BAR-TEK® tips:
For vehicles with high power we recommend 102 octane fuel. This reduces the knocking of the engine, giving it more power. Turbocharger and engine should not be too old and in good condition. Also check the red pressure hose on the turbocharger. This is often leaking as it does not tolerate the heat from the manifold. Our Forge silicone hose can help!

To drive 400 PS, you have to replace your connecting rods with H-beam connecting rods and forged pistons. For this we have a complete all-round carefree kit of connecting rods and pistons! A sports clutch kit is also required. For the exhaust you should use a 76 mm exhaust system. To keep the oil temperature in a healthy range, an oil cooler must be installed!
