Honestly you need to do a good bit of supporting mods being that you have an l32 with a gen v.


The list:

Some sort of intake (prefably a 9" cone filter)
180 t stat
Auto lite 104 spark plugs
Headers (speed daddy, or ssautochrome if your lookin to save some dough)
No cat
Resonator delete (optional)
Then most important SCAN

after that then worry about the pulley, also I'd suggest a tune afterwards
