I am seeking to increase the power output of my E46 323ci.

I own a 2000 323ci equipped with the M52TUB25 engine. I have been extensively searching for suggestions on how to enhance its power, but unfortunately, I have not come across any definitive recommendations. Does anybody have any proven and verified ideas?

Consider the standard options: sell the automobile and get a vehicle with a larger engine, or alternatively, install a turbocharger on the existing car.

Attach a turbocharger to it.

Do you know which turbocharger offers the most optimal outcomes? I am a complete novice in this field, hence I have no knowledge or understanding.

I plan to replace the M54B25 intake and make some adjustments to the DME settings/map in order to get an additional 20 horsepower.

Greetings! To enhance the performance of your 2000 323ci with the M52TUB25 engine, it is advisable to enhance the intake and exhaust systems in order to optimise airflow. Optimising the engine with a performance chip or software may help augment power output. These improvements are widely used and have been proved to effectively enhance performance, as many enthusiasts have discovered.

The Garnett gt25/60r is a turbo that is often used in low boost conversions. It offers respectable performance considering its budget.
