About Smith and Jones Engineering

Smith and Jones Engineering specialise in the manufacture of lightweight Cosworth YB Race Engines and associated components.

Manufactured in-house are our YB Aluminium Cylinder Blocks and YBM Cylinder Heads.

The cylinder blocks and cylinder heads are manufactured from our proprietary Motorsport castings.

We work closely with the Grainger & Worrall Foundry and Grainger & Worrall Machining, who always ensure the supply of first class Super-Cube machined aluminium castings.

If it‘s a YB competition engine you require, the supply of YB engine parts, or even just some advice, then contact us at Smith and Jones Engineering - we will be happy to help you out.
