What are the best modifications for maximizing horsepower on the Toyota Supra?

I recently purchased a Toyota Supra and I want to increase its horsepower. I've heard that there are a lot of modifications available, but I'm not sure which ones would be the most effective. Can anyone give me some advice on what modifications would be best for maximizing horsepower on the Toyota Supra?

Adding a cold air intake and a cat-back exhaust can give you a noticeable increase in horsepower and also improve the overall performance of your Supra.

Installing a performance ECU or engine tuning can also greatly improve your Supra's horsepower. Just make sure to research and choose a reputable brand.

Upgrading your turbocharger and intercooler can greatly increase your Supra's horsepower. However, this can be a more expensive option and may require additional modifications to support the added power.
