from what I understand, it is just an INVERTED torx.

Some folks take a torx screw and weld it to a nut and use a regular socket to use the screw head for removal...

Hope that my help...

Don't know for sure, but this guy says the rotor Torx size is "really small" !

I would just buy a cheap set of Torx "screwdriver type" wrenches. I do know that the Opti torx screws do not require He-amn type torque, as so much of the unit is made of high impact plastic.....

If you haven't seen this web page, it shows the dis-assmebly procedure for the Optispark unit:

Good luck, I am about 2 weeks away from replacing my Opti and WP. Are you planning on pulling your Timing Chain cover, and replacing the O-ring seals??
just curious.....
