I designed my own disc this morning:
It is 0.2mm thick Stainless Steel Type 430C (Martensitic) using photochemical milling as the process. I was pretty foolish in thinking I could do it this way, as I'm sure Rob knows. The price per disc if I had one disc made would be $342 USD (171 GBP), yet the price per disc if I had 14 made would be $29.27 USD (14.60 GBP) which is about what Rob charges (minus shipping). If I had 50 made like Rob does, the price per disc goes down to $12.18 USD (6.10 GBP). I don't have that sort of money to spend on this sort of thing. =(
I wonder if there are 13 other people out there in a similar situation as me...
I could always try to start a group buy on the Sentra forums... But I doubt the interest would be high.
It looks like I'm back to square one.
I've given thoughts to purchasing a stock disc from Nissan and modifying it myself. I would join two or three holes together to make one larger hole, and I would blank out (somehow) a couple holes in between each enlarged hole. This could then be checked for balance on a high speed rotary tool (dremel). It might be worth it if I can get a disc cheaply. I'm going to call my parts guy and get a quote.
About the Bosch blue coil you mentioned. It seems like it would suit my needs just fine. I can purchase it for about $40 USD (20 GBP) shipped from
www.jcwhitney.com and upon searching for an MSD ignition coil, I found they are only about $10 USD (5 GBP) more than the VW coil, so that is what I will buy, and we can consider this ignition resistor problem solved. I could also get the car running, and then use the stock coil pack with the resistor and see how that works, so we will know if it is even a real issue or not. You know, for future generations. =]
So, if the quote for the stock CAS disc comes back, and it isn't too expensive, you can assume I am ready to purchase VEMS and associated things.
