This mod brings three realism-focused rotary engines to the Ibishu BX, covering the 1.3L 13B two-rotor, 2.0L 20B three-rotor and 2.6L 26B four-rotor units. Each engine starts naturally aspirated from the factory and can be upgraded piece by piece, just like the vanilla BeamNG.drive engines.

Players get a wide range of intake and turbo options, from stock and race intakes to sequential twin turbos and variable boost turbo stages. The rotor housings can be swapped between street, bridge and peripheral port designs, each changing the power delivery and idle characteristics. A detailed damage model simulates rotary-specific failures like apex seals and eccentric shaft bearings, while custom-recorded engine sounds and a new high-revving gauge cluster round out the experience.

With 11 ready-made configurations ranging from a 225 hp street car to pro drift builds and a nearly 1,400 hp four-rotor drag car, this mod suits players who want authentic rotary engine behavior and tuning depth in their Ibishu BX builds.
