Audi A3 1.4 TSI125 – big turbo kit TD04

This turbo kit is crazy. Starting from 125hp, it boosts performance up to 300+ hp at the flywheel, which is almost 200% more power than stock.
Big turbo kits on 1.4 TSI 125hp engines (CAX code) are usually very difficult. Because they push the stock ECU calibration and engine setup to many times as much power.
This Audi A3 8P behaves much more like its bigger 2.0 TFSI brothers with the TD04 turbo kit.
The stock connecting rods are strong enough to withstand very high levels of torque. However, the stock pistons are a problem at this power so upgraded ones were used instead. The Water-methanol injection kit makes sure that high levels of boost can be used without compromising engine safety, at the stock compression ratio.
