DIYPNP here. Fidanza flywheel, working a/c. It's not a problem. Idle bumps to 1000rpms when A/C is on. GSlender code.

I have stock ECU but 10# FM Steel FW and A/C. You just have to learn how to drive two totally different cars. With A/C and without. :P

Planning on swapping to NB A/C components with a Sanden 505 compressor, though, so that should change.

Does the nb compressor run smoother?

The Sanden 505 isn't the NB compressor. It's a smaller unit that uses less power to turn. I'm also going to load it full of envirosafe Propane/Isobutane blend refrigerant, which works at lower pressures than R-12 or R-134a.

I'm going to use an NB condenser and evaporator, as both are parallel flow designs which are the highest efficiency for the most cooling, compared to the NA's serpentine condenser and tube and fin evaporator.

The goal is ice cold A/C that plays well with my super light flywheel. Throttle tip in varies a lot between no A/C and A/C on, and is worse when the A/C compressor suddenly kicks back on.

So which model Sanden 505 compressor has the mounting holes and dimensions like the Miata NB compressor?

There isn't one. You need to fab up some brackets.

I ended up getting a FX Racing Chromoly 11.7lb forged 4140 flywheel. After doing a lot of searching I found several good reviews. Some minor issues with pressure plate bolts not matching the factory bolts, but other than the usual "its ebaycrap, dont use it" no major issues that I could find. I did look for a descent used Fidanza, FM or 949 wheel with no luck.

This one looks very well made. Hopefully I will find some time to install this with the 949 sport clutch soon! I will report back once I get this on the road.

That's the one I've had since ~2009. I've found it to have no flaws.
Yes, the PP bolts are the same size as stock but a different thread pitch.

I finally got the flywheel and 949 Sport Organic Sprung clutch installed this past weekend. The flywheel went in fine and the supplied M8 bolts worked. The combination works very well so far. I will have to wait until I get at least a basic breakin period done before checking for any performance gains due to the lighter flywheel. I have noticed a quicker response when heel toe'ing and a slight (tolerable) increase in drivetrain noise when downshifting and engine braking. I believe the added noise is just part of going to a lighter FW and has nothing to do with it being an "ebay FW".

I really like the 949 Sport clutch so far. The pedal is only a little heavier, the only time I could really tell is when I got in my wife's stock 97 right after driving my 91. It has a great engagement feel and allows you to control the clutch much better than other racing on/off clutches I have driven in the past. I can't speak to it's torque capacity yet, but I should be way below the 260 ft/lb limit with my MSM turbo (only 190 ft/lb on virtual dyno). It is a great clutch that I would recommend for any sub 250 ft/lb setup.
