REDS Racing has created the WRX Corsa Lunga™ engine following the philosophy of product innovation, high quality, high performance and reliability. Everything that makes the WRX unique today is an extraordinary step forward.  

20k RPM OF USABLE TORQUE 
The WRX faetures Extra Long Stroke geometry 16x17.3 mm, 5 scavenger ports and a single exhaust port cylinder sleeve and works with the crankcase to deliver more low-to middle-range torque with less fuel consumption. The engine has been designed to develop an incredible wide RPM range of usable torque, which makes the WRX Corsa Lunga one of the fastest engine worldwide.

A DIAMOND IS FOREVER 
We decided to improve REDS Racing engines line and provide the all-new WR Line engines with a DLC Coated crankshaft and backplate for improved engine durability. The crankshaft can last approximately 3 times more than a coventional steel crankshaft thanks to the extreme hardness of the diamond coating. Even the conrod life is lengthened about 50%.

THE NEW COOLING SYSTEM 
The brand new cooling system has been specifically developed to widen the operating range so that the engine can work well in extremely hot conditions. Furthermore, the new cooling system has been created to guarantee a more consistent tuning in every track condition.

ADVANCED CARB SYSTEM 
The revolutionary carb features a differently positioned top end needle, rather than a conventional carburetor pointing diagonally upwards. The REDS HCX is horizontally positioned lower down making REDS the only company with this set-up: greater idle stability, more precise tuning, easier access to high speed needle, higher mid/top range power. 

REDS Horizontal carburetor has been provided with a revolutionary off-set GEN 2 venturi to assure improved fuel mileage and higher torque. The REDS HCX carburetor provides more efficient fluid dynamics for an even greater tuning stability.

HANDMADE, TUNED AND ASSEMBLED 
The new engine is hand-tuned with a silicone-filled, balanced and tuned crankshaft by M. Rossi. Every single engine is hand inspected and compression checked inside REDS Racing headquarters by Mario and Marco Rossi to achieve the highest quality standards. This is core to the values that makes the WRX different from any other engine brand on the market.

ANTI-DIRT SEALING SYSTEM 
The new cooling head anti-dirt sealing system keeps the engine clean in a critical area between the cooling head and crankcase. The redesigned crankcase provides easier maintenance and a cleaner engine for longer life.

ADVANCED ENGINEERING
REDS products are developed using tools to analyze Engine Dynamics, Computational Fluid Dynamics (CFD) and Stress Analysis (FEA).
