How can I upgrade the power of my Toyota Supra's engine?

I recently bought a Toyota Supra and I am looking to upgrade the power of its engine. What options do I have and how much would it cost me?

One option could be to install a performance intake and exhaust system. This can improve airflow and increase horsepower. However, it can be costly and may also require an ECU tune for optimal results.

Another option is to upgrade to a larger turbocharger. This can significantly increase power, but it may also require additional modifications to the engine and drivetrain. Be prepared for a hefty price tag.

If you're on a budget, you could also consider a piggyback or stand-alone engine management system. This can allow you to tune your engine for more power, but it may require some trial and error to find the right settings.

Don't forget to also upgrade your brakes and suspension to handle the additional power. And make sure to consult with a reputable mechanic or tuner for personalized advice.
