Opti vs coil

The Accels are gabage.
Underdrive pullies work better on vehicles that have a belt driven waterpump.
Very often optis just need a cap and rotor as any other distributor does periodically. MSD makes a cap and rotor kit that adds a vent to the unvented optis.
MSD cap and rotor kit will add venting and is under $150.

the complete msd replacement opti adds venting, though.

"This kit is supplied with a vacuum
line kit that will aid in venting the
distributor cap. One hose assembly
connects to a vacuum port on the
intake manifold while the other line
connects to the air inlet going into
the throttle body. In order to take
advantage of this venting technique,
you will need to seal the three small
holes on the bottom of the distributor."
