Swapping and Building with a 13B Engine

Swapping a 13B engine into a project car is a bold statement—one that says you want something unique, balanced, and potent. Unlike conventional piston engines, the 13B’s compact design and low weight make it ideal for ambitious builds that demand high performance without catastrophic packaging disruptions. At All American Motors Hub, we specialize in supporting these swaps and builds with the parts, guidance, and expertise you need to succeed.

One of the major advantages of the 13B engine swap is that it allows you to exploit power-per-weight efficiency. Because it’s compact in length and width, retrofitting a 13B into many chassis becomes easier than you might expect. Often, it slips into tight engine bays where a V6 or inline-4 might struggle. The simplicity of the rotary design—fewer reciprocating parts, no camshafts, valves, or timing chains—also means fewer failure points and potential packaging headaches.
