What con-rods were installed in the 2.0L TFSI?

To start at the beginning: the trapezoid con-rod

Time and again, the con-rods were modified over the years. The piston pin diameter was constantly increased from 20 mm up to 23 mm. The upper con-rod eyes in the engine of the Golf MK7 had no bushing any longer; the piston pin was only coated with DLC. From the outset, all TFSI con-rods were so-called trapezoid con-rods. For this, the piston had a matching trapezoidal recess. This trapezoid makes it difficult simply to install reinforced con-rods, since most con-rod manufacturers do not offer any trapezoids.

It’s the combination: con-rods and pistons for more performance

This is why it is better to install a con-rod/piston combination right away if you want more performance. This also facilitates the lowering of the compression ratio via the piston and ensures that the con-rods match the piston perfectly. Another change came with the chain engine (EA 888 model series). A completely new engine concept was developed, and the width of the big end of the con-rod was reduced for reasons of weight. Fortunately, the dimensions of the con-rod bearings remained the same. In the newer 1.8 TSI engine, the displacement was reduced, namely by way of a different crankshaft with less stroke. The bore and the con-rod were fortunately not changed.

Overview of all con-rods installed in the 2.0L TFSI engine

We compiled an overview of the different con-rods in the 2.0L TFSI engine to make it easier for you to find your desired upgrade con-rod. The con-rods are still one of the weakest links in a turbo engine, since in series development they must not just be inexpensive but also reduced in weight so as to save fuel and thus emissions.

Tuning structure of a 2.0L TFSI engine block

The 2.0L TFSI engine (EA113) has a cam belt turbocharger and direct injection. The following vehicles are equipped with this engine:

  • VW Golf MK5 GTI
  • VW Golf MK6R
  • Audi A3 8P
  • Audi TT 8J
  • Audi A4 B7

The purpose of this description is to show you the right tuning parts for different performance goals.

The engine block of the 2.0L TFSI



The part number of the 2.0L TFSI blocks always starts with 06F. The engine code is located on the flat surface toward the cylinder head and to the right next to the knock sensor.

The engine codes are:


Main bearing/bearing shells of the 2L TFSI



The VAG 4-cylinder engines of the 06F block have five bearing supports with thrust washers. Most bearing supports are made of cast iron. From 500 hp and up, the original supports should be upgraded to IE billet steel. For this, the bearing line of the crankshaft must be newly honed.

The crankshaft in the 2.0L TFSI



All 2.0L TFSI engines have a stroke of 92.8 mm. The cogged belt pulley is fastened with a large bolt (crankshaft bolt). On this crankshaft sprocket, the crankshaft damper is fitted with a 6-hole connection. A sensor wheel is sitting on the crankshaft that is used for positioning the crankshaft. It is very important not to bend this wheel. If it is removed for some reason, it must be replaced completely (one-time use).

(Most crankshafts are replaceable, with the exception of the Audi A4 B7 Quattro with automatic transmission.)

2.0L TFSI con-rods



Alle 2.0L TFSI Pleuel haben eine Länge (Bohrungsmitte zu Bohrungsmitte) von 144mm und eine Lagerbreite von 24,90mm. Es unterscheiden sich nur die Kolbenbolzendurchmesser zwischen den Motorcodes von 20mm bis 23mm. Die häufigste Größe für Standard Motoren ist 20mm (z.B. VW Golf 5 GTI). Der BHZ (S3) und CDL Motor haben schon etwas stärkere Pleuel gegenüber den Vorgängern. Nichts desto trotz bleiben die Pleuel immer das "schwächste Glied in der Kette" und müssen als erste Maßnahme gegen upgrade Pleuel getauscht werden.

2.0L TFSI pistons



Most pistons are forged; still, they are not as robust as tuning forged pistons. The original bore size is 82.5 mm. The compression ratio varies from 9.5:1 to 10.0:1, depending on the engine code. Our innovative compression ratio calculator allows you to filter for your engine code, and the compression ratio is automatically displayed.

2.0L TFSI upgrade to 350+ hp

It is generally known that the con-rods are a weak point in the engine. With this performance update, you should replace the con-rods. Although it is possible to drive with performances of over 350 hp, the original con-rod might rupture – it depends on the engine and the software tuning. Then the result is a hole in the block, and the engine cannot be saved. Before you take the risk of severe engine damage, you better replace the original con-rods by reinforced ones.


There are two plug & play con-rods available for use with standard pistons. With high mileage, we recommend the use of drilled con-rods (riffle drilled) in order to supply the piston pin with oil during a long service life. Original pistons always require trapezoid con-rods (trapezoidal design on the small con-rod eye):

For this performance, it is not imperative to replace the pistons. Assuming, of course, that there is no damage whatsoever and that the cylinder walls are in good condition.




An important fact is, however, that many bolts are stretch bolts that can be used only once. Once they have been removed, they must be replaced. ARP studs and bolts, by contrast, can be reused any number of times and offer more safety in terms of higher loads and internal cylinder pressures.

You’ll find the matching ARP studs and bolts for your upgrade here:

2.0L TFSI upgrade to 400+ hp



In order to ensure a reliable operation in this performance class, there is an urgent need to upgrade the con-rods and pistons. Most pistons use a 20 mm piston pin in connection with 144 x 20 mm con-rods. 



In addition, the crankshaft bolt should be replaced with an ARP bolt in order to prevent awful engine damage.



Wir empfehlen dringend Haupt- und Pleuellager zu tauschen. Der Vorteil ist die TRI-Metall Zusammensetzung welche die hohen Lagerbelastungen widersteht.

We strongly recommend replacing the main and con-rod bearings. The benefit of the tri-metal composition is that it withstands high loads on the bearings.

2.0L TFSI upgrade to 500+ hp



For the last upgrade stage of your 2.0L TFSI engine, you also need modified main bearing supports. The original main bearing supports are cast and have an increased engine movement compared to the upgrade IE billet supports made of high-strength alloy steel. In addition, they reduce the wear on the main bearings. If you want to play it safe, you should install our main bearing girdle.


Important: The products from the previous upgrade are still required.
