Piping Kit

The Precision Next Gen 6875 turbochargers were selected for their combination of high-rpm airflow capacity and usable mid-range response.

This makes them suitable for a high-power GT-R intended for both street driving and roll-racing applications.

A major advantage of this configuration is its factory-location fitment. The turbochargers were installed without cutting or permanently modifying the vehicle’s chassis, helping preserve the structure and integrity of the original Nismo.

The SZM turbo manifolds, TiAL wastegates and EcuTek boost-control strategy provide controlled boost pressure throughout the operating range.

Charge-Air Cooling System

A Boost Logic Ultimate Race Intercooler was installed to manage charge-air temperatures during high-boost operation.

Its large intercooler core works with the SZM intercooler piping system to improve airflow and maintain more consistent intake-air temperatures during dyno testing, street driving and repeated acceleration runs.

The system is paired with TiAL Q50 blow-off valves to release excess charge pressure during throttle closure.

Boost Logic Dual-Injector Intake System

A Boost Logic Dual Injector Intake Manifold was installed with upgraded intercooler piping and V-band-style clamps.

The intake manifold increases airflow capacity while providing mounting provisions for the secondary Injector Dynamics ID1750x injectors required at higher boost levels and ethanol concentrations.

The primary and secondary injector sets are controlled as part of the vehicle’s complete flex-fuel calibration.

High-Flow Flex-Fuel System

The fuel system was designed to provide the volume and pressure required for approximately 2,200 hp at the engine on ethanol while allowing the vehicle to operate on 98 RON petrol.

Fuel-System Components

  • SZM E5LM Billet Fuel Hanger Kit

  • TI Automotive BKS1001 Brushless Fuel Pumps

  • T1 Motorsports Brushless Fuel-Pump Controller

  • Retained OEM Fuel Lines

  • AN-8 PTFE Fuel-Pressure Regulator Lines

  • SZM High-Flow Fuel Rails

  • Injector Dynamics ID1340x Primary Injectors

  • Injector Dynamics ID1750x Secondary Injectors

  • Aeromotive Fuel-Pressure Regulator

  • Nuke Performance Flex-Fuel Adapter

  • Ethanol-Content Sensor

The dual-injector arrangement provides the fuel capacity required during high-boost operation, while the brushless fuel-pump system maintains consistent fuel delivery under load.

The SZM E5LM billet fuel hanger retains the operation of the factory saddle-tank and venturi arrangement while supporting the upgraded brushless fuel-pump configuration.

Automatic Flex-Fuel Operation

The ethanol-content sensor continuously measures the fuel mixture and sends this information to the engine-management system.

The calibration then adjusts:

  • Fuel delivery

  • Ignition timing

  • Boost pressure

  • Torque targets

  • Available power

  • Engine-protection thresholds

This allows the GT-R to operate on 98 RON petrol, ethanol or a mixture of both without requiring the driver to manually change ECU calibrations.

Maximum power becomes available when the detected ethanol concentration reaches approximately 80% or higher.

At lower ethanol concentrations, the calibration progressively reduces boost pressure, ignition targets and available power to maintain an appropriate operating window for the detected fuel mixture.

Factory ECU and EcuTek Calibration

The GT-R retains its factory Nissan ECU, calibrated through EcuTek by Subzero Motorsport owner and tuner Mohammad Al Jabri.

Retaining the factory ECU allows the car to support the upgraded engine, turbochargers, fuel system and monitoring sensors while preserving the vehicle’s original electronic systems and street functions.

The calibration controls:

  • Primary and secondary fuel injection

  • Ignition timing

  • Electronic boost control

  • Flex-fuel operation

  • Torque management

  • Throttle control

  • Fuel-pressure compensation

  • Ethanol-based power control

  • Engine-protection strategies

Four Independent 5-Bar MAP Sensors

The vehicle uses four separate 5-bar MAP sensors:

  • 5-bar MAP sensor on the left intercooler charge pipe

  • 5-bar MAP sensor on the right intercooler charge pipe

  • 5-bar MAP sensor on the intake manifold connected to the factory ECU

  • 5-bar MAP sensor on the intake manifold connected to the T1 fuel-system controller

Using four independent sensors allows boost pressure to be monitored at multiple points throughout the charge-air and intake systems.

The left and right intercooler-pipe sensors help identify a boost-pressure or airflow imbalance between the two turbocharger systems.

The intake-manifold ECU sensor provides the primary manifold-pressure data required for engine calibration and boost control.

The separate intake-manifold sensor connected to the T1 controller allows the fuel-pump control system to respond independently to engine load and boost pressure.

Additional Engine-Monitoring Sensors

In addition to the four 5-bar MAP sensors, the following sensors were installed:

  • Fuel-pressure sensor

  • Coolant-pressure sensor

  • Ethanol-content sensor

Together, these sensors provide the ECU and fuel-system controller with the information needed to monitor engine load, boost pressure, fuel delivery, ethanol content and cooling-system pressure.

Boost-Control Strategy

The minimum boost pressure is approximately 2.0 bar at zero commanded wastegate duty cycle, relying primarily on wastegate spring pressure.

As the detected ethanol content increases, the ECU progressively increases the permitted boost target, ignition target and available engine output.

This strategy prevents the highest boost and power levels from becoming available unless the fuel contains sufficient ethanol.

ECU Safety and Engine-Protection Strategies

The EcuTek calibration includes several protection strategies designed to reduce power or activate a fail-safe mode when an unsafe condition is detected.

Ethanol-Based Power Control

Maximum boost and ignition targets are enabled only when the ethanol concentration is sufficient.

When ethanol content decreases, the ECU automatically lowers boost pressure and available power.

