Our silicone couplers are made from the same heat resistant embedded fibers as our silicone hose kitso you know they are durable and can withstand the toughest condits! Learn More

Cosworth High Performance engine assemblies the perfect basis your high performance application. Each version gone through countless hours of engineering evaluation to determine best combination of parts build specification; ensuring maximum reliable performance. Each Cosworth High Performance enginembly starts with new select components as foundation of performance build. Every block is thoroughly inspected before cylinders honed to perfection. We then balance rotating assembly that includes either a factory forged crankshaft or Cosworth Billet crank along with Cosworth Forged connecting rods; Cosworth Tri-Metal bearings Cosworth Forged Pistons. motorsport grade parts then professionally assembled by expert engine builders in Cosworth enginembly facility. Each High Performance enginembly includes a complete specification sheet listing critical dimensions along with a serialized plaque. maximum performance; combine with a Cosworth ported Valve Cylinder Head camshaft set.

Engine bearings one of most vital components within an engine are often overlooked when considering high performance upgrades. Performance engineered; multi-layer bearings generate less heat than normal bearings by reducing friction. Cosworth Race bearing sets feature a unique combination of design; metallurgy engineering to deliver performance in extreme condits. Cosworth Race bearings setsare available in sizes to accommodate most applications. Size 1 bearings a nominal standard size are used most applications. Size 2 bearings feature an additional .001 clearance should be used
when extra clearance is required.
Key Features
High strength overlay plate with reduced thickness better control less friction
Hardened steel backing on connecting bearings
Increased crush better retention
3/4 grooving on Main Bearings providing optimum supply
Tight consistent wall tolerances
Oversize chamfers where applicable
Flash plating eliminated improved heat transfer
Tested to over 1000 horsepower! Learn More

The piston is of most important components within engine. It be subjected to directional change up to times every second must withstand acceleration forces of 8500gs. Cosworth high performance forged pistons designed engineered to withstand this type of punishment still perform. Cosworth's pistons manufactured using same methods as Formula pistons include features such anti scuff skirt coating; ultra-strong pins; polished and patented antidetonation bands. Additionally; each application uses a unique forging to minimize weight ensure strongest possible piston design.
Key Features
Unique forgings each application
Xylan anti scuff skirt coating
Polished tops (reduces carbon build up relieves stress)
Manufactured from proprietary alloy (CosAl 010)
Ultra strong pin
Patented anti-detonation bands Learn More

Mishimoto Racing Thermostats will promote greater cooling efficiency throughout your engine. The Mishimoto racing thermostat will significantly lower high engine temperature produced by modified and upgraded turbo applications. Once the engine is fully warmed up the Mishimoto racing thermostat will open up at a lower temperature than standard thermostats; also allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures.
