My final COG set up is 32/32 x 35mm and the 350Z 2.5 lipped aluminum idler pulley set (which is smaller than the plastic Stillen 3 inch). This set up will keep me out of the 12 lbs boost range. It is conservative, I would go all out but I like to drive my car every day. So i need it to be conservative.
For the serpentine belt on the front, I thought about running 10 rib but that is for another day. Hope this answers some of your questions. The reason my build is take F_ing for ever is the COG sizes, later I might drop to a 30 tooth on the SC side and slide my 34 Jack Shaft COG back on but not know.

You have really been a lot of help. I spend most of my time 1500 miles away from my car, so I cannot just walk outside and take measurments. I stock-pile parts, then throw them on when I get a little time at home.
I have decided to go forward with the Cogs sooner than later. I'm going to order your new setup and adjust the hp/tq with the front pulley. But, I would like to verify a couple of your new part numbers:
1) What is the part # of the 350Z 2.5" lipped alum idler pulley set?
2) Are both of your 32T pulleys the 2A033-032?
3) Is your 34T
JS pulley still the 4GR032-034?
4) Is the belt for the 34/30 combo still the 2A042-070 (70T, 350Z rev-up)?
5) What did you use to adjust the alignment on the Cog/Idler pulleys?

Thank you in advance. I appologize for being a pain in the butt. I need to Paypal you some cash for a 6-pack of beer for doing all of this test-fitting and info-sharing!
