What are the best modifications for increasing the horsepower of a Toyota Supra?

I'm looking to upgrade my Toyota Supra, but I'm not sure where to start. What are the most effective modifications I can make to increase the horsepower? I want to make sure I'm getting the most bang for my buck.

For the best bang for your buck in terms of horsepower, I would recommend investing in a performance exhaust system and a cold air intake. These two modifications alone can give you a noticeable increase in horsepower.

If you're looking for significant horsepower gains, I would suggest upgrading your turbocharger. This can be a more expensive modification, but it will definitely give you a noticeable increase in power.

Don't neglect the basics when it comes to increasing horsepower. Regular maintenance, such as changing spark plugs and air filters, can also help improve performance.
