Good progress, mang.
While I e-high-five you for all you've done, I have to recommend that you to stay away from aftermarket crankshaft pulleys unless you're going to get a $400 Fluidampr. Reason being that the stock pulley also doubles as a harmonic dampner. If you take away the dampning effects of the harmonic dampner, you grenade your oil pump really quickly. Everyone knows what happens when your oil pump goes out... Not to mention, the engine vibrations that the stock dampner absorbs will be transferred right back into your crankshaft, rods, pistons, cams, block, head...shall I go on? Essentially rendering the entire engine useless for a rebuild.
I know that the N1 CTR uses an aluminum, single belt pulley, but that's because the race teams using the B16B for that single purpose have balanced and blueprinted everything to an extreme degree. And they dissasemble, inspect with all sorts of different methods, and rebuild the engines after every race. Unless you can afford to rebuild your engine every year, or 1.5 years, or even 6 months, I have to recommend using the stock pulley.
You can, however, take the pulley to a machine shop. They can hack off the two extra belt tracks and rebalance it for way cheaper than a Fluidampr, and even cheaper than just about any other aftermarket lightweight crankshaft pulleys.
