Alfa Romeo 105 with a 2.1 L Twin Spark

Alfaholics transformed this Alfa Romeo 105 series coupe into a “GTA-R 300” at their company in Clevedon, North Somerset, UK.

Under the car’s carbon fiber hood sits a naturally aspirated 2.1 L Twin Spark inline-four. The motor features an aluminum block with custom 94 mm stroke crank, forged steel I-beam rods, and forged pistons. On top sits a ported head with Alfaholics designed camshafts. The motor produces 240 hp at 7,000 rpm on a Motec M1 ECU.

The Twin Spark inline-four is paired to a close-ratio five-speed manual transmission. From there power is transmitted by a lightweight driveshaft to an Alfa Romeo live axle with a limited-slip differential.

Alfaholics improved the car’s handling using to their custom lightweight suspension. It features billet titanium lower control arms, tubular titanium upper control arms, billet titanium uprights, titanium wheel hubs, and titanium rear trailing arms.

A set of Alfaholics designed 15×7-inch wheels cover billet aluminum six-piston calipers with 300 mm carbon ceramic rotors. The rear brakes use two-piston calipers with 280 mm carbon ceramic rotors.

The interior features custom black leather upholstery and Alcantara dashboard. Attached at the end of the steering column is a leather-wrapped Momo Prototipo steering wheel.
