Calico Coated Race Bearing Sets

These bearings are the real deal coated bearings. Starting with premium ACL brand race bearings the base shells feature a hardened steel backing, with increased crush for better rotation. They have increased ovality to compensate for distortions at high rpm levels, and are designed with a high strength overlay plate for maximum fatigue resistance. All of this is covered up with a professionally applied coating by Calico, giving a truly high performance bearing from the coating all the way to the outer shell. They are available in standard or +.001" extra bearing clearance for the most extreme applications.

Integrated Engineering Billet 4140 Standard Main Caps

These VW 4 cylinder main caps are carefully crafted, in-house, from USA 4140 alloy steel. They provide extreme rigidity to the main bearing and crankshaft, which is a necessity for high horsepower engines. In addition, the large profile and high strength material is much stronger and stiffer than the factory main caps.
Requires machine work including line bore & hone for fitment. More info here
Integrated Engineering Billet 4140 Tall Boy Main Caps

These main caps are specifically designed to work with a crankcase bedplate/girdle. Typically, the installation of those products requires machining small spacers, which go between the main cap and the girdle, bringing it up to the same level as the pan rails and typically are very difficult to machine to the correct height. IE Tall Boy Main Caps ship standing slightly proud of the pan rail to be machined level with the pan rail, resulting in a perfectly flat surface for the installation. The large profile and high strength material is much stronger and stiffer than the factory main caps.

Integrated Engineering 1.8T Torque Plate

Boring your engine with a torque plate is one way to ensure the cylinders of your high performance engine are as round as possible. This plate simulates a cylinder head being bolted onto the engine, distorting the block into the shape it will be in with the head on. Boring it in this state ensures that the bores are actually round with the head on.

Integrated Engineering 1.8T Timing Belt Gear Dowel Pin Kits

One of the major weaknesses of the 1.8T 20V platform is that the timing belt system is slightly under specced for the large load placed on it by the 20v head resulting in a keyway that has been known to shear off the crank pulley. IE Dowel Pin Kits uses a 7200lb shear strength alloy dowel pin through the joint to hold the load. Our kit allows the crank to be successfully modified even in the car. Featuring a brand new OEM timing pulley, which has been drilled, reamed, and then chamfered in our CNC Milling center. This ensures that the bore is placed right on the money and square to the end of the crankshaft. The kit includes a pulley, drill bit, reamer, high strength alloy steel dowel pin and 2 page instructions with pictures.

Integrated Engineering has a huge selection of Forged Pistons including JE, Mahle, and Wiseco available in various compression ratios, strokes, and bore sizes. Whatever piston combination you need, we have a set to meet your budget. Don't see what you need? We can custom order anything!
JE pistons

JE pistons are a great upgrade for someone looking to build a stout, reliable engine. JE's 2618 alloy is stronger then most other pistons made from 4032, and are specifically engineered for extreme applications, and is why we chose to use them in all our race engines. Dish requires no deburring or preparation.
JE's use 20mm wrist pins so they will require a set of rods with 20mm pins to match.

Mahle Pistons

Mahle PowerPack Pistons are extremely high quality and an excellent choice for those looking to increase strength while maintaining a lightweight piston with oem fit and finish. Mahle pistons provide improvements in strength over OEM pistons without some of the sacrifices sometimes found in other forged pistons. Precision forged from 4032 alloy, a low expenasion rate aluminum. They all feature forged side reliefs, reducing the weight of the overall package. They also use slipper skirt designs, reducing friction and further reducing weight. Mahle PowerPack pistons feature ultra flat ring grooves, which promote excellent ring seal and most importantly reduce the chances of micro-welding during break in. Every set of Mahle PowerPack pistons comes with their exclusive Grafal skirt coating, which is not only anti-friction but also offers impact absorbing qualities, reducing piston noise and decreasing stresses in the piston skirt. These have 20mm wrist pins so they will require a set of 144x20mm rods to match.

Wiseco Pistons

Wiseco pistons are very high quality cost effective piston, machined and forged in USA using state of the art facilities. Wiseco Pistons are forged using 4032 alloy, this alloy isn't quite as strong, but has less thermal expansion, so motors can be built tighter. This is a good thing in those that rely heavily on knock sensors. These pistons are an exceptional value. These have 20mm wrist pins so they will require a set of 144x20mm rods to match.

JE Stroker Pistons

Integrated Engineering Custom JE stroker pistons are designed to be used when over boring the block specifically for stroker conversions. This increased displacement yields more power on the same boost, less chance of detonation at a given power level (Lower peak cylinder pressures) and faster spool. JE pistons are a great upgrade for someone looking to build a stout, reliable engine. They have 20mm wrist pins so they will require a set of rods with 20mm pins to match.

Integrated Engineering Crankshaft Girdle/Bedplate kit for 06A 1.8T
Under increased RPM horsepower, and torque your block can begin to flex, causing severe main bearing wear or even a broken crank or block. Reinforcing the block is a necessity for extreme applications. This girdle kit uses a 3/8” specifically designed steel plate bolted to the underside of your block increasing lateral support and preventing flexing under high power use. The girdle plate bolts to all of the main journals, using the supplied custom extended-length ARP main stud kit. It is then sandwiched between the block and the oil pan to keep the block from flexing. This kit includes all lengthened hardware needed to install the girdle plate. Spacers are included for use with factory main caps, however IE “Tall Boy” billet main caps are a highly recommended for high horsepower builds.
