Upgrade turbo - 1.8T - 270hp. 

Upgrade Turbo – 1.8T – 270 hp
This upgraded 1.8T turbocharger is a solid and thoroughly tested choice for anyone looking for a significant performance increase without compromising reliability. It fits directly onto the original exhaust manifold and downpipe, making installation simple and trouble-free. The intake size is 51 mm instead of 45 mm, meaning you will need a different intake hose – which you can find right below the product.
We have sold a large number of these turbos over the years, and customer feedback is consistent: strong performance, stable operation, and high quality. The turbo delivers up to approx. 270 hp with proper setup and is one of the most popular choices for the 1.8T platform.

Specifications / quality:
– The turbo is balanced on a VSR machine (same type of balancing as OEM)
– Journal-bearing construction like the K04, designed for approx. 270 hp
– No issues with axial play or imbalance when supplied with proper oil and cooling
– Max recommended boost pressure: 1.4 bar
