Designed Through Technology
IE's Tuscan connecting rod sets for the VW VR6 engine 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 rigorously 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 leads 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.
IE TUSCAN 144X20 APPLICATIONS
2.8L VR6 with OEM & aftermarket pistons Engine Codes: AAA, AFP. BDF3.2L VR6 with OEM & aftermarket pistons Engine Codes: BJS
Are these are a direct replacement for my factory rods?
These rods fit VW VR6 engines when used with factory or aftermarket 20mm wrist pin pistons only. See the Fitment tab for a complete list of applications.
Is there a proper orientation to install the bearing tangs on our connecting rods?
We recommend installing the bearings tangs facing the exhaust side of the engine.
Are these connecting rods forged?
Yes, all Integrated Engineering Connecting Rods are manufactured from performance forgings. These forgings far exceed the quality of most factory rods that are typically made from powdered metal as a cost-saving measure.
Do these rods require any additional machine work for installation?
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.
Is balancing the engine required when installing these connecting rods?
Since IE rods are sold in balanced sets this is not required. For the extreme performance application, this can still be done if desired.
What is the maximum RPM limit of these rods?
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.
What are the most common reasons for connecting rod failure?
As one of 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.
