1.8T Tuning: Block and connecting rods
Here you'll get all the info you need to get to 500 PS and beyond with your 1.8T engine block and connecting rods. We show you where the engine is installed, how the block is built, its bearings, crankshaft, pistons and connecting rods and more! You'll also learn which tuning parts you need for your 1.8T engine to get the maximum performance out of it. There's something for every performance goal.

The engine block of the 1.8T engine
There are two different engine blocks. The 058 engine block was installed up to the production date of May 2000. In the Audi A4 B5, it is longitudinally mounted only. It has an internal intermediate shaft and an external water pump.
06A engine blocks, on the other hand, have no intermediate shaft, and the water pump is driven by the cam belt. They are installed in all vehicles with transverse engines.
1.8T engine main bearing/bearing shells
The crankshaft of the 1.8T engine
All 1.8T crankshafts have a stroke of 86.4 mm. They are made of cast iron or are forged. There are two different wheels used to determine the engine speed.
The con-rods in the 1.8T engine
All 1.8T con-rods have a length (hole center to hole center) of 144 mm and a width of 24.9 mm.
- 06A engines have a 19 mm piston pin (except 225 PS models that have a 20 mm piston pin)
- 058 engines all have a 20 mm piston pin
The 1.8T piston
This is how the upgrade to 300+ PS will succeed.
As of a desired performance of 300 PS, we recommend the use of upgrade pistons and con-rods. This combination only works when the cylinder walls are in good condition, though. You get matching combinations of pistons and con-rods for your 1.8T engine from us.
Con-rods with oil drilling hole:
The oil drilling hole is a hole that is present from the small to the large side of the con-rod (riffle drilled). Thanks to this additional oiling, the piston pin has a considerably longer service life.

His first car was a Polo Mk1 with a 40 Weber twin carburetor and 129 PS (95 kW). His second was an Audi 50. Today Bartek tunes Lamborghinis to 1000 PS (735 kW). Even as a young boy, Bartek disassembled vehicles and put everything back together better. He wrote his high school diploma with oil on his fingers. The trained automotive mechanic with a focus on engines and gearboxes was determined to go into motorsports. In his 10 years in Formal 1, he supervised 73 races, including as engine mechanic for Ralf Schumacher at Toyota. Since 2010, he has dedicated himself fully to his company BAR-TEK® and helps his customers to bring VW and Audi engines to peak performance.

What do you folks do about installing cracked rod bearings, I have been building engines for over 40 years and haven't ever seen lock tangless bearings, is their a special way to install the shells in the rod

Hello Tim, we don´t know any cases where the rod bearings are cracked.
