All two of the not so local automotive machine shops here wanted $200, and they really didn't want to do it.

A machine shop should probably only charge you labor, around $80 an hour usually. They should only take 30min max including clean up, but some shops have an hour minimum. I'm a little worried they'll give me crap about surfacing and balancing it, as it'll be hard to chuck up now. But usually magnets are used for grinders, and hopefully they mount it via the bearing dia in the center to balance it.

1st picture I've taken, uploaded to photobucket, and posted via my iPhone, so forgive me if I doesn't work. There's a bit more material that coulda come off but not much.
I called the machine shop that's balanced my engine before, and they highly suggest balancing the pressure plate along with the flywheel. Which means I need to call SPEC and decide if I want a whole new clutch kit
or just the friction plate. And if I just get the friction plate, should I step up a stage or no. This all banks on wether or not they'll even sell just a friction plate. Anyone have experience with them about this?

Btw Joe, I saw some science show of some guys making a similar planetary gear setup for a motorcycle's front rotors, making them spin backwards. Cancels out most of the torque forces from the wheel, and made it much easier to lean.

Pistons have oil squirters. The crank scraper recondenses the oil vapor that occurs at high rpm. Its real world usefulness though I am not convinced of. I'd be more concerned with micro polishing things like valve stems, valve guides, lifter sides, lifter bores, etc.. There is a lot of frictional loss in those areas that would get you more power. I have never seen a gain in power from just installinga crank scraper that was beyond the margin of error of a dyno.

Resurfacing the flywheel they'll do on a Blanchard grinder and either use the center hole or a mag chuck. Balancing machines use their own mounting systems and I don't think that one will be any harder without the inner lip.
I just replaced the flywheel on my '97 with a Fidanza and on our cornerweight scales they were 17lbs stocker and 9lbs for the Fidanza.

The resurfaced and balanced it just fine, $94. They said the XTD pressure plate was pretty bad, and they did a bit of grinding to it, instead of just the flywheel. I don't think I took any pictures, it looks like the previous pictures except slighly shinier. The engines fully assembeled, and back in the bay. After a couple hours of hooking up electricals and plumbing, and I'll come back with results, assuming I can tell the difference with the little weight I took off. Oh, and I'll also report on whether or not the paper wp gasket worked.
