Intake and Exhaust - Note that on their own these mods will NOT ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction and you will hit a restriction with your mods and upgrades.Fast road cams are one of the most significant mechanical changes after turbo upgrades, but they must be installed by someone who knows what they're doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.It is one of the most costly upgrades but provides the best gains the debate is to go large single or a twin turbo setup. Upgrades to the 2JZ turbochargers - The most efficient approach to increase air supply, allowing you to burn more fuel and make more power.Mapping - remapping provides the most advantage in terms of cost savings, aftermarket ECUs, and piggyback ECUs are all alternatives this is best carried out after your other mods to fully release the power from your Supra.