Fuel-Pressure Monitoring

Fuel pressure is monitored continuously against the required target.

If fuel pressure falls outside the permitted range, the ECU can reduce boost and torque or activate limp mode to protect the engine.

Coolant-Pressure Monitoring

The coolant-pressure sensor helps identify abnormal cooling-system pressure that may be associated with combustion leakage or cylinder-head lift.

Detecting an abnormal pressure increase allows the ECU to reduce power before the condition develops into more serious engine damage.

Independent Boost Monitoring

Separate MAP sensors monitor pressure on the left and right sides of the charge-air system.

A significant pressure difference can indicate a boost leak, airflow restriction or turbocharger-performance imbalance.

GR6 Transmission and AWD System

The GR6 dual-clutch transmission and all-wheel-drive system were upgraded to manage the torque generated by the built VR38DETT engine.

The GR6 transmission uses a main clutch assembly to control power delivery through the gearbox, while the ETS system uses a separate clutch pack to control the amount of torque transferred to the front wheels.

Both clutch systems were upgraded to 11-plate configurations.

Transmission and Drivetrain Components

The Dodson ProMax 11-plate main clutch increases the torque capacity of the GR6 transmission’s primary clutch assembly.

The ETS 11-plate AWD clutch upgrade increases the capacity and durability of the separate clutch pack responsible for controlling front-wheel torque transfer.

Together with the Albins geartrain, upgraded shafts, billet transmission components and reinforced differential assemblies, these upgrades allow the complete drivetrain to manage high-power street driving and roll-racing loads while maintaining all-wheel-drive operation.

Turbo Manifolds, Exhaust and Intake System

The SZM Turbo Manifold Kit is paired with:

  • 4-inch downpipes

  • 4-inch Y-pipe with dual TiAL 60 mm external wastegates

  • ARMYTRIX 4-inch exhaust system

  • Full 4-inch titanium intake pipes

The two TiAL 60 mm wastegates incorporated into the exhaust system open above the configured boost pressure threshold to reduce exhaust backpressure during high-boost operation.

The complete intake and exhaust arrangement was developed to provide high airflow capacity, minimal restriction and practical service access.

Crankcase-Ventilation System

A high-capacity catch-can system was installed with a breather tank mounted on the front crash beam and a custom drainage arrangement.

The system manages crankcase pressure and oil vapour during high-boost operation while maintaining an organized engine-bay installation.

The factory Nismo front bumper and bodywork were preserved without cutting or permanent modification.

Bullet Performance Beadlock Wheels

The GT-R is equipped with Bullet Performance beadlock wheels designed for high-power performance applications.

Wheel Specifications

Front: 18 × 10 inches
Rear: 18 × 12 inches
Design: Beadlock

Fitting the 18-inch front wheels over the factory Nismo braking system presented a significant clearance challenge.

Custom wheel machining and fitment adjustments were required to provide adequate clearance around the large factory brake components while maintaining correct wheel positioning.

The 18 × 12-inch rear beadlock wheels provide the width and tyre support required for transferring the vehicle’s extreme power to the road.

Dyno Calibration and Performance Results

Final calibration and validation were completed on the Subzero Motorsport Mainline hub dyno in Dubai.

98 RON Petrol Calibration

On 98 RON petrol and approximately 2.0 bar of boost, the vehicle produced:

880 WHP

This represents an estimated output of approximately 1,100 hp at the engine, depending on the drivetrain-loss calculation used.

The petrol calibration allows the vehicle to operate on commonly available premium fuel with controlled boost and power.

E85 Ethanol Calibration

On E85 ethanol and approximately 3.85 bar of boost, the vehicle produced:

1,972.8 WHP
1,388.6 lb-ft of torque

The measured wheel-horsepower result represents an estimated output of approximately 2,200 hp at the engine.

Final Mainline Hub-Dyno Figure

Peak Power: 1,972.8 WHP
Estimated Engine Output: Approximately 2,200 hp
Peak Torque: 1,388.6 lb-ft
Maximum Boost Pressure: 3.85 bar
Ambient Temperature: Approximately 40°C
Fuel: E85 ethanol
Dyno Type: Mainline hub dyno

The final result was achieved in an ambient workshop temperature of approximately 40°C.

According to Mohammad Al Jabri, the output exceeded expectations for the conditions and demonstrated the combined effectiveness of the engine package, Precision turbochargers, Boost Logic intercooler, high-flow fuel system and EcuTek calibration.

Final Result

The completed 2023 Nissan GT-R Nismo produces approximately 1,100 hp at the engine on 98 RON petrol and an estimated 2,200 hp at the engine on E85 ethanol.

The highest directly measured result was 1,972.8 WHP and 1,388.6 lb-ft of torque on the Subzero Motorsport Mainline hub dyno.

More importantly, the vehicle retains the characteristics required from a genuine high-power street build:

  • Factory Nissan ECU operation

  • Automatic flex-fuel capability

  • Air conditioning

  • Cruise control

  • Factory electronics

  • Controlled street-driving characteristics

  • Progressive power based on ethanol content

  • Integrated fuel-pressure protection

  • Integrated coolant-pressure protection

  • Four independent 5-bar MAP sensors

  • Independent left and right boost-pressure monitoring

  • No chassis cutting for the turbo system

  • No cutting of the factory Nismo front bumper

  • Clean and serviceable component installation

The car can be driven at reduced power on 98 RON petrol and automatically access progressively higher performance as the detected ethanol concentration increases.

This combination of power, functionality and integrated protection makes Mohammad Al-Lawati’s Nismo a complete example of a modern 2,200 hp Nissan GT-R street build.
