Seat Leon 1.8 TSI Gen3 – Stage 3 IS20 turbo (Golf 7 GTI turbo)

What could be better for any 1.8TSI owner than getting 2.0 TSI performance out of his car? This setup uses the VW Golf 7 GTI turbo on the 1.8 TSI Gen3/MQB platform. The essence of the upgrade is to produce 2.0 TSI stage 1 results, only from a 1.8 TSI engine with an upgraded downpipe.

About the upgrade

The stock turbo on the Seat Leon 1.8 TSI MQB is the IS12. The IS20 is a direct bolt-on replacement. Based on the engine’s performance as a stage 1 and stage2 on the stock turbo, it is a natural development in its evolution and a key step before the IS38 turbo kit. The IS38 turbo kit is not DSG7 friendly, which effectively limits its application to manual gearbox cars.

Upgrade specifications

  • 98 RON fuel
  • IS20 turbo
  • Upgraded downpipe
  • DSG7 gearbox – friendly

Performance results on a Dynapack dyno

  • Maximum Torque: 41 Kgm (25 Kgm measured as stock), gains 16 Kgm

Street performance is even more impressive than the numbers alone. Stay tuned for videos coming up!
