Best MOD for midrange to lower rpm gain. Neen a little more low end grunt.

NST Pulley Kit (Crank, Alt and Water Pulley). Would probably be the best for low-mid range and throughout the rpm range.

If you can only get one pulley, just get the NST 10% Underdrive Pulley if you don't intend to Supercharge later on. Its better for N/A and Turbo applications.

Yes deffinatly, i put the 10% underdrive pulley on by itself for awhile on my car (i had my water pump and altenator as well, but not installed) and already felt a difference. You can install this part by yourself no problem, takes about 1-2 hours depending how experienced you are. But right away, you feel better take off when you accelerate from a stationary position. Pick up is better, everything overall, #1 suggested first mod for all yaris's
