What is the benefit of using an oversize piston like this?

Oversize pistons are typically used during an engine rebuild when the cylinder walls have been honed or bored out to remove imperfections or to increase the engine's displacement. This 1.0mm oversize set allows you to restore the proper piston-to-wall clearance in a freshly bored block.

What does the 9.5:1 compression ratio mean for my engine?

A 9.5:1 compression ratio is a moderate increase over stock for many 2.0L TSI engines. It generally offers improved power output while still being compatible with premium pump gasoline in most applications, striking a good balance for performance builds.

What else might I need to install these pistons?

When installing new pistons, you'll typically need new connecting rod bearings, main bearings, and potentially new connecting rods if you are upgrading. It's also crucial to have a proper torque wrench and follow the manufacturer's recommended assembly procedures and clearances.

Product Details

This is a set of four forged pistons and rings from Carrillo, specifically made for the Audi 2.0L TSI engine. These pistons are designed as a 1.0mm oversize replacement, meaning they have a bore diameter of 83.5mm, which is useful when rebuilding an engine that has already been bored out or needs a slight increase in displacement. The compression ratio is set at 9.5:1, a common target for many performance builds that aim for a balance between power and pump gas compatibility.

Carrillo is well-known for making strong internal engine components, and these pistons are no exception. They are forged from high-strength aluminum alloy, which gives them the durability needed to handle the increased cylinder pressures and temperatures that come with performance tuning or rebuilding a high-mileage engine. The 22mm wrist pin size is standard for many performance applications, ensuring good compatibility with aftermarket connecting rods. This set includes the pistons and the necessary rings to complete the installation, making it a convenient package for engine builders.

When rebuilding your Audi's 2.0L TSI engine, especially if you're going beyond stock specifications, using well-built internal components like these Carrillo pistons is important for long-term reliability. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
