Michael Scullin’s Ford Sierra is not your average classic Ford. While from a distance it might appear to be just another Sierra with a turbo engine and lowered suspension, a closer inspection reveals a meticulously crafted, one-of-a-kind machine. This isn’t just a car; it’s a testament to passion, ingenuity, and a dedication to pushing automotive boundaries. Let’s delve into what makes this Ford Sierra so special, exploring the modifications that transform it from a humble classic into a true showstopper.

The journey to appreciate this Sierra began at Dubshed, an automotive event where unique builds often steal the spotlight. It was there that Michael’s Sierra first captivated attention, demanding a closer look and a deeper understanding of its creation. Built in a modest home workshop in rural Northern Ireland, this Sierra is a product of passion and skill. Michael, the owner and builder, also hosts the “Limited Slip Differences” podcast, further showcasing his deep-rooted love for cars and automotive culture.

Subtle Exterior, Wild Heart
Starting as a standard Ford Sierra with a 2.0L twin-cam engine, the typical modification path might involve RS Cosworth wheels and a performance-oriented stance. However, Michael envisioned something far more ambitious. The exterior, finished in a striking Fire Red, maintains a degree of subtlety that belies the extensive work beneath the surface.

Interior Refinements and Performance Cues
The interior of this Ford Sierra echoes the exterior’s understated approach, yet features significant upgrades that blend comfort and performance. Mitsubishi Lancer Evolution VII Recaro front seats, re-trimmed in suede, offer enhanced support and a touch of luxury. The rear bench, sourced from a Sierra Sapphire RS Cosworth, maintains the car’s lineage while adding a premium feel.

A chunky three-spoke RS Cosworth steering wheel, coupled with power steering from an Opel Astra, enhances driver control and feedback. A-pillar gauges monitoring air/fuel ratio and boost pressure, along with center console gauges for oil temperature and pressure, provide crucial engine data. The addition of a hydraulic handbrake signals the car’s performance-oriented nature, hinting at its capabilities beyond just cruising.

The Heart of the Beast: Saab Turbo Power
Under the hood is where this Ford Sierra truly diverges from the norm. Instead of the expected Ford Cosworth YB engine, Michael opted for a Saab B204 – a 2.0-liter, 16-valve turbocharged engine from the now-defunct Swedish automaker. This engine has gained popularity in the modification scene as a potent and cost-effective alternative to engines like the Nissan SR20DET or Cosworth YB.

The Saab B204 engine, originally found in Saab 900, 9000, and 9-3 models, is known for its robust construction and tuning potential. Michael, with the expertise of Ali McClelland from Ali’s Garage, has maximized this potential. The engine build includes a Pulsar 5449G (G25-660) turbocharger and a Precision Turbo PW46 external wastegate, significantly enhancing performance and reliability.

Fuel delivery is handled by an uprated pump and 875cc injectors, while a FMIC Performance front-mount intercooler and Honda throttle body optimize intake air. A Lee Smart Racing custom aluminum radiator ensures efficient cooling, crucial for maintaining performance under demanding conditions. The result is an engine setup aiming for an impressive 480hp once ECU mapping is finalized.

Driveline and Suspension: A Fusion of Components
The unexpected engine choice is complemented by an equally unconventional driveline. The Ford Sierra now utilizes a BMW E30 M3 5-speed gearbox, chosen for its strength and gear ratios. A Saab 9-5 Aero flywheel, Sachs pressure plate, and custom six-paddle clutch manage the power transfer. A custom prop shaft connects to a Sierra RS Cosworth rear end equipped with a Gripper Differentials LSD (Limited Slip Differential), ensuring optimal traction and handling.

Perhaps the most visually striking modification is the custom hydraulic suspension. Unlike air suspension or coilovers, this hydraulic setup is designed for stance rather than bouncing. Each corner is individually controlled, powered by a converted B7 VW Passat pump. This system allows for precise height adjustment and, crucially, the narrower hydraulic uprights provided the clearance needed to fit the chosen wheels.

The wheels themselves are timeless white Buddy Club P1s, adding a Japanese influence to this European blend of Ford, Saab, BMW, and Porsche components. Behind these wheels are Porsche 911 brakes, adapted to Ford Granada hubs, providing substantial stopping power.
