Most people will tell you under drive pullies are a waste of money. I haven't had any experience with them myself. But with cheap first mods, go with a cold air intake, offroad Y pipe and mufflers (if you don't have emissions where you live)

How much do want to spend?

Moroso "honker" intake.
Headers.
High flow cat and exhaust.
Better vlv springs then 1.6 ration rocker arms.
PCM tune - PCM for less, TPIS, Howell engineering.
At least 3.23 ration rear gear set.

That should keep u busy,

honestly in my opinion would be a stall and tune. then exhaust. all together net you about 15-20 rwhp and the stall will place you right in the torque curve. 2800 would be my opinion.

Id do full exhaust first. Like longtube headers, y pipe, high flow cat if need be, and a catback. Getting a stall would be a waste of money cause u build ur stall around ur power output. If u stall now and do more bolt ons ur power will go and ur stall will be useless. Do the tb coolant byepass and cai with a bew elbow.
