Product Summary


  • IE Tuscan I beam connecting rods
  • Mahle 81.5mm bore 8.5:1 CR forged pistons
  • OEM main bolts
  • OEM thrust washers
  • Mahle Motorsport rod bearings
  • Mahle Motorsport race main bearings 



Once the OEM VW/Audi block is cleaned and multi-point inspected, an Integrated Engineering torque plate is used to secure the block into the proper shape during the boring and honing process. This guarantees true round cylinders and results in precise piston to cylinder wall clearances necessary for long engine life. The block deck receives a fresh machined surface for a proper head gasket seal and strong compression. The maincaps are installed and measured to exacting specifications using new OEM main studs ensuring exact roundness for proper crank stability.  The rotating assembly is then installed with Integrated Engineering forged Tuscan I beam rifle drilled connecting rods, Mahle 81.5mm 8.5:1CR forged pistons, Mahle Motorsport rod and main bearings, and a polished OEM crankshaft by an IE expert engine builder. All clearances are recorded on a multi-point critical dimension check list with all measured clearances that is included with your block, along with an instruction & care pamphlet.




  • IE Tuscan I beam Connecting Rods

IE Tuscan I beam rods are the premium benchmark connecting rod application offering industry leading strength to weight ratio and support up to 1000BHP!
The Tuscan design is custom-crafted and optimized by our engineers using the latest CAD and FEA software then vigorously tested in our in-house engine dyno and chassis dyno test cells. This results in a connecting rod that is uniquely strong and light, for the ultimate in performance and reliability. With the included rifle drilling option, oil is forced to the wrist pin by means of a small hole drilled through the rod vertically. This reduces friction on the pin and pin bushing, thus reducing wear and further extending engine life.

  • Mahle Motorsport Forged Pistons

The included set of forged stroker pistons make for a stout reliable engine for daily driving, road racing, drag racing, or full out competition racing. Mahle pistons utilize weight optimized aluminum pistons manufactured from high-temperature resistant aluminum silicon alloy. This alloy along with Mahle's refined design and production technology enable an ideal combination producing pistons with low weight and high load-bearing capacity. Mahle pistons are treated with their own GRAFAL skirt coating, this greatly reduces the skirt to wall surface friction and increases scuffing resistance and lower engine noise.

  • Mahle Motorsport Rod & Main Bearings

Mahle Motorsport manufactures the highest quality race bearings available proven time and time again by race engine builders including F1 race teams. With many special features, these bearings have great wear characteristics and added durability for long engine life. Mahle uses a proprietary tri-metal blend to provide a stiffer bearing under high load use, which is necessary for race engines. Each bearing is designed with state-of-the-art software for the ideal oil film thickness, which adds reliability and greatly reduces the chance of spinning a bearing.

  • Crankshaft Re-manufacturing

Your supplied core or new OE crankshaft receives specialty machine work before engine assembly.  The oil holes are chamfered and the journals are polished for improved oiling properties before receiving a multi-point critical measurement test to ensure long operating life of the rotating assembly.



Each block is finish painted with durable black enamel and packaged inside a specialty engine bag with a desiccant pouch to remove any moisture that may accumulate during the shipping process. They are then securely bolted into specially manufactured shipping crates ensuring there is no damage.
