Designed Through Technology
IE's Tuscan connecting rod sets are the best rods available for your European engine due to quality, custom application specific design, and thorough testing. Each Tuscan design is different from any other design because they are custom-crafted and optimized by our engineers using the latest CAD and FEA software. This is in contrast to the industry standard which simply resizes standard designs to fit new engines. Each application is vigorously tested in our in-house engine test cell. We have gone the extra mile to design specific big ends for each application, keeping the bearing in place and reducing chances of failures. This results in a connecting rod that is uniquely strong and light, for the ultimate in performance and reliability.
Application Specific Engineering
Each model is detailed out with a unique feature set that ensures proper operation within the unique demands of that engine. There is a particular emphasis placed on providing a stable foundation for the connecting rod bearing. By providing a stable platform for the rod bearing, much higher reliability is possible. For that reason, the feature set is not consistent across all models of IE Tuscan rods.
Torture Tested Reliability
IE Tuscan rods for turbocharged applications feature a robust I-Beam design for incredible bending and torsional stiffness. Additionally, an extensive iterative process lead to the unique Egg shape of our rod beams, which lowers stresses as much as 20% compared to less evolved designs. This shape very evenly distributes the high compressive loading from a turbocharged engine onto the connecting rod beam. We then validated this success with over 18 months of field testing, powering numerous 4 cylinder VW / Audi engines with over 1000 bhp! In addition to being tough, IE Tuscan rods are also designed to minimize unnecessary weight on the connecting rod for an ultra balanced weight to strength ratio. Our engineering staff has spent countless hours trimming the fat- leaving exactly what is needed to get the reliability you want, with the weight you don't.
Finished And Quality Controlled In USA
This level of attention to detail is mirrored in the manufacturing details as well. Each set of Tuscan connecting rods are honed in the USA to tolerances of around 250 millionths of an inch! This ensures amazing bearing reliability you really cannot find elsewhere in this price range. These rods are as round and true as any rods money can buy.

These rods fit several VW/Audi engines that use a 144x20mm rod. Due to the wide range of engines these rods fit, please see the applications table above.
We recommend installing the bearings tangs facing the exhaust side of the engine.
Yes, all Integrated Engineering Connecting Rods are made from tough and durable 4340 forgings. These forgings far exceed the quality of most factory rods that are typically made from powdered metal as a cost-saving measure.
At a minimum, you should use a new set of connecting rod bearings when installing rods. We also offer several install kits to make this process as easy as possible. For more information on rod bearings and install kits, please see the install kits section above.
IE connecting rods are delivered to you in "ready to install" condition. Other engine machine work may be required though when rebuilding an engine, such as decking the block or boring and honing cylinder walls.
Since IE rods are sold in balanced sets this is not required. For extreme performance application, this can still be done if desired.
The average weight of a single rod with bolts is 574 grams. Rod weights can vary slightly per set. More technical information can be found in the basic dimensions section above as well.
The maximum RPM limit can be affected by many factors. In this application, we suggest not exceeding 8500 RPM with ARP 2000 bolts. If you plan on exceeding this RPM level, consider upgrading to ARP 625+ bolts.
Generally speaking, high RPM conditions put the most stress on rod bolts as the rod and cap are literally being pulled in opposite directions. If you plan on pushing your engine far past factory redline or 8500 RPM we would suggest upgrading to 625+ ARP bolts.
Rifle drilling is not required. However, we do strongly recommend it for daily driver and high mileage applications. Rifle drilling has been proven to extend wrist pin and bushing life and has also been utilized over the years in several VW/Audi factory connecting rods.
Many high horsepower VW and Audi vehicles use IE rods. We rate our 4 cylinder H-beam rods for 700+ HP/ft-lb TQ. If you are planning on exceeding those levels we recommend upgrading to our Tuscan I-beam Rods (part number IERTVA1).
We stock several high-quality piston options to suit your specific needs and to match our connecting rods. To see what we have to offer be sure to see our piston recommendations section above.
As one of the highest stressed components in the engine, there are several things that can contribute to a failure. The most common failure is caused by improper installation followed by improper tuning. We recommend that you seek professional help for both installation and tuning. Oiling system health is also essential to ensuring safe engine operation. Momentary oil starvation can result in spun rod bearings and engine failure. In extreme applications also be sure that you are using heavy duty wrist pins. On many of the pistons, we offer we either include stout wrist pins or offer them as an upgrade.
