Product Summary

CONNECTING ROD TECHNICAL DETAILS

Tuscan connecting rods 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.

140X21MM for Custom Pistons

These connecting rods feature a 140MM center to center length, which is designed for use with the included custom pistons only. 

Designed Through Technology

Tuscan connecting rods represent the leading edge of technology for bottom end strength, reliability, and light weight. Our Engineering staff utilizes the most modern technology to optimize these rods to a level never before seen at the enthusiast level.  Breaking away from the status quo, our Engineers go above and beyond by individually optimizing each connecting rod application. 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.

For that reason, the feature set is not consistent across all models of IE Tuscan rods.  

Engineered Performance, 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. 

OPTIONAL RIFLE DRILLING

To keep wrist pin wear at the minimum, all of our forged rods are available in a rifle drilled option. Rifle drilling forces pressurized oil through a small orifice placed vertically through the rod and further lubricates the pin and bushing. This extra oiling causes less wear and friction between the rod and piston and increasing the life of the internals. We highly recommend the rifle drilling option for street-driven cars, as they typically see more mileage put on them, but works well to extend pin life on any setup.  You can select the rifle drilled option at an additional $25.00 per rod. 

PISTON TECHNICAL DETAILS

The included set of forged JE pistons for the S54B32 engines is made to IE specs, with the options for standard or +.5mm bores, both standard high compression ratio (11.5:1) or low compression for turbo use (9.0:1). JE is the industry leader in forged racing pistons, seen in many racing applications including Nascar. These pistons are made from JE's 2618 alloy, which is much stronger than the 4032 alloy commonly found in forged pistons. JE also offers the shortest lead time on custom pistons. There is several options available for bore, stroke, compression ratio, and additional features. These pistons all come standard with 21MM wrist pins, which can be used with Integrated Engineering 140x21MM connecting rods. All pistons include rings, wrist pins, and wire locks. Pistons take 2-3 weeks for manufacturing, and another 1-2 weeks with coatings.

TIPS FOR CHOOSING PISTON OPTIONS

Compression Ratio

Lower compression ratios are recommended for higher boost applications. When using a middle sized turbo on a street car, compression ratios around 9.0:1 are recommended. For high performance naturally aspirated builds, 11.5 is recommended. Custom compression ratios are also available- please contact us to order.

Bore Size

Factory bore on the S54 engine is 87MM. Increasing the bore will increase displacement, thus increasing power. Along with that, boring the engine will allow you to set the piston-to-wall clearances properly. Boring the engine out is always recommended. If you start with the maximum bore, you will not be able to remachine the block if any damage is caused to the cylinder walls. 

Tool Steel Wrist Pin Upgrade

The tool steel wrist pin option is to upgrade from the standard mild steel pins, to JE's thick wall tool steel wrist pins. They are recommended for 600+ WHP.

Skirt & Dome Coatings Upgrade

There is two coating options that we offer with the JE pistons- Thermal Barrier Crown, and Tuff Skirt. The Thermal Barrier crown coating is applied to the top of the piston, and is designed to keep heat out of the piston, and deflect it into the combustion chamber. This will increase exhaust gas velocity, as well as extend piston life. The Tuff Skirt coating is an anti-friction coating applied to the skirt of the piston. This coating will help reduce wear on skirts and cylinder walls.

All sales on custom pistons are final, no returns will be accepted. Please contact us before purchasing with any questions!

FAQ


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 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. 


What other parts will be needed to install my new IE connecting rod set?


At a minimum you should use a new set of connecting rod bearings when installing rods.


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 extreme performance application this can still be done if desired.


Do I need rifle drilling?


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.


What are the most common reasons of 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 save 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.
