What size external wastegate should I use on my vehicle?Updated 3 months ago

This is a complex question that should, ideally, be answered by the people building the exhaust portion of the turbocharger kit and the person doing the tuning on the vehicle. Factors that need to be considered include engine displacement, fuel type being used, available location of Wastegate mounting (and position/angle), intended max RPM of the engine, number of turbochargers on the vehicle, number of wastegates being used, and the desired boost levels/range that the vehicle will operate in (High and low boost). All of these factors should be considered when selecting the correct Wastegate size for the application.
