Seat Leon 1.8 TSI Gen3 – Stage 3 IS38 turbo (Golf 7R turbo) 98RON

Nothing beats a 1.8TSI engine with the performance of a Golf 7R. This is why we use the turbocharger unit, IS38, from the Golf MK7 R 2.0 TSI. It is a direct bolt-on replacement to the stock unit in the Leon. This upgrade applies to manual gearbox models. The DSG7/DQ200 gearbox versions require torque limitations in order for the upgrade to work so as to avoid destroying the transmission.


Upgrade specifications

  • Stage 3 ECU remap for IS38 turbo
  • 98RON fuel
  • IS38 turbo
  • Upgraded full exhaust
  • Optional: Intercooler kit


Performance results

  • Maximum horsepower: 356.7 PS (stock power based on model specs is 180 hp)
  • Maximum torque: 460 Nm (stock torque based on model specs is 300 Nm)
  • 100 – 200 km/h acceleration time: 9.8 seconds

    What else do you need to be able to put the IS20 turbo of a GTI into a Leon with IS12? Do you hace gearbox remap and ecu remap for the dq200 and the is20? do you ship to Mexico?

    Adolfo! Speak of the devil, we are working on that upgrade right now. I am not sure if you are reading our minds, but it makes total sense. 1.8 TSI gen3 receiving 2.0 TSI gen3 IS20 turbos is probably the next most popular upgrade you are going to see.
    So far the DQ200 gearbox seems to be handling it without issues. Torque needs to be under control to avoid damaging it.
