Sorry for the delay, I was out of town and I wanted to verify the part numbers before posting them for you. Don't want you to have to go back and forth for stuff.

1) Idler Pulley Set: 4GR116-300 $38.95

2) Jack Shaft:
a. 32tooth/4GR032-032 $94.00
b. 34tooth/4GR032-034 $94.00
COG's: 32tooth/35mm wide/ 24033-032 $94.00 *** Recommended, 35mm wide is not made in any other tooth size. They have a 30 tooth COG in a 50mm width. Which works if you build a support strut to keep the SC Plat from flexing under load.

4) Yes thats the size for 30/50mm SC COG & 34/20mm Jack Shaft COG. Also will work with 32/35mm SC COG & 32/20mm Jack Shaft COG: Belt is a Gates 20mm 70 tooth/ 2A042-070 $34.95

5) a. Idler Pulley (Smooth Aluminum w/Flang) is 4GR116-300 $38.95
b. When you buy the impeller get a set of shims. I didn't need any with mine but every SC is different. You might need to shim it to get the right clearances in the compressor. 928 Motorsports - Porsche® 928 Performance Parts - Set of 4 Impeller Shims for*Powerdyne, Vortech®, Paxton Superchargers - Porsche® 928 World record Holder 216.63537 mph
c. Pulley Spacers for the COG's not needed. What is needed is longer grade 8 bolt for the SC side, take the rib SC pulley off and take that bolt to Home Depot and match the threads. You will see what I mean when you take off the rib pulley from the SC the COG is wider depending on which one you use the 50mm is much wider than the 35mm. Will need a longer bolt.
d. Order a set of KEYS when you get your COGs. The keys keep the COGs from spinning on the shaft.
