Integrated Engineering Tuscan 155X22 Connecting Rods - Audi B9 3.0T EA839 Engines
THE TUSCAN ADVANTAGE
The Integrated Engineering Tuscan I-Beam design is IE's premium connecting rod technology, delivering unparalleled bottom-end strength for your high-boost build. Utilizing advanced software and design practices, these rods have been in-house engineered to target the weak points of the factory-installed rods specific to the Audi 3.0L EA839 engine. The outcome is an advanced connecting rod design that offers exceptional resistance to bending, optimized bearing stability, and extended fatigue life, ensuring dependable performance under demanding conditions.
LEADING FEATURES
- Innovative I-Beam design to withstand up to 1000ft-lbs of torque
- Offers incredible torsional stiffness without excessive weight
- Massive 22mm wrist pin sizing for reliabilty under high boost pressures
- In-house engineered specificially for the Audi 3.0T engine demands
- Perfect match for iE Spec JE Forged Pistons for ultimate strength
- Includes a complete set of six connecting rods
OPTIMIZED WEIGHT
Creating a strong rod is one thing. The real challenge is crafting a robust beam while maintaining a lightweight design. Integrated Engineering's unique I-Beam shape is the result of an extensive process to identify the high-stress areas placed on the rod in a high-performance 3.0T engine. The resulting design evenly distributes these high-compressive loads across the strongest parts of the beam. This painstakingly iterative practice puts the material strength where it's needed, and trims the fat where it's not. Enjoy the confidence in an incredibly strong rod that won't slow down your rotating assembly with unnecessary weight.
PRECISION MANUFACTURING
Strength lies in the details. iE Tuscan connecting rods are forged from vacuum-drawn 4340 chrome moly steel, then surface-peened for enhanced fatigue strength. Each casting undergoes rigorous dimensional and magnaflux inspections to ensure top-quality forgings. Precision machining and diamond honing achieve critical tolerances of approximately 250 millionths of an inch. Finally, the rod sets are meticulously balanced to match weights within +/- 1 gram of each other, delivering a high-quality connecting rod set straight out of the box.
iE SPEC JE FORGED PISTONS
To complement the strength of our connecting rod design, Integrated Engineering collaborated with the experts at JE Pistons to produce an equally robust iE Spec forged piston set. Extensive testing revealed that the factory piston compression ratio in the EA839 engine is susceptible to excessive knock in very large turbo/high-boost builds. In response, JE has developed a performance 3.0T piston forging with our optimized 10:1 compression ratio. These pistons boast additional features for high-performance builds, including Tuff Skirt coating, robust ring supports, sturdy 983M material forgings, and large 22mm wrist pins.
IMPORTANT NOTE: iE Tuscan Rods require aftermarket pistons with 22mm wrist pins.
