The 1.8L I4 is an engine swap featured in Forza Motorsport (2023).

Synopsis[]

The 1.8L I4 with 245 hp (183 kW) in the Forza series is a small capacity engine that can be swapped onto some compact cars. It originates from the Ford Escort RS1600 Fast & Furious Edition.

Offering 245 hp (183 kW) in stock form and 608 hp (453 kW) maxed out, the 1.8L I4 may be viable for higher class builds, but its low torque value of 388 ft·lb (526 N·m) will limit its top speed.
