We work to provide custom support for the engine part of the racing effort. We specialize in four cylinder high rpm engines and have experience with all types of engines from Inline 6 to V-12.

Vintage engines are a large part of our business; specifically Cosworth four-cylinder engines, Brian Hart engines, and many other makes.

S. Jennings Racing will rebuild to as new any engine or develop an engine for competitive use.

We utilize all methods to deliver a perfect engine upon rebuild such as: magnaflux, pressure test, main line and cylinder hone, rod reconditioning and complete cylinder head services that are all performed in-house. Every engine that leaves is dyno tested for break-in and then tuned on current Stutska water brake dynos which use Depac data acquisition.
