400BHP Toyota GR Yaris

Another Toyota GR Yaris in with us for some work, we modded this car last year and now it has a new owner. The new owner reported a rattle coming from the turbo which turned out to be a dodgy wastegate, so we swapped it for a new Turbozentrum hybrid turbo and fitted one of our Whifbitz stainless steel exhausts along with some map tweaks on our dyno.

The GR Yaris has the following modifications:

  • Whifbitz stainless steel exhaust
  • Whifbitz GPF resonated delete pipe
  • Whifbitz decat pipe
  • Turbozentrum hybrid turbo
  • Syvecs ecu
  • Kelford valve springs
  • Kelford 266/274 camshafts
  • Wagner Tuning intercooler
  • Eventuri intake kit
  • Forge Motorsport oil cooler kit
  • CANchecked display
  • Maxton bodykit
  • Ohlins coilovers

Its now making a nice useable 337whp which is an estimated 403bhp.
