Hi everyone, I have a BMW 118i 2019 with the 3-cylinder B38 engine, and I need to replace the turbo because of the wastegate.

does anyone suggest going for a bigger turbo and tune to this engine or a better turbo to avoid this issue coming again? or stage 1 is the max this engine can handle ?

thank you

The B38 engine can handle a bit of tuning, but it’s not built for high-output mods. A slightly upgraded turbo, like a hybrid or a direct bolt-on from a trusted manufacturer, could be a good middle ground. Pair it with a Stage 1 tune for improved performance without over-stressing the engine. Going too big on the turbo might strain the internals, especially if it’s your daily driver.
