The Standard KO3 OE Turbo on the Peugeot 208 GTi comprises of a 37.8mm compressor wheel which makes it roughly capable of 230-240hp however the ECU will trim that power level back to around 210-220hp simply because the cylinder and exhaust gas temperature is too hot due to amount of heat the stock turbo puts out. The stock map sensor is 1.5 bar max so the the 1.8bar map sensor available from our store if youre looking to also upgrade that although this turbo should can manage approx 300hp and is listed as being capable of a maximum 330-380hp depending on your choice. The maxium fuel available on these engines without menthanol injection is 310hp so please bear that in mind. The stock 208GTi engine is capable of approx 280hp, after that forged pistons and con rods is advised. Another point to mention is 310hp generates approx 425nm of torque, see our clutch upgrade advice further down.
We have an exchange service which is where these prices start at or a complete turbo to suit your budget.
Upgrading the OE clutch would also be a sensible idea as they fail at 360nm. We would suggest fitting this paddle clutch although if your tuner has access to programming the BSI it is quite possible to stay under 400nm of torque and use a full face clutch. The last point would be traction is a huge issue for fwd cars so if you dont have one already then fitting a limited slip differential would be great, without it these cars tend to wheelspin from 0-90mph with this kind of power.
