I bought a 36-1 on ebay which had a good outside diameter. Then I attached it to a golden eagle cam pulley. You can also weld it to a stock pulley. The d17 engine uses a 4+1 tooth pulley. Megasquirt supports that too.
i was looking at your post about running d17 ignition on a d16, did you make the cam trigger wheel too or was it bought. im looking into going cop, i was thinking about getting a d17 aem gear and swapping the center section with a d16 gear, you running a 60 -1 wheel? 24 -1?
