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 Power: 300 whp (173whp measured as stock) , gains 127whp
  • 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!

        Thank you! No one wants to try this “new” modification in my country, so I´m trying to investigate all the issues and the extras, if needed, for the installation.

        Thank you for sharing information.

    • Ger Mour Posted July 22, 2016 4:05 pm

      The car run fine with no issues at all.

        Thanks, has the owner done any additional mods after this? I’m looking at doing the same upgrade on my 8v A3 1.8tfsi.
